The Boeing B-17 Flying Fortress is a four-engine heavy bomber developed in the 1930s for the United States Army Air Corps. Known for its ruggedness, long range, and defensive firepower, the B-17 could endure extensive damage and still complete missions. It became iconic during World War II, especially in strategic bombing campaigns over Europe, where it dropped more bombs than any other U.S. aircraft. With its distinctive nose, large wingspan, and multiple gun turrets, the B-17 earned a reputation as a formidable and reliable workhorse, symbolizing American air power during the war.
