From Wikipedia:

The Mikoyan-Gurevich MiG-17 (NATO reporting name: Fresco) is a transonic fighter aircraft produced in the Soviet Union from 1952 and was operated by air forces internationally. The MiG-17 was license-built in China as the Shenyang J-5 and Poland as the PZL-Mielec Lim-6. The MiG-17 is still being used by North Korea's air force in the present day and has seen combat in the Middle East and Asia.

It wasn't used in the Korean War, but it was used in the Vietnam War. The Soviet Union built 10,000 of them.
