In general, the Lockheed C-130 Hercules is a highly reliable aircraft: the Royal Air Force (RAF) recorded an accident rate of about one aircraft loss per 250,000 flying hours over the last forty years, making it one of the safest aircraft they operate.United States Air Force Hercules (A/B/E-models), as of 1989, had an overall attrition rate of 5 percent as compared to 1 to 2 percent for commercial airliners in the U.S., according to the NTSB, 10 percent for B-52 bombers, and 20 percent for fighters (F-4, F-111), trainers (T-37, T-38), and helicopters (H-3).
More than 15 percent of the approximately 2,350 production hulls have been lost, including 70 by the US Air Force and the United States Marine Corps during the Vietnam War. Not all US C-130 losses have been crashes, 29 of those listed below were destroyed on the ground by enemy action or other non-flying accidents. This is thought to be a complete listing through July 1, 2012, but omits the JC-130A (53-3130, c/n 3002) test airframe that was tested to destruction and airframes retired or withdrawn from service. By the nature of the Hercules' worldwide service, the pattern of losses provides a barometer of global hotspots over the past fifty years.
The two prototype YC-130s, AF Serial Numbers 53-3396 and 53-3397, were built at the Burbank, California plant, and were given c/ns 1001 and 1002. Production Hercules have all been built at the Lockheed-Marietta, Georgia plant, and began their c/ns at 3001 (USAF 53-3129, still extant at the Air Force Armament Museum). The first prototype, c/n 1001, was disassembled at Warner Robins AFB in October 1960. The second prototype, c/n 1002, was salvaged at Indianapolis, Indiana in April 1962. (Lars Olausson, Lockheed Hercules Production List, 1954–2008, April 2007, page 2.) There have been a small number of c/ns assigned to airframes on order that were not built for various reasons. Also, C-130A model production ended at c/n 3231, and a new series for the B-model began at c/n 3501, the only time a large block was skipped for an upgraded airframe.
