The Kawanishi N1K2-J Shiden (Violet Lightning) was codenamed “George” by the Allies. Development was interesting in that the Shiden was developed from the N1K Kyofu (Strong Wind / Rex), a floatplane.
The Shiden was heavily armed, with 4 x 20 mm cannon in the wings. It was considered the equal of the Hellcat, and could hold its own with the Corsairs and P-51s. As a bomber interceptor, it was hampered by poor rate of climb and inadequate engine performance at high altitudes.
The prototype flew in 1943, and the type entered production in January of 1944. Production never exceeded 83 per month (April and May 1945), and only 423 were produced before VJ day.
There are 4 surviving Shidens, one at the Naval Air Museum at Pensacola, one at the USAF Museum near Dayton, one at the Champlin Air Museum (on loan from the National Air and Space Museum), and one at Shikoku, Japan.
