In November 1938, Douglas used the stronger wings of the DC-3, a new and better streamlined fuselage, and large fin and rudder for the B-18 Bolo's successor -- the B-23 Dragon. The first of 38 B-23 Dragons built flew July 27, 1939. The 26,500-pound B-23 bomber incorporated the first tail turret installed in an Air Corps bomber and was powered by two 1,600-horsepower Wright R-2600-3 engines. Following the war, many Dragons were adapted as corporate aircraft.
