Kawanishi N1K1-J Shiden
The Kawanishi N1K1-J Shiden (Allied code name George; Japanese translation: Violet Lightning) was a land based version of the Kawanishi N1K1 Kyofu (Rex). Not only were the bulky floats removed, but a more powerful engine was fitted producing a fast and maneuverable fighter, the equal of the latest Allied aircraft. The Nakajima NK9A Homare 11 18-cylinder radial engine, produced 1650hp compared to the1,460hp of the MK4C Kasei 13 of the N1K1 Kyofu.
The mid-fuselage wing was retained, which required a long undercarriage. This proved to be structurally weak with many failures occurring. Gun armament was increased to two 20mm cannon in each wing (two of which were mounted in underwing gondolas), while retaining the two nose mounted 7.7-mm machineguns. Three other production versions were produced:
- N1K1-Ja with nose guns deleted and all cannon mounted inside the wings
- N1K1-Jb with underwing racks for two 250-kg bombs
- N1K1-Jc with racks for four 250-kg bombs
A total of 1,007 Kawanishi N1K1-J Shiden were built. The N1K1 was further developed into the Kawanishi N1K2 with a redesigned fuselage and the wing moved to the lower fuselage.
