During the Korean War in the 1950’s, MiG-15bis began to appear in the skies over Korea and quickly proved superior to straight-wing American jets such as the F-80 and F-84 Thunderjet. The MiG- 15 temporarily gave the Chinese the advantage in the air and ultimately forced United Nations forces to halt daylight bombing.MiG Alley: The MiG-15's arrival compelled the US Air Force to begin deploying the new F- 86 Sabre to Korea. Arriving on the scene, the Sabre restored balance to the air war. In comparison, the F-86 could out dive and out turn the MiG-15, but was inferior in rate of climb, ceiling, and acceleration. Though the Sabre was a more stable gun platform, the MiG-15's
all-cannon armament was more effective than the American aircraft's six .50 cal. machine guns. In addition, the MiG benefited from the rugged construction typical of Russian aircraft which made it difficult to bring down.The most famous engagements involving the MiG-15 and F-86 occurred over northwestern North Korea in an area known a "MiG Alley." In this area, Sabres and MiGs frequently dueled, making it the birthplace of jet vs. jet aerial combat. Throughout the conflict, many MiG-15s were covertly flown by experienced Soviet pilots. When encountering American opposition, these pilots often were evenly matched. As many of the American pilots were veterans of World War II, they tended to have the upper hand when facing MiGs flown by North Korean or Chinese pilots.
