The landing gear was similar to that on the Brewster F2A Buffalo fighter aircraft. The SBN had non-folding wings with perforated flaps.
Development
The United States Navy issued specifications for a scout bomber in 1934 and Brewster won the competition. The Navy ordered one prototype, designated the XSBA-1, on 15 October 1934. It was a two-seat, single-engine monoplane with retractable landing gear and an internal bomb bay that could accommodate a 500-pound (227-kg) bomb. The crewman in the rear seat was armed with a flexible machine gun. and was delivered to the Navy for testing. With a Wright R-1820-4 Cyclone 770-horsepower (570-kilowatt) engine, it achieved a top speed of 254 mph (409 km/h),
