Autocannon by Anthony G. Williams and some other source state that Ho-203 cartridge was based on those used by Type 11 Infantry Gun. Of course a lighter HE shell was developed to improve velocity, but it wasn’t enough and Ho-204 used the same shell with larger propellant. In game Ho-204 appears to be using a 600g ground use HE, while it should have 475g HEI with 32g HE filler. Right now I’m not sure about the filler type.
TM 9-1985-5 Japanese Explosive Ordnance 2 also states Ho-203 and Ho-204 used the same shell. It also mentions that all 37mm AT-guns used the same Type 94 AP round, but unfortunately it doesn’t have anything about Type 1 AP round.
雑誌 航空ファン 1997 2 No.92 イラストレイテッド 日本陸軍機 “Bunrindo Number Catalog” lists an AP round for Ho-204 with 726g projectile weight and 1236g full weight and muzzle velocity just 525m/s. The projectile weight matches Type 1 APHE. CINCPAC Bulletin 85-45 Japanese Projectiles Vol 1 has Type 1 APHE.
Manual mention only 500kg
tbh it mention only one 250kg bomb but probably it could take more?
Is there any more source about 2 250kg bomb than book where it was mentioned? Because in manual only 1 250kg mentioned. And looking in the bomb racks looks like 2 250kg can’t be fitted because of sizes
I didn’t check this one properly when I made the report. It’s surprisingly detailed. To me it looks like the racks could be too close together to fit two 250kg bombs side by side.
I think 2x250kg is just a guess made by authors. If plane can carry 4x100kg, 1x500kg or even 1x800kg bomb, then why not 2x250kg? Well many planes could, but in Ki-102 case, it’s limited by the racks. Even from the photos and manual rack picture, I thought there would be two large bomb racks side by side, but apparently no.
Page 207 from manual. You can see how bomb #1 switch goes to two solenoids, while all the rest go to just one. It’s obviously meant for releasing 250kg, 500kg and 800kg bomb.
No way, a source that straight up says the 57mm shell containted 310g explosive?
I tried to convince Gaijin is was more but without a source they just left it as it is.
And even the 250g on the ground cannon HE is missing a huge junk of explosive since it has a giant detonator, which the Devs won’t acknowledge.
But to be fair the source you provided also only list 250g for the ground cannon HE.
