Britain's Gift To The Soviets | When Rolls Royce Gave The Jet Engine To Russia, And They Copied It

In 1951, a Mikoyan-Gurevich MiG-15 was shot down over Korea's west coast and plummeted into the Yellow Sea.
The jet was pulled from the shallow water by US and South Korean forces and transported by a British frigate for study.
At a US Air Force base in Dayton, Ohio, the plane is poured over. 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 Rolls-Royce Neen II, designed in England.
The Mikoyan-Gurevich MiG-15 (Russian: Микоян-Гуревич МиГ-15; USAF/DoD designation: Type 14; NATO reporting name: Fagot) is a jet fighter aircraft developed by Mikoyan-Gurevich for the Soviet Union. The MiG-15 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 straight-winged jet day fighters, which were largely relegated to ground-attack roles. In response to the MiG-15's appearance and in order to counter it, the United States Air Force rushed the North American F-86 Sabre to Korea.
When refined into the more advanced MiG-17, the basic design would again surprise the West when it proved effective against supersonic fighters such as the Republic F-105 Thunderchief and McDonnell Douglas F-4 Phantom II in the Vietnam War of the 1960s.
The MiG-15 is believed to be one of the most produced jet aircraft, with more than 13,000 manufactured. The MiG-15 remains in service with the Korean People's Army Air Force as an advanced trainer.
The first turbojet fighter developed by Mikoyan-Gurevich OKB was the Mikoyan-Gurevich MiG-9, which appeared in the years immediately after World War II. It used a pair of reverse-engineered German BMW 003 engines. The MiG-9 was a troublesome design that suffered from weak, unreliable engines and control problems. Categorized as a first-generation jet fighter, it was designed with the straight-style wings common to piston-engined fighters.

In 1946 Soviet engine technology was far behind the West's. The Germans had been unable to develop airworthy turbojets with thrust over 1,130 kilograms-force (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 Rolls-Royce Nene (having been alerted to the fact that the U.K. Labour government wanted to improve post-war UK-Russia foreign relations) for the purpose of copying them in a minimum of time. Stalin is said to have replied, "What fool will sell us his secrets?"
