20,189 | The Mustang was designed to use the Allison V-1710 engine, which had limited high-altitude performance in its earlier variants. The aircraft was first flown operationally by the RAF as a tactical-reconnaissance aircraft and fighter-bomber (Mustang Mk I). Replacing the Allison with a Rolls-Royce Merlin resulted in the P... | https://en.wikipedia.org/wiki?curid=24710 |
20,190 | From late 1943, P-51Bs and P-51Cs (supplemented by P-51Ds from mid-1944) were used by the USAAF's Eighth Air Force to escort bombers in raids over Germany, while the RAF's Second Tactical Air Force and the USAAF's Ninth Air Force used the Merlin-powered Mustangs as fighter-bombers, roles in which the Mustang helped ens... | https://en.wikipedia.org/wiki?curid=24710 |
20,191 | At the start of the Korean War, the Mustang, by then redesignated F-51, was the main fighter of the United States until jet fighters, including North American's F-86, took over this role; the Mustang then became a specialized fighter-bomber. Despite the advent of jet fighters, the Mustang remained in service with some ... | https://en.wikipedia.org/wiki?curid=24710 |
20,192 | In 1938, the British government established a purchasing commission in the United States, headed by Sir Henry Self.

Self also sat on the British A... | https://en.wikipedia.org/wiki?curid=24710 |
20,193 | North American Aviation (NAA) was already supplying its T-6 Texan (known in British service as the "Harvard") trainer to the RAF, but was otherwise underused. NAA President "Dutch" Kindelberger approached Self to sell a new medium bomber, the North American B-25 Mitchell. Instead, Self asked if NAA could manufacture P-... | https://en.wikipedia.org/wiki?curid=24710 |
20,194 | John Attwood of North American spent much time from January to April 1940 at the British Purchasing Commission's offices in New York discussing the British specifications of the proposed aircraft with British engineers.

20,195 | The British Purchasing Commission stipulated armament of four .303 in (7.7 mm) machine guns (as used on the Tomahawk), a unit cost of no more than $40,000, and delivery of the first production aircraft by January 1941. In March 1940, 320 aircraft were ordered by Freeman, who had become the executive head of the Ministr... | https://en.wikipedia.org/wiki?curid=24710 |
20,196 | The NA-73X, which was designed by a team led by lead engineer Edgar Schmued, followed the best conventional practice of the era, designed for ease of mass manufacturing. The design included several new features. One was a wing designed using laminar flow airfoils, which were developed co-operatively by North American A... | https://en.wikipedia.org/wiki?curid=24710 |
20,197 | The other feature was a new cooling arrangement positioned aft (single ducted water and oil radiators assembly) that reduced the fuselage drag and effects on the wing. Later, after much development, they discovered that the cooling assembly could take advantage of the Meredith effect: in which heated air exited the rad... | https://en.wikipedia.org/wiki?curid=24710 |
20,198 | The prototype NA-73X was rolled out in September 1940, just 102 days after the order had been placed; it first flew on 26 October 1940, 149 days into the contract, an uncommonly short development period, even during the war. With test pilot Vance Breese at the controls, the prototype handled well and accommodated an im... | https://en.wikipedia.org/wiki?curid=24710 |
20,199 | While the USAAC could block any sales it considered detrimental to the interests of the US, the NA-73 was considered to be a special case because it had been designed at the behest of the British. In September 1940, a further 300 NA-73s were ordered by the MAP. To ensure uninterrupted delivery, Colonel Oliver P. Echols... | https://en.wikipedia.org/wiki?curid=24710 |
