The ammo uses 断熱圧縮 (Adiabatic process) to detonate, it’s literally exchanging the pressure for heat to make a tiny explosion by its own sealant, the effect itself contains the word air because it usually happens by air containment in the chamber. So search before you use random examples to compare different things. M23 is similar in its construction.
Another fun fact. Initially, the air column fuse was very sensitive. They figured out tweaking the thickness of the outer layer can consistently add a delay & sensitiveness on the hitting surfaces. British Aerial 20mm APHE works on the similar principles.
Ki-44-ii literally climbs at 27mps on ground and 25mps at 2000~3000m, 19mps at 4000~6000m. That’s nearly the same as J2M. Ki-84 is below that. If you hit the enemy even for the slightest, they would die so the extra gun power of Ki-84 is only relevant in bomber interception. Ki-44’s own-weight wingloading is 140kg/m2 in game, Ki-84’s wingloading in game is at 135kg/m2. It’s basically the same. It turns in the almost same turn radius, but the higher power-to-weight ratio allows Ki-44 to turn at higher turn-rate.
Use in-game data instead of wiki’s empty weight for a reference, because the game is using gross weight - fuel to calculate the minimum weight.
I never talked about nerfing top tier Japan, I mentioned about adding the planes of the same designations with different engines. You seem forgetting of the topic’s original subject. We are talking about if the aircraft in this game reflects the performance of the reference aircraft. The engines usually mounted on Ki-84 and N1Ks is different in real life, even though the type is the same, the engine differed depending on the vehicle. Ki-84 ko would have either Homare 11 (1800hp max) or Homare 21 (1990hp) but Homare 21 is de-rated (certainly the most common case), so that it would have the exact same power envelope as Homare 11, which is at 1800hp max. So 2000hp Ki-84 nor N1K happened only at the development stage flight test. Also the flight test datas available are vehicles mounted with Homare 11, so their indicated speed in game is 40 to 50kmph faster than in real life. Even with Homare 21 it would be a rare case. The common knowledge knowaday is that the engine was likely outputting 1600~1800hp, 200hp less than the expected performance again. Because of the deteriorating lubrication oil and fuel quality. So it would be logical to have 640kph Ki-84 as another variant, maybe specifically Ki-84 ko. But if the armament swap could change the BR dynamically, we can have one Ki-84 (Homare 11) in normal tree and it would function as Ko, Otsu, Hei, by just the means of modifications.
Ki-44 by itself is undertiered, Ma-102 is installed on ki-44 after 1944 and they saw a wide service until the war’s end. So it would be logical if the stock ki-44 without access to ma-102 to be at 3.7, and with ma-102 it would be right at 4.3~4.7. Ki-44-ii is not increasing in its BR enough, it needs to go higher. Ki-84 ko with 200hp less would be a good 5.0~5.3 material. But it would be on par with Ki-44-ii, even with the better armaments.
Saying something like “Gaijin won’t change BR anyway even if it’s not right” is not constructive nor matching the topic. We are better off talking about where it should sit at instead of the current BR. First problem being Japanese planes overperforming, my solution is to add a weaker version of them and make the top tier Japan stay as it is. Second problem is them equipped with the final armament upgrade, post-1944 armament is a significant modification done to vehicle fielded in 1942. So the armament swap modification should be made as an option, and it should dynamically affect the BR. With the new BR, K/D and server-administrated results that might affect the BR should be on-par with renewed BR. Also, the scores should be administrated differently like a different vehicle so that it can be used for adjusting the BR of the same plane possible without human interaction after this system is applied. This can be done for other nations, Like on Me 109 (though the performance decrease by installing gunpods is fair trade, and 20-30mm conversion won’t change BR because of its limited ammo and velocity). M2 equipped aircraft should be able to use mid or even late war belts even if they are 1940 or 1941 plane, because they obviously would equip them late in the war, as long as they are not retired of the frontline service. So what about F4U-1 having Late war belts, at 0.3 higher BR. It would be quite logical.
