Lockheed S-3 Viking

The Lockheed S-3 Viking is a four-seat, twin engine aircraft, that was used by the US Navy for anti submarine warfare and aerial refueling. The Viking also provided electronic warfare and surface surveillance. It’s a carrier based, subsonic, all-weather, multi-mission aircraft with long range; it carried automated weapon systems, and was capable of extended missions with mid air refueling ability. ecause of the Viking’s engines’ characteristic sound, it was nicknamed the “Hoover” after the vacuum cleaner brand.

The S-3 Viking is the only Navy aircraft to ever wear the callsign “Navy One” when in President Bush flew in the Co-pilot seat onboard the USS Abraham Lincoln.

NASA Viking
One aircraft was transformed into a state-of-the-art NASA research aircraft. The Navy’s Fleet Readiness Center – Southeast and a Boeing facility in Florida enhanced the plane by adding commercial satellite communications, global positioning navigation and weather radar systems. They installed research equipment racks in what was once the plane’s bomb bay. NASA’s S-3B Viking is equipped to conduct science and aeronautics missions, such as environmental monitoring, satellite communications testing and aviation safety research
