Hi!
I have the idea - maby some modder could
increase the number of variants for this aircraft armament, (like adding new 20mm and 12.7mm guns):
Ki-45 KAIa Toryu: Two-seat fighter Type 2 of Army (Mark A) initial model of series, one 20mm Ho-3 and two Ho-103 12.7mm in the nose and a flexible 7.92mm in the back position.
Ki-45 KAIb retrofit version based on the KAIa, two Ho-103 12.7mm in the nose and 20mm belly cannon replaced by a 37mm type 94 field gun and a flexible 7.92mm in the back position.
Ki-45 HEI the 20 mm cannon, and an automatic 37 mm (1.46 in) gun in the nose and a flexible 7.92mm in the back position.
"The first production type (Ko) was armed with two 12.7 mm (.50 in) Ho-103 machine gun in the nose, a single Type 97 20 mm cannon in the belly offset to the right, and a trainable 7.92 mm (.312 in) machine gun in the rear cabin, and this was followed with the Otsu with the lower 20 mm cannon replaced by a 37 mm (1.46 in) type 94 tank gun, to counter B-17 Flying Fortress bombers. While the firepower was devastating, manual reloading meant that only two rounds could be fired per minute. The next type (Hei) restored the 20 mm cannon, and this time placed an automatic 37 mm (1.46 in) gun in the nose."
Cheers!
