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 were lost through attrition, 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.
The Combat Shadows were built during the Vietnam War for search and rescue operations and repurposed in the 1980s as AFSOC air-refueling tankers; the last of the 24 retired in 2015.
The Combat Spear was developed in 2006 as an inexpensive version of the Combat Talon II but was reconfigured and designated the AC-130W Stinger II in 2012.
The MC-130J, which became operational in 2011, is the new-production variant that is replacing the other special operations MC-130s. As of 2023, the Air Force has taken delivery of 57 MC-130J models. The final MC-130J produced was delivered to USAF in January 2025.
MC-130E Combat Talon
Development The Combat Talon was developed between December 1964 and January 1967 by Lockheed Air Services (LAS) at Ontario, California, as the result of a study by Big Safari, the USAF's program office that modifies and sustains special mission aircraft. Two highly classified testbed aircraft (originally serial no. 64-0506 and -0507, but with all numbers "sanitized" from the aircraft), were assigned to Project Thin Slice to develop a low-level clandestine penetration aircraft for Special Forces operations in Southeast Asia. In 1964, Lockheed was ordered to adapt the C-130Es after six C-123B Providers modified for "unconventional warfare" under Project Duck Hook proved inadequate for the new MACV-SOG.Thigpen (2001), p. 20. The modifications under Thin Slice and its August 1966 successor Heavy Chain were code-named Rivet Yard,Rivet is the prefix designation for the names of all modification projects controlled by the Big Safari office, in this case its Detachment 4 at Ontario, California. and the four C-130Es came to be known as "Yards". Thigpen commanded the 8th SOS during Operation Just Cause and spent more than 10 years in the Combat Talon program. Discreet modification tests were conducted by the 1198th Operational Evaluation and Training Squadron, out of Area II of Norton AFB at San Bernardino, California, 30 miles east of Ontario.Olausson, Lars, Lockheed Hercules Production List – 1954–2008 – 25th ed., Såtenäs, Sweden, April 2007. Self-published. .Mueller, Robert, Air Force Bases Volume I – Active Air Force Bases Within the United States of America on 17 September 1982; Office of Air Force History, United States Air Force, Washington, DC, 1989, p. 447. .
As the Thin Slice aircraft were being developed, 14 C-130Es were purchased for SOG in 1965 for similar modification. The first aircraft were production C-130Es without specialized equipment that were produced at Lockheed's facility in Marietta, Georgia. Three production airplanes per month were given the Fulton STARS (then ARS) system. While awaiting the ARS equipment, the C-130s were ferried to Greenville, Texas, for painting by Ling-Temco-Vought Electrosystems with a low-radar reflective paint that added 168 kg (370 lbs) to their weight. The velvet black-and-green scheme drew the nickname "Blackbirds".Thigpen (2001), p. 58. That nickname lasted until the 1980s, when Dupont stopped manufacturing the paint. As installation was completed, the Blackbirds were returned to Ontario for installation of the electronics package, code-named Rivet Clamp. The modified aircraft became known as "Clamps" (two of the original 14, 64–0564 and -0565, were diverted to Heavy Chain in August 1966). The aircraft collectively were assigned the designation Combat Talon in 1967.Thigpen (2001), p. 88.
The Fulton surface-to-air recovery system was used to extract personnel and materials via air. A large helium balloon raised a nylon lift line into the air, which was snagged by a large scissors-shaped yoke attached to the nose of the plane. The yoke snagged the line and released the balloon, yanking the attached cargo off the ground with a shock less than that of an opening parachute. A sky anchor secured the line and wires stretched from the nose to both leading wing tip edges, protecting the propellers from the line on missed snag attempts. Crew members hooked the snagged line as it trailed behind and attached it to the hydraulic winch, pulling the attached person or cargo into the plane through the rear cargo door.
Following a death on 26 April 1982, at CFB Lahr, Germany,Thigpen (2001), pp. 261–262, Appendix A, p. 469. The Special Forces soldier suffered a punctured lung and broken hip in the short fall, but died of complications from a tracheotomy during medical evacuation. the Fulton STARS system on the Clamp aircraft underwent intense maintenance scrutiny and employment of the system for live pickups was suspended. A major effort at upgrading the system, Project 46,Thigpen (2001), p. 304. So-called because its objective was to develop a capability of extracting four to six troops in a single pass. was pursued from 1986 to 1989, but at its conclusion, use of the STARS system for live extractions remained suspended. The Fulton STARS equipment of all Combat Talons was removed during 1998.Thigpen (2001), p. 38.
Rivet Clamp installation began with four STARS-equipped C-130s completed by March 1966, followed by installations in eight further aircraft in July 1966 and January 1967. The Rivet Clamps, originally designated C-130E(I)sp, were equipped with an electronic and infrared (IR) countermeasures suite; and the SPR2 later the AN/APQ-115 TF/TA multimode radar. This radar, adapted from the Texas Instruments AN/APQ-99 radar used in the RF-4C Phantom photo reconnaissance aircraft, featured terrain following/terrain-avoidance (TF/TA) and mapping radar modes, to enable it to operate at low altitudes at night and in all weather conditions and avoid known enemy radar and anti-aircraft weapons concentrations.Thigpen (2001), p. 21. The 12 original C-130E(I) "Clamps" were 64–0523, -0547, -0551, -0555, -0558, -0559, -0561, -0562, -0563, -0566, -0567, and -0568.
Beginning in 1970, Texas Instruments and Lockheed Air Service worked to adapt the existing AN/APQ-122 Adverse Weather Aerial Delivery System (AWADS) with terrain following/terrain avoidance modes to replace the original AN/APQ-115, which suffered throughout its life with an unacceptably adverse Mean-Time-Between-Failure (MTBF) rate. In 1970 they succeeded, and coupled the AN/APQ-122 with the Litton LN-15J Inertial Navigation System (INS). Known as MOD-70, the modified radar was installed in all 12 operational Combat Talons and the four Heavy Chain test beds between 1971 and 1973. The system proved so successful that it continued in service until the late 1980s.Thigpen (2001), p. 66. Following the completion of MOD-70, the Combat Talons were divided into three designations: C-130E(CT) for the "Clamp" aircraft, C-130E(Y) for the "Yank" (formerly "Yard") Talons, and C-130E(S) for the "Swap".Thigpen (2001), p. 70. The "Swap" Talons were originally Rivet Clamp modifications without the Fulton STARS apparatus. The Combat Talon I designations were consolidated in 1977 as the MC-130 and have remained under that designation since.Thigpen (2001), p. 168. The Combat Talon became the Combat Talon I in 1984 with the authorization for the modification of 24 C-130Hs to Combat Talon II specifications.Thigpen (2001), P. 396.
The "Yank" Talons conducted top secret operations worldwide, under the project name Combat Sam, until late 1972. Two of the original "Clamps" were lost in combat in Southeast Asia and were replaced by two C-130Es (64-0571 and −0572). These remained as Combat Talons until 1972, when Heavy Chain was gradually discontinued and its four "Yank" aircraft were integrated into the Combat Talon force. The two original Thin Slice aircraft were given the serials of two destroyed C-130s, 62-1843 and 63-7785 respectively, to disguise their classified origins. The replacements had their modifications removed and returned to airlift duties, although known as "Swaps", they remained available for future Combat Talon use. Both eventually became Combat Talons again after further losses in the Combat Talon inventory.
Capability to act as a Forward Area Refueling Point (FARP) for helicopters on the ground was begun in 1980 in preparation for Operation Eagle Claw (see below), although only one system could be installed before the mission was executed. The refueling system consists of two palletized 6,800 L (1,800 gal) tanks (known as Benson tanks) mounted on rails within the Talon that tie into the C-130's own pressurized fuel dumping pumps and require no further equipment.Thigpen (2001), p. 237.
A major modification between 1986 and 1994, MOD-90, modernized the capability and serviceability of the Talon I to extend its service life. All 14 Combat Talon Is were equipped with upgraded navigational radars, an enhanced electronic warfare suite and provided new outer wings.Thigpen (2001), p. 473, lists all the changes. Other notable major upgrades were engine upgrade to Allison T56-A-15, new center wing boxes, installation of flare/chaff dispensers, infrared defensive pods, new FLIR, low gloss two-shade gray paint, the Universal Aerial Refueling Receptacle/Slipway, and Benson tanks for all aircraft. By 1995 all Combat Talon Is were equipped with helicopter-air refueling pods.Thigpen (2001), pp. 49 and 56.
Southeast Asia operations The aircraft received for modification as Combat Talons were assigned in July 1965 to the 464th Troop Carrier Wing at Pope Air Force Base, North Carolina. Because of a lack of ramp space caused by the buildup of forces for deployment to South Vietnam, they were temporarily housed at Sewart Air Force Base, Tennessee. The wing's 779th TCS was designated as the training squadron for the modified C-130E(I)s, under Project Skyhook, in addition to its normal airlift function. Selected crew members received instructor training in their respective systems and returned to Pope by 1 May to begin crew training of six crews for deployment to Vietnam under Project Stray Goose.
The Combat Talon I first saw operational action in the Vietnam War, beginning 1 September 1966. The six Stray Goose crews deployed to Ching Chuan Kang Air Base, Taiwan, and forward deployed to Nha Trang Air Base, South Vietnam. The deployment, known as Combat Spear, preceded operational deployment of other Combat Talons to Europe (Combat Arrow) and the United States (Combat Knife).
