This is a new twin-engine bomber developed by the IJA, the Ki-67 Type 4 Heavy Bomber "Hiryuu".
It can't carry many bombs, but is light and maneuverable. It can also carry torpedoes on external hardpoints.
It was deployed as a trump card with heavier armament and more equipment than other Japanese bombers. It fought during the harshest period of the war in the IJA bombing corps.
