The B-17 evolved through numerous design advances [4] [5] but from its inception, the USAAC (from 1941 the United States Army Air Forces, USAAF) promoted the aircraft as a strategic weapon. It was a relatively fast, high-flying, long-range bomber with heavy defensive armament at the expense of bomb load.
The B-17B (299M) was the first production model of the B-17 and was essentially a B-17A with a slightly larger rudder, larger flaps, a redesigned nose and 1,200 hp (890 kW) R-1820-51 engines. The small, globe-like, machine gun turret used in the Y1B-17's upper nose blister was replaced with a .30 in (7.62 mm) machine gun, its barrel run through ...
The B-17G Flying Fortress was equipped with 11 to 13 machine guns and capable of a 9,600-pound bomb load. ... A B-17 with 13 people aboard crashed at a 2019 air show in Connecticut, killing seven ...
The Sikorsky bomber had a wingspan just a few feet shorter than that of a World War II Avro Lancaster, while being able to carry a bomb load of only 3% of the later aircraft. [2] The Handley Page Type O/100 owed a lot to Sikorsky's ideas; of similar size, it used just two Rolls-Royce Eagle engines and could carry up to 2,000 lb (910 kg) of bombs.
This new fuselage was intentionally designed around twin bomb bays, each one being the same size and capacity of the B-17 bomb bays. In January 1939, the USAAC, under Specification C-212, formally invited Consolidated [7] to submit a design study for a bomber with longer range, higher speed and greater ceiling than the B-17. The specification ...

Tokyo tanks were internally mounted self-sealing fuel tanks used in the Boeing B-17 Flying Fortress and Consolidated B-24 Liberator bombers [1] during World War II.The tanks increased the B-17's total range at combat weight with 4,000–5,000 pounds (1,800–2,300 kg) of bombs by about 1,000 miles (1,600 km) and the combat radius was doubled to about 650 miles (1,050 km).
The Bally Bomber B-17 is an original design by Jack Bally, EAA 348338. [2] The aircraft is a four-engined, retractable conventional landing gear equipped, low wing monoplane. The fuselage is all riveted aluminum in construction with hexagonal bulkheads. The drawings were modified from a one ninth scale set of radio-controlled aircraft plans ...
