The Naval Aircraft Factory SBN was a United States three-place mid-wing monoplane scout bomber/torpedo aircraft designed by the Brewster Aeronautical Corporation and built under license by the Naval Aircraft Factory in Philadelphia, Pennsylvania. The landing gear was similar to that on the Brewster F2A fighter aircraft. The SBN had non-folding wings with perforated flaps. The United States Navy issued a specification for a scout-bomber in 1934 and the competition was won by Brewster. One prototype designated the XSBA-1 was ordered on October 15, 1934.
