 Following initial testing, which found the aircraft to be reasonably faultless, the XSBF-1 was delivered to the U.S. Navy for evaluation in competition with two other biplanes submitted to the 1934 specification, the Great Lakes XB2G and the Curtiss XSBC-3.Unusually for biplanes, all three types possessed retractable landing gear.The evaluation showed that the design from Curtiss was superior to the Grumman and Great Lakes designs, and an order was placed for the Curtiss type, designated SBC-3 Helldiver in service, in August 1936.
