A6M5-K two-seat trainer

The A6M5-K Model 22 was a two-seat tandem advanced fighter trainer version of the basic A6M5. It was similar to the A6M2-K, a two-seat adaptation of the earlier A6M2.

The Sasebo Naval Air Arsenal undertook the project design, and work on the prototypes began in August of 1944. Production was to be carried out by Hitachi, but only a small experimental batch of seven A6M5-Ks were built in March of 1945. By this time, the deteriorating course of the Pacific War had placed emphasis on combat aircraft, and no more two-seat A6M5-Ks were built.
