Chance Vought XF5U - 1

The letter of intent for the Vought VS-315 (XF5U-1) was issued September 17, 1942. The XF5U-1 was a twin-engine, single-seat, low
aspect ratio flying wing type of airplane. The first XF5U-1 airplane was used for static tests. The second XF5U-1 airplane was used
for experimental flight test and concept validation. It was never flown because many hours of engine run-up showed excessive
mechanical vibration between the engine-propeller shafting, gear boxes, and airframe structure. The airplane was taxi tested in
February 1947 at Stratford, Connecticut, but, again, vibration levels were considered excessive. The airplane was being readied for
shipment by sea through the Panama Canal to Edwards AFB, California, when the contract was canceled.

A mock-up was built in 1943.
