There has been some discussion in the forum about conducting tests to alter the fragmentation pattern of APHE shells.
Towards the end of WWII, Japan produced a mysterious ammunition called the Type 4 AP shot, which lacked explosive filler and fuzes, for various calibers of guns. The development history of this ammunition has been partially revealed. I am introducing this in preparation for the possibility that Snail might nerf APHE shells and buff AP shots.
According to the testimony of Colonel Seiichi Imai, who was affiliated with the 1st Army Technical Research Institute that studied anti-tank guns and armor-piercing shells, they developed solid armor-piercing shells to improve penetration power. Originally, the Japanese Army used solid armor-piercing rounds without explosives for calibers ranging from 7.7 mm to 20 mm due to their small size, but this was later adopted for larger caliber guns. When an APHE shell hits armor thicker than its caliber at a very high strike velocity, the shell body can be destroyed, reducing penetration power. However, with solid AP shots, the projectile body remains intact and can penetrate. Nevertheless, it goes without saying that APHE shells are superior to AP shots in terms of damage effect inside the tank.

Thank you for sharing it!
Searching through old forum posts found the Aizenns (if i don’t mistake) about Type 4 AP shell and according those descriptions it had space inside filled with sand and that Type 4 AP was filled with sand because of poor economic situation. But the shell with space inside has the same problems with weaker structure as APHE. And according description from your book it should be full metal.
So as a result, is it full metal AP shell or AP with sand inside?
Considering the development history, it is likely a full metal solid shot with a stronger structure than the Type 1 APHE shell. It seems to be a misunderstanding that the Type 4 AP shot was a cheap shell filled with sand instead of explosives due to a shortage of raw materials caused by the bombing. The shells filled with sand are substitute shells used for training.
Interesting.
In game Type 4 Kou shell weight is 6.75kg and in calculating via Gaijin method we get 154mm of penetration. I am not sure about how truly the weight of Type 4 AP is. But it looks sadly
It seems there are shells such as the Type 4 AP shot as you mentioned, but also the Toku Kou, Experimental 47 mm Type 1 Tungsten APHEBC, and Nickel Chromium Steel Otsu AP shel
the Ho-ri has insanely good mobility with very tricky armor and a great gun with good chunk of explosive filler and good firerate i’ve had my fun in it at 7.3 but yeah i dont think its 7.3 material maybe 7.0 at most
It has basically same role as Jagtiger. Tho Jagtiger has way better gun, armour and better max speed. I dont really see how superheavy tankdestroyer have as huge advantage that its engine has more power/ accelerates better because when you get caught flanking with both jagtiger or ho-ri then you are dead. It should be no less than 6.7 even tho its still worse than Jagtiger in all that matters for its job and ho-ri prototype should be 6.3. If 7.0 then jagtier and ferdinand should be 7.0 too.
as for max speed its subjective i have the jagdtiger and altough the gun is great i’d rather take the decently good pen of the 105 from the ho ri and the fire (ho ri production)
Japanese laws for these kinds of vehicles being transported on the road requires the commander to be turned out to maintain a view around the vehicle. Since the turret is unmanned, there is just a small space for the commander to stand during transport to comply with the laws.
Ho-Ri production is FAST for how much armor you’re bringing, definitely better than the Jagdtiger. And has a better reload, which makes you less vulnerable.
I don’t agree with ,“is worse than Jagtier in every way”. I would much rather drive a faster, more mobile Ho-Ri than a slow, super heavy, Jag…Just so much better to drive around with regardless if it has a bit less armor and lower pen. So Ho-Ri at 7.3 is fine and still manageable though 7.0 would be the best fit for it.
yeah my favorite thing about the ho ri its the amazing speed with decent-good armor and incredible survivability together with a very nice gun that has so much explosive filler u are assured to overpressure somebody’s crew even if no spall hits em
