Lockheed S-3B Viking

The Viking was designed in the late 1960s to replace the aging S-2 Tracker as the Navy’s carrier based, fixed wing anti-submarine aircraft. Incorporating the latest electronic and acoustic submarine hunting technology in an airframe powered by two highly efficient turbofan engines the S-3A greatly increased the Navy’s ability to locate and track Soviet nuclear submarines. The first Viking flew in January 1972 and so impressed the Navy that the first production contract was issued only three months later. Anti-submarine squadron 21 was the first to use the Viking operationally in 1974. The aircraft proved to be extremely safe, reliable, and versatile. In 1981, Lockheed began upgrading the existing Vikings to incorporate newer electronic systems and the ability to fire the Harpoon anti-ship missile.
