>The V-173 and F5U design was considered promising, and possibly capable of great maneuverability and speeds of up to 452 mph (727 km/h).[6] Two prototypes were constructed. Taxi trials of the XF5U-1 at Vought's Connecticut factory culminated in short "hops" that were not true flights.[7] Suggestions that the XF5U-1 flew were likely a result of confusion with the V-173, which underwent flight tests until 1945.[8] During these ground runs the XF5U-1 reportedly experienced severe vibration problems.[7]

>By 1946, the project was long over its expected development time, and well over budget.[2] With jet aircraft coming into service, the US Navy officially canceled the F5U project on 17 March 1947. The only completed XF5U-1 proved to be so structurally solid that it had to be destroyed with a wrecking ball.[9] The prototype V-173 was transferred to the Smithsonian Museum for displa
