In 1962, the U.S. Navy performed successful test flights of an experimental seaplane fitted with a super-cavitating hydrofoil system. The aircraft used for these tests was a U.S. Coast Guard Grumman JRF-5 <i>Goose</i> (BuNo 37782) loaned to the U.S. Navy for these tests. The single, high-speed foil was mounted between ventilating struts below the aircraft’s center of gravity. The two skis extending forward of the bow stabilized the aircraft during landing and takeoffs and prevented diving in the event the foil is damaged or destroyed.  The tests were conducted for the U.S. Navy’s Bureau of Naval Weapons by the EDO Corporation of College Park, New York (USA). The photograph was released on 8 October 1962.
