Prototype N1KI first flew in 1942 aircraft had
problems with its contra-rotating propellers they were designed to offset the prop-torque during take-off and also experienced problems with the gear box.
The 1460hp Mitsubishi MK4D Kasei was a large
14-cylinder, air-cooled radial and takeoff required much skill on the part of the pilot to deal with the high engine torque.


The second prototype N1KI had a standard three blade propeller installed, and was powered by a
Mitsubishi 1460hp MK4C Kasei 13 engine that powered the second prototype and early production models. Later models were powered by the Mitsubishi MK4E Kasei 15 engine. Production of the N1K1 was about(15)aircraft per-month.

Aircraft was ordered into production, and 97 were produced before wars end. The N1K1 Rex, was designed to support offensive operations, However by 1943 the Imperial Navy found itself fighting a defensive war from land bases and had no need for such a floatplane fighter.


Surviving Rex seaplanes were later based at Lake Biwa in Japan during 1944, along with Nakajima A6M2-N(Rufe)seaplane fighters for air defense.
