back to article Sweden rolls out invisible infrared tank

Engineers in Sweden have announced the development of a prototype tank which is covered in "pixels" that enable it to disappear from thermal images – or to disguise itself as something else. The "Adaptiv" system, funded by the Swedish Defence Materiel Administration (FMV), covers the test vehicle in hexagonal panels whose …

    Given that a tank is likely to be warmer than its surroundings (OK, maybe not if it was in a desert during the day), then. essentially, they're covering their tanks in lots of little hexagonal fridges?

      Fridges? Peltiers?!

      It's obvious that there is a net heat production for any type of cooling (and Peltiers are some of the least efficient), and on top of any engine heat.

      So either this also has a giant tank of liquid nitrogren or so, or it only works on a non-running tank and non-sunny days (as the heat would build up too)...

      T59's in the Thar desert

      I can confirm that tanks left in the desert all day get "very" hot.

      After using a T59 tank in the Thar desert, 54 degress C in the shade, all day it really was not advisable to climb onto the tank without gloves.

      As for going inside to fix some kit, it was not a very pleasant experience.

      TBH the thing that struck me most about the T59 was how small it was inside. I know the Chinese are usually quite small but I had to be very careful when in the gunners seat that my shoulder/right arm didnt get too close to the breech when firing.

      As to a commander getting in and buttoning up behind me, I am 6ft 6in, then to say the least it was "cosy" and you became very "intimately" acquainted, as did the driver's head to your crotch.

      I really do hope the modern ones are a lot bigger inside.

      The CV-90 actually is (rather) quiet and small(ish). This is not a full MBT but rather a light tank (~30 tons, a 40mm Bofors and tiny silouette). And diesel engines (unlike gas turbines) can be frightenly quiet, nothing like sneaking in the woods and stumbling into one of these which has been lurking, observing and ...waiting.

    Interesting picture

    Wandered out into the field and took a randomn photo of some grass and trees? Stealth is a 'relative' thing as you can't exactly make a 60 ton tank completely invisible and even a deaf person is going to 'feel' it coming at over 200 hundred yards away! Until they get rid of those gas turbine engines and drop the weight a little, that is never going away.

    Lewis must be slipping, he seems to be praising a BAE invention? Granted, not a British BAE one, but BAE all the same. Maybe he has needed to go and lie down after this article?!

    Now thermal reduction on a warship and disguising it as a fishing trawler is a great idea. Might just give those Type 45s a sporting chance against super sonic sea skimming missiles, assuming the Russkies did code it to have a smart warship identifier seeker rather than a 'kill anything it sees' one...

    don't need to be blind to miss it

    i think some commentards are missing the point. the modern tanks biggest enemy in "traditional" warfare is the attack helicopter. this system is designed so that an apache flying at night by thermal/ir will class it as a truck which can be multipurpose could even be civilian, maybe rules of engagement state no firing on anything but T-72's. its not some magic camo but it would have its uses.

    As for being blind try spotting a black/olive drab thing at night somewhere with no lighting i.e desert, steepes etc its hard to do in the uk because of all the light pollution but you'd be suprised how crap human vision can be. sure you'd here it but i have a feeling this thing is for spoofing aircraft that hunt on IR and not people on the ground.

    of course this assumes a type of warfare that's pretty much unlikely to happen anyone with an attack helicopter/tank fleet big enough to warrant this has too much to loose (economically etc, china's not going to attack you America ffs) by going into a big tank vs helicopter war and 3rd world nations using surplus soviet tanks wont be able to afford it and don't have the air capability anyway

        "....a painted canvas and wire frame...." The Jerries were reliant on the old Eyeball Mk1, aided by a bit of photo-recce. But modern thermal imagers and infra-red cameras can "see" through such contraptions. Same goes for the traditional camouflague netting. A much better solution is to make static decoys with heat sources that look both visually and thermally like a tank with it's engine idling. That ruse was very successfully used by the Serbs to keep NATO guessing in the former Yugoslavia. I presume the next step will be droid vehicles with thermally-enhanced visual signatures and fake armour to roll ahead of your real armour and draw the enemy's anti-tank fire, so the following tanks can then nail those AT assets.

    How do you store heat?

    Assuming your tank is hotter than its surroundings, how do you store heat to conceal its presence? Assuming that you can't (I don't think so) then what's the best way to get rid of the excess heat to conceal its true shape? Perhaps you could lazer* it away.

    1. peter 45

      Nail on head

      The heat has to go somewhere.

      Idea 1. IR cool one side (facing the enemy) and send heat to other side.

      idea 2. Switch on only for short periods, like when enemy detected (missile launch detected, laser targeting detected, ESM etc).

      Idea 3. Drag really hot radiator behind (like ESM systems on aircraft) to distract missile aiming system.

    And its small and hardly consumes any power, double coolness.

    Physical limits

    Presumably a tank is normally somewhat warmer than its surroundings since it has a dirty great engine in there to power it. Hence the use of thermal imaging to spot it. So to cool its exterior you need to pump heat into the interior or, equivalently, prevent the interior heat from escaping against the natural thermal gradient. That includes all the heat that'd normally come from the engine cooling system and exhaust which I imagine must run to quite a large number of kilowatts.

    Seems to me that's going to make it pretty hot inside - and with no heat escaping, the temperature will just go on rising indefinitely. Well, until something melts anyway.

    I worked on thermal imagers in the early 80's and you could tell by looking at the tracks on the ground which ones had been made by a tank going past several hours before, as opposed to days, and which direction it went. The temperature differential that could be seen was tiny.

    I suspect they have got better since then.

      Since everything is running to missiles and Mogadishu "technicals," I don't see the point in disguising machinery that's on its way out. The current threat isn't direct, it's from IEDs and plain old terrorizing the populace.

  48. Anonymous Coward


    I'm amazed at the level of misunderstanding in the comments. In a tank to tank conflict seeing the tank accurately is key because sight is still used for targeting. To counter that most tanks have smoke generators. And to counter that most tanks have IR sights so you can still see (albeit degraded slightly) when in a big smoke cloud. If you can throw smoke and then IR cloak, it could reduce the range that the enemy can engage to less than the range at which you can engage. Queue up a duck shoot. You aren't trying to sneak a tank up on someone, you are just trying to make targeting it very hard. It is the same thing with stealth planes. You don't mind if someone sees you, or even to a certain extent if they hear you (although stealth planes are designed to be quieter than non-stealth versions). What matters is whether the missile shot at you can get a lock. Which crucially means it sees you on either radar or infra-red.

    For those who point out that these days more tank kills are done from aircraft, please explain how the aircraft get their kills. It is actually through the same means, either visual sightings or IR sighting primarily. Again, if the tank blows smoke and cloaks in IR it could significantly reduce the accuracy of aircraft. You will still lose tanks, but a lot less than before when targeting was accurate.
