The North American F-86 Sabre was a transonic jet fighter aircraft. Produced by North American Aviation, the Sabre is best known as America's first swept wing fighter which could counter the similarly-winged Soviet MiG-15 in high speed dogfights over the skies of the Korean War. Considered one of the best and most important fighter aircraft in the Korean War, the F-86 is also rated highly in comparison with fighters of other eras. Although it was developed in the late 1940s and was outdated by the end of the 1950s, the Sabre proved versatile and adaptable, and continued as a front-line fighter in numerous air forces until the last active operational examples were retired by the Bolivian Air Force in 1994. Its success led to an extended production run of more than 7,800 aircraft between 1949 and 1956, in the United States, Japan and Italy. Variants were built in Canada and Australia. The Canadair Sabre added another 1,815 airframes, and the significantly redesigned CAC Sabre (sometimes known as the Avon Sabre or CAC CA-27), had a production run of 112. It was by far the most-produced Western jet fighter, with total production of all variants at 9,860 units. The F-86A set its first official world speed record of 670 miles per hour (1,080 km/h) in September 1948. Several people involved with the development of the F-86, including the chief aerodynamicist for the project and one of its other test pilots, claimed that North American test pilot George Welch had unofficially broken the sound barrier in a dive with the XP-86 while on a test flight on 1 October 1947. Chuck Yeager broke the sound barrier on 14 October 1947 in the rocket-propelled Bell X-1 during level flight, making it the first true supersonic aircraft. Five years later, on 18 May 1953, Jacqueline Cochran became the first woman to break the sound barrier, flying a "one-off" Canadian-built F-86 Sabre Mk 3, alongside Chuck Yeager. The F-86 entered service with the United States Air Force in 1949, joining the 1st Fighter Wing's 94th Fighter Squadron "Hat-in-the-Ring" and became the primary air-to-air jet fighter used by the Americans in the Korean War. While earlier straight-winged jets such as the F-80 and F-84 initially achieved air victories, when the swept wing Soviet Mikoyan-Gurevich MiG-15 was introduced in November 1950, it immediately outperformed all UN-based aircraft. In response, three squadrons of F-86s were rushed to the Far East in December. Early variants of the F-86 could not outturn, but they could outdive the MiG-15, and the MiG-15 was superior to the early F-86 models in ceiling, acceleration, rate of climb, and zoom. With the introduction of the F-86F in 1953, the two aircraft were more closely matched, with many combat-experienced pilots claiming a marginal superiority for the F-86F. MiGs flown from bases in Manchuria by Red Chinese, North Korean, and Soviet VVS pilots were pitted against two squadrons of the 4th Fighter-Interceptor Wing forward-based at K-14, Kimpo, Korea. By the end of hostilities, F-86 pilots were credited with shooting down 792 MiGs for a loss of only 78 Sabres, a victory ratio of 10:1. More recent research by Dorr, Lake and Thompson has claimed the actual ratio is closer to 2:1. The Soviets claimed to have downed over 600 Sabres, together with the Chinese claims, although these are thought by some to be an overcount as they cannot be reconciled with the the 78 Sabres recorded as lost by the US. A recent RAND report made reference to "recent scholarship" of F-86 v MiG-15 combat over Korea and concluded that the actual kill:loss ratio for the F-86 was 1.8:1 overall, and likely closer 1.3:1 against MiGs flown by Soviet pilots. Of the 41 American pilots who earned the designation of ace during the Korean war, all but one flew the F-86 Sabre, the exception being a Navy Vought F4U Corsair night fighter pilot.
