The Lockheed C-130 Hercules is a multipurpose military transport aircraft used by many different nations around the world. This is a list of the specific military units, as well as some civilian airlines, that fly it.
88 MAG based at Lagos (C-130H, C-130H-30). On 26 September 1992 a NAF Lockheed C-130H Hercules serial number 911 crashed three minutes after take-off from Lagos, Nigeria when three engines failed possibly due to high take-off weight. All 158 people on board were killed, including 8 foreign nationals.
The Indian Air Force (IAF) inducted its first C-130J-30 Super Hercules on 5 February 2011. The remaining five on order were delivered by the end of 2011, and operated by 77 Squadron, the Veiled Vipers. On 3 October 2011 India announced its decision to buy six additional C-130J-30 Super Hercules with one more to replace the crashed aircraft taking the total to 12. The IAF has five C-130J-30s in service as of January 2016.
The Japan Defense Agency ordered the C-130H which was the newest model in 1981. The Japan Air Self-Defense Force (JASDF) purchased 16 in total to replace aging C-1 and YS-11P aircraft. The C-130Hs were received from 1984 to 1998.
JASDF C-130Hs were active in Iraq from 2004 to 2008. Two C-130Hs (95-1080 and 95-1083) have been equipped with aerial fuel-receiving and refueling functions, making them of KC-130H standard. This provides the JASDF with the ability to refuel the UH-60J search and rescue helicopters of its Air Rescue Wing.
The JMSDF bought six used KC-130R aircraft that were in storage, having been previously operated by the US Marines. There was some speculation that they may be used as gunships with the Harvest HAWK kit. In actuality they were purchased to replace three aging YS-11M/M-A aircraft of Air Transport Squadron 61.
Their air to air refueling equipment was removed, making them of C-130R standard. Corrosion repair was done and the aircraft were refitted with new landing gear supports, cargo door supports and center wing rainbow fittings. In addition to structural modifications, Japan received thirty overhauled T56-A-16 engines and digital cockpit upgrades to include a digital GPS. Regeneration of the first aircraft began in November 2012 and was planned to be completed by Fall 2013. The six C-130Rs were supplied from 2014 to 2016.

Sweden has operated eight C-130 aircraft (locally designated the Tp 84), originally delivered as C-130Es beginning in February 1965. They were upgraded to C-130H standard in the 1980s and are assigned to Skaraborg Air Force Wing (F 7), 3 Transportflygenhet based at Såtenäs. The first aircraft delivered as withdrawn from service on 9 June 2014, with the second scheduled to follow shortly.
All C-130 aircraft in Turkish service were to begin a 56-month upgrade by Turkish Aerospace Industries termed the Erciyes Program. Two are to be done directly at TAI while the remainder will be upgraded by the Air Force under TAI oversight. Primary aim of the upgrade is to improve the avionics with 17 new systems and five upgraded ones. Turkish content in both hardware and software has been increased to reduce long term costs.
