In its personnel carrier role, the C-130 can accommodate 92 combat troops or 64 fully equipped paratroops on side-facing seats. For medical evacuations, it carries 74 litter patients and two medical attendants. Paratroopers exit the aircraft through two doors on either side of the aircraft behind the landing-gear fairings. Another exit is off the rear ramp for airdrops.
The C-130 can deliver personnel, equipment or supplies either by landing or by various aerial delivery modes. Three primary methods of aerial delivery are used for equipment.
In the first, parachutes pull the load, weighing up to 42,000 pounds, from the aircraft. When the load is clear of the plane, cargo parachutes inflate and lower the load to the ground.
The second method, called the Container Delivery System, uses the force of gravity to pull from one to 16 bundles of supplies from the aircraft. When the bundles, weighing up to 2,200 pounds each, are out of the aircraft, parachutes inflate and lower them to the ground.
The Low Altitude Parachute Extraction System is the third aerial delivery method. With LAPES, up to 38,000 pounds of cargo is pulled from the aircraft by large, inflated cargo parachutes while the aircraft is five to 10 feet above the ground. The load then slides to a stop within a very short distance. Efforts are underway to increase the maximum load weights for LAPES aerial delivery to 42,000 pounds.
The C-130's design maximum gross weight is 155,000 pounds (175,000 pounds wartime) with a normal landing weight of 130,000 pounds. The operating weight is approximately 80,000 pounds. The airplane is capable of airlifting 92 ground troops, 64 fully equipped paratroopers, or 74 litter patients. It can also carry 45,000 pounds of cargo.
