 Vought XSB3U

The Vought XSB3U was an American biplane scout bomber developed by Vought-Sikorsky for the United States Navy during the 1930s.Developed as an alternative to the SB2U Vindicator monoplane, the aircraft proved unsatisfactory to the Navy in comparison, and development was not pursued.In late 1934, the U.S. Navy's Bureau of Aeronautics (BuAer) issued a specification for new scout bomber and torpedo bomber designs.
