In 1951, a MikoyanGurevich MiG15 was shot down over Korea's west coast and plummeted into the Yellow Sea.
US and South Korean forces pulled the jet from the shallow water and transported it by a British frigate for study.
The plane is poured over at a US Air Force base in Dayton, Ohio. One of the first discoveries of this incredible aircraft comes when the engine is inspected. Expecting to find a hybrid of Russian and
German jet technology, the teams studying the captured prize receive a shock. The plane
is powered by what appears to be a RollsRoyce Neen II, designed in England.
The MikoyanGurevich MiG15 (Russian: МикоянГуревич МиГ15; USAF/DoD designation: Type 14; NATO reporting name: Fagot) is a jet fighter aircraft developed by MikoyanGurevich for the Soviet Union. The MiG15 was one of the first successful jet fighters to incorporate swept wings to achieve high transonic speeds. In aerial combat during the Korean War, it outclassed straightwinged jet day fighters, largely relegated to groundattack roles. In response to the MiG15's appearance and to counter it, the United States Air Force rushed the North American F86 Sabre to Korea.
When refined into the more advanced MiG17, the basic design would again surprise the West when it proved effective against supersonic fighters such as the Republic F105 Thunderchief and McDonnell Douglas F4 Phantom II in the Vietnam War of the 1960s.
The MiG15 is believed to be one of the most produced jet aircraft, with over 13,000 manufactured. The MiG15 remains an advanced trainer with the Korean People's Army Air Force.
The first turbojet fighter developed by MikoyanGurevich OKB was the MikoyanGurevich MiG9, which appeared in the years immediately after World War II. It used a pair of reverseengineered German BMW 003 engines. The MiG9 was troublesome, with weak, unreliable engines and control problems. It was categorized as a firstgeneration jet fighter and designed with straightstyle wings common to pistonengined fighters.

In 1946, Soviet engine technology was far behind that of the West. The Germans had been unable to develop airworthy turbojets with thrust over 1,130 kilogramsforce (11,100 N; 2,500 lbf) capable of running for more than a few hours at the time of the surrender in May 1945, which limited the performance of immediate Soviet postwar jet aircraft designs. The Soviet aviation minister Mikhail Khrunichev and aircraft designer A. S. Yakovlev suggested to Premier Joseph Stalin that the USSR buy the reliable, fully developed RollsRoyce Nene (having been alerted to the fact that the U.K. Labour government wanted to improve postwar UKRussia foreign relations) to copy them in a minimum of time. Stalin is said to have replied, "What fool will sell us his secrets?"
