COMMENT: The estimated excellent performance of  this aircraft, designed for the US Navy, was of great interest for the US Army Air Force, too. So the third (of three) prototype was delivered to the US Army Air Force and tested at Eglin Air Force base. But the advent of new jet fighters led to the cancellation of many wartime piston-engined projects. So consequently, the USAF lost interest in pursuing the project and the prototype was scrapped.
