In 2017, North Korea unexpectedly staged a test launch of what was then a new ballistic missile , the Pukguksong-2. The launch took place when Japanese Prime Minister Shinzo Abe was on a state visit to the United States . There have been many more test launches of ballistic missiles by North Korea since. Between May and October 2019, North Korea launched as many as 12 ballistic missiles or other projectiles. But they have all been just test launches.

Things got real, though, on Jan. 7, 2020, when Iran launched more than a dozen ballistic missiles at two Iraqi military bases housing U.S. troops. This was not a test launch. It was Iran's retaliation for the U.S. drone strike that killed Iran Gen. Qassem Soleimani on Jan. 3, 2020. There were no casualties and Iran's Foreign Minister Mohammad Javad Zarif defended the missile strike on the U.S. bases in Iraq, saying it was an act of "self-defense."

But for the non-military minded among us, these ballistic missile launches — both the constant test launches in North Korea and the intentional strikes on U.S. bases in Iraq — may raise a good question: What exactly is a ballistic missile, anyway? Is there something about the ballistic part that makes a missile even more dangerous? After all, when someone freaks out we say they've "gone ballistic."

According to the Federation of American Scientists , a ballistic missile is one that has a ballistic trajectory over most of its flight path. What that means is that once the missile burns up the fuel that propels it, the missile keeps moving, the same way that a bullet does after it's been fired out of a gun. Once the fuel is gone, the missile's direction can't be altered. It follows a path determined by the speed of its launch and the force of gravity trying to pull it back toward the Earth's surface. Eventually, gravity guides the missile — and its payload, which might be an explosive, a chemical or biological weapon, or a nuclear device — down toward its target.

Ballistic missiles are different than cruise missiles. Cruise missiles are self-propelled for the majority of their time in the air, flying in a relatively straight line and at lower altitudes thanks to a rocket propellant. Think of a ballistic missile's flight path as a large arc up and back down again, while that of a cruise missile — fired from a warship, for instance — is closer to a straight line.

Ballistic missiles first came into use during World War II, when the Germans used a ballistic missile called the V-2 to attack London. British air defenses designed to stop aircraft couldn't stop the V-2s, because the rockets traveled too high into the upper atmosphere and moved too fast.

After the war, the U.S., with the help of captured German technology and scientists, built its own arsenal of even more powerful intercontinental ballistic missiles (ICBMs) capable of unleashing nuclear destruction upon targets on the other side of the world. The Soviet Union and China built ICBMs as well, setting up a world where a nuclear war was deterred by the prospect of mutual assured destruction.

The North Korean regime successfully tested intercontinental ballistic missiles (ICBM) in July and November 2017. Its Hwasong-15 ICBM reached an altitude of 2,780 miles (4,475 kilometers) and flew about 590 miles (1,000 kilometers) before landing in the sea off the coast of Japan. Analysts estimate the Hwasong-15 has a potential range of 8,100 miles (13,000 kilometers). If it's fired on a flatter trajectory, it could reach potentially reach anywhere on the U.S. mainland.

Which countries have intercontinental ballistic missiles?

What is meant by ballistic trajectory, what is difference between a ballistic and a cruise missile, how high do ballistic missiles fly, are ballistic missiles nuclear.

What is a cruise missile?

Cruise missiles, although similar to ballistic missiles in some regards, provide an alternate means to deliver a lethal payload rapidly and accurately to a target. Cruise missiles differ from ballistic missiles in that they fly towards their target at lower altitudes, remaining within the Earth’s atmosphere throughout their trajectory. Cruise missiles are defined as “an unmanned self-propelled guided vehicle that sustains flight through aerodynamic lift for most of its flight path and whose primary mission is to place an ordnance or special payload on a target.” [1] Unmanned aerial vehicles (UAVs) and unmanned control-guided helicopters or aircraft can be included in this definition [2] , but will not be discussed on this page.

The cruise missile has its beginnings in World War I, when the U.S. Army developed the Kettering Bug, an unmanned aerial bomb designed to strike targets beyond the range of artillery and too dangerous for piloted aircraft. However, the Kettering Bug was never used in combat. [3] Instead, the modern cruise missile originates more from the V-1 Flying Bomb used by the Germany in the last months of World War II. [4]

Launch Platforms

Cruise missiles are capable of being launched from multiple ground, air, sea and submarine platforms. Both fighter and long-range bomber aircraft are capable of carrying and launching cruise missiles. [5] On the ground, cruise missiles are most commonly launched by road-mobile systems due to the inherent advantages of mobility, but they can also be launched from fixed platforms. [6]

Russian warships in the Caspian Sea launch Kalibr cruise missiles towards targets inside Syria.

At sea, various surface ships and submarines can launch cruise missiles. Submarines are capable of launching while surfaced or submerged using torpedo fixtures or vertical launch tubes. [7] In April 2010 Kontsern-Morinformsistema-Agat, a Russian company, began marketing a version of the Russian Kalibr cruise missile housed in and capable of being launched from a standard shipping container. [8] This would allow any vehicle capable of carrying a standard shipping container to become a discreet platform from which to launch cruise missiles. [9]

Propulsion and Flight

Cruise missiles utilize jet engines as their primary method of propulsion. Most cruise missiles are subsonic and use Turbofan and Turbojet engines. While less common, supersonic and hypersonic cruise missiles utilize Ramjet and Scramjet engines. [10] Some also use rocket motor propulsion as a booster in the first phase of flight [11]  or to accelerate to supersonic speeds in the terminal phase. [12]

Cruise missiles can fly to their targets at varying altitudes as long as they remain within the atmosphere. The trajectory of most remains close to the Earth’s surface, sometimes skimming just meters above the ground. Their low flight path makes it much harder for most radar and sensor systems to detect the missile, unless the radar or sensor system is airborne and directed towards the ground. [13] Some cruise missiles will fly only at high altitudes and dive sharply down once they reach their target. Flying at high altitude can extend the range of the missile because it’s more fuel-efficient than flying at lower altitudes. However, this also makes the missile more susceptible to missile defense systems since today’s radars and sensors are typically positioned to detect and track high altitude threats. [14] Cruise missiles can also mix their flight trajectory between high and low altitude in order to get the benefits of both. In this instance, cruise missiles will typically fly at a high altitude early in their flight to help extend their range, but as they approach their target, or missile defenses, they will fly down to a lower sea skimming/terrain hugging altitude to help it evade detection and defenses. [15]

Cruise missiles can use multiple guidance methods in order to accurately place their ordinance on the desired target and avoid missile defense systems. One of the first methods used by cruise missiles was inertial guidance, which is still used today and allows the missile to fly along a flight path programmed prior to launch. [16] Another guidance method is terrain contour matching (TERCOM), which compares a terrain map to the current terrain the missile is flying over to ensure the missile is flying on the correct path. [17] Some use GPS systems, which require connection to either GPS or GLONASS satellite system, but can help ensure the missile follows the correct flight path and strikes the final target using specific coordinates with a high degree of accuracy. [18]

Other guidance methods are primarily used in the terminal phase of flight to increase accuracy. One is a laser guided system which uses a sensor to detect its target painted by a laser, however this can be unreliable because dust and smoke can interfere with the laser or the missile may not always be able to see the laser or painted target. [19] Another terminal guidance method is TV guidance, in which an operator uses a camera in the nose of the missile to visually identify and manually guide the missile to the target in its final phase. This method also gives the operator the option to abort the strike in the final phase if an anomaly is detected. [20]  A radar seeker is also used in the nose of some missiles to identify and/or keep the missile on target in the terminal phase. These radar seekers use either passive radar, which detect radar emissions of their target, or active radar, which emit their own radar to detect their target. [21] Infrared (IR) guidance – directing the missile towards heat emitting objects, such as engines [22] – may also be used by cruise missiles in the terminal phase. [23] However, because of its simplicity, IR guidance cannot differentiate between friendly, adversarial, or extraneous IR signals in a crowded battlefield, and is usually used in conjunction with other guidance systems. [24] The last guidance system used by cruise missiles is Digital Scene Matching Area Correlation (DSMAC), which uses a camera in the missile to find the desired target and match it to a stored image using an image correlator. [25]

Cruise missiles are typically armed with conventional or nuclear warheads, but can also be equipped with chemical or biological warheads. [26] The warhead weight and yield can vary widely, depending on the specific cruise missile and its mission.

What are the differences between a ballistic missile and a cruise missile.

Many countries choose missiles because they may be deployed efficiently against an enemy with a strong air defense system , making the use of human aircraft in such an attack impossible or too expensive. There is less need for personnel, supplies, and upkeep when using missiles instead of manned aircraft.

So, What are the Differences between a Ballistic Missile and a Cruise Missile?

When a missile test is being reported, the terms “ballistic missile” and “cruise missile” are frequently used. Ballistic and cruise missile systems are seen as emblems of national power and a cost-effective armament by many governments. Cruise and ballistic missiles are widely used by many countries, both offensively and defensively.

How do cruise missiles and ballistic missiles maneuver, and what are the differences between the basic principles of these maneuvers?

Guided cruise and ballistic missiles were first used when Germany attacked targets in England and Northern Europe with V1 cruise missiles and V2 ballistic missiles during World War II . Although these missiles were inaccurate, their use resulted in tens of thousands of Allied casualties.

The Federation of American Scientists says that a ballistic weapon follows a ballistic path for most of its flight. That means once the rocket’s fuel is gone, it will keep moving, just like a bullet does after being shot out of a gun.

Ballistic missiles climb very high, exiting the atmosphere. According to Wikipedia, short-range ballistic missiles stay within the Earth’s atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital trajectory.

According to one definition, a sub-orbital space flight reaches an altitude greater than 100 kilometers above the Earth’s surface. At this altitude, known as the Kármán line, once the fuel runs out, the missile’s direction cannot be altered; it follows a path based on the speed of its launch and the force of gravity attempting to pull it back to the Earth’s surface. Gravity eventually guides the missile and its payload toward its intended target, which could be a chemical or biological weapon or a nuclear device.

Ballistic missiles are broadly categorized into four groups based on their range:

• Short-range ballistic missiles cover distances less than 1,000 kilometers (approximately 620 miles).
• Medium-range ballistic missiles spanning 1,000 to 3,000 kilometers (approximately 620 to 1860 miles).
• Intermediate-range ballistic missiles range from 3,000 to 5,500 kilometers (approximately 1860 to 3410 miles).
• Intercontinental ballistic missiles (ICBMs) are capable of traveling over 5,500 kilometers, thus posing a threat to targets across the globe.

Top 10 Short Range Ballistic Missiles (SRBMs)

Short- and medium-range ballistic missiles are called theatre ballistic missiles, while ICBMs and long-range ballistic missiles are referred to as strategic ballistic missiles. On their flight path, ballistic missiles are capable of traveling at a high rate of speed. With terminal velocities of over 5,000 meters per second, an ICBM can strike a target within a range of 10,000 kilometers in approximately 30 to 35 minutes. Due to the limited time available, ballistic missiles are significantly more difficult to intercept than cruise missiles.

For example, the Russian RS-28 Sarmat ICBM can reach almost 25,000 kilometers per hour or over 15,000 miles per hour. To further complicate matters, most ICBMs carry not a unitary large warhead but several smaller and fully independent nuclear missiles called MIRVs (Multiple Independently Targeted Re-entry Vehicle). 

The Sarmat can carry up to 24 MIRVs; each MIRV carries nuclear warheads with yields ranging anywhere from hundreds of kilotons to a few megatons. Each MIRV can hit a target hundreds of kilometers away from each other, and some MIRVs will carry decoys and countermeasures, putting additional stress on defensive systems.

Even though cruise missiles are cheaper, more mobile, and more versatile, ballistic missiles are among the most feared armaments in existence. No nation has launched an ICBM as an act of war against another nation, although some nations have tested these missiles during training exercises.

Cruise missiles are unmanned vehicles that are propelled by jet engines, much like an airplane with turbofan engines, in particular being preferred due to their greater efficiency at low altitudes. They range in speed from subsonic to hypersonic, while less common supersonic and hypersonic cruise missiles utilize ramjet and scramjet engines. They can be launched from ground, airplane, and sea platforms like submarines and surface warships.

They tend to have shorter ranges than ballistic missiles. Unlike ballistic missiles, cruise missiles are usually categorized by intended missions and launch mode instead of maximum range. The two broadest categories are land attack cruise missiles (LACMs ) and anti-shipping cruise missiles (ASCMs) . The success of U.S. Tomahawk cruise missiles during the Persian Gulf War has heightened interest in cruise missile acquisition in many countries.

Cruise missiles can reach their objectives from a variety of altitudes so long as they remain within the atmosphere. The trajectory of the vast majority of objects remains close to the Earth’s surface, occasionally hovering just meters above the ground. Their low flight path makes it difficult for most radar and sensor systems to detect the missile unless the radar or sensor system is airborne and directed toward the ground.

Some cruise missiles can only fly at extremely high altitudes, and then they descend steeply once they’ve reached their destination. Higher-altitude flight uses less fuel than lower-altitude flight, allowing the missile to travel further. Unfortunately, modern radars and sensors are often set up to identify and track threats at high altitudes, making the missile more vulnerable to missile defense systems.

Altitude Variation for Tactical Advantage

Cruise missiles are renowned for dynamically altering their flight trajectory, capitalizing on both high and low altitudes. This strategic maneuver enhances their overall performance by combining the advantages of different altitudes. Typically, these missiles initiate their journey at high altitudes to extend their operational range. 

However, as they near their target or potential missile defenses, they adeptly descend to lower altitudes, skimming the sea or terrain. This transition serves to elude detection and countermeasures, highlighting the adaptability of cruise missiles in various operational scenarios.

Precision Strikes Defined

The hallmark characteristic of cruise missiles lies in their remarkable precision. Often boasting ranges under 300 kilometers, with the most extended variants reaching approximately 1600 kilometers, these missiles exhibit extraordinary accuracy. 

A frequently cited example underscores this accuracy, asserting that cruise missiles can cover a thousand miles and hit a target as compact as a single-car garage. This precision opens avenues for surgical strikes and minimizes collateral damage in contemporary warfare.

Guidance Mechanisms for Pinpoint Accuracy

Cruise missiles harness a repertoire of guidance methods to ensure the impeccable placement of their payloads on intended targets while outmaneuvering missile defense systems. Among these methods, inertial guidance stands as a foundational approach, relying on a pre-programmed flight path set before launch.

Terrain Contour Matching (TERCOM): Navigating with Terrain

Another pivotal guidance method is Terrain Contour Matching (TERCOM) . This intricate mechanism involves the comparison of an onboard terrain map with the actual topography over which the missile traverses. This technique guarantees the missile’s adherence to the designated path, further reinforcing its accuracy and operational efficacy.

Precision Through Global Positioning: GPS and GLONASS

Several cruise missiles integrate GPS systems to achieve pinpoint accuracy. These systems necessitate connectivity with the GPS or GLONASS satellite networks and facilitate adherence to predetermined flight paths. Cruise missiles can strike designated targets with unparalleled precision by leveraging specific coordinates, augmenting their role in modern warfare.

Enhancing Terminal Phase Precision

Cruise missiles deploy advanced guidance methods in the terminal phase of flight to elevate their accuracy.

Laser-Guided Precision: Target Painting

Laser-guided systems emerge as a crucial asset in this phase. Equipped with sensors, these systems detect targets designated by laser markers. While immensely accurate, this method can be vulnerable to interference from environmental factors such as dust and smoke, potentially hindering target acquisition.

TV Guidance: Human Intervention

Terminal guidance can also involve TV guidance, where an operator employs a nose-mounted camera to identify the target and manually guide the missile visually. This dynamic approach allows operators to abort the strike if anomalies are detected, underscoring the human element in precision warfare.

Radar Seekers: Radar-Equipped Accuracy

Certain cruise missiles integrate radar seekers in their nose sections to identify and remain on course toward their targets during the terminal phase. These seekers may utilize passive radar to detect emissions from the target’s radar or active radar to emit signals for target detection.

Infrared (IR) Guidance: Homing in on Heat

Infrared (IR) guidance presents yet another terminal phase technique, steering missiles toward heat-emitting sources like engines. Despite its efficacy, IR guidance’s simplicity renders it incapable of distinguishing between friendly, adversarial, or extraneous IR signals in crowded battlefields. Consequently, it is often employed alongside other guidance systems.

Digital Scene Matching Area Correlation (DSMAC): Image-Reliant Precision

Among the diverse guidance methods, Digital Scene Matching Area Correlation (DSMAC) relies on an onboard camera to identify the target. This image is then compared to a stored reference image using an image correlator, accentuating the missile’s ability to refine target identification during the terminal phase.

Cruise Missiles: Transformative Force in Modern Warfare

Cruise missiles hold a pivotal role across all military branches, reshaping the landscape of modern warfare. Their effective utilization in contemporary conflicts has the potential to sway the outcome without resorting to nuclear options. 

As technology advances, the horizon holds promises of more intelligent, self-managing, and hypersonic cruise missiles entering the global market. Irrespective of these changes, cruise missiles are poised to endure as one of the most dependable weapons in the foreseeable future.

Ballistic Missile Meaning

These are based on rocket technology, to maximize range they are fired at 45 degree, the long range ballistic missile are known as re-entry vehicles because they complete their journey in endo and exo atmosphere. They have three phases to take off midcourse, race and termination.

Classification of Ballistic missile

These are classified on various parameters i.e. Nature and Range.

• Nature – on the basis of nature they are surface to surface, surface to air, and air to air missiles.
• Short-Range Ballistic Missiles (SRBMs ) : These missiles range up to 700 km, it is a single stage solid fuel based. Examples : Iskander Missile (Russia), DF21 (China), LORA (Israel), Ghaznavi (Pakistan), Prithvi missile (India).
• Medium-Range Ballistic Missiles (MRBMs) : These missiles range range between approximately 1,000 and 3,000 kilometres (620 to 1,860 miles). Example Hwasong-12 (North Korea), Agni 1 (India), Khoramshahr 4 (Iran).
• Intermediate-Range Ballistic Missiles (IRBMs) : IRBMs missiles have a range between around 3,000 and 5,500 kilometres (1,860 to 3,420 miles). Example : Agni missile 2, 3, 4.
• Intercontinental Ballistic Missiles (ICBMs) : ICBMs have the longest range exceeding 5,500 kilometres (3,420 miles). They are designed to travel across continents or even around the world.

Cruise missile

Cruise Missile is based on jet technology. Travels only in endo atmosphere, and move parallel to earth’s surface therefore airborne radars are completely effective in detecting them. These missiles are equipped with guidance systems.

Classification of Cruise missile

• Subsonic : These are guided missile that travels at speeds slower than the speed of sound, which is approximately 343 meters per second (or 1,125 feet per second). Example Nirbhay, Tomahawk, Harpoon Missile.
• Supersonic Missile : travels at speed which is more than speed of sound. Example Brahmos, kh 47m2 Kinzhal.
• Hypersonic : Travels at speeds which is greater than the speed of sound. Speeds are generally considered to be Mach 5 (five times the speed of sound) or faster. Example : Brahmos 2,  Kh-47M2 Kinzhal.

Nirbhay Missile

• It is India’s subsonic cruise missile with speed of 0.7 mach with range of 1100- 1300 km.
• It is nuclear capable and operated on principle of fire and forget.
• Nirbhay missile is not a stalled missile but to avoid detection from radar if enemy, it follows tree top trajectory.
• It is that uncomfortable fight for enemies’ radar which makes it difficult for them to detect consignment.

Tomahawk Missile

• It is a USA subsonic cruise missile with speed of 0.74 mach with range of approximately 2400 km.
• Tomahawk is a long range, all weather missile, primarily used by the United States of America Navy.
• It has an Inertial Navigation System , flies at very low altitude and during flight it can be reprogrammed to change target.

Brahmos Missile

• Fastest cruise missile in the world in its category.
• The Brahmos missile speed is Mach 2.8 and has a range of 290 kilometres, or approximately three times the speed of sound.
• The Brahmaputra and Moskva rivers in Russia inspired the its name, which was jointly developed with Russia.

Introduction

To define the impact of unmanned aerial systems on current and future NATO operations, it is very important to identify which kind or category of threats are included and which are not. This section will try to clarify this definition and will show that a clear classification is sometimes not easy to achieve.

A threat is typically defined as the combination of malevolent intent and the ability to put it into action. Further subcategories of this overarching term exist, such as ‘air threat’ to better describe the operational environment and to categorize or delineate measures, like ‘air defence’ to counter the respective threat. The set of all capabilities that qualify as air threats is so diverse and complex that no singular system can be used to execute air defence. Additionally, the question of what constitutes an air threat is not an easy one. Is an air threat any capability that uses the air as its main or final domain for effect delivery? If that were the case, a projectile from a rifle would be an air threat, which is not the case. However, the defence against larger projectiles like artillery shells or mortar rounds, which are a typical ground threat, finally became part of air defence considerations after Counter-Rocket-Artillery-Mortar (C-RAM) systems had been developed and fielded.

Defining Unmanned Aircraft

Since this document is about the threat of Unmanned Aircraft Systems (UAS), the term Unmanned Aircraft (UA) needs to be looked at. Currently, NATO defines UA as an aircraft that does not carry a human operator and which is operated remotely using various levels of automated functions. 1 UA can be expendable or recoverable and may carry lethal or non-lethal payloads. Of note, cruise missiles are categorically excluded from this NATO definition. As this definition is very broad, the term aircraft needs to be described for a better understanding. The ICAO (International Civil Aviation Organization) defines an aircraft as any machine that can derive support in the atmosphere from the reactions of the air other than the reactions of the air against the earth’s surface. 2

By this portrayal alone, all projectiles that only have initial propulsion and then just follow a ballistic trajectory (e.g. bullets, artillery shells, regular bombs or ballistic missiles) can be excluded from the aircraft category. For the purpose of this paper, also ordnance which uses aerodynamic lift or other interactions with the atmosphere just to extend the ballistic flight path will be excluded from the UA category as well. This removes threats like gliding bombs or hypersonic glide vehicles from the UA set, although they could be remotely operated and definitely possess automated functions. Emerging technologies (e.g. new propulsions, swarming or Artificial Intelligence) might create fringe threat sets, which generally show UA properties, but are currently not considered as such.

An extended definition proposal of Unmanned Aircraft (UA)

Vehicles that use aerostatic or aerodynamic lift, and overall don’t generally fly on a ballistic trajectory can be categorized as an aircraft. These vehicles can be propelled by a  motor (e.g. rotary or jet) to create lift and sustain flight. If these aircraft do not house a pilot within the airframe and are operated remotely using various levels of automated functions, they are considered an UA, excluding cruise missiles.

Cruise Missiles versus Unmanned Aircraft

In general, making the distinction between ordnance and UA is not useful, due to tremendous technical progress. These two categories are not exclusive anymore, while not every ordnance is a UA, a UA can be used as ordnance. In times of mass production, innovative propulsion systems and reliable effect delivery without a pilot on board, the idea of using the vehicle as ordnance itself became more prevalent. While the V1 in WWII initially had a CEP (Circular Error Probable) of more than 10 km and most use cases were aimed at producing terror, today´s cruise missiles have a CEP of 10 meters or less. The cost/benefit ratio between losing the UA while creating a certain effect or enabling it to deliver the same effect while remaining retrievable has shifted significantly in times of precise technological options and relatively cheap production cost, especially for small UA.

Drone versus Unmanned Aircraft

The terms ‘Unmanned Aircraft’ and ‘Drone’, as well as variations such as ‘Unmanned Aerial Vehicle (UAV)’ 3 or ‘Remotely Piloted Aircraft (RPA)’ 4 are often used interchangeably but are actually deliberately defined to reflect certain classes, attributions or certifications of the unmanned systems.

When having to counter these systems, the most relevant factors are overall system complexity and aircraft size. Therefore, this book summarizes the different categories and classes of unmanned systems under the following two terms:

Unmanned Aircraft

The term ‘Unmanned Aircraft’ describes the overall set of vehicles, as described above. However, this book uses the term ‘UA’ to address military systems falling into the NATO Class II and III categories. UA are typically part of a complex system that can include dedicated Ground Control Stations, Mission Control Elements, multiple aircrews, military-grade communication systems, as well as dedicated infrastructure for logistics and maintenance. UA are usually operated by well-trained personnel, often qualified pilots, to safely operate alongside other airspace users. When addressing not only the aircraft but also other system components or the system as a whole, this book uses the term ‘Unmanned Aircraft System’ or ‘UAS’.

The term ‘drone’ is commonly used and widely accepted in the civil domain for all kinds of unmanned systems. Hence, this book uses the term ‘drone’ to address all types of consumer and commercial systems, which are generally smaller and less complex than their military counterparts. ‘Drone’ implies that the system is typically operated by a single, not necessarily qualified individual, from a handheld remote control, in relatively close proximity to the aircraft, and under Line-of-Sight (LOS) conditions. Therefore, this book also uses ‘drone’ for most military systems falling into the NATO Class I category, as their size and complexity is quite comparable to commercially available consumer models and therefore require a similar approach when having to counter them.

‘Unmanned Aircraft’, Record #7915, NATO Terminology Database, [Online]. Available: https://nso.nato.int/natoterm/Web.mvc. [Accessed 15 Jul. 2019].

International civil aviation organization (icao), ‘international standards and recommended practices, annex 6, operation of aircraft, part i’, 25 feb. 2013. [online]. available: https://www.icao.int/safety/fatiguemanagement/frms%20tools/amend- ment%2037%20for%20frms%20sarps%20%28en%29.pdf. [accessed 15 jul. 2019]., the term unmanned aerial vehicle (uav) is no longer in use by nato but is often still used in the civil and public domain., the term remotely piloted aircraft (rpa) is used to indicate that the ua is required to be controlled by a pilot who has been trained and certified to the same standards as a pilot of a manned aircraft..

Why it’s so hard to defend against cruise missiles

A recent conference raises the question: What kind of threat does this type of weapon pose to the United States?

By Kelsey D. Atherton | Published Jul 25, 2022 7:00 AM EDT

On July 14, the Center for Strategic and International Studies in Washington, DC held a one-day conference premised on a specific threat: What if, in the future, war comes to the United States via cruise missile? Pointing to new developments in cruise missile technology, and the limitations of existing early warning systems that are focused on the high arcing trajectories of ballistic missiles, the CSIS conference and accompanying report suggests that to defend the continental United States from such a threat, the military should adapt and deploy the kind of cruise missile defenses presently used as regional weapons.

Unlike ballistic missiles, which arc up into space before traveling back down towards earth, cruise missiles fly close to the ground, making it hard for radar on the ground that’s pointed up at space to see them.

The perceived threat from new cruise missiles is driven by tech developments occurring across the globe, as new materials, better aerodynamics, and sophisticated sensors and guidance systems make possible the fielding of weapons, like hypersonic missiles , that had mostly been just theoretical decades ago.

For the United States, the development of long-range bombers in the 1940s, followed by the development of intercontinental ballistic missiles, shattered the notion that the enormous distances of the Atlantic and Pacific oceans were enough to protect the continental US from direct attack. (During World War II, US territories in the Pacific came under direct attack, but the only long-range assault on the 48 states came in the form of incendiary-carrying balloons launched by Japan into the jet stream and carried over to the US.)

With atomic and then thermonuclear payloads, bombers and long-range missiles threatened devastation on an unprecedented scale, and the United States built an elaborate system of early warning sensors focused on detecting early signs of launch, and expanded its first-in-the-world nuclear arsenal to deter attack. North American Aerospace Defense Command (NORAD) is run by both Canada and the United States, and maintains a series of radars and other sensors designed to detect early attacks across the Arctic or elsewhere. (Every December, NORAD highlights its existence by tracking Santa Claus, turning a system designed to detect oblivion into a kid-friendly Christmas tradition .)

At the conference held by CSIS, the threat from cruise missiles was discussed as a way that other countries could attack the United States that is hard to detect by employing existing, ICBM-focused measures. It is also considered hard to deter through threat of nuclear retaliation, operating on the assumption that if a cruise missile with a conventional warhead destroyed a building or killed people in the United States, the President would not immediately respond with a nuclear strike.

“You know, our adversaries are building diverse, expansive ranges of modern offensive missile systems, and we see them – we see them in the news every day,” Stan Stafira, Chief Architect of the Pentagon’s Missile Defense Agency, told the panel. “They’re capable of maneuvering in the midcourse and the terminal phases of their flight, like maneuvering reentry vehicles, multiple independent reentry vehicles, hypersonic glide vehicles, and cruise missiles.”

Part of the broader appeal of hypersonic weapons to nations like Russia, China, and the United States is that the speed and trajectories of the missiles make them harder to detect than ICBMs. The ballistic arc of ICBMs means the launch is visible to radar while it is still ascending, once it clears the horizon line. Meanwhile, both hypersonic glide vehicles and hypersonic cruise missiles, which travel at Mach 5 or above, are designed to fly below that radar horizon, with the cruise missile keeping a close trajectory to earth and the glide vehicle flying in the high atmosphere.

“I want to state that we absolutely believe that nuclear deterrence is the foundation of homeland defense,” said Lieutenant General AC Roper, deputy commander of Northern Command, the part of the US military responsible for North America. “However, we also must have credible deterrence options below the nuclear thresholds, options which allow for a balanced approach of deterrence by denial and deterrence by punishment or cost imposition.”

Deterrence, at its most straightforward, is a strategy of making a big threat on a condition: One country publicly declares it will launch nukes at another if it launches nukes at it, with the intended effect that neither country launches nukes. But because the payload of a cruise missile—it could be nuclear or conventional, unlike ICBMs, which are always nuclear—is unlikely to be known until impact, generals like Roper would prefer to have a range of weapons with which to respond.

Missile defense is one of those options, and the US already employs a few forms. Part of any missile defense system is the sensors, like specially focused radar, that can detect incoming attacks, and then track those weapons as they travel. These radars then send that tracking information to interceptors, which are missiles launched to fly and destroy the incoming attacking missile. Shooting missiles at other missiles is a hard problem because an incoming threat arrives at great speed, and because the cost calculus can favor an attacker. Interceptors, like shorter-ranged Patriot missiles or longer-ranged ballistic interceptors , are often more expensive than the missiles they are intercepting. And unlike interceptors, which have to hit precisely to work, missiles launched in attack can deploy decoys or countermeasures to redirect interceptors away, or can instead be fired in a greater volume, overwhelming interceptors through sheer numerical advantage.

“The resulting 20-year cost to provide even a light defense of a vast area ranged from $77 billion to $466 billion,” reads the CSIS report , citing an analysis from the Congressional Budget Office studying a range of cruise missile defense options. “The considerable cost variation is due to alternative combinations of sensors and interceptors and varying desired warning times of 5 or 15 minutes.”

What’s the difference between a cruise missile and a ballistic missile?

• By Alex Hollings
• January 7, 2022

Share This Article

It’s not at all uncommon to see news stories featuring discussions about missile platforms and their capabilities, from Darpa’s recent test of a hypersonic cruise missile to discussions about the destructive power of Russia’s latest intercontinental ballistic missile, the RS-28 Sarmat . As a result, you may have found yourself wondering… what exactly is the difference between a ballistic missile and a cruise missile ?

In the interest of brevity, you can really sum up the difference between these types of weapons with the trajectory that they follow. A ballistic missile follows a “ballistic flight path,” which often includes traveling along a long arc, whereas a cruise missile tends to follow a straighter, lower altitude trajectory. Another easy (if not exactly precise) way to think about them is that ballistic missiles are more like rockets, while cruise missiles are more like aircraft or drones.

Ballistic missile basics

While both ballistic and cruise missiles can carry nuclear payloads, the most commonly understood (and feared) nuclear weapon delivery vehicle of the modern era falls under the ballistic category: the ICBM. And while there are many variations in the employment of different sorts of ballistic missiles, the ICBM model offers a simple way to appreciate the concept behind a “ballistic flight path.”

A ballistic missile is propelled into the air by a rocket motor, or often (as is the case with ICBMs) multiple staged rocket motors. ICBMs bear a striking resemblance to the rockets that take astronauts into space for good reason, other than the payloads these platforms carry, they are mechanically very similar.

Related: What exactly is America’s nuclear triad?

These rocket motors carry the ballistic missile to a high altitude (boost phase) until the rocket fuel is entirely expended. At that point, known as the midcourse phase, the missile reaches its highest altitude before it begins to travel back down its arced flight path. For ICBMs, this phase can last up to 20 minutes, with the missile itself traveling at speeds of around 15,000 miles per hour.

It then begins its unpowered descent, known as the terminal phase, traveling at speeds of nearly 2,000 miles per hour until it collides with its target.

Cruise missile basics

Unlike the long arcing trajectory of a ballistic missile, a cruise missile travels at lower altitudes and on far straighter trajectories. In fact, it might be easiest to think of a cruise missile as a drone of sorts that flies on its own to its intended target and then proceeds to crash into it. Perhaps the most commonly discussed cruise missile in modern use is the Tomahawk, which has become America’s weapon of choice for engaging targets at fairly long distances without deploying troops to a conflict.

Cruise missiles don’t leave the atmosphere at any point during their flight, nor do they travel unpowered for any significant duration. Rather than rocket engines, cruise missiles are powered by turbofans just like many tactical aircraft, and most often, even have wings that deploy after they’ve launched. Some cruise missiles can even be guided into their target by remote operators using cameras on the weapon’s nose, again, not unlike piloting a drone or UAV.

Modern cruise missiles are known for their range and excellent accuracy. In fact, the common rule of thumb regarding these weapons is, “It can fly 1,000 miles and hit a target the size of a single-car garage.”

Difference Between Cruise and Ballistic Missiles

Cruise missiles are guided, low-altitude, and precise. Ballistic missiles are unguided, high-speed, long-range, and follow a high trajectory. Check Difference between Cruise and Ballistic Missiles.

Table of Contents

Cruise missiles are guided, jet or propeller-driven projectiles that can fly at low altitudes, follow a flexible path, and are capable of precision strikes. Ballistic missiles, on the other hand, are unguided, rocket-powered weapons that follow a high, arching trajectory before descending toward their target. They are typically much faster and have longer ranges, but they lack the in-flight manoeuvrability of cruise missiles, making them more suitable for long-range and strategic strikes.

Recently North Korea continued its weapons testing, firing cruise missiles amidst escalating tensions and “war preparations” against South Korea. Know the Difference between Cruise and Ballistic Missiles in This article.

Cruise Missiles

Cruise missiles are self-propelled, guided weapons that can be launched from various platforms, including aircraft, ships, or ground-based launchers. They are designed to fly at low altitudes and can be programmed to follow a specific flight path, often hugging the terrain, which makes them difficult to detect and intercept. Cruise missiles can carry various types of warheads and are used for precise, long-range strikes on specific targets, such as military installations, infrastructure, or high-value targets. Their ability to navigate and adapt during flight provides them with a high degree of accuracy.

Examples of Cruise missiles

• Tomahawk: The United States Navy’s Tomahawk cruise missile is one of the most well-known examples. It’s used for long-range precision strikes and can be launched from ships and submarines.
• BrahMos: A joint venture between India and Russia, the BrahMos cruise missile is one of the fastest supersonic cruise missiles in the world.
• AGM-86 ALCM: The United States Air Force employs the AGM-86 Air-Launched Cruise Missile as a nuclear-armed cruise missile.
• Storm Shadow / SCALP: Developed by France and the UK, this air-launched cruise missile is used for precision strikes against high-value targets.
• Kalibr: A family of cruise missiles used by Russia, including anti-ship, land-attack, and anti-submarine variants.
• JASSM: The Joint Air-to-Surface Standoff Missile, used by the United States and several other countries, is designed for precision strikes against high-value, well-defended targets.

Ballistic Missiles

Ballistic missiles are unguided rockets that follow a high, parabolic trajectory when launched, ascending into space and then descending rapidly toward their target. They can carry nuclear or conventional warheads and are categorized based on their range: short-range, medium-range, intermediate-range, and intercontinental-range missiles.

Ballistic missiles are known for their high speed and long-range capabilities, making them suitable for delivering strategic or long-range strikes. Unlike cruise missiles, they lack in-flight manoeuvrability but rely on their high velocity and trajectory to reach their intended targets. They are a key component of many countries’ military arsenals.

Examples of Ballistic Missiles

• Intercontinental Ballistic Missile (ICBM): The Minuteman III ICBM used by the United States is a prime example, designed for delivering nuclear payloads over intercontinental distances.
• Submarine-Launched Ballistic Missile (SLBM): The Trident II D5, used by the U.S. Navy, is an example of an SLBM capable of being launched from submarines.
• Medium-Range Ballistic Missile (MRBM): The Russian Iskander-M is an MRBM used for shorter-range precision strikes.
• Short-Range Ballistic Missile (SRBM): The North Korean Hwasong-15 is an example of a SRBM with an extended range, designed for regional threats.
• Intermediate-Range Ballistic Missile (IRBM): The Chinese DF-26 is an example of an IRBM designed for regional and strategic purposes.

What is the difference between Ballistic Missile and Cruise Missile?

There are two major types of missiles- ballistic and cruise. the article below enlists the difference between the two categories and details it. take a look at the difference between cruise missile and ballistic missile below. .

Ballistic Missiles vs Cruise Missiles: About

Ballistic Missile:

Any missile is called Ballistic when the trajectory it follows is ballistic. It is used to deliver one or more warheads on a predetermined target. 

A ballistic trajectory is the path of any object that is launched but with no active propulsion during its actual flight. Thus in such missiles the trajectory has to be fully determined by a given initial velocity, effects of gravity, air resistance and earth's motion. 

Cruise Missile:

It is a guided missile where the target is pre-set. It is basically used against terrestrial targets. 

Such missiles are  designed to deliver a large warhead over long distances with high precision.

Difference between Ballistic Missile and Cruise Missile:

Cruise Missiles type:

Hypersonic (Mach 5): These travel at least five times the speed of sound (Mach 5).

Supersonic (Mach 2-3): These missiles travel faster than the speed of sound.

Subsonic (Mach 0.8): These missiles travel slower than the speed of sound.

Ballistic Missile Type:

Short-range (tactical) ballistic missile (SRBM): 300 km to 1,000 km range

Medium-range (theatre) ballistic missile (MRBM): 1,000 km to 3,500 km range

Intermediate-range (Long-Range) ballistic missile (IRBM or LRBM): 3,500 km to 5,500 km range

Intercontinental ballistic missile (ICBM): Above 5,500 km range

We frequently notice news related to ballistic missiles, cruise missiles and various missile systems of India. Memorizing names and salient features of various Indian missiles is hard without having a broader understanding of the concept of ballistic missiles and cruise missiles, and major missile defence systems. It is better to give these concepts a holistic structure rather than learning them in bits and pieces.

Ballistic Missile vs. Cruise Missile

The Hindu | GS3 > indigenization of technology

The terms ‘ballistic missile’ and ‘cruise missile’ appear in news articles wherever there is a missile test. It is essential for us to understand these terms to understand various Indian missile defence systems.

Ballistic Missile

• A ballistic missile follows a ballistic trajectory to deliver one or more warheads on a predetermined target.
• A ballistic trajectory is the path of an object that is launched but has no active propulsion during its actual flight (these weapons are guided only during relatively brief periods of flight).
• Consequently, the trajectory is fully determined by a given initial velocity, effects of gravity, air resistance, and motion of the earth (Coriolis Force).

Image Credits: Wikipedia

• Shorter range ballistic missiles stay within the Earth’s atmosphere.
• Longer-ranged intercontinental ballistic missiles (ICBMs), are launched on a sub-orbital flight trajectory and spend most of their flight out of the atmosphere.

Types of ballistic missiles based on the range

• Short-range (tactical) ballistic missile (SRBM): Range between 300 km and 1,000 km.
• Medium-range (theatre) ballistic missile (MRBM): 1,000 km to 3,500 km.
• Intermediate-range (Long-Range) ballistic missile (IRBM or LRBM): 3,500 km and 5,500 km.
• Intercontinental ballistic missile (ICBM): 5,500 km +

Cruise missile

• A cruise missile is a guided missile (target has to be pre-set) used against terrestrial targets.
• It remains in the atmosphere throughout its flight.
• It flies the major portion of its flight path at approximately constant speed.
• Cruise missiles are designed to deliver a large warhead over long distances with high precision.
• Modern cruise missiles are capable of travelling at supersonic or high subsonic speeds, are self-navigating, and are able to fly on a non-ballistic, extremely low-altitude trajectory.

Types of cruise missiles based on speed

• Hypersonic (Mach 5): these missiles would travel at least five times the speed of sound (Mach 5). E.g. BrahMos-II.
• Supersonic (Mach 2-3): these missiles travel faster than the speed of sound. E.g. BrahMos.
• Subsonic (Mach 0.8): these missiles travel slower than the speed of sound. E.g. Nirbhay.

Differences between Ballistic Missile and Cruise Missile

Integrated guided missile development programme (igmdp).

PIB | Source | The Hindu | 19-06-2019 | GS3 > indigenization of technology

• IGMDP was conceived by Dr. A P J Abdul Kalam to enable India attain self-sufficiency in missile technology.
• IGMDP was conceived in response to the Missile Technology Control Regime that decided to restrict access to any technology that would help India in its missile development program.
• To counter the MTCR, the IGMDP team formed a consortium of DRDO laboratories, industries and academic institutions to build these sub-systems, components and materials.
• IGMDP was started in 1983 and completed in March 2012.
• Keeping in mind the requirements of various types of missiles by the defence forces, the development of five missile systems was taken up.
• Prithvi: Short-range surface-to-surface ballistic missile (Prithivi means Earth Surface to Surface)
• Agni: Intermediate-range surface-to-surface ballistic missile
• Trishul: Short-range low-level surface-to-air missile
• Akash: Medium-range surface-to-air missile (Akash means Sky Surface to Air)
• Nag: Third generation anti-tank missile (Nag means Snake Nag slithers like a Snake to hit a tank!)
• After its success, the Agni missile program was separated from the IGMDP upon realizing its strategic importance.

SLBM: Sub-marine launched ballistic missile

Prithvi Missiles

All the Prithvi variants are surface-to-surface SRBMs.

Agni Missiles

MIRV: Multiple Independently targetable Re-entry Vehicle

Anti-satellite weapons (ASAT)

• In March 2019, India successfully tested its ASAT missile.
• The ASAT missile destroyed a live satellite in Low Earth orbit (283-kilometre).
• As per DRDO, the missile is capable of shooting down targets moving at a speed of 10 km per second at an altitude as high as 1200 km.

The Iran-Israel Air Conflict, One Week In

Critical Questions by Shaan Shaikh

Published April 19, 2024

On April 13, Iran launched a large salvo of missiles and drones at Israel. Designated “Operation True Promise,” the attack reportedly included around 170 drones, 120 surface-to-surface ballistic missiles, and 30 cruise missiles. It came in retaliation to an Israeli airstrike on April 1 against an Iranian diplomatic base in Damascus, Syria, which killed seven officers of the Islamic Revolutionary Guard Corps (IRGC), including the Quds Force’s General Mohammad Reza Zahedi. Iran’s attack marked the first time that Tehran has directly attacked Israel from Iranian territory.

On April 18, Israel responded in turn with airstrikes near Isfahan and Tabriz, Iran. Details on this attack are still coming in. Unconfirmed imagery suggests Israel struck at Iranian targets with some number of Sparrow air-launched ballistic missiles. Iranian leaders have claimed that their air defenses fended off the attack, which is unlikely but signals that they will not respond.

Q1: What missiles and drones did Iran use?

A1: Identifying missiles used in combat is hard. Identifying Iranian missiles, which come in a bewildering, visually similar number of derivatives and modifications, is even harder.

Iranian state-run media has claimed the use of the Emad and Kheibar Shekan-1 ballistic missiles, Paveh cruise missiles, and Shahed drones. Other reports mention possible use of the Ghadr ballistic missile. The drones employed are widely reported as Shahed-131 and -136 variants.

Brigadier General Hajizadeh, commander of the IRGC Aerospace Force, stated that Iran did not use its supposedly higher-end Khorramshahr, Sejjil, Kheibar Shekan-2, or Fatah ballistic missiles. The Washington Post has added that Iran did not appear to launch the Shahab-3.

Q2: Did Iran intend to limit Israeli casualties?

A2: Somewhat. U.S. and Iranian leaders reportedly engaged in back-channel conversations to discuss redlines and expectations over the past few weeks. Iranian leadership publicly warned about the forthcoming attack, and Iranian foreign minister Hossein Amir Abdollahian claims to have given neighboring countries 72-hour notice before the attack. Once Operation True Promise commenced, incoming drones appeared on social media hours before reaching Israel.

To be sure, Iran’s decision to fire over 300 projectiles at Israel still suggests a high acceptance of risk for casualties, damage, and further escalation. Following reports of air defense success, one IRGC leader claimed that Iran used older and less sophisticated missiles in its attack. Perhaps this is why one U.S. official found that roughly 50 percent of Iran’s ballistic missiles failed on launch or in flight. However, it is difficult to validate Iran’s claim. It is doubtful that Iran held off using Khorramshahr missiles, for example, to avoid additional escalation risks.

Media reports have also exaggerated Iran’s intentions to limit casualties in the past. When Iran struck Al-Asad air base in Iraq in January 2020, for example, reports quickly established a misperception that Iran purposely avoided killing American service members. It took time before analysts noted that Iran did not “aim to miss” U.S. service members. Over 100 U.S. service members suffered traumatic brain injuries, with 80 troops awarded Purple Hearts. It is a miracle that Americans did not die.

Q3: How did Israeli air defenses perform against Iran’s attack?

A3: This episode represents an outstanding success story for air and missile defense. Despite the over 300 ballistic missiles, drones, and cruise missiles launched, there appears to have been minimal damage to Israeli infrastructure and military assets, and the attack resulted in only one Israeli casualty .

It was also a joint effort. The coalition was led by the United States and featured the United Kingdom, France, and Jordan, in addition to Israel. Coordination took place at the Combined Air Operations Center at Al Udeid Air Base in Qatar, which helped to prevent any friendly fire incidents. Although Saudi Arabia has denied direct involvement, the kingdom at least allowed U.S. aircraft stationed in the country to engage Iranian air threats. Israel’s Arab neighbors also may have contributed intelligence and sensor assets to detect and track Iranian air threats, although the extent of this cooperation remains unclear. U.S. policymakers have long advocated for an integrated missile defense in the region, and this joint operation helps illustrate why.

In an era of missile warfare , missile defenses have proven their worth. This has been demonstrated repeatedly in Saudi Arabia against the Houthis, in Ukraine against Russia, and now in Israel against Iran. It was only a few years ago that analysts confidently claimed that defenses do not work . Yet in this operation, U.S. Central Command stated that it took down at least six ballistic missiles; the U.S. Navy employed SM-3 interceptors for the first time in combat, which were reportedly successful; and the Israel Defense Forces (IDF) of course employed its own air defenses . Air and missile defense works, saves lives, and reduces pressure on policymakers to respond immediately or excessively.

More will be revealed about the air and missile defense story in the coming weeks. An IDF spokesperson has claimed a 99 percent intercept rate. It is unclear if this figure includes Iranian missiles that failed at launch or in flight, or those that struck uninhabited areas. It is also unclear if Israel is identifying smaller surface-to-surface rockets as “ballistic missiles,” which fly farther and hit harder. In any case, even if the IDF eventually lowers this figure, coalition air and missile defenses clearly performed well in this operation.

Q4: What is known about Israel’s response?

A4: Most defense analysts correctly assessed that Israel would retaliate militarily. The question on everyone’s mind was the magnitude of the response. The Biden administration lobbied to minimize the strike to reduce further tit-for-tat attacks. If Israel’s attack was sufficiently limited, Iran may not respond, having dealt what it deems to be sufficient damage. That, at least, was the hope.

It increasingly appears that those hopes were actualized. Current reporting suggests Israel’s strike was limited and the IDF gave notice to U.S. policymakers before engaging Iran. The IRGC claims that its air defenses fended off the attack, which seems unlikely given Iranian capabilities but suggests that Iran will not respond.

Q5: What happens now?

A5: We’re back to a tenuous status quo. Iran has shown that attacks on diplomatic facilities—even those in Syria—will not be tolerated. Israel has shown that its air and missile defenses, when coordinated with the United States and regional partners, are extremely capable and that it will respond to Iranian attacks on Israeli territory. 

The Iran-Israel conflict also serves as a reminder that countries do not just stumble into war. Leaders climb onto the escalation ladder willingly and in turn generate dynamics that they cannot easily unmake. The question now is how the United States and others can unwind these dynamics for a more stable, peaceful security environment. Missile defense plays a critical role, but technology won’t save Israel from having to answer hard questions over its security strategy.

Looking forward, Israeli policymakers will face difficult trade-offs in managing their national security priorities. Hamas’s October 7 attacks inevitably pulled Israel into Gaza, but Israeli policymakers have chosen a maximalist approach that has pushed allies and partners away. These same relationships, particularly with the United States and Israel’s Arab neighbors, are especially important given their mutual aims in deterring and defeating Iranian aggression. Perhaps this week’s conflict—and the cooperation it prompted—may serve as a reminder of that common goal.
