A7M1 Reppū First prototype powered by a 2,000 hp (1,500 kW) Nakajima Homare 22 engine, with a maximum speed of 574 km/h (356 mph). The armament consisted of two 13.2 mm (.52 in) Type 3 machine guns and two 20 mm (.80 in) Type 99 autocannon in the wings.

在十七試艦戰（A7M1）原型機機翼內設置 整體式燃料箱，總容量910升，最後在A7M2改為機身駕駛艙之間後部700升自封燃料箱和機翼內的普通防彈燃料箱（各容量105升）。

2020年4月10日 · On May 6, 1945 The Mitsubishi A7M1, Navy Experimental 17-Shi Ko (A) Type Carrier Fighter Reppu (Hurricane) makes its first flight. The aircraft had been under development since 1942 as a replacement for the Mitsubishi A6M, Navy …

In Jul 1942, the Japanese Navy issued specific requests for this aircraft, already designated Navy Experimental 17-shi Ko Type Carrier Fighter, which demanded a top speed of 639 kilometers per hour, ceiling of 6,000 meters, being able to climb to 6,000 meters in 6 minutes, having two 20-millimeter cannon and two 13-millimeter machine guns, and k...

A cantilever low-wing monoplane with retractable tailwheel landing gear, the A7M1 soon revealed excellent flight characteristics, but as predicted by Mitsubishi the type's maximum speed on the power of the installed Nakajima NK9K Homare 22 engine was below specification.

The resulting prototype - known as the A7M1 - flew for the first time on May 6, 1944. The installed Nakajima Homare 22-series engine (2,000 hp) was underwhelming, but control and agility proved solid. Ultimately, three A7M1 prototypes were built.

Mitsubishi A7M Reppu (Strong Gale), designed as the successor to the Imperial Japanese Navy's A6M Zero with development beginning in 1942. Performance objectives were to achieve superior speed, climb, diving, and armament over the Zero, as well as better maneuverability.

The A7M1 (NK9H), designated as 17-Shi, Reppū (十七試, 烈風), was a pre-production model of the Reppū, the A6M Zero successor. It was developed since late 1940, but faced many delays due to the Navy's high expectations and the lack of powerful engine…

2008年5月11日 · We are to believe that Reppu was capable for 390 mph, on engine power size similar to P-47D (~ 430 mph). Grumman conceived F8F to be small light enough, so it would fit better on small carriers, while being to climb much better than F6F. Good as it was, F8F was unable to beat the F4U-4 and later as all-around CV fighter.
