Although it was much faster than the B-18 and was the first operational Army bomber equipped with a tail gun, the Dragon was soon outclassed by more modern bombers such as the North American B-25 and the Martin B-26. As a result, only 38 B-23s were built.
Douglas B-23
Dragon
The B-23 was a twin-engine bomber developed as a successor to the Douglas B-18A. First flown in July 1939, the B-23 incorporated many features of the Douglas DC-3. Although B-23s were never used in combat during WWII, they did serve in secondary roles, such as reconnaissance, training, transport and test-bed aircraft. Some were used in transport service and redesignated UC-67s. This aircraft, a UC-67, is no longer on display and is currently in storage.
