One XFG-1 was ordered by the US Navy with serial A-7944 and flew for the first time in June 1927. It was later converted as XF2G-1, with a larger wing and a single float. The FG designation was later used for the Goodyear licence built Corsair.

A number of FG-1s were converted with wing mounted radar pods as FG-1E whilst the FG-1K designation was assigned to target drone conversions of the FG-1. With the FG-2 designation not having been assigned, the FG-3 was used for 13 FG-1s converted to XF4U-3 standards with an XR-2800-1 engine. Serials included 76450. The FG-4 designation was applied to a proposed version similar to the F4U-4, with a length of 33'8", 10.26 m and a R-2800-18W engine.

Two FG-1s and five FG-1Ds were converted as XF2G-1 prototypes. The first flight was in May 1944 and known serials include 12992, 13471, 13472 and 14691/14695. The aircraft was ordered in production in March 1944 as F2G-1 and F2G-2, the latter being a carrier version. As it was, this order was cut back in May 1945 and only five F2G-1s were completed with serials 88454/88458 whilst 413 with serials 88469/88871 were cancelled. Five F2G-2s were built with serials 88459/88463 with another five with serials 88464/88468 having been cancelled. Refer also to F3A, FG, AU, F4U
