Well it would depend on how accurate they are, if the text there is accurate about ship attack, these seem intended to hit the weaker armor around, or go into the funnel on ships. That would be more than enough even against MBTs.
no idea which is likely the reason why there not in game. They would be OP or really dumb depending on how there added at least Japan would get some good domestic ground attack options for once. (good because there is nothing else)
Nuclear Escalation anti-shipping F-2 experience

1 hour of gameplay to sink 1 corvette and losing 15k sl
The sea-skimming ASMs have been very disappointing in this mode, even the frigates intercept 4 out of 6. Kh-31ADs are much better.
The Kh-31D"s are some of the most busted missiles in the game performance wise, so it makes sense.
If Gaijin added the ASM-3, which is Ramjet powered like the Kh-31D, Japan would be muchhhhhh better at ASM duties.
Yep the Kuznesov HE-VT is good as well as the missile launcher destroyers, that’s the main point of creating a faster ASM (the 3A) but it’s not in-game yet… It would have been insanely good.
Japan is specialized in the defense of island and anti-ship duties, but Gaijin is making it impossible to show/use in-game because they add the JASDF ‘top’ armament too late (ASM-3A) or busted (ASM-1 and 2 where impossible to get a hit with until the very recent rework of anti-ship missiles… After everyone getting a comparable/better missile.
According to this, the GCS-1’s will be looking for anything source that’s +15C / +65C hotter than the surface which it’s located. (thanks @skultew1234 for clarification)




I got it from the old WT form before everything got wiped.
After digging through some more, I managed to find a different source that mentions something similar.
Also some other source I found about when it came about GCS-1
GCS-1
GCS-1精密誘導装置、20世紀末までに自衛隊に装備されていたものはこれくらいです。航空自衛隊では主として対艦攻撃が重視され、91式爆弾用誘導装置GCS-1が開発されました。これは艦船の赤外線、より端的にはエンジン排熱等を感知し誘導する爆弾です。北朝鮮ミサイル実験の際には、航空自衛隊の精密誘導爆弾として紹介される事もありましたが、対地攻撃を行うにはミサイル発射装置の排熱を感知する必要があり、近くに他の熱源、別の車両や炊事場などがあれば精密に誘導できない、対艦攻撃用です、が、対艦攻撃用の場合には確実に機関部を照準でき、且つ、爆弾本体を直撃させるため、ミサイルよりも貫徹力が大きい
Translation
This is about the extent of the GCS-1 precision guidance system that the Self-Defense Forces were equipped with by the end of the 20th century. The Japan Air Self-Defense Force mainly emphasized anti-ship attacks, and the GCS-1 guidance system for the Type 91 bomb was developed. This is a bomb that senses and guides the ship’s infrared rays, more specifically engine exhaust heat. During North Korea’s missile tests, it was sometimes introduced as a precision-guided bomb by the Air Self-Defense Force, but to carry out ground attacks, it is necessary to detect the exhaust heat from the missile launcher, and if there are other heat sources, vehicles, or kitchens nearby, precise guidance is impossible. It is intended for anti-ship attacks, but in the case of anti-ship attacks, it can reliably target the engine and directly hit the bomb itself. It has greater penetration than missiles.
Haha imagine cooking a good pizza on your bayside house and get nuked by a hungry heat-seeking 750kg bomb
+65C +/-15C seems to say it’s in the range of 50-80C over the surroundings. I don’t know exactly how hot a tank’s engine deck can get.
EDIT:
Is this part about the GCS being able to target this truck also real or just hypothetical?
That part was used as a example of their Mobile ballistic launcher as for example.
Something that there was info of to base an assumption off.
If it can track mobile ballistic missile launchers which produce this levels of heat/emission, a tank with a more higher rate of fuel consumption and emissions should be easier to track.
albeit as long it isn’t clustered among other similar emitting heatsources.
So the GCS-1 was actually tested against that truck and successfully tracked it?
I think this is a bit of a part A part B where it just needs to get close enough a missile launcher cant take any punishment so if it lands just close enough a small chunk of metal can break the missile. This is not a drone video of a launcher getting nuked its do the minimum to get maximum gain.
Talking about heat seeking bombs I hope we get stuff like the WW2 Ke-Go bombs

These would get a lot of use in Naval blasting ships and the like. Yes you would likely not get a kill but with engine room explosions you can do damage. You also might survive more as a plane.
It would be huge if they actually tested a real GCS against a real truck and got a good result out of it, could be used to further widespread knowledge of this bomb
If you think the Russians and Americans are quiet on there tests I find the Japanese are even more quiet. The language issue is not helping.
https://www.youtube.com/watch?v=rzObIRbhYOg can anyone identify the plethora of tank images shown in this video? because i have never seem a lot of these models or variants before especially the ka-chis
They aré not really quiet on the contrary they do one of the most extensive tests out there but dont like to share all info and when they do its hard to access, just find It under atla research page
Could add the ka-to to fill the ho-ris br hole?
not really would be lower BR
ka-to if added would be sort of like LG you can nuke everyone and anyone with a pistol can nuke you.
Funny enough Ho-Ri is in enlisted.
