The OS2U-1 was a two-place low-wing monoplane designed to operate from land, carrier, battleship or cruiser.  It was the first Vought production airplane to have an all- metal monocoque structure and also the first airplane to use spot welding on a production model.  During WW II it became known as the “saver of men” for the many rescues of downed airmen.  It became the oldest Vought aircraft in the United States when one was refurbished and displayed on the USS North Carolina memorial.  The OS2U-1 was convertible from landplane to seaplane configuration by substituting a float for the landing gear.  The seaplane configuration operated from cruisers and battleships while the landplane operated from carriers and land bases.
