"Convair XFY-1 Pogo"@en . . . . . . . "After World War II, the Cold War prompted the United States Army and Navy to study VTOL operations. It was envisaged to protect task forces, convoys or any fleet, even without aircraft carriers, by placing VTOLs on any ship. These fighters would be housed within a conical protective housing, saving limited deck space available aboard ships. They would provide first line of airborne defense and reconnaissance capability, before more aircraft could be scrambled to help."@en . .

In May 1951, Lockheed and Convair were awarded contracts in the attempt to design, construct, and test two experimental VTOL fighters that would be suitable for use by the Armed forces. Although contract stipulations stated that each manufacturer have two fighters, each was only able to construct one, with Lockheed producing the XFV, and Convair producing the XFY, nicknamed the \"Pogo\". The first XFY-1 prototype was used for engine testing and the third for static testing and only the second prototype serial number 138649 was flown."@en . . .
