N80 Radar Cruise Control issues

Recommended Posts

I have 2021 N80 SR5 Hilux, when engaging radar cruise control it seems to work fine for a certain time. Sometimes 10mins, 20mins or even an hour then for no apparent reason it disengages and starts beeping and braking and the distance from the vehicle in front on the dash flashes orange/red, even when there is no car in front of me. To get it to work again I need to turn it off and on again to get it to work. This happened when I first got the car with no bull bar or led lightbar installed and has happened after bullbar and lightbar install. I spoke to Toyota at my first service and explained everything and they told me it is due to the lightbar, so I asked them why did it do it before the lightbar and bullbar install. They couldn’t answer that. Hope you guys can help. Cheers Dean

This may not be helpful, but is there anything obstructing the Toyota badge on the front grille? The new Hilux's cant have anything obstructing the badge as it messes with the TSS system. This includes some lightbars/spotlights/UHF aerials etc.

2021 Hilux (GUN126R) SR seat and radar cruise control

If you have the standard size tyres you’ll probably find your speedo is wrong anyway. If it says 110 you are probably actually doing 101 or so. All new cars in Australia have been like this for near to 15 years now.

You can still look at the dial speedo yes, but it's not as accurate and I much prefer to know the digital value. Does anyone know how to prevent the radar cruise control icon from overriding the digital speed display when an alarm comes on? I'm happy to never see the radar cruise icon (even when it has just detected the car in front) because it doesn't tell you anything anyway. 3) When the radar cruise control is on and it comes up on a car that is slowing down faster than the engine braking can slow my car, the hilux automatically applies the brakes....works very well. With my last car it used to apply the brakes for normal cruise control if it overshot it by about 3 km/hr (regardless of whether a car was in front or not), and that was brilliant because you could be assured at all times that you would never get a speeding fine. The Hilux, when cresting a hill and there is no car in front can overshoot the speed by well over 7-10 km/hr and I "think" it does apply some brake when it really gets out of control (>10km/hr over setpoint). Does anyone know if the setpoint for radar cruise control can be set to apply the brakes when it overshoots by xx km/hr (preferably 3km/hr overshoot)? Note: the last car didn't wear out the brakes due to this feature, and remember that I am now having to apply the brakes anyway to control the car (but kicking out the cruise function) so the times the brakes come on will be the same. I can't see any functions in the user manual or scrolling through the MFD options...there is something in there that you can set it to "warn" you at 1, 3 or 5 kms over, but all that does is start the beeping when it's gone over...it doesn't start applying the brakes etc. Cheers, Tony

Adaptive cruise control supplements conventional cruise control with an active vehicle-to-vehicle distance control feature. Designed for use on freeways and express ways, in vehicle-to-vehicle distance control mode, your car automatically accelerates or decelerates in order to maintain a preset following distance from the vehicle traveling directly ahead of you.

To activate the system, press the "ON/OFF" button at the end of the stalk on the lower end of the right side of the steering wheel. The radar-ready indicator will appear in the Multi Information Display.

Accelerate or decelerate to your intended speed, then press the stalk down to set it. If you want to go faster, push the stalk upward and hold until you've reached the desired speed and then release it. Or, if you want to slow down, push the stalk down and hold as you decelerate, then release it once you've reached the desired speed.

To cancel cruise control, tap the brakes, pull the stalk towards you or turn the system off with the ON/OFF button.

Adaptive Cruise Control was designed to maintain the preset distance between your car and the car driving in the same lane directly ahead of you.

When it’s active, it automatically adjusts for changes in the speed of the vehicle traveling directly ahead of you in order to maintain the vehicle-to-vehicle distance you set.

In the event that you would like to change the preset distance between vehicles, you can do so by using the radar range button located on the lower right side of the steering wheel. Simply press the button repeatedly to cycle through the ranges available. You'll find them displayed on the Multi Information Display. And finally, you can disable the distance holding feature by pushing the cruise control stalk away and holding it until the indicator disappears and the conventional cruise control indicator lights up.

2023 Toyota Hilux SR5 Cruiser | Car Review

The Hilux SR5 Cruiser was announced last year and promised a wider, taller Hilux with improved off-road capability, plus a more stable and comfortable driving experience on the open road. I drove it for a week to see how these claims stacked up.

Having recently moved to a rural property I have joined the ute life with a 30 year-old Ford Courier. When Toyota offered Drivelife the latest Hilux SR5 Cruiser I was keen to see how much progress had been made compared to my rather tired example.

SUV Comparison Chart

First Impressions Of The 2023 Toyota Hilux SR5 Cruiser

The new SR5 Cruiser certainly stands out – it’s tall, and that 120mm wider track, with matching fat plastic arches give it a real road presence. The huge black grille with its chrome inserts and the slightly frowny LED headlights give it an imposing face, and the fog lights have been integrated nicely into the new arches.

Apart from being a little taller, the side profile looks just like the previous SR5, with “SR5 CRUISER” and 4X4 graphics. It’s a good-looking overall package, with privacy glass on the rear windows and 18” alloy wheels. One thing that always niggles me as a design choice is the placing of the rectangular fuel filler door, so that they had to make a notch in the plastic arch to accommodate it. It just bothers me every time I see it.

The rear looks good with the traditional TOYOTA lettering on the tailgate, B-shaped tail lights and an integrated step in the rear bumper.

What’s The Interior Like In The 2023 Toyota Hilux SR5 Cruiser?

It’s quite a step up into the SR5 Cruiser, but there are side steps and grab handles in the A-pillars to help you get in more easily. Some of my passengers did complain a bit about having to climb into the vehicle. Once you’re in it’s very car-like with perforated leather, heated seats and a leather-clad steering wheel. The seats are comfortable and have enough side bolster support for everyday driving. The dash is solid-feeling with a straightforward design, integrating an 8” touch screen which will be familiar to anyone who has sat in a Toyota from the last five years. It has physical knobs and buttons, which we very much appreciate here at DriveLife.

The infotainment screen is connected to a 9-Speaker JBL Premium Audio system which gives a good, clear sound. There’s not a lot of bass even after tweaking the settings, but it’s well-balanced. Something we commented on with the previous model is still an issue with this one. The two speakers in the corners of the dash have a silver surround which reflects on the windscreen, and it catches your eye all the time as you’re driving.

Below the screen are the dual-zone aircon controls and a couple of power and USB sockets. The heated seat controls are lower down and are a bit odd, in that the top one controls the left seat and the bottom one the right, almost as though they are rotated 90 degrees; it’s not intuitive, especially when finding them on a dark morning.

There are two deep cup holders, I guess ute drivers like a large coffee as a medium cup gets a bit lost in there. There are also pop-out cupholders on the outsides of the dash which are less deep. There’s a manual handbrake lever, and a large centre cubby with a 220-volt socket inside for charging your tools.

The dash is the traditional two-dial layout with rev counter and speedo plus a centre screen for digital speedo, trip computer, off-road displays (such as wheel position), etc. Everything is clear and well laid-out and looks great at night with white and blue backlighting to go along with the blue ambient lighting.

The steering wheel controls are logical and easy to use. Cruise control is set via a third stalk which rotates with the wheel. Not my favourite way of doing it, but it works fine.

The three rear seats have enough leg room for an adult to fit, plus the 60/40 split base lifts up to reveal under-seat storage. There are handy hooks on the back of the two front seats, good for your takeaway bag to stop it falling over.

Out back there’s a plastic-lined tray which will do all the things you might want to do with a ute. There’s no damping on the tailgate, it’s heavy, and if you’re not ready for it, it’ll drop open with a clunk. This is standard for most utes, but I wish manufacturers would put some sort of damper on it to make it a bit safer. 

What’s The 2023 Toyota Hilux SR5 Cruiser Like To Drive?

After driving most other cars including a lot of SUVs, the Hilux feels huge. Tall and wide, it gives a commanding view over other road users. Not so big that it doesn’t fit in car parks, but some will be a tight squeeze.

This new version is 120mm wider than the previous SR5 Cruiser, and 15mm taller. They’ve replaced the rear drum brakes with ventilated discs, and upgraded the front discs to 17-inch ventilated. Toyota say the suspension has been tweaked to give a better ride and handling, as well as the addition of a rear stabiliser bar. They say this means improved steering feel when cornering and changing lanes. All of these tweaks have a weight cost – the kerb weight is up 80-105kg depending on options. Quoted fuel consumption is up from 7.9 to 9.5 litres per 100km despite the same engine power and torque from the 2.8-litre 4-cylinder turbo diesel unit. There’s a 6-speed auto transmission with selectable four-wheel drive, and ther rear diff is an automated limited-slip unit with a manually engaged locking system for off-roading.

Often with utes and larger vehicles, I find that the high driving position reduces the impression of speed when you’re driving, and in a 50 limit area it can feel like you’re barely moving. The SR5 Cruiser is no exception, it’s really easy to drift up over the speed limit, and that’s where radar cruise is a really great feature to have. You can set it and let the car control your speed easily, and smart cruise means you can trust it to slow down where needed. But there’s a problem in the Hilux, go under 30kph and there’s a beep, and the cruise control turns off. This makes it pretty useless in rush hour traffic. On the open road it’s much better and works very well, though it’s over-cautious and slows down more than I would like on corners.

There’s traffic sign recognition and it works really well, showing the current speed on the screen and turning the icon red when you exceed that limit. Like all of these systems it’s not a hundred percent accurate, so you have to be alert.

Toyota have added more safety features to the SR5 Cruiser, including rear-cross traffic alert and blind spot monitoring, both of which are great. The one that I didn’t enjoy was Toyota’s lane departure warning system. It was turned off when I picked up the SR5 Cruiser, so I turned it on and it took me a little while to place when it was intervening as it is quite subtle, but annoying too. Sometimes it’ll beep when going too close to a line, other times it will intervene by pulling back the throttle just slightly. It feels like when a big gust of wind hits the car, or when one wheel goes through a puddle, and you feel that drag. It’s odd, and I really don’t like it. I switched it back off and left it off.

There’s a 360-degree camera system on the SR5 Cruiser which can be set to automatically come on when needed, in conjunction with the parking sensors. It works well but the resolution isn’t up to the standard of the European manufacturers so it’s more a general guide than a precision tool. Also, the beep of the parking sensors is really piercing!

So what’s the SR5 Cruiser like to drive? Mostly good. There’s ample power, and loads of torque. It feels like towing a boat wouldn’t trouble it one bit. Acceleration is effortless and it’s no slouch. The handing is excellent, it feels firm and planted on corners, and will easily cope with anything a New Zealand State Highway can throw at it. Stability and control are very good and those new brakes work very well.

Upon first impression it laughs in the face of potholes. But drive over a less-than-perfect road surface at 50kph and you realise that the secondary ride quality is jittery and unsettled. When you go over bumps or imperfections in the surface it does a little shimmy as the rear wheels make contact. I picked up my wife in the SR5 Cruiser one day and 30 seconds after we set off she said “Is there something wrong with this car?” It can make your lower body jiggle in an unpleasant way, similar to a sports car with hard suspension. It would be enough to put me off buying one, and I see that John said similar things about the ride in the previous model in his review .

I spoke to a work colleague who used to daily drive a Hilux and he said whenever we went on a road trip he would put two scoops of firewood in the back, then the ride was excellent. That’s all well and good, but in a very unscientific survey that I did over the week I had the Hilux, maybe 5% of utes that I saw had anything in the back. And I live in New Plymouth where there are a lot of utes.

What about off-road, you ask? I wasn’t able to fully test the off-roading abilities of the Hilux but I did drive up a very slippery, wet farm track, and I can tell you that the low-ratio mode got me out of a tricky spot and saved the grass from being sprayed all over a curious horse in the next paddock.

Finally, fuel consumption.On a combination of town and highway driving I averaged 9.3l/100km which is less than the advertised figure of 9.5l/100km.

Sudden unexpected acceleration when depressing Resume/+ button

• Add to quote

Has anyone else had sudden unexpected acceleration when using the Radar Cruise Control and Lane Keep Assist and pressing the Resume/+ button on the steering wheel? It happened to us today, we were cruising down the highway and my husband pressed the Resume/+ button. The R4P speed up (as expected) and only stopped accelerating when he hit the brakes (not expected). Bug or feature? TIA.  

Assuming the cruise was set at higher than your current speed, why is acceleration unexpected? Or are you saying that it didn’t stop speeding up once you reached your set speed?  

Sorry for not being clearer-it was the latter. The Cruise Control was set to around 65, when he hit Resume/+, it was still accelerating to above 80 MPH when he hit the brakes. It was NOT set to 80 MPH.  

Are you sure? I don’t think the actual set cruise speed was at 65MPH. The set cruise speed is displayed. I think you may have set the speed at much higher speed and not realized it.  

It will keep accelerating up to the set speed as soon as you press resume. Sent from my SM-N950F using Tapatalk  

Thank you for your reply. The speed was set to a round 65MPH. When he 8-Mbriefly pressed Resume, it started speeding up and did not stop accelerating at around 80MPH when he hit the brakes. This was unexpected. In other Toyotas we've owned, a single press of the Resume button results in a 1-2 MPH speed increase. If you hold the button down, then the vehicles would continue to accelerate. But they would not continue to accelerate indefinitely if you just pressed and released the button quickly.  

That sounds worrying. Must be a fault. Have used ACC a lot with no problems whatsoever. Constantly pausing and resuming. Never accelerated beyond the setting. Do you have the speed limit recognition engaged in the setting as I wonder if it had read or misread a high speed limit and hitting resume skipped the manual speed setting and went to the speed limit it had read? I disabled all that (DRCC or something) as soon as I got the car. Too many temporary speed limits on our smart motorways in UK. Sent from my SM-N950F using Tapatalk  

Reproduce this glitch for the dealer technician and let Toyota fix it or replace your dangerously flawed R4Prime. If you can’t reproduce it, could it have been an inadvertent foot on the gas pedal. You can still accelerate past the ACC set speed by pressing the gas pedal.  

Yeah, that is definitely not normal behavior, and I use ACC on a weekly basis. Agreed that if you are able to reproduce the issue (in a SAFE location!) and show the mechanic, I have no doubt that Toyota will make it right, since that’s a serious safety hazard. But yeah… could also be foot on the accelerator!  

I noticed it when I put on the turn signal to pass when going slow behind someone.  

Do you mean that the Adaptive Cruise Control had reduced your speed when you were behind someone going slower than your speed setpoint, but when you turned on your turn signal to pass the car started accelerating right away? When I tried that the turn signal suppressed the Lane Tracing Assist, but the car didn't start accelerating until I had moved into the adjacent lane which was clear ahead.  

If you're sure that the RES+ button was not being held down, then one possibility could be a failure of the switch. Even though you weren't pushing on it, I wonder if it might have gotten stuck somehow. I'm not sure if the diagnostics screen lets you test all buttons, but I'll give it a try tomorrow. EDIT: I tried the diagnostics screen, but the only buttons that it will check are the ones on the Infotainment screen and the steering wheel buttons for making changes to the infotainment system (MODE, track, volume, etc.).  

What is the diagnostics screen that you mentioned?  

I believe that the OP may have a serious defect. Can he re-reproduce the problem? If so, then take it to the dealer. My Rav will start to accelerate as soon as I turn on the signal light. It isn't rapid, but it is there. I don't have an issue with it.  

OP should take it to the dealer so they can look at the logs. Could it be a glitch? Maybe. Could OP have pressed Resume+/Accelerate while behind a slower vehicle, only to be shocked that the R4P was now accelerating beyond the "initial" 65MPH set point? Possible. The logs would show all of this.  

I have a 2018 Rav4 and have never had this problem. Of course the ‘18 is only TSS 1.0, but dynamic radar cruise control has never done that for me. As @old timer mentioned, the only small acceleration that would be normal is when you signal with cruise on (designed for passing cars).  

Thanks to all for your thoughtful responses. I've contacted Toyota Corporate and our dealer. If I learn anything interesting I'll report back.  

The reason why I said this may be a user error because I have done it. You have to maintain certain distance between your car and the car ahead of you when using radar cruise control. Your husband may have pressed “+” without realizing he was increasing the cruise speed limit. Once the car front of you is cleared or there is enough distance then your RAV4 will accelerate until either cruise speed is achieved or you are limited by the safe distance. The radar controlled cruise control has been in use for a long time. I really doubt it was your RAV4 exceeding the set speed. Be safe out there.  

My husband was able to reproduce the problem, without changing lanes. His foot was not on the gas pedal either time. We may try again today, we have a few short trips to do. Thanks again-this forum and its participants are really positive, great and helpful!

The second time, he had cruise control set to about 70. The nearest car in front of us was quite a ways off. He briefly pressed and released Resume/+ and the car started accelerating pretty quickly. When it got to 80 MPH he hit the brakes and it stopped accelerating.  

I believe you! How did he confirm the cruise speed was set to 70mph? The cruise speed limit is displayed on your MID. Can you take a screenshot that shows the set cruise speed? Thanks  

I can try. It was displayed on the MID as I recall. I'll double check today and see if I can take a screenshot. Of course that means he gets to drive it...🤔🙀  

I've experienced something like this before. It parallels some of the perspectives people have already shared. Basically I had cruise control set to let's say 65 MPH and my following distance was at 3 bars (the most conservative setting) so the car in front of mine triggered my Prime to slow down to let's say its speed of 60 MPH. I wasn't yet used to the number of bars so I pressed the Resume + button five times (plus five MPH, meaning cruise control was now set at 70 MPH), but I of course didn't actually speed up because I was still "tethered" to the 60 MPH car in front of me. When it moved to the right lane my Prime accelerated aggressively because it was going 10 MPH under the 70 MPH cruise control setting. Fix? I now typically use a one-bar following distance vs two or three bars depending on driving conditions, and I've learned to pay attention to my HUD regarding current speed vs what cruise control is set to - I try to keep the MPH difference no greater than 5 MPH so my Prime doesn't think it needs to "floor it" to quickly catch up to my cruise control speed setting.

need video Let him drive, you record. Make sure the cruise mph is shown. It sounds like the + button is stuck or acting that way - but is the mph of the cruise also increasing by the corresponding amount? Or does it go from 70 to 71, while the car increases to 80?  

^You have a dangerous Unicorn R4P that needs to be tamed by Toyota. Take it in for service and fix under warranty … and let us know how it goes.🦄🚚  

Just dropped it off at the dealer for the day. We’ll see what they have to say.  

Dealer reports nothing wrong. I have a theory...but I think at this point, we'll keep an eye on it and drive cautiously with ACC on. Thanks again to all for your help in this adventure.

Could it be a sticky RES button that doesn’t always “unpress” itself after you press it? Not sure, just an idea.  

I was not able to replicate the problem today. I didn't get a chance to take any pictures of the MID-I did the driving today and was alone in the car mostly-but I used ACC and LKA a couple of times and it all worked fine. My theories are: 1. Sticky "Resume/+" button. 2. The husband hit "Resume/+" button repeatedly when the R4P was going under the set ACC speed and then when the car sped up again after the car in front of us was far enough away, or he changed lanes and no one was in front of us, it sped up to the limit that he didn't realize he set by repeatedly pressing the "Resume/+" button. He denies this theory. 3. Gremlins.

@PrimeRib next time you with hubby and he is driving, look closely at how he is pushing that resume button. I suspect he is doing without realization your number 2 point. When you are driving you may be more careful with button pushing, hence cannot replicate it.  

Remember to locate/look at the SET SPEED on display above steering wheel, to make sure it is not maxed out and ready to Rev-up when it sees empty lane.  

Got it, thanks.

Russian IADS Redux Part-7: The Effectors

In the next part of our series on Russia’s strategic integrated air defence system, we look at the kinetic ground-based air defence systems it deploys.

In part-6 of our series on Russia’s strategic Integrated Air Defence System (IADS) we examined the command and control architecture it depends upon. The IADS’ role is ultimately to provide a response to air threats approaching or entering Russian airspace. In Russian air defence doctrine this response is provided using kinetic and/or electronic effects.

The kinetic side of the IADS depends on the Russian Aerospace Force’s (RASF’s) fighters and Surface-to-Air Missile (SAM) systems. Sources have shared with Armada that both the fighter and SAM force would be deployed in wartime to protect key Russian strategic targets. Typically, these could include politico-military targets like the Kremlin, the seat of the Russian government in Moscow. Other potential strategic targets include hardened facilities believed to be earmarked for use by the Russian leadership in wartime. One of these facilities is thought to be located at Mount Yamantau, southwest Russia. A back-up facility may exist at Mount Kosvinsky Kaman, western Russia. Russia’s industrial city of Elektrostal, on the eastern outskirts of Moscow, was one of the first locations where the RASF deployed its S-400 (NATO reporting name SA-21 Growler) high-altitude, long-range SAM systems in 2010.

The SAM Systems

Moscow itself is ring-fenced by the RASF’s 53T6 (ABM-3 Gazelle) anti-ballistic missile system. The 53T6 employs SAMs equipped with a ten kiloton (one kiloton is equal to 1,000 tonnes of conventional explosive) nuclear warhead. These missiles would detonate at altitude in proximity to incoming salvos of ballistic missile warheads or formations of hostile aircraft. The logic is that this ‘shotgun’ approach will vaporise, or at least badly damage, these targets.

The S-400 is the mainstay of the RASF SAM force. A typical S-400 battalion includes two batteries. A battery comprises between eight and twelve individual launch vehicles, each equipped with four missile tubes. Thus, an S-400 regiment could have between 56 and 84 individual missiles ready to launch if fully loaded.  Each battery has a command post, a 91N6 (Big Bird) S-band (2.3 gigahertz/GHz to 2.5GHz/2.7GHz to 3.7GHz) 324 nautical mile/nm (600 kilometre/km) range surveillance and tracking radar. The 91N6 is joined by a 96L6E (Cheese Board) C-band (5.25GHz to 5.925GHz) early warning and target acquisition radar. This radar has a range of up to 162nm (300km). A plethora of SAMs can be launched by the S-400 with an array of engagement ranges from 21.6nm (40km) using the active radar homing 9M96E missile. Engagement ranges can reach up to 216nm (400km) using the 40N6E missile which has a reported engagement altitude of 98,425 feet/ft (30,000 metres/m).

Legacy systems used by the RASF include the S-300PS (SA-10B Grumble-B) and S-300PM (SA-10D/E Grumble) which have subtle differences. An S-300PS battery has three Maz-543 launch vehicles each with four launch tubes. The battery is also equipped with a single 5N63S (Flap Lid-B) X-band (8.5GHz to 10.68GHz) fire control radar. An S-300PM battery has a single 36N6E (Flap Lid) X-band/Ku-band (13.4GHz to 14GHz/15.7GHz to 17.7GHz) fire control radar with a 162nm (300km) range. Joining the 36N6E is a 76N6 (Clam Shell) X-band (8.5GHz to 10.68GHz) search and track radar with a 70nm (120km) range. The rest of the battery is comprised of up to eight Kraz-260 launch vehicles each with four tubes. Both the S-300PS/PM are thought to deploy 48N6/E SAMs which have a reported 81nm (150km) range. The S-300PS/PM’s 5V55R missile has an engagement range of up to 48.6nm (90km).

Sources have shared with Armada that RASF SAM batteries are not routinely deployed but may deploy from time-to-time to support exercises or training. The batteries would only be deployed in anger to protect key strategic targets like those discussed above. The sources continued that the task of the SAM units is to provide a protective ‘bubble’ above these targets. Air defence coverage up to 54 nautical miles/nm (100 kilometres/km) altitude and a range radius of 189nm (350km) around the target would be provided. The SAM units would work to attrit any incoming air attack as much as possible. Russian air defence doctrine focuses on safeguarding as many strategic targets as possible in anticipation of an eventual counterattack.

One crucial part of the RASF’s SAM force is its 96K6 Pantsir-S1 (SA-22 Greyhound) combined medium-range SAM and anti-aircraft artillery systems. 96K6 units would deploy with S-300 and S-400 batteries. Their role would be to destroy air-launched weapons like anti-radiation missiles or attack helicopters engaging the batteries Armada’s sources added.

Over the longer term, the RASF is looking to introduce new SAM systems to enhance the strategic IADS in the form of the S-350E and S-500 Prometey long-range, high-altitude SAM systems. The S-350E is mooted as a replacement for the RASF’s S-300PS/PM batteries. Open sources state that a S-350E battery has one 50N6A X-band ground-based air surveillance radar with a range of 215nm (400km). The 50N6A is joined by a single 50K6A mobile command post and up to eight 50P6 launch vehicles. Each launch vehicle can fire 9M96/E or 9M100 SAMs with engagement ranges and altitudes of up to 65nm (120km) and 98,000ft (30,000m) respectively. It was reported in January 2020 that the first S-350E battery had entered service, although a developmental system may have been deployed to support Russia’s military presence in Syria. The VKS could receive twelve S-350E batteries by 2027.

The S-500 is mooted to have a longer engagement range than the S-350E. The S-500 ensemble includes a 91N6A(M) air surveillance and battle management radar. This radar is an enhanced version of the 91N6A radar accompanying the S-400. The S-500’s 96L6TSP target acquisition radar is an enhanced variant of the S-400’s 96L6E. These two systems are accompanied by the 76T6 multimode fire control radar, itself thought to be a derivative of the 92N6. Also forming part of the S-500 ensemble is the 77T6 anti-ballistic missile engagement radar the capabilities of which remain largely unknown in the public domain.

Open sources say that missiles equipping the S-500 could hit targets at ranges of up to 270nm (500km). Russian sources have claimed that the S-500 could engage targets at up to 656,168ft (200,000m) altitude. Russian media, seldom the most reliable source, claim that the first S-500 regiment went on combat duty in October 2021.

The long-term prognosis for the S-500 and S-350E systems remains uncertain. As documented by the Royal United Services Institute, a London-based thinktank, the Russian defence industry is dependent on clandestinely-sourced Western microelectronics for sophisticated weapons systems. Will Western efforts to clamp down on Russia’s access to such technology have an impact on the fortunes of the S-350E and S-500?

Stay tuned for more analysis on Russia’s strategic air defence capabilities in the next instalment of our Russian IADS Redux series.
