The Lockheed S-3 Viking is a jet aircraft originally used by the United States Navy to identify, track, and destroy enemy submarines. In the late 1990s, the S-3B mission focus shifted from anti-submarine warfare to surface warfare and aerial refueling. After the retirement of the A-6 Intruder and A-7 Corsair II, the Viking was the only airborne refueling platform organic to the Carrier Air Wing(s) until the fielding of the F/A-18E/F Super Hornet.
It also provides electronic warfare and surface surveillance capabilities to the carrier battle group. A carrier-based, subsonic, all-weather, multi-mission aircraft with long range, it operates primarily with carrier battle groups as an in-flight tanker. It carries automated weapon systems, and is capable of extended missions with in-flight refueling.
