Douglas TBD «Devastator» from Sq VT-2 from an aircraft carrier "Lexington"

The Douglas TBD-1 was the Navy's first widely-used monoplane shipboard plane. Designed to carry a heavy torpedo below the fuselage, it was necessarily a large aircraft and its 900-horsepower Pratt & Whitney R-1830 "Twin Wasp" radial engine could drive it to a maximum speed of slightly over 200 miles per hour.

In 1937 the TDB represented a major improvement over the earlier biplane torpedo bombers of the USN. But in 1941 it was obsolete, and suffered heavy losses.
