The C-130 Hercules is the workhorse of the RAF transport fleet. Over the years it has proved to be a versatile and rugged aircraft, primarily intended for tactical operations including troop carrying, paratrooping, supply dropping and aeromedical duties.

The Hercules can operate from short unprepared airstrips, but also possesses the endurance to mount long-range strategic lifts if required.

As a troop carrier, the Hercules can carry 92 fully armed men, while for airborne operations 64 paratroops can be dispatched in two simultaneous 'sticks' through the fuselage side doors. Alternatively, 40 paratroops can jump from the rear loading ramp. As an air ambulance the aircraft can accommodate 74 stretchers. Freight loads that can be parachuted from the aircraft include: 16 x 1 ton containers or 4 x 8,000 pound platforms or 2 x 16,000 pound platforms or 1 x platform of 30,000 pounds plus. 

Amongst the many combinations of military loads that can be carried in an air-landed operation are: 3 x Ferret scout cars plus 30 passengers or 2 x Land Rovers and 30 passengers or 2 x Gazelle helicopters.

Of the original 66 C1 aircraft, some 31 have been given a fuselage stretch producing the Mark C3. The C3 'stretched version' provides an additional 37% more cargo space. Refuelling probes have been fitted above the cockpit of both variants and some have received radar warning pods under the wing tips. One aircraft, designated Mark W2, is a special weather version and is located at the DRA Farnborough.

Hercules C-130J C4/C5

The RAF has replaced some of its Hercules C1/C3 aircraft with second-generation C-130Js on a one-for-one basis. Twenty-five Hercules C4 and C5 aircraft were ordered in December 94, and the first entered service in 2000 – two years behind schedule. Deliveries were completed by 2003 at a total cost of just over £1bn.The C4 is the same size as the older Hercules C3 which features a fuselage lengthened by 4.57 m (15ft) than the original C1. 
 

The Hercules C5 is the new equivalent of the shorter model. With a flight deck crew of two plus one loadmaster, the C-130J can carry up to 128 infantry, 92 paratroops, 8 pallets or 24 CDS bundles. The Hercules C4/C5s have new Allison turboprop engines, R391 6-bladed composite propellers and a Full Authority Digital Engine Control (FADEC). This propulsion system increases take-off thrust by 29% and is 15% more efficient. Consequently, there is no longer a requirement for the external tanks to be fitted. An entirely revised 'glass' flight deck with head-up displays (HUD) and four multi-function displays (MFD) replacing many of the dials of the original aircraft. These displays are compatible with night-vision goggles (NVG).
