History of the Development of the General Dynamics F-111 Aardvark

Context and Epoch: The Cold War period, particularly the 1960s, was characterized by a rapid arms race between the U.S. and the Soviet Union. Military strategists emphasized the need for a versatile aircraft capable of delivering nuclear ordnance at high speeds and over long distances.

Need and Objective: The U.S. Department of Defense sought a multirole aircraft that could operate both as a tactical strike aircraft and an air superiority fighter, resulting in the Tactical Fighter Experimental (TFX) program. This initiative aimed to produce an aircraft that would serve both the Air Force and Navy, embodying the concept of “commonality”. The F-111 emerged from this program, with General Dynamics being awarded the contract in 1962.

Design of the General Dynamics F-111 Aardvark

Technical Information:

  • Wingspan: 63 feet (spread) / 32 feet (swept) which is approximately 19.2 meters (spread) / 9.75 meters (swept).
  • Length: 73.6 feet or 22.4 meters.
  • Max Takeoff Weight: 100,000 pounds or around 45,360 kilograms.
  • Engines: Two Pratt & Whitney TF30-P-100 turbofans.


  • Variable Geometry Wings: Allowed the aircraft to optimize performance across a broad range of speeds and altitudes.
  • Terrain Following Radar: Provided the F-111 with the ability to fly at extremely low altitudes at high speeds, avoiding enemy radar and anti-aircraft fire.
  • Escape Capsule: Instead of traditional ejection seats, the Aardvark featured an escape capsule that could eject both crew members in a protected environment.


  • Initial design issues, particularly with the wing-carry through box and engine inlets, led to cost overruns and delays.
  • The F-111’s design did not meet the Navy’s needs, resulting in the service withdrawing from the program.

Performance of the General Dynamics F-111 Aardvark

Engine & Power: Powered by its twin TF30-P-100 turbofans, the aircraft produced 25,100 pounds of afterburning thrust per engine.

Speed: Maximum speed of Mach 2.5 or around 1,650 mph (2,655 km/h).

Altitude & Range: Operational ceiling of 66,000 feet (20,100 meters) and a range of 3,700 miles (5,955 kilometers) with external tanks.

Comparison: When pitted against contemporary designs like the Soviet Sukhoi Su-24 “Fencer”, the F-111 boasted superior electronics and avionics, albeit at a higher cost. Its long range and ability to carry a diverse weapon payload made it unmatched in deep strike capabilities.

Military Use and Combat of the General Dynamics F-111 Aardvark

Armament: Primarily armed with a mixture of air-to-ground ordnance, including general-purpose bombs, cluster bombs, and laser-guided munitions. It was also capable of carrying the AGM-69 SRAM nuclear missile.

Combat Operations of the General Dynamics F-111 Aardvark

Vietnam War

As the U.S. escalated its involvement in the Vietnam War during the late 1960s, the need for a fast, precise bomber capable of delivering accurate strikes under the cover of night became evident. The F-111 was an answer to this requirement. Introduced into the theater in 1968, the Aardvark, particularly the F-111A variant, played a pivotal role in the Operation Linebacker campaigns, targeting North Vietnamese infrastructure.

Equipped with innovative avionics, the F-111 could navigate and deliver its payload with a level of accuracy previously unseen, minimizing collateral damage. Its ability to fly at low altitudes at high speeds, thanks to its terrain-following radar, allowed it to evade enemy anti-aircraft defenses effectively. Over the course of the war, the Aardvark conducted hundreds of sorties, primarily at night, to reduce exposure to enemy ground fire.

Operation Eldorado Canyon (1986)

The U.S. response to terrorist activities tied to Libya culminated in Operation Eldorado Canyon in 1986. One of the most audacious and longest fighter missions of its time, F-111Fs, along with EF-111A Ravens for electronic warfare support, were dispatched from RAF Lakenheath in England to strike multiple targets in Libya.

Navigating a path that skirted hostile nations and covered a distance of over 6,400 miles (round trip), the F-111s were a testament to the importance of strategic planning, in-flight refueling capabilities, and the jet’s own long-range attributes. Targets included airbases, terrorist training camps, and infrastructure tied to Libyan leader Muammar Gaddafi. The operation, while controversial, underscored the F-111’s unique ability to deliver decisive strikes thousands of miles away from its base.

Gulf War (1991)

With the onset of the Gulf War in 1991, the F-111 once again demonstrated its prowess, this time in the deserts of Iraq. Re-designated as the F-111E and F-111F for this conflict, these aircraft were instrumental in Operation Desert Storm, the massive coalition air campaign against Saddam Hussein’s forces.

Employing the latest in precision-guided munitions, such as the GBU-15 and GBU-12 laser-guided bombs, Aardvarks targeted key Iraqi infrastructure, including power plants, communication facilities, and bridges. Their missions also aimed at reducing Iraq’s capability to wage war, targeting weapons storage facilities, and airbases. The jet’s unique side-by-side seating arrangement, with both a pilot and weapons system officer, allowed for effective coordination in deploying these advanced weapons.

With the backdrop of night vision technology and advanced avionics, the F-111 was often at the forefront of nighttime operations, crippling Iraq’s war-waging capability and setting the stage for the rapid ground campaign that followed. Their effectiveness in these missions only further highlighted the aircraft’s evolution from its troubled inception to a key asset in modern warfare.

Foreign Sales: Australia was the only foreign operator, where the aircraft, known as the F-111C, served with distinction.

Operational Conclusion: The U.S. retired the F-111 in the 1990s, with the F-15E Strike Eagle largely assuming its roles. Australia continued operations until 2010, before transitioning to newer platforms.

The General Dynamics F-111 Aardvark, while born out of a contentious developmental phase, eventually showcased its worth as a premier strike platform. Its adaptability, innovative design, and combat prowess have solidified its place in aviation annals. The F-111 stands as a testament to the blend of strategic foresight and engineering prowess, a true embodiment of its era.
