The Consolidated B-24 Liberator was a heavy bomber used by the United States during World War II. It was designed by the Consolidated Aircraft Corporation and first flew in 1939. Known for its distinctive high-wing design and twin tail, the B-24 was one of the most produced bombers of the war, with over 18,000 units built. The B-24 was notable for its long range and large payload capacity, allowing it to carry more bombs than its predecessor, the B-17 Flying Fortress. It served in various theaters of war, including the European and Pacific fronts, and was used for strategic bombing, reconnaissance, and transport missions.
