Aichi S1A
The Aichi S1A ''Denko'' (Bolt of Light) was a Japanese night fighter, intended to replace the Nakajima J1N1-S ''Gekkou'' (Allied code name ''Irving''). It was to be, like the Gekkou, equipped with radar to counter the B-29 air raids over the Japan. Development time increased while trying to overcome design shortcomings, such as the insufficient power of the Navy's requested Nakajima Homare engines, resulting in no aircraft being completed before the war ended. ==Design and development== Because it was full of special equipment the Denko's service weight exceeded ten thousand kilograms. Some of this specialized equipment included oxygen injection but the turbocharger's remote location from the engine caused many problems. Because the initial prototypes' engines did not pass Navy standards only two were ever manufactured. Two more had been planned before cancellation that would have used the more powerful Mitsubishi HI MK9A Ru or MK10A Ru engines. Additionally, Tonankai earthquake occurred in December 1944 and the aircraft factories and prototypes were badly damaged. On 1945 June 9 the airstrikes on Aichi Kokuki KK and Aichi Tokei Denki Seizo Co., Ltd blew up the first prototype and forced movement of the second to the Gifu large Sadakazu factory to be assembled. But on July 9 of that year the another airstrike destroyed the second prototype. To date it is still the most massive fighter developed in Japan's naval history.
