Osprey's study of the use of MiG-21 Units in the Vietnam War (1955-1975). Having honed their piloting skills on the subsonic MiG-17 and transonic MiG-19, the Vietnamese Peoples' Air Force (VPAF) received their first examples of the legendary MiG-21 supersonic fighter in 1966. Soon thrown into combat over North Vietnam, the guided-missile equipped MiG-21 proved a deadly opponent for the USAF, Navy and Marine Corps crews striking at targets deep into communist territory. Most of the VPAF's 12+ aces scored their bulk of their kills in the MiG-21, which was then the best fighter produced by Russia's premier fast jet manufacturer, Mikoyan Gurevich. Well over 200 MiG-21s were supplied to the VPAF, and the numerous models and the schemes they wore are chronicled in great detail in this unique volume.
