The Lockheed C-130 Hercules is a military cargo plane, famed for its rugged quad-engine turboprop design and ability to use unpaved runways. Originally designed as a transport for infantry and heavy cargo, the C-130 has gone on to prove itself in a wide range of roles, including aerial assault, search and rescue, weather studies, mid-air refuelling and use as a seaborne patrol aircraft. The aircraft’s principal operators include the US Air Force (USAF), US Marine Corps and Britain’s Royal Air Force, but variants of the Hercules are currently serving in over 60 different countries. The C-130 has been in continuous production since 1954, and currently holds the record for the longest production run of a military plane or helicopter. Over 2,300 have been built, at a cost of $62 million per unit. It also holds the record for the heaviest aircraft to successfully land on an aircraft carrier.
Over 40 different variants of the C-130 have been produced, a testament to the versatility of its airframe. In its regular guise as a heavy lifter and troop transport, the C-130 can take a 45,000 pound (20,000 kg) payload inside its 40 foot cargo hold. In real terms, this could work out to 92 standard passengers, 64 airborne troops, six pallets, three Humvees or two M113 APCs. The aircraft is powered by four Allison T56-A-15 turboprop engines, each producing 4,590 shp of power, and can cruise at 292 knots with a range of 2,050 nautical miles.
The Hercules was conceived in the early 1950s as a replacement for the piston-engined transport planes that were in common use at the time. The USAF made its requirement known to many prominent aircraft manufacturers of the day, and was submitted designs from Boeing, Douglas, Airlifts Inc., Chase and Lockheed. The Air Force were impressed with the prototype C-130 they were shown, especially its custom designed T56 turboprop engines, which produced a fair higher power-to-weight ratio than contemporary piston engines. Lockheed won the contract, and delivered the USAF’s first Hercules planes in 1956. The first non-American force to operate the aircraft was the Royal Australian Air Force, which began running the Hercules in 1958.

The Lockheed Martin / Boeing F-22 Raptor is a fifth-generation fighter jet, currently in service with the United States Air Force (USAF). It is notable for being the first fifth-generation fighter to reach active service, as well as the USAF’s first supermaneuverable production aircraft. Concieved as an aerial superiority fighter, the F-22 incorporates stealth technology to increase battlefield survivability, and can also take on electronic warfare and surface strike roles if required. It was principally built by Lockheed Martin, with Boeing acting as a secondary contractor to provide part of the plane’s airframe and on board systems. Production ended in 2011 to make way for the forthcoming F-35 Lightning II.
The F-22 is powered by twin Pratt and Whitney F119 turbofan engines, each generating 23,500 pounds of thrust. This figure increases to over 35,000 pounds with afterburner engaged, and gives the Raptor a supercruise speed of Mach 1.82. The aircraft has a range of over 1,600 nautical miles, which can be extended to 1,840 with the addition of external fuel tanks. It is armed with a 20mm M61A2 Vulcan gatling cannon, and has four hardpoints under its wings. Most of the F-22’s armament is stored inside the fuselage of the aircraft in an effort to improve its stealth characteristics. It can be fitted with either air-to-air missiles, including the AIM-9 Sidewinder and AIM-120 AMRAAM, or small bombs such as the JDAM or GBU-39. The hardpoints can be used to increase weapons loadout or to carry 600 gallon external drop tanks.
The Raptor is currently only operated by the USAF, due in no small part to US Congress placing a ban on all F-22 exports. The Japanese government has expressed an interest in using the aircraft in its Replacement-Fighter program, but as of 2013 no move has been forthcoming. Congress, the Pentagon and the State Department would all need to ratify the sale if it were to go ahead.
195 Raptors were produced between 1996 and 2011, including eight test aircraft. With a cost per unit of $150 million, the total F-22 program is estimated to have cost around $66.7 billion. The aircraft’s cost was a major factor in the decision to end the Raptor program, as the replacement F-35 is a considerably cheaper option.
