First flown by the U.S. military in May 1940, it was the first fighter plane to reach 644 kilometers per hour. It was mass-produced for 11 years and used in the Korean War. Its unique gull wing design was conceived due to the size of the propeller. This model is a product of Otaki, the predecessor of Arai Seisakusho. Naturally, it is no longer manufactured and is a rather rare aircraft. It is traded at a considerable price. I've also included my favorite figure. Category...U.S. Air Force Category...U.S. Navy
