Libya began building a modern and integrated air defense system in the mid-1970s. They imported large numbered radars, surface-to-air missiles, communication and other related equipment were imported from the Soviet Union.
The USSR delivered 39 S-75 Volhov and 44 S-125 Neva anti-aircraft missile battalions between 1974 and 1985 to the Libyan Air Defense. As planned, these forces are defending the large Libyan cities, like Tripoli, Misurata, Sirte, Benghazi, and Tobruk along the Mediterranean coast. Thousands of Soviet advisers helped build the new integrated air defense system.
