/ Mitsubishi Ki-51
The Mitsubishi Ki-51 was a light bomber/dive bomber in service with the Imperial Japanese Army during World War II.
It first flew in mid-1939.
Initially deployed against Chinese forces, it proved to be too slow to hold up against the fighter aircraft of the other Allied powers.
However, it performed a useful ground-attack role in the China-Burma-India Theatre, notably from airfields too rough for many other aircraft.
As the war drew to a close, the Japanese began using them in kamikaze attacks.
Total production was around 2,385 units.
On the day Hiroshima was destroyed by an atomic bomb, a single Ki-51 was responsible for the last Japanese sinking of a US warship, sinking USS
with all hands.
