Before the MiG-15, B-29 bombers could raid North Korean cities at will — in broad daylight. After the introduction of the MiG-15, the bomber fleet was grounded because the Air Force's F-80 Shooting Stars were too slow to protect them. --- A strange, new plane was strafing American aircraft in the skies over the Korean War, and it [was 100 mph faster than anything the United Nations forces had in the air](). It was also killing dozens of UN pilots and planes — and it had to be stopped. It might be hard to believe, but the source of the Russians' new fighter's monstrous speed was a Rolls-Royce design, which was pretty much supplied by the British themselves. It wasn't very often that anyone pulled the wool over the eyes of the British during the Cold War. The Soviets were a clever bunch, though. In 1946, the Soviets were invited to a Rolls-Royce factory. The delegation in attendance included Artem Mikoyan (the man who put the 'Mi' in 'MiG') himself. Mikoyan was then invited to visit the house of a Rolls-Royce executive, where they played billiards. Artem Mikoyan was great at billiards. In fact, he may have used a textbook shark move, losing the first game and then raising the stakes on the second. Here's the bet he made: If the Russian wins, Rolls-Royce will have to sell jet engines to the Soviets. Find out who won at around 9:00 in the video below. If it sounds surprising that the deal was made over a bet or that the British would supply the Russians with Rolls-Royce engines, you're not alone. Stalin himself was incredulous, reportedly saying, "what idiot would sell us their jet engines?" The Russians agreed to use the acquired engines for non-military purposes exclusively, which they did... until they were able to make a Russian copy of the Rolls-Royce engines, then called the Klimov RD-45. The engine was fitted into the MiG-15 and was fully operational in time for the Korean War, taking to the skies with weaponry designed to take down B-29 Superfortress bombers. ![]() A B-29 Bomber in the gunsights of a MiG-15. It was the dominant fighter over Korea until the introduction of the American F-86 Sabre. The Sabre was more than a match for the new MiG, garnering a [10-to-1 combat victory ratio]() in the war. It was also the plane flown by all 39 United Nations fighter aces. Sabres and MiG-15s would be at each other's throats for the duration of the Korean War. The last Sabre was retired from the U.S. military in 1956 whereas the MiG-15 saw service around the world throughout the 1960s. In fact, the plane is still flying with the North Korean People's Air Force to this day. ## Author Blake Stilwell is We Are The Mighty's Editor-in-Chief, covering military news, entertainment, and history, along with veteran education, employment and entrepreneurship.
