The B-24 Liberator, an American heavy bomber, was manufactured by Consolidated Aircraft. It was designed by Isaac M. Laddon. Primarily used by USAF and USN, the Liberator first flew on December 29, 1939. It was produced in greater numbers than any other American combat aircraft of World War II and still holds the record as the most produced U.S. military aircraft. Often compared to the better known B-17 Flying Fortress, the B-24 was a more modern design with a higher top speed and greater range yet it had a similar bombload and defensive armament. Nevertheless, popular opinion among aircrews and general staff tended to favor the B-17's rugged qualities above all other considerations. A total of 18,482 B-24 Liberator was built.

As for the “H” model of the Liberator, it is a four-engine strategic heavy bomber that attained distinguished war record with its operations in the Pacific, African, Middle Eastern, and European theaters. The B-24H Liberator served in all theaters of combat, delivering large bomb loads over long distances. The Liberator’s major contribution in World War II was as a bomber, especially in the Pacific. As the most complicated and expensive long- range bomber of its time since its range of 2200 miles was greater than the B-17, more Liberators were built than any other WWII bomber. However, the model was redesigned due to its vulnerability to head-on attack. The B-24H was improved with a nose turret, generally a modified Emerson A-6 tail turret, to reduce interference during battle.
