Lockheed Martin KC-130

The Lockheed Martin (previously Lockheed) KC-130 is a family of the extended-range tanker version of the C-130 Hercules transport aircraft. The KC-130J is the latest variant operated by the United States Marine Corps (USMC), with 48 delivered out of 79 ordered. It replaced older KC-130F, KC-130R, and KC-130T variants for aerial refueling. USMC reserve unit, VMGR-452 operated 12 KC-130T aircraft until May 2021; this was the last USMC reserve unit that operated the legacy KC-130s, completing the Corps' transition to the more advanced Super Hercules.

The KC-130F made its first test flight in January 1960 as the GV-1 under the old Navy designation system. First entering service in 1962, the KC-130F was designed to undertake aerial refueling missions in support of USMC aircraft. It was developed from the Lockheed C-130 Hercules.

The newest Hercules, the KC-130J, shares 55 percent of the same airframe as preceding models, but in fact is a greatly improved airplane. It is based on the Lockheed Martin C-130J Super Hercules and provides significant increases in operational capability and performance margins over preceding KC-130F/R/T (legacy) aircraft. Additionally, The KC-130J reduces cost of ownership through system reliability and reduced maintenance man-hours per flight hour.

The new HC-130J combat rescue tanker and MC-130J special operations tanker are both derived from a KC-130J baseline.

Technological development has led to the incorporation of interior/exterior night vision lighting, night vision goggle head-up displays, global positioning system, and jam-resistant radios. Some KC-130s are also equipped with defensive electronic and infrared countermeasures systems.

The KC-130 is a multi-role, multi-mission tactical tanker/transport which provides the refueling support required by the USMC for its aircraft. This versatile asset provides in-flight refueling to both tactical aircraft and helicopters within a 500-nautical-mile (930 km) operating radius, as well as rapid ground refueling when required. Additional tasks performed are aerial delivery of troops and cargo, emergency resupply into unimproved landing zones within the objective or battle area, emergency medical evacuation, tactical insertion of combat troops and equipment, and evacuation missions.

The KC-130J offers a 27,215 kg (60,000 lb) fuel capacity that it can allocate between its own flight requirements against aerial refueling offload capacity using its wing and external tanks while in the air. When more fuel is needed, an additional 11,064 kg (24,392 lb) of fuel can be offloaded from a specially configured internal fuselage 13,627 L (3,600-gallon) aluminum fuel tank. The system also functions without the fuselage tank, so the cargo compartment can be used for cargo on the same mission, giving the aircraft even greater flexibility.

The aircraft is ready to fuel fixed-wing, tilt-rotor, or rotary-wing aircraft using the standard probe and drogue technique. The two wing-mounted hose and drogue refueling pods (made by Sargent Fletcher) can each transfer up to 300 gallons (1,136 L) per minute to two aircraft simultaneously, allowing for rapid cycle times of multiple-receiver aircraft formations, a typical tanker formation of four aircraft in less than 30 minutes.
