Thanks! But Uhu is one of the most handsome fighter for me.
To hear B-29's completion in 1943, the INJ ordered Aichi to develop authentic night fighter.
The IJN's request for this night fighter was as follows.
Maximum speed ; 685km/h(370kt)/9000m, Endurance ; 5hours(4000m), Time climb to 6,000m ; 8 minutes, Take off run ; under 400m, Armament ; 2× 30mm canons, With radar.
Aichi concentrated to develop this fighter with there all resources from November 1943, finished design in May 1944, completed mock up in August 1944. Aichi judged it's maximum speed was only 629km/h(340kt) with Homare(NK9K) engine (IJN's request),they planned to use turbocharger to realize 679km/h(367kt) maximum speed, but it's difficult for Aichi to develop turbocharger quickly, they changed design to use oxygen injection into the engine cylinder and forced cooling fan , then estimated maximum speed became 635km/h(343kt) and finally became 588km/h(318kt). The armaments ; 2×30mm or 20mm canon(nose) and 2 ×20mm remote controlled turret behind the cockpit. There was a speed brake bottom of the fuselage for same speed flight when B-29 interception. No.1 aircraft(95% completed) was destroyed in 3/12/1945 by B-29 bombing prior to destroy B-29.
