The Boeing B-24, also known as the Liberator, was a heavy bomber used extensively during World War II. Designed by Boeing, it first flew in 1939 and became one of the most produced aircraft of the war, with over 18,000 units built. The B-24 was known for its long range and large payload capacity, making it effective for strategic bombing missions. Equipped with four engines, the B-24 could carry a variety of bombs and was used by the United States Army Air Forces and other Allied forces. Its distinctive high-wing design and twin tail booms set it apart from other bombers of the era, such as the Boeing B-17.
