The fourth production F11C-2 (Goshawk) was completed with manually-operated retractable main undercarriage members accommodated by a deepened forward fuselage. It was powered by an R-1820-80 Cyclone rated at 700hp at 2440m, and was delivered to the US Navy on 27 May 1933 as the XF11C-3. Twenty-seven production models were ordered as F11C-3s with raised aft turtle decks, partial canopies and the metal wings that had proved satisfactory on the XF11C-1. Prior to the commencement of deliveries on 7 October 1934, the designation was changed to BF2C-1. The BF2C-1 carried an armament of two 7.62mm Brownings and made provision for a single 215kg bomb or up to four 53kg bombs. An R-1820-04 Cyclone rated at 770hp for takeoff was fitted. In the event, at cruising rpm the Cyclone set up a sympathetic vibration with the metal wing structure, the aircraft shaking dramatically in this regime, and, the problem never being satisfactorily resolved, the BF2C-1s were withdrawn within a few months.
