History

Intended as an anti-bomber weapon, the Ho-301 is an unusual cannon that uses caseless ammunition. The rounds use a aluminum cup to carry the projectile along with a silk bag with the propellant, and the primer. When the primer is struck, the bag of propellant is ignited but the projectile is not launched from the chamber until the pressure causes the cup to burst through the exhaust holes on the base. The Ho-301, used on the Ki-44 suffers from a low velocity and is only effective against bombers close range.

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
