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 top horizontal line represents the maximum payload. It is limited structurally by maximum zero-fuel weight (MZFW) of the aircraft. Maximum payload is the difference between maximum zero-fuel weight and operational empty weight (OEW). Moving left-to-right along the line shows the constant maximum payload as the range increases.
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 ...
They believed the B-17 had a 1.2% probability of hitting a 30 meters (100 ft) target from 6,100 meters (20,000 ft), meaning that 220 bombers would be needed for a 93% probability of one or more hits. This was not considered a problem, and the USAAF forecast the need for 251 combat groups to provide enough bombers to fulfill their comprehensive ...
“Over-the-shoulder” delivery. Toss bombing (sometimes known as loft bombing, and by the U.S. Air Force as the Low Altitude Bombing System, or LABS) is a method of bombing where the attacking aircraft pulls upward when releasing its bomb load, giving the bomb additional time of flight by starting its ballistic path with an upward vector.

Example of a ballistic table for a given 7.62×51mm NATO load. Bullet drop and wind drift are shown both in mrad and MOA.. A ballistic table or ballistic chart, also known as the data of previous engagements (DOPE) chart, is a reference data chart used in long-range shooting to predict the trajectory of a projectile and compensate for physical effects of gravity and wind drift, in order to ...
