One Airframe, Many Jobs: Transport, Spy Plane, Gunship and Multirole Fighter

The Hercules entered United States Air Force service in 1956 as a four-engine turboprop transport, and more than 2,700 have been built for over sixty nations. Its value lay in reliability and short-field performance, and its adaptable airframe was later built into gunship, aerial refueling and search-and-rescue variants.

Where the Hercules is slow and sturdy, the Blackbird was built to outrun trouble. It entered service in January 1966 as a Mach 3 class reconnaissance aircraft, and only 32 were built. It was targeted by roughly 800 surface-to-air missiles without ever being shot down.

The gunship shows how far one airframe can be pushed. The cargo hold of a C-130 was replaced with cannons fired out of the left side while the aircraft circled a fixed point on the ground. The first model flew in 1967, and its slow, low profile is why it flies most close air support missions after dark.

Jointly developed by Britain, West Germany and Italy, the Tornado first flew in August 1974 and entered service around 1979. It was designed for high-speed, low-level penetration of air defenses and built as strike, interceptor and electronic-warfare variants, with 745 of the IDS strike version produced.

Sweden asked for a light fighter that could operate from short or damaged roads under its wartime dispersal doctrine. The Gripen entered Swedish service in 1996 and its JAS designation covers the fighter, attack and reconnaissance roles in one single-engine aircraft.

The Rafale was designed from the outset as a multirole aircraft. Dassault prefers the word omnirole, since one airframe can be configured for air superiority, ground attack, reconnaissance, anti-ship strikes and, in French service, nuclear deterrence. It was introduced in 2001.

China's delta-wing, canard fighter first flew in March 1998 and joined the People's Liberation Army Air Force in the mid-2000s. More than 600 had been built by the mid-2020s, and Pakistan became its first export customer from 2022.

The Su-34 grew out of the Su-27 air-superiority fighter but became a two-seat fighter-bomber, with a side-by-side cockpit for long missions and up to roughly 12,000 kilograms of ordnance on twelve hardpoints. It first flew in 1990 yet only entered official Russian service in 2014.
