Boeing B-17 Flying Fortress

The Boeing B-17 Flying Fortress 4-engine heavy bomber is one of the most famous, and successful, planes ever built. The B-17 received the name "Flying Fortress" from a Seattle news reporter who commented on its defensive firepower, and said "It's a Flying Fortress".

This section of Airplanes Online is meant to be a tribute to those who designed & built the B-17, the crews who flew her, and those who have worked tirelessly to preserve this famous World War II airplane and its history.

Design and Development of the Boeing B-17

The original intent for the B-17 was the protection of the U.S. mainland from invasion fleets. In 1934, the Boeing Aircraft Company of Seattle, Washington, began construction of a four-engine heavy bomber. Known as Boeing Model 299, it first took flight on July 28, 1935. The government ordered production of 13 of these aircraft, designated the Y1B-17. Delivery of these first production models was between January 11 and August 4, 1937.

When Pearl Harbor was bombed by the Japanese on December 7, 1941, few B-17s were in service. But production lines quickly ramped up, and production of B-17E, B-17F and B-17G models were produced at fast rates.

B-17 Action in World War II

B-17s served in every World War II combat zone. The aircraft is best known for daylight strategic bombing of German industrial targets. The B-17 flew mostly out of England, equipping 26 of the 40 bombardment groups of the 8th Air Force.

Early models proved to be unsuitable for combat use over Europe and it was the B-17E that was first successfully used by the USAAF.

The defense expected from bombers operating in close formation alone did not prove effective and the bombers needed fighter escorts to operate successfully.

Because of their long-range capability, formations of B-17s often flew into battle with no fighter escort, relying on their own defensive capabilities to insure a successful mission.

Following the end of World War II, the B-17 was quickly phased out of use as a bomber and the Army Air Forces retired most of its fleet.

Flight crews ferried the bombers back across the Atlantic and Pacific to the United States where the majority were sold for scrap and melted down at disposal depots such as Kingman Army Air Field in Arizona (see photo to the right).

Storage and Disposal of B-17 Flying Fortresses After World War II

Following the end of World War II, the B-17 was quickly phased out of use as a bomber and the Army Air Forces retired most of its fleet.

Flight crews ferried the bombers back across the Atlantic and Pacific to the United States where the majority were sold for scrap and melted down at disposal depots and desert boneyards such as Kingman Army Air Field in Arizona.
