Tanzania established its air force as the "Air Wing" (Kiswahili: "Usafirashaji wa Anga") of the TPDF Air Defence Command in 1965. As it was following an international policy of non-alignment, Tanzania procured aircraft and trainers from a variety of countries, most notably China, Canada, and the Soviet Union. By 1978, the Tanzanian Air Wing possessed 14 MiG-21MFs, two MiG-21UMs, 22 Shenyang J-5s (F-5), 12 Shenyang J-6s (F-6), as well as several transport and trainer aircraft. Furthermore, the country's Air Defence had access to SA-3 surface-to-air missiles, SA-7 MANPADS, 14.5mm and 36mm or 37mm anti-aircraft guns, and ground support equipment—including early-warning radars.
