Andres Erdos, e-mail, 25.08.2012 23:26 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. Two prototypes were constructed in 1945, but the project was cancelled after the incomplete prototypes were destroyed during two separate bomb attacks when they are about 70% (1st prototype) and 90% (2nd prototype) complete.
