Amazing plane. It was included in the 1946 add-on of 'Aces of the Pacific'.
Could it do 466 at 30.000 feet? My sources state that speed but no altitude. Didn't the Japanese have troubles with supercharging at such extreme altutide? From memory the 'Aces ' booklet states that the Shinden's power fell off dramatically at high altitudes.
If it could do 466 at 30k and would have been available, it would have been the B-29's nemesis with 4 30mm cannon.
