The Lockheed MC-130 is the basic designation for a family of special mission aircraft operated by the United States Air Force Special Operations Command (AFSOC), a wing of the Air Education and Training Command, and an AFSOC-gained wing of the Air Force Reserve Command. Based on the Lockheed C-130 Hercules transport, the MC-130s' missions are the infiltration, exfiltration, and resupply of special operations forces, and the air refueling of (primarily) special operations helicopter and tilt-rotor aircraft.
The first of the variants, the MC-130E, was developed to support clandestine special operations missions during the Vietnam War. Eighteen were created by modifying C-130E transports, and four lost through attrition,[citation needed] but the remainder served more than four decades after their initial modification. An update, the MC-130H Combat Talon II, was developed in the 1980s from the C-130H and went into service in the 1990s. Four of the original 24 H-series aircraft have been lost in operations.
