Nine versions of this aeroplane were built for the US Navy and Coast Guard, the first appearing for the Navy in 1933 as the JF-1, powered by a 521.6kW Pratt & Whitney R-1830 Twin Wasp engine. This was followed by the JF-2 Coast Guard version, powered by a 559kW Wright Cyclone radial, and the JF-3. A number of JF-2s were also delivered to Argentina. By the beginning of 1941 about 115 JF and J2F-1 to J2F-4 Ducks were in service as general/utility amphibians for photographic, target-towing, scouting and rescue work. These were followed by J2F-5s and J2F-6s, the latter produced in 1944 by the Columbia Aircraft Corporation of Valley Stream, Long Island, under licence from Grumman, bringing the total number of JF/J2Fs built to over 600.
