The F-111 Aardvark: Vietnam and Gulf War Warrior (and It Almost Killed Qaddafi)

Despite its flaws, it served its country honorably. 

The General Dynamics F-111 Aardvark was a low-altitude strike plane born out of a shotgun wedding between competing Air Force and Navy requirements—with Defense Secretary McNamara as the minister. Despite its troubled adolescence, it grew into a capable high-tech night bomber that lasted decades in service, noted for its sleekly elegant profile.

Troubled Conception

In the early 1960s, the Air Force came to realize that new, radar-guided surface-to-air missiles such as the Soviet SA-2 could reach its slow, high-altitude bombers. In response, it devised a new concept: a smaller long-range supersonic bomber that could skim close to the ground, below radar systems. At the same time, the U.S. Navy was looking for a fast, long-range carrier-based interceptor armed with air-to-air missiles that could take out Soviet bombers from a distance.

Newly appointed Defense Secretary Robert McNamara was convinced that a single aircraft could satisfy both requirements, thereby saving on development costs. The Army and Navy were less keen on compromising their visions, but were forced to cooperate on the so-called TFX program. A contract was awarded to General Dynamics in 1962. Because the design was smaller than Air Force strategic bombers, and the service eschewed the “attack” designation used by the Navy, it was designated with an “F” for fighter.

Revolutionary Design

The F-111 was built around two powerful yet fuel-efficient TF30 turbofan engines with new afterburner technology. A capacious fuselage could accommodate bomb loads of up to 31,000 pounds and fuel for missions up 2,500 miles long, with external tanks adding another 1,000 miles. The large plane weighed twenty tons empty—or more than twice that loaded.

The designers of the F-111 faced a challenge: they needed a plane that could fly at very high speeds, but still take off or land on a short runway. Using smaller wings would create less drag, allowing the aircraft to fly faster—but also create less lift, requiring the aircraft achieve higher speeds before it take off, in turn necessitating a longer runway. For example, the other supersonic fighter-bomber of the era, the F-105 Thunderchief, had very small wings—and required airstrips over a mile long for takeoff, limiting which airfields it could operate from.
