XFV Salmon
Role Experimental VTOL fighter aircraft
Manufacturer Lockheed
First flight 23 December 1953
Primary user United States Navy (intended)
Produced 1954
Number built 1 flying prototype plus 1 incomplete airframe

The American Lockheed XFV (sometimes referred to as the Salmon [1]) was an experimental tailsitter prototype built by Lockheed to demonstrate the operation of a vertical takeoff and landing fighter for protecting convoys.

Contents

Design and development

The XFV was powered by a 5,332 hp (3,976 kW) Allison YT40-A-14 turboprop engine driving three-bladed contra-rotating propellers. The tail surfaces were a reflected cruciform v-tail (forming an x) that extended above and below the fuselage. The aircraft had an ungainly appearance on the ground with a make-shift, fixed landing gear attached.[2] Lockheed employees derisively nicknamed the aircraft the "pogo stick" (hearkening back to the rival Convair XFY [3]).

Testing and evaluation

Starting with a brief hop on 23 December 1953 piloted by Herman "Fish" Salmon, the aircraft made a total of 32 flights, demonstrating transition between horizontal and vertical flight. No vertical takeoffs were performed, however. The aircraft was fitted with fixed landing gear so that it could take off horizontally. Performance was disappointing, and the project was cancelled in June 1955.

Survivors

The single flying prototype ended up at the Sun 'n Fun Museum in Lakeland, Florida. The second prototype, which was never completed, serves as a gate guardian at NAS Los Alamitos, California.
