The Lockheed S-3 Viking was a carrier-based, twin-engine jet aircraft developed for the United States Navy's anti-submarine mission and fleet surveillance. Its integrated crew and sensor suite replaced the slower S-2 Tracker with a faster, longer-legged platform, while later conversions extended the same family into electronic surveillance, tanker evaluation, and carrier logistics. The type first flew in 1972 and remained a defining U.S. Navy maritime aircraft for more than three decades.
