Full Specifications

Boeing B-17 Flying Fortress Strategic Bomber

The Boeing B-17 Flying Fortress is one of the most iconic heavy bombers in aviation history. Developed for the United States Army Air Corps during the 1930s, the aircraft became a symbol of American strategic bombing operations throughout World War II. Known for its rugged construction, extensive defensive armament, and ability to survive heavy battle damage, the B-17 earned the nickname Flying Fortress because of its numerous machine gun positions.

Manufacturer

The B-17 was designed and manufactured by Boeing, with additional production by Douglas Aircraft Company and Vega Aircraft Corporation (a Lockheed subsidiary) to meet wartime demand. More than 12,700 aircraft were produced between 1936 and 1945.

Speed and Range

Powered by four Wright R-1820 Cyclone radial piston engines, the B-17 achieved a maximum speed of approximately 287 mph (462 km/h). It had a ferry range of about 2,000 miles (3,219 km), enabling long-range bombing missions across Europe and the Pacific. The aircraft typically operated at high altitudes, where its defensive guns and formation tactics helped improve survivability.

Cost / Price

During World War II, a B-17G Flying Fortress cost approximately US$238,000 in 1945 dollars. Adjusted for inflation, this would equal several million U.S. dollars today. Since the aircraft is no longer in production, surviving examples are preserved in museums or operated by historical aviation organizations.

The B-17 could carry up to 17,600 pounds (7,983 kg) of bombs on short-range missions, although typical combat loads were lower for long-range operations. It played a decisive role in the Allied daylight strategic bombing campaign against Germany, targeting industrial centers, transportation infrastructure, and military facilities. Although later replaced by more advanced bombers such as the B-29 Superfortress, the Flying Fortress remains an enduring symbol of U.S. air power and military aviation history.
