The B-23 Dragon was a twin-engined aeroplane developed by Douglas Aircraft Company as a successor to (and a refinement of) the B-18 Bolo. The design of the B-23 was very similar to that of the Douglas DC-3. It was the first operational bomber equipped with a tail gun. It first flew on July 27, 1939

While significantly faster and better armed than the B-18, the B-23 found itself inferior to newer bombers like the B-25 Mitchell and B-26 Marauder. For this reason, the 38 B-23s built were never used in combat. They worked in training, reconnaissance, transport (the UC-67), and test-bed rôles. One of the UC-67 is being reconverted to B-23 configuration by the USAF Museum.
