Made famous by the Vietnam War, the MiG-17 was the primary enemy aircraft engaged in the skies over Vietnam by U.S. aircraft such as the A-4, A-7, F-8, B-52, F-100, F-105, and its primary nemesis, the F-4 Phantom II. During that war and until the F-16 entered service, it was the tightest-turning fighter in the world. When production started in the 1950s, its VK-1F engine made it one of the first production jet fighters in the world with an afterburner. The MiG-17 used one 7,452-pound-thrust Klimov VK-1F turbojet engine, had an empty weight of 8,064 pounds and a maximum takeoff weight of 13,393 pounds, a wingspan of 31 feet 7.25 inches, a length of 36 feet 11.25 inches, a height of 12 feet 5.5 inches, a maximum speed of 711 miles per hour at 10,000 feet, a ceiling of 54,460 feet, a range of 1,230 miles, and armament of one 37-millimeter N-37 cannon, two or three 23-millimeter NR-23 cannon, and up to 1,100 pounds of mixed stores on underwing hard-points. More than 9,000 were built, including more than 6,000 in the USSR alone.
