In 1974 the Lockheed S-3 Viking entered service with the USN as a twin-engine jet aircraft used for enemy submarine warfare. By the late 1990’s the role shifted to surface warfare providing the carrier battle group with long range surveillance capabilities and aerial refueling. The S-3 was in production from 1974 until 1978 with 186 (187) aircraft completed. Most airframes saw upgrades low pitch sound of the engines earned the S-3 the nickname “Hoover” after the vacuum cleaner.

After the retirement of the Lockheed S-3 Viking from frontline duty some aircraft were transferred to VX-30 “Bloodhounds”. One of the aircraft was Bu.No 159746 BH-702 c/n 3075 that had previously spent time with VS-22, VS-32 and VS41. The S-3B was used at Point Mugu, California for range clearance and surveillance of the 36,000 square mile Sea Range. Between 1971 and 1978 179 operational S-3 Vikings were manufactured and assigned to 18 Navy squadrons accumulating over 1.7 million flight hours.
