.." The first
prototype flew in December 1939, and, by the
spring of 1941, B-24s were being delivered to the British
Royal Air Force on a cash-and-carry basis.
... The first version of the
Liberator considered battle-worthy by the USAAF was the B-24D, with turbo-supercharged engines and powered turrets mounting twin 0.50-inch (12.7-mm) machine guns on the upper fuselage and tail. Subsequent models acquired additional armament, and the B-24H and J models, which began entering service in early 1944, added powered nose and belly turrets and sported a total of 10 0.50-inch machine guns. Like the
B-17 Flying Fortress, the B-24 was flown in defensive “box” formations, though the boxes could not be stacked as closely because the
Liberator was appreciably more difficult to fly in formation.
...On high-altitude missions the
Liberator had a maximum range of nearly 1,600 miles (2,600 km)—40 percent greater than that of its partner the B-17—but it had a service ceiling of only 28,000 feet (8,500 metres), some 7,000 feet (2,100 metres) below that of the B-17. As a result, the B-24 was more exposed to German antiaircraft artillery; this and the B-24’s greater vulnerability to battle damage (
the leaky fuel system was a particular problem) made the B-17 the preferred strategic bomber in the European theatre. Still, B-24s equipped one entire bomb division of the 8th Air Force and, because of their greater range, were assigned some of the most difficult targets in the latter stages of the war in
Europe. "...
