By the time the definitive B-17G appeared, the number of guns had been increased from seven to 13, the designs of the gun stations were finalized, and other adjustments were completed. The B-17G was the final version of the Flying Fortress, incorporating all changes made to its predecessor, the B-17F, [ 63 ] and in total, 8,680 were built, [ 74 ...
More than 10,000 B-17s were produced, but only a few survive today, according to Boeing. The B-17G Flying Fortress was equipped with 11 to 13 machine guns and capable of a 9,600-pound 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 ...
Leveling out, Zeamer continued to pilot the B-17 despite excruciating pain and continued blood loss. Correctly assuming that the forward machine guns were now inoperable, the Japanese pilots began lining up on both sides of Old 666 to circle around, one by one in turn, to strafe from the front. Zeamer was now able to execute the technique that ...
Although the combat box was initially designed around a group of airplanes, it was expanded to include a formation of three groups flying together as a "combat wing", all of which were based on the same triangular design of a leading bomber (or grouping of bombers) in the center, and two bombers (or groupings) immediately behind in a vee shape, with one at an altitude above and one below the ...
The design was mainly deployed on the B-17 Flying Fortress and the B-24 Liberator, as well as the United States Navy's Liberator, the PB4Y-1. The ventral turret was used in tandem in the Convair B-32, successor to the B-24. Ball turrets appeared in the nose and tail as well as the nose of the final series B-24.
Two television cameras were fitted: one in the cockpit to show the main instrumentation panel and one in the nose to show a forward view during the target run, to be transmitted back to an accompanying B-17 "CQ-4" 'mothership'. [citation needed] [9] A precision radio altimeter, connected to the aircraft's C1 autopilot, was fitted. A whip aerial ...
In the attack, seven YB-40s were dispatched to Saint-Nazaire; they were unable to keep up with B-17s on their return from the target and modification of the waist and tail gun feeds and ammunition supplies was found to be needed. The YB-40s were sent to Technical Service Command at the Abbots Ripton 2nd Strategic Air Depot for modifications.
