Nakajima B5N in Days of Infamy Edit
The Nakajima B5N1, which was a high-level bomber, and the B5N2, which was a torpedo plane, were used by the invading Japanese against the US forces at Hawaii, and later against the US fleet during their first attempt to retake Hawaii. Although obsolete, they performed admirably.
After the battle, the Navy abandoned the B5N1 for the B5N2 model, for fear that switching between the different armaments the B5N1 used could leave their carriers dangerously vulnerable during an attack. However, when the Americans returned in 1943, the torpedo planes were easy prey for the new American fighters, and all of them were destroyed as they attacked their targets or attempted to return to their carriers.
