The Huff-Daland LB-1 was an American biplane light bomber aircraft operated by the United States Army Air Service in the 1920s.
Derived from the XLB-1 prototype bought by the Army in 1923, the LB-1 development aircraft was powered by a single Packard 2A-2500 engine and carried an extra crewman. It proved underpowered in service trials, and was replaced by the twin-engined XLB-3.
