The N1K2-J variant of the formidable Kawanishi 'Shiden Kai' was developed to counter high-flying B-29s, but suffered from poor engine and climb performance over 20,000ft so did not pose a major threat. Having been abandoned in a San Diego playground, this N1K2-Ja fighter-bomber sub-type was rescued by the nascent USAF Museum in 1959 and underwent an extensive restoration from 2000 to 2008, emerging in the colours of the Yokosuka Kokutai test and evaluation unit

This George is on display at the National Museum of the USAF and is one of only three extant restored examples. It is a fighter-bomber variant equipped with wing mounts to carry bombs and is painted as an aircraft in the Yokosuka Kokutai, an evaluation and test unit similar in function to the USAAF's Flight Test Unit at Wright Field.
