Douglas DT-2

The Douglas DT was the Douglas Aircraft Company's first military contract and the aircraft that began the firm's long association with the U.S. Navy. Ordered in 1921, the DT (D for Douglas, T for torpedo) was a large two-seat biplane torpedo bomber that first flew in November 1921. The refined DT-2 became the principal production model, powered by a 450-hp Liberty V-12 engine and able to operate on either wheeled landing gear or floats.

It could carry a Mark VIII aerial torpedo weighing roughly 1,800 pounds or an equivalent bomb load. The DT-2 flew from the Navy's first aircraft carrier, USS Langley, as well as from land bases and seaplane tenders. Reliable and adaptable, it established Douglas as a trusted Navy supplier and remained in service through much of the 1920s.
