On August 20, 1935, it made a 2,100 mile (3,380 km) non-stop flight from Seattle to Wright Field in nine hours with an average speed of 232 mph (373 km/h). The first flight of the Model 299 was on Jand it began breaking records almost immediately. The XB-15 was a larger version of the B-17, but it was considered experimental. It was powered by four 750 hp Pratt & Whitney R-1690 Hornets. It was a semi-monocoque all-aluminum fuselage and the pilot and copilot sat side-by-side in a conventional cockpit. The B-17 prototype used some of the same construction techniques as the Boeing 247. The B-17 (Model 299) was a cross between theīoeing 247 passenger airliner and the experimental XB-15 (Model 294). ![]() The 299 would be built at Boeing’s expense and there would be no reimbursement if it did not win a contract.Īfter Boeing failed to win a contract to produce theīoeing B-9, the Model 299 was a make-or-break gamble for Boeing. The most significant rival to the Model 299 was the Douglas DB-1, which was based on theĭouglas DC-2. Speed of 200 to 250 mph (322 to 402 km/h).Ī Boeing design team began work on the Model 299 prototype in June 1934 and construction began in August of the same year.1 The requirement was for a multi-engine bomber to be used for coastal-defense. While the performance of the B-10 was considered adequate at the time, the Keystones lumbered along at about 115 mph (185 km/h), were very unmaneuverable, lightly armed and carried only a limited bomb load. The Flying Fortress was designed in response to a USAAC competition, announced on August 6, 1934, to find a modern replacement for the assorted twin-engine As refinements progressed, along with better pilot training and tactics, it became a formidable weapon in the Allied war against Germany. Its first bombing mission was with the RAF as Fortress Is, but it was hardly ready for war. The first missions were in daylight hours to improve accuracy, but this strategy plus a lack of adequate fighter coverage, resulted in very heavy losses of aircraft and crew. The B-17 served in almost every theater of World War II, but it was used mostly by the US Eighth Air Force, based in the UK, to bombard German targets.
