On display at Florida Air Museum. This experimental VTOL aircraft was one of two prototypes built to a USN proposal to launch fighters from the afterdeck of ships. The XFV-1 was powered by a 5,850 hp Allison YT40-A-6 turboprop driving a pair of 16 ft. contra-rotating propellers. The design featured a cruciform tail with wheels mounted on struts. Called the Salmon after chief engineering test pilot Herman "Fish" Salmon, single flying prototype BuNo 138657 never achieved VTOL due to insufficient power. Fitted with a spindly fixed undercarriage, the XFV-1 was flown horizontally and held in hover.

Originally an E2C, 165812 has been converted to a Hawkeye 2000.

Lockheed's experimental VTOL project. Two were built, but the design never managed vertical take-off. The project was cancelled in 1955, leaving the second aircraft (138658) incomplete without an engine. The flying prototype 138657 was donated to Hiller Aircraft for further VTOL testing, but its fate is unclear. Reliable sources say that only parts (engine and props) of this aircraft survived these tests, others say it is the aircraft that went on display in Florida in the mid 1990s, and that for reasons unknown it was painted as 138658...
Note: this design is often quoted as "XFV-1 Salmon", but it was in fact unnamed. Salmon was the name of Lockheed's test pilot for the project. Photo from: Library of Congress
