The D-2's early gestation is historically obscure because Hughes Aircraft and its corporate successors have never released archives regarding the D-2; however, Howard Hughes had recently set a global circumnavigation speed record in a <a href="/wiki/Lockheed_14" class="mw-redirect" title="Lockheed 14">Lockheed 14</a>. Aircraft historian René Francillon speculates that Hughes probably initiated the project for another circumnavigation record attempt, but the outbreak of <a href="/wiki/World_War_II" title="World War II">World War II</a> closed much of the world's airspace and made it difficult to buy aircraft parts without government approval, so he decided to sell the aircraft to the U.S. military instead. The first documentary evidence of the project is a December 1939 letter from Hughes to the <a href="/wiki/United_States_Army_Air_Corps" title="United States Army Air Corps">United States Army Air Corps</a> (USAAC) proposing procurement of the D-2 and describing it as a "<a href="/wiki/Pursuit_aircraft" class="mw-redirect" title="Pursuit aircraft">pursuit</a> type airplane".<sup id="cite_ref-FOOTNOTEFrancillon199052–53_2-0" class="reference"><a href="#cite_note-FOOTNOTEFrancillon199052–53-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> The design was somewhat similar to the <a href="/wiki/Lockheed_P-38_Lightning" title="Lockheed P-38 Lightning">Lockheed P-38 Lightning</a> that won the 1939 USAAC <a href="/wiki/Interceptor_aircraft" title="Interceptor aircraft">interceptor aircraft</a> design competition.

This material was advantageous from an aerodynamic and a metals-shortage standpoint, but was difficult to work, and rejected as insufficiently robust by the USAAC. Initially, the aircraft was to have been equipped with a <a href="/wiki/Taildragger" class="mw-redirect" title="Taildragger">tail wheel</a> but the landing gear was later changed to a <a href="/wiki/Tricycle_gear" class="mw-redirect" title="Tricycle gear">tricycle</a> configuration with the main undercarriage units retracting rearwards into the twin booms and the nosewheel retracting rearwards and rotating 90 degrees to lie flat in the small central fuselage.

The USAAC had requested information about the project's progress, but did not enter into a formal contract until 1944. Final assembly and flight testing occurred at the Hughes Harper Dry Lake facility in the Mojave Desert. The finished D-2 looked like a scaled-up P-38 Lightning but, on paper, promised better performance; the USAAC repeatedly compared it to the <a href="/wiki/Lockheed_XP-58_Chain_Lightning" title="Lockheed XP-58 Chain Lightning">Lockheed XP-58 Chain Lightning</a>.<sup class="noprint Inline-Template Template-Fact" style="white-space:nowrap;">[<i><a href="/wiki/Wikipedia:Citation_needed" title="Wikipedia:Citation needed"><span title="This claim needs references to reliable sources.

However, Materiel Command engineers vehemently opposed the aircraft, partly because it was built of wood instead of aluminum, and in part because they believed Mr. Hughes had not the managerial and industrial capability to actually produce the aircraft. Neither of the above <a href="/wiki/United_States_Army_Air_Forces" title="United States Army Air Forces">USAAF</a> designations thus applied to any actual airplane; in the end, only two XF-11 prototypes and a mock-up were delivered. </p><p>Because of Mr. Hughes's high political and public profile, the program was highly controversial.

However, after only a few brief hops, it was clear that high control forces were a problem. When full flight tests were finally conducted in spring 1943, modifications still had not been made to correct this problem. Hughes reluctantly concluded that the D-2 needed major modifications, including a complete redesign of the wings and a change in airfoil section. The wing center section, which was continuous through the fuselage nacelle, was to be revised to increase the size of the proposed bomb bay. Following these changes, the aircraft was to be assigned the company designation D-5. After only a few test flights, the sole aircraft was abandoned and further development of the subsequent F-11 proceeded at Culver City.<sup id="cite_ref-Barton_p._15_10-0" class="reference"><a href="#cite_note-Barton_p._15-10"><span class="cite-bracket">[</span>9<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Aftermath">Aftermath</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Hughes_D-2&action=edit&section=4" title="Edit section: Aftermath"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In August 1943, Colonel <a href="/wiki/Elliott_Roosevelt_(general)" title="Elliott Roosevelt (general)">Elliott Roosevelt</a>, the President's son and then commander of the <a href="/wiki/Northwest_African_Photographic_Reconnaissance_Wing" title="Northwest African Photographic Reconnaissance Wing">Northwest African Photographic Reconnaissance Wing</a>, led a distinguished team tasked with evaluation of several American <a href="/wiki/Reconnaissance" title="Reconnaissance">reconnaissance</a> aircraft projects.
