Vought V-141
 The Vought V-141 (which was later redesignated V-143 after modification) was a prototype American single-seat fighter aircraft of the 1930s. It was a development of the unsuccessful Northrop 3-A design but was itself a failure being rejected by the United States Army Air Corps. The sole prototype was sold to the Japanese Army in 1937 but no production followed with the type proving to be inferior to existing Japanese fighters.
