Tachikawa Ki.74 ("Patsy"/"Pat")

The Ki-74 was first conceived in 1939 as a long-range reconnaissance aircraft to operate from Manchurian bases. Its development was shelved when further research was needed to design its pressurized cabin. Late in 1941 the project was revived as a long-range high-altitude bomber-reconnaissance  aircraft capable of bombing the United States mainland. The war ended before the aircraft could be deployed in sufficient numbers. When the Ki-74 designation was first identified in a captured Japanese document, it was thought to apply to a fighter type and was coded with the boy's name "Pat". Later, proper translation of captured documents finally confirmed that the Ki-74 was actually being developed as a bomber type, the codename was feminized to become "Patsy". The gender change of the name was an embarrassment to TAIC (the Allied group in charge of the aircraft codenames), and was one of the very few code name changes late in the war.
