Open in interactive gallery →

The General Dynamics F-111 Aardvark was a long-range, supersonic, all-weather strike aircraft and the world's first in-service variable-sweep-wing combat aircraft — a design innovation that allowed the same airframe to take off slowly from short fields, cruise efficiently at subsonic speeds, and dash to Mach 2.5 at high altitude with the wings fully swept back. Conceived in the early 1960s under Defense Secretary Robert McNamara's controversial TFX programme (a joint Air Force / Navy fighter project), the F-111 was originally meant to serve both U.S. Air Force low-altitude strike and U.S. Navy fleet defence roles in a single airframe. The Navy variant (F-111B) was cancelled as too heavy for carrier operations, but the Air Force F-111A entered service in 1967 and the type went on to become one of the most effective strike platforms of the Cold War.

The F-111's distinguishing features beyond the swing-wing were its side-by-side tandem cockpit (pilot left, weapon systems officer right) housed in an escape capsule rather than ejection seats — the entire crew compartment separated from the airframe by rocket motors and parachuted to a survivable landing — and its terrain-following radar, which automatically flew the aircraft 200 feet above the ground at 600 knots in zero visibility. Combined with internal weapons bays and 6,000-mile ferry range, the F-111 could deliver up to 31,500 lb of conventional or nuclear ordnance against targets deep inside the Warsaw Pact at altitudes too low for radar acquisition. The two Pratt & Whitney TF30-P-100 turbofans produced 25,100 lbf each with afterburner, propelling the 100,000 lb gross-weight aircraft to Mach 2.5 at altitude.

The Aardvark first saw combat in Vietnam during 1968's brief Combat Lancer deployment — a deployment marred by three losses to mechanical failure rather than enemy action — and returned in 1972's Linebacker II campaign with greatly improved reliability. Subsequent service included the 1986 Operation El Dorado Canyon strike on Libya (eighteen F-111Fs flew from RAF Lakenheath via Spain to bomb Tripoli, the longest fighter-bomber strike mission in history at that point), the 1991 Gulf War (F-111Fs and EF-111A Ravens flew over 4,000 sorties, including precision strikes against hardened bunkers and the destruction of Iraqi armour through GBU-28 "bunker buster" delivery), and Operation Desert Fox in 1998. A dedicated electronic-warfare derivative, the EF-111A Raven ("Spark Vark"), provided stand-off jamming for strike packages until its 1998 retirement.

The U.S. Air Force retired the F-111 in 1996 in favour of the F-15E Strike Eagle for theatre strike and the B-1B Lancer for deep penetration. The Royal Australian Air Force operated the export F-111C variant from 1973 until 2010 — the last Aardvarks in service anywhere — and ceremonially "dump-and-burn" demonstrations (igniting raw fuel from the dump pipe between the engine nozzles) became a fixture of Australian air shows. 563 airframes of all variants were produced between 1964 and 1976, and surviving examples are popular static displays at U.S. Air Force and RAAF museums.

For Kids — a shorter, friendlier version

The F-111 Aardvark was a 1960s American fighter-bomber. Pilots called it the "Aardvark" because of its long pointy nose. The F-111 had two big engines, swing wings (like the F-14 Tomcat), and could carry up to 31,500 pounds of bombs — almost as much as the much-bigger B-52. It was designed to fly low and fast through enemy radar.

The F-111 is about 73 feet long — much longer than a school bus. Top speed Mach 2.5 (about 1,650 mph) with the wings swept tight. Two crew members sit side-by-side in a sealed escape capsule — if they had to eject, the whole capsule shot out together (instead of separate seats), giving the crew more protection.

About 563 F-111s were built between 1964 and 1976. The Air Force used them through 1996. Australia bought 24 F-111s and used them until 2010. F-111s flew in the Vietnam War, the 1986 Libya strike, and the 1991 Gulf War.

The F-111's most-famous mission was the April 1986 strike on Libya. F-111s flew from England to Libya — a 13-hour mission requiring multiple in-flight refuelings. The mission proved the F-111's long range.

The F-111 retired in 1996 (American Air Force) and 2010 (Australia), replaced by F-15Es and Super Hornets.

Kids’ Questions

Why a sealed escape capsule?

Most fighter jets have ejection seats — each crew member sits in a seat that rockets out separately if they need to escape. The F-111 was different: the whole cockpit (containing both crew, both seats, food, water, oxygen, radio) sealed up and rocketed out together as a single capsule. It landed by parachute. The capsule could even float on water — crew members could survive inside until rescue. This was more complicated than separate ejection seats but kept the crew together. Only the F-111 (and the cancelled XB-70 Valkyrie) used this design.

Why was the F-111 called the Aardvark?

Pilots gave the F-111 the nickname "Aardvark" because of its long pointy nose. An aardvark is an African mammal with a long snout that uses its nose to dig for termites. The F-111's nose contained the radar and looked similar. The nickname stuck so well that the U.S. Air Force adopted it as the official name when the F-111 retired in 1996. Australian pilots called the F-111 the "Pig" for the same long-nose reason — both nicknames are about its unusual appearance.

Variants

F-111A
Initial 1967 USAF production variant. 158 built; saw service in Vietnam and was later upgraded for the EF-111A Raven electronic-warfare conversion.
F-111E / F-111F
European-theatre variants; the F-111F (1971) had the more powerful TF30-P-100 engines, AN/AVQ-26 Pave Tack laser designator pod, and was the most capable Aardvark — the type used in El Dorado Canyon and the 1991 Gulf War. 106 F-111E and 106 F-111F built.
FB-111A
SAC nuclear-strike variant for the long-range bomber force, 1968. Longer wings, increased fuel, B43/B61/B77 nuclear weapons or up to 12 SRAM stand-off missiles. 76 built; retired 1991 and either scrapped or converted to F-111G theatre-strike airframes.
EF-111A Raven
Electronic-warfare conversion of the F-111A by Grumman. Bulged tail-fin housing for the ALQ-99 jamming system, no offensive armament. "Spark Vark" supported every major USAF strike package from 1981 until 1998 retirement. 42 conversions.
F-111C / F-111G
F-111C was the export variant for the Royal Australian Air Force (24 aircraft, longer wings + heavier landing gear from FB-111A); F-111G was a theatre-strike conversion of surplus FB-111A airframes used briefly by USAF and Australia.

Notable Operators

United States Air Force
Operated F-111A/D/E/F, FB-111A, and EF-111A from 1967 to 1998 across TAC (theatre-strike command) and SAC (long-range bomber command). Combat over Vietnam, Libya (1986), Iraq (1991, 1998).
Royal Australian Air Force
Operated 24 F-111C airframes (later supplemented by ex-USAF F-111G) from 1973 to 2010. The longest-serving Aardvark fleet anywhere; based at RAAF Amberley with No. 1 and No. 6 Squadrons.

Frequently Asked Questions

Why is the F-111 called the Aardvark?

The nickname references the aircraft's long, drooping nose — visually reminiscent of the burrowing African mammal. "Aardvark" was unofficial throughout most of the F-111's USAF career and was officially adopted only on 27 July 1996 at the type's USAF retirement ceremony, the only formal naming in U.S. military aviation history to coincide with retirement. The Royal Australian Air Force used the official Australian name "Pig" — for similar reasons, plus the aircraft's habit of foraging at low altitude.

Was the F-111B Navy version ever built?

Yes, but it was cancelled before production. Seven F-111B prototypes were built by Grumman between 1965 and 1968 as the proposed Navy fleet-defence interceptor with the AWG-9 radar and AIM-54 Phoenix missile. The aircraft proved too heavy and too slow for carrier deck operations, and was cancelled in 1968. The AWG-9 / AIM-54 weapons system was successfully transplanted into the purpose-designed F-14 Tomcat, which became the Navy's actual fleet defender.

What was Operation El Dorado Canyon?

The 14–15 April 1986 U.S. retaliatory strike against Libya following the La Belle disco bombing in West Berlin. Eighteen F-111Fs of the 48th TFW (48th Fighter Wing) flew from RAF Lakenheath, England, around the Iberian Peninsula (France and Spain refused overflight) and across the Mediterranean to strike targets in Tripoli and Benghazi — a 14-hour, 6,400-mile round trip with multiple aerial refuellings. One F-111 was lost over the Mediterranean. It remained the longest fighter-bomber strike mission in history until the 2003 invasion of Iraq.

How did the F-111's escape capsule work?

Instead of conventional ejection seats, the entire two-seat cockpit was an integral capsule that separated from the fuselage on the pull of an ejection handle. Two rocket motors propelled the capsule clear of the aircraft, an extraction parachute deployed, and the capsule descended on a single main parachute with shock-attenuation airbags inflating beneath for landing. The system was self-righting and could float — providing crew survival in water as well as on land. It made the F-111 unique in U.S. fighter-bomber history; weight penalties prevented the design from being adopted on later types.

Why did the F-111 have such a bad early reputation?

The TFX programme was politically controversial from the start (Defense Secretary McNamara overrode Air Force and Navy preferences in awarding the contract), the Navy F-111B was cancelled as a failure, and the early F-111A's 1968 Vietnam debut saw three of six aircraft lost in five weeks to structural failures. The wing-pivot fitting required a complete redesign and retrofit programme, and reliability remained poor through 1970. The 1972 Linebacker II deployment with reworked aircraft proved the design's potential, but the early reputation lingered for decades (Air & Space Forces Magazine — TFX retrospective).

What replaced the F-111 in U.S. and Australian service?

The U.S. Air Force replaced the F-111 with the F-15E Strike Eagle (theatre strike), the B-1B Lancer (deep penetration), and the B-2 Spirit (stealthy long-range strike). Australia replaced the F-111C with the F/A-18F Super Hornet in 2010 as a transitional aircraft pending arrival of the F-35A from 2018.

Where can I see an F-111 today?

Major preserved examples are at the National Museum of the United States Air Force (Dayton, Ohio), the Imperial War Museum Duxford (UK), the Royal Australian Air Force Museum at Point Cook (Victoria), and the Aviation Heritage Centre at RAAF Amberley (Queensland). The RAAF buried 23 retired F-111Cs in a sealed pit at the Ipswich, Queensland landfill in 2011 — the airframes contained asbestos sealant from period manufacture and could not economically be decontaminated for sale.
