In 1941 before the USA entered World War II, Northrop and <a href="/wiki/Convair" title="Convair">Consolidated Vultee Corporation</a> had been commissioned to develop a large wing-only, long-range bomber designated XB-35 and XB-36. Northrop advocated a "flying wing" as a means of reducing <a href="/wiki/Parasitic_drag" title="Parasitic drag">parasitic drag</a> and eliminating structural weight not directly responsible for producing lift. Consolidated Vultee proposed a more conventional design with fuselage and tail, which was much larger and heavier. In theory, the B-35 could carry a greater payload faster, farther, and cheaper than a conventional bomber. </p><p>In December 1941, the Army Air Forces awarded prototype contracts to both Northrop and Consolidated Vultee for a bomber that could carry 4,500 kg (10,000 lb) of bombs to a round-trip mission of 16,000 km (10,000 mi). Requested performance was a maximum speed of 720 km/h (450 mph), cruise speed of 443 km/h (275 mph), and service ceiling of 14,000 m (45,000 ft). This aircraft would be able to bomb Nazi-occupied Europe in the event that <a href="/wiki/United_Kingdom" title="United Kingdom">Britain</a> fell (this was similar to Nazi Germany's own <i><a href="/wiki/Amerikabomber" title="Amerikabomber">Amerikabomber</a></i> program design competition through the <a href="/wiki/Reichsluftfahrtministerium" class="mw-redirect" title="Reichsluftfahrtministerium">RLM</a>, itself initiated in the spring of 1942).

Unlike conventional aircraft, truly "tailless" flying wings do not have a <a href="/wiki/Rudder" title="Rudder">rudder</a> for lateral control, so a set of clamshell-like, double split flaps (so-called <a href="/wiki/Flaperon" title="Flaperon">flaperon</a>, a portmanteau of flap and aileron) on the trailing edge of the wingtips were used. When <a href="/wiki/Aileron" title="Aileron">aileron</a> control was input, they were deflected up or down as a single unit, just like an aileron. When rudder input was made, the two surfaces on one side opened, top and bottom, creating drag, and yawing the aircraft. By applying input to both rudder pedals, both sets of surfaces were deployed creating drag so that the airspeed or the glide angle could be manipulated.<sup id="cite_ref-Winchester_P._193_4-1" class="reference"><a href="#cite_note-Winchester_P._193-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Variants">Variants</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Northrop_YB-35&action=edit&section=2" title="Edit section: Variants"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-heading mw-heading3"><h3 id="XB-35">XB-35</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Northrop_YB-35&action=edit&section=3" title="Edit section: XB-35"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>On 22 November 1941, the <a href="/wiki/United_States_Army_Air_Forces" title="United States Army Air Forces">United States Army Air Forces</a> (USAAF, or AAF) signed the development contract for an XB-35;<sup id="cite_ref-Allen_p5_5-0" class="reference"><a href="#cite_note-Allen_p5-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> the contract included an option for a second aircraft, which was exercised on 2 January 1942.

Meetings were called by Northrop, of the AAF, Pratt & Whitney and Hamilton Standard where no one would take responsibility for correcting the AAF's engines and propellers. In addition, the AAF failed to supply the AC electrical alternator, insisting on Northrop using an onboard <a href="/wiki/Auxiliary_power_unit" title="Auxiliary power unit">auxiliary power unit</a> (APU) unit driven by an automotive engine which limited the high-altitude, high-speed XB-35 to test flights below 15,000 ft (4,600 m).

Concurrently, the AAF ordered Northrop to convert two of the YB-35 airframes to YB-49s, essentially substituting eight jet engines for four reciprocating engines. As a result, the airframe promptly flew to more than 40,000 ft (12,000 m) and topped 520 mph (840 km/h) in flight tests, verifying the XB-35 air frame's aerodynamics, but at the price of range. The prop-version had a design range capable of reaching targets 4,000 mi (6,400 km) away, but the jet-engine version's range was cut nearly in half. The new version disqualified it for the Air Force's top-priority mission as a strategic bomber, which at that time meant striking at the USSR's industrial and military complexes in the Ural Mountains.<sup id="cite_ref-Microfilm_11-0" class="reference"><a href="#cite_note-Microfilm-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> The Air Force, itself involved in a confusion of rank and job changes, eventually cancelled the XB-35 project, while continuing testing the B-35 airframe as the YB-49, even ordering 30 of the jet-powered bombers after the first YB-49 crashed.

After only 19 flights, Northrop grounded the first XB-35; the second aircraft was grounded after eight test flights. During this time, the contra-rotating propellers were removed and replaced with four-blade single-rotation propellers. In addition to having continued drive shaft vibration problems, the new single-rotation props greatly reduced the aircraft's speed and performance.

Another contributing factor to the program's failure was the tendency of Northrop to become engaged in many experimental programs, which spread its small engineering staff far too wide. While the competing propeller-driven B-36 was obsolete by that time and had just as many or even more development problems, the Air Force needed a very long-range, post-war atomic bomber to counter the perceived Soviet threat. It had more faith that the B-36's "teething" problems could be overcome, compared to those of the new and radical "Flying Wing", the unofficial name that was later associated with all the Northrop "all-wing" designs. </p><p>There are long-standing <a href="/wiki/Conspiracy_theory" title="Conspiracy theory">conspiracy theories</a> about the cancellation of the Flying Wing program; specifically, an accusation from Jack Northrop that <a href="/wiki/Secretary_of_the_Air_Force" class="mw-redirect" title="Secretary of the Air Force">Secretary of the Air Force</a> <a href="/wiki/Stuart_Symington" title="Stuart Symington">Stuart Symington</a> attempted to coerce him to merge his company with the Atlas Corporation-controlled <a href="/wiki/Convair" title="Convair">Convair</a>. In a 1979 taped interview, Jack Northrop claimed the Flying Wing contract was cancelled because he would not agree to a merger because Convair's merger demands were "grossly unfair to Northrop." When Northrop refused, Symington supposedly arranged to cancel the B-35 and <a href="/wiki/Northrop_YB-49" title="Northrop YB-49">B-49</a> program. Symington became president of Convair after he left government service a short time later.<sup id="cite_ref-18" class="reference"><a href="#cite_note-18"><span class="cite-bracket">[</span>18<span class="cite-bracket">]</span></a></sup> </p><p>Other observers note that the B-35 and B-49 designs had well-documented performance and design issues while the Convair B-36 needed more development money.<sup id="cite_ref-19" class="reference"><a href="#cite_note-19"><span class="cite-bracket">[</span>19<span class="cite-bracket">]</span></a></sup> At that time, it appeared the B-36 program might be cancelled as well as the B-35. The USAF and the Texas Congressional delegation desired to have a production program for the large Fort Worth aircraft production factory, and Convair had much more effective lobbyists in Washington, DC. The Northrop Corporation was always a technological trailblazer, but the independent nature of Jack Northrop often collided with the political wheeling-and-dealing in Washington that tended to run huge military allocations. Consequently, the B-36 prevailed, with just over 380 aircraft built. Furthermore, earlier the same year, when the YB-49 jet bomber was cancelled, Northrop received a smaller production contract for its <a href="/wiki/Northrop_F-89_Scorpion" title="Northrop F-89
