The General Dynamics F-111 Aardvark is a retired supersonic, medium-range, multirole combat aircraft. Production models of the F-111 had roles that included attack (e.g. interdiction), strategic bombing (including nuclear weapons capabilities), reconnaissance and electronic warfare. Aardvark comes from a South African animal that has a long nose and hugs the terrain. It is an Afrikaans word that translates literally as "earth pig"—hence the aircraft's "Pig" nickname during its Australian service.
Developed in the 1960s by General Dynamics under Robert McNamara's TFX Program, the F-111 pioneered variable-sweep wings, afterburning turbofan engines, and automated terrain-following radar for low-level, high-speed flight. Its design influenced later variable-sweep wing aircraft, and some of its advanced features have become commonplace. The F-111 suffered problems during initial development, largely related to the engines. A fighter variant intended for the United States Navy, the F-111B, was canceled before production; it was intended for aircraft carrier-based roles, including long-range interception. Several specialized models, such as the FB-111A strategic bomber and the EF-111A electronic warfare aircraft, were also developed.
The F-111 entered service in 1967 with the United States Air Force (USAF). The Royal Australian Air Force (RAAF) also ordered the F-111 and began operating the F-111C in 1973. As early as March 1968, the USAF were deploying F-111s into active combat situations; the type saw heavy use during the latter half of the Vietnam War to conduct low-level ground-attack missions, flying in excess of 4,000 combat missions while incurring only six combat losses in the theatre. The F-111s also participated in the Gulf War (Operation Desert Storm) in 1991; the F-111Fs completed 3.2 successful strike missions for every unsuccessful one, better than any other US strike aircraft used in the operation. RAAF F-111s never saw offensive action, but were deployed periodically as a deterrent, such as for the Australian-led International Force East Timor.
Being relatively expensive to maintain amid post-Cold War budget cuts, the USAF elected to retire its F-111 fleet during the 1990s; the last F-111Fs were withdrawn in 1996 while the remaining EF-111s also departed in 1998. The F-111 was replaced in USAF service by the McDonnell Douglas F-15E Strike Eagle for medium-range precision strike missions, while the supersonic bomber role has been assumed by the B-1B Lancer. The RAAF continued to operate the type up until December 2010, when the last F-111C was retired; its role was transitioned to the Boeing F/A-18E/F Super Hornet as an interim measure until the Lockheed Martin F-35 Lightning II became available.
Development
=Early requirements=
The May 1960 U-2 incident, in which an American CIA U-2 reconnaissance plane was shot down over the USSR, stunned the United States government. Besides greatly damaging US–Soviet relations, the incident showed that the Soviet Union had developed a surface-to-air missile that could reach aircraft above 60,000 feet (18,000 meters). Consequently, the United States Air Force Strategic Air Command (SAC) and the RAF Bomber Command's plans to send subsonic, high-altitude Boeing B-47 Stratojet and V bomber formations into the USSR were realized to be much less viable.Lax 2010, p. 15.
By 1960, SAC had begun moving to low-level penetration, which greatly reduced radar detection distances. At the time, SAMs were ineffective against low-flying aircraft while interceptor aircraft had less of a speed advantage at low altitudes.Spick 1986, pp. 4–7. The USAF's Tactical Air Command (TAC) was largely concerned with the fighter-bomber and deep strike/interdiction roles. TAC was in the process of receiving its latest design, the Republic F-105 Thunderchief, which was designed to deliver nuclear weapons fast and far, but required long runways.Gunston 1978, pp. 12–13. A simpler variable geometry wing configuration with the pivot points farther out from the aircraft's centerline was reported by NASA in 1958, which made swing-wings viable.Thomason 1998, pp. 5–6.Davies 2013, pp. 6-7. This led USAF leaders to encourage its use.Miller 1982, pp. 10–11.
In June 1960, the USAF issued specification SOR 183 for a long-range interdiction/strike aircraft able to penetrate Soviet air defenses at very low altitudes and high speeds.{{Sfn|Gunston|1978|pp= 12–13, 16}} Specifically, it was to be capable of at least {{cvt|800|mi|km}} of low-level flight, {{cvt|400|mi|km}} of which was to be at a speed of no less than Mach 1.2.Knaack 1978, p. 223. Furthermore, the specification also called for the aircraft to possess short takeoff and landing (STOL) capabilities to permit operations from short, unprepared airstrips that had a length of no more than {{convert|3000|ft|m|sigfig=1}}. An internal payload of {{convert|1000|lb|kg}} was to be carried in the primary mission role. A variant suitable for aerial reconnaissance flights was also included in the specification.Knaack 1978, pp. 223-224.
In the 1950s, the United States Navy sought a long-range, high-endurance interceptor aircraft to protect its carrier battle groups against long-range anti-ship missiles launched from Soviet jet bombers and submarines. The Navy needed a fleet air defense (FAD) fighter with a more powerful radar, and longer range missiles than the F-4 Phantom II to intercept both enemy bombers and missiles.Thomason 1998, pp. 3–5.Davies 2013, p. 7. Seeking a FAD fighter, the Navy started with the subsonic, straight-winged aircraft, the Douglas F6D Missileer in the late 1950s. The Missileer was designed to carry six long-range missiles and loiter for five hours, but would be defenseless after firing its missiles.{{Sfn|Gunston|1978|p= 13}} The program was formally canceled in 1961. The Navy had tried variable geometry wings with the XF10F Jaguar, but abandoned it in the early 1950s.Davies 2013, p. 6. It was NASA's simplification which made the variable geometry wings practical. By 1960, increases in aircraft weights required improved high-lift devices, such as variable geometry wings.{{Sfn|Gunston|1978|pp= 11–12}}Miller 1982, p. 11. Variable geometry offered high speeds, and maneuverability with heavier payloads, long range, and the ability to take off and land in shorter distances.{{Sfn|Gunston|1978|pp=11–12}}
=Tactical Fighter Experimental (TFX)=
The USAF and Navy were both seeking new aircraft when Robert McNamara was appointed secretary of defense in January 1961.Miller 1982, p. 13. Both sought high-supersonic, twin-engine, two-seat aircraft that could carry heavy armament and fuel loads and probably use variable geometry wings.{{Sfn|Gunston|1978|p= 16}}Davies 2013, p. 4. On 14 February 1961, McNamara formally directed the services to study the development of a single aircraft that would satisfy both requirements. Early studies indicated that the best option was to base the design on the USAF requirement, and use a modified version for the Navy.{{Sfn|Gunston|1978|pp=8–17}} In June 1961, Secretary McNamara ordered the go-ahead of Tactical Fighter Experimental (TFX), despite USAF and Navy efforts to keep their programs separate.{{Sfn|Eden|2004|pp=196–7}}{{cite news |url= https://news.google.com/newspapers?id=o-VVAAAAIBAJ&sjid=EuEDAAAAIBAJ&pg=6856%2C3575947|work= Eugene Register-Guard |location= Oregon, US |agency= Associated Press |last= Price |first= Bem |title= Capital still buzzing whether TFX a colossal blunder |date= 18 September 1966 |page= 5A}} According to aviation author Peter E. Davis, military officials were disconcerted by McNamara's focus on compromised requirements for financial reasons.Davies 2013, pp. 4-5.
File:General Dynamics F-111A cockpit 061003-F-1234S-015.jpg
The two services could agree only on swing-wing, two-seat, twin-engine design features. The USAF wanted a tandem-seat aircraft for low-level penetration ground-attack, while the Navy wanted a shorter, high altitude interceptor with side-by-side seating to allow the pilot and radar operator to share the radar display.{{Sfn|Gunston|1978|pp=8–17}}Knaack 1978, p. 224. Also, the USAF wanted the aircraft designed for 7.33 g with Mach 2.5 speed at altitude and Mach 1.2 speed at low level with an approximate length of {{convert|70|ft|m|sigfig=3|abbr=on}}. The Navy had less strenuous requirements: 6 g with Mach 2 speed at altitude and high subsonic speed (about Mach 0.9) at low level with a length of {{convert|56|ft|m|sigfig=3|abbr=on}}. The Navy also wanted the aircraft with a nose large enough for a {{convert|48|in|m|sigfig=2|abbr=on|adj=on}} diameter radar dish.{{Sfn|Gunston|1978|pp=8–17}}Miller 1982, pp. 11–15.
McNamara developed a basic set of requirements for TFX based largely on the USAF's requirements and, on 1 September 1961, ordered the USAF to develop it.{{Sfn|Gunston|1978|pp= 8–17}} Nevertheless, a request for proposals (RFP) for the TFX was provided to industry in October 1961.Knaack 1978, pp. 224-225. In December, proposals were received from Boeing, General Dynamics, Lockheed, McDonnell, North American and Republic. The evaluation group found all the proposals lacking, but Boeing and General Dynamics were selected to submit enhanced designs.Knaack 1978, p. 225. Boeing's proposal was recommended by the selection board in January 1962, with the exception of the engine, which was not considered acceptable. The board also directed alterations to radar and missile storage and a switch from ejection seats to a crew escape capsule. Both companies provided updated proposals in April 1962. USAF reviewers favored Boeing's offering, while the Navy found both submissions unacceptable for its operations. Two more rounds of updates to the proposals were conducted, and the board eventually recommended the Boeing design.{{Sfn|Gunston|1978|pp=18–20}}
But in November 1962, McNamara selected General Dynamics' proposal due to its greater commonality between USAF and Navy versions. The Boeing aircraft shared less than half of the major structural components. On 21 December 1962, General Dynamics signed the TFX contract.Knaack 1978, pp. 225-226. A congressional investigation into the procurement processed was conducted, but did not change the selection.{{Sfn|Gunston|1978|pp=18–20}}{{cite news |url= https://news.google.com/newspapers?id=StoxAAAAIBAJ&pg=2650%2C6893340 |work= Reading Eagle |location= Pennsylvania, US |agency= Associated Press |title= F-111 problems return to plague President |date= 13 January 1970 |page= 8}} On 1 May 1964, the definitized contract was issued for the program, including flight testing, spares, ground equipment, training devices, static and fatigue test data, and the production of an initial 23 F-111 aircraft; it was structured as a fixed price incentive fee (FPIF) contract with a ceiling price of $529 million along with provisions for deficiency correction amongst other operational clauses and performance criteria.Knaack 1978, p. 226.
=Design phase=
General Dynamics' design team was led by Robert H. Widmer.{{cite news |last= Martin |first= Douglas |url= https://www.nytimes.com/2011/07/03/business/03widmer.html?_r=1&ref=deathsobituaries |title= Obituary: Robert H. Widmer, Designer of Military Aircraft, Dies at 95 |newspaper= The New York Times |date= 2 July 2011}} Recognizing its lack of experience with carrier-based fighters, General Dynamics teamed with Grumman in November 1963 for the assembly and testing of the F-111B. In addition, Grumman would also build the aft fuselage and the landing gear of the F-111A.Knaack 1978, p. 236. The General Dynamics and Grumman team faced ambitious requirements for range, weapons load, and aircraft weight.Thomason 1998, pp. 9–10. Thus, the F-111 was designed to incorporate numerous features that were new to production military aircraft, such as variable-geometry wings and afterburning turbofan engines.Miller 1982, pp. 17, 19. This use of unfamiliar features has been attributed as a major cause of the aircraft's protracted development and weight increases.Davies 2013, p. 5.
The F-111A and F-111B shared the same airframe structural components and Pratt & Whitney TF30-P-1 turbofan engines. They featured side-by-side crew seating in an escape capsule as required by the Navy. The F-111B's nose was {{convert|8.5|ft|m|sigfig=3|sp=us}} shorter as the aircraft could fit on existing carrier elevator decks, and had {{convert|3.5|ft|m|sigfig=3|adj=mid|-longer}} wingtips to improve on-station endurance time; it also carried an AN/AWG-9 Pulse-Doppler radar to guide its AIM-54 Phoenix missiles. The USAF's F-111A would be equipped with the AN/APQ-113 attack radar and the AN/APQ-110 terrain-following radar and air-to-ground armament.Baugher, Joe. [http://www.joebaugher.com/usaf_fighters/f111_1.html "General Dynamics F-111A."] USAAC/USAAF/USAF Fighters, 23 December 1999. Retrieved: 5 October 2009.
During September 1963, the F-111A mockup was inspected. On 15 October 1964, the first test F-111A was rolled out of Plant 4 of General Dynamics' facility in Fort Worth, Texas; it was powered by YTF30-P-1 turbofans and used a set of ejector seats as the escape capsule was not yet available. On 21 December 1964, the F-111A made its first flight from Carswell Air Force Base, Texas.{{Sfn|Eden|2004|p=197}} Lasting for 22 minutes, less than planned due to a flap malfunction, this initial flight was considered to be satisfactory overall; category I testing commenced immediately thereafter.Knaack 1978, pp. 226-227.{{cite news |url= https://news.google.com/newspapers?id=qzhWAAAAIBAJ&sjid=wOgDAAAAIBAJ&pg=2676%2C1891540 |work= Spokesman-Review |location= Spokane, Washington, US |agency= Associated Press |title= Controversial TFX test flight is success |date= 22 December 1964 |page= 1}} Early flights of the F-111, which included supersonic flights, demonstrated favorably simplistic maintenance requirements, amongst other qualities.Knaack 1978, p. 227.
Various changes to the program were enacted throughout 1965; this was chiefly in response to a steep climb in unit costs from $4.5 million to $6 million. The cause of the cost rises has been attributed, at least partially, to a directive issued to General Dynamics to incorporate improved avionics as well as to work on strategic bomber and aerial reconnaissance variants of the aircraft, the latter of which was eventually cancelled. During April 1965, General Dynamics was authorized to produce 431 F-111s, less than half the number of aircraft which had originally been forecast.Knaack 1978, pp. 227, 233. On 10 May 1967, a new multi-year FPIP contract replaced the prior procurement process, increasing the total aircraft on order to 493 F-111s of multiple models, including 23 F-111Bs intended for the US Navy, 24 F-111Cs for the Royal Australian Air Force, and 50 F-111Ks intended for the Royal Air Force.Knaack 1978, p. 228.
Early flights of the F-111 were troubled by compressor surges and stalls across certain portions of the flight regime.Knaack 1978, pp. 227-228. General Dynamics had elected to use an uncommon spike-shaped variable intake for the engine for the performance. Studies performed by NASA, the USAF, and General Dynamics led to the engine inlet being redesigned; modifications were implemented between 1965 and 1966, culminating with the "Triple Plow I" and "Triple Plow II" designs.Gunston 1978, pp. 25–27.{{cite web |title= F-111 |url= https://fas.org/man/dod-101/sys/ac/f-111.htm |website= FAS.org |publisher= Federation of American Scientists |date= 24 December 1998 |access-date= 15 August 2014}}Knaack 1978, pp. 228-229. During February 1965, the F-111A achieved a speed of Mach 1.3 while flying with an interim intake design. On 18 May 1965, the F-111B made its first flight; it was also equipped with ejector seats initially.Baugher, Joe. [http://www.joebaugher.com/usaf_fighters/f111_4.html "General Dynamics/Grumman F-111B."] USAAC/USAAF/USAF Fighters, 7 November 2004. Retrieved: 5 October 2009.Thomason 1998, pp. 16, 20.
Separately, cracks in the F-111's wing attach points were first discovered in 1968 during ground fatigue testing; during the following year, the crash of an F-111 was attributed to a cracked wingbox.Knaack 1978, p. 234. On 22 December 1969, the USAF opted to ground the fleet due to this issue, save for those involved in flight testing.Knaack 1978, pp. 230-231. The resolution involved the redesigning of the attach structure and necessitated testing to ensure adequate design and workmanship.Miller 1982, pp. 31, 47. On 31 July 1970, the grounding was lifted.Knaack 1978, p. 231. Category I flight testing of the F-111A, which had started in 1964, continued through to 31 March 1972.Logan 1998, p. 32. Category II tests started in January 1966, while Category III testing was repeatedly postponed before being cancelled, having been deemed to be unnecessary.
During 1968, the F-111B was canceled by the Navy on account of weight and performance issues together with revised tactical requirements.{{Sfn|Boyne|2002|p=252}}Thomason 1998, pp. 52–53. Australia would procure its own model, the F-111C. Subsequently, the improved F-111E, F-111D, and F-111F models were developed for the USAF. The strategic bomber FB-111A and the EF-111 electronic warfare versions were later developed for the USAF.{{Sfn|Frawley|2002|p= 89}} Production of the F-111 ended in 1976,Miller 1982, p. 65. following the completion of 563 aircraft.
Design
=Overview=
File:F-111A Wing Sweep Sequence.jpg
The F-111 was an all-weather attack aircraft, capable of low-level penetration of enemy defenses to deliver ordnance on the target.[http://www.nationalmuseum.af.mil/factsheets/factsheet.asp?id=2322 "General Dynamics F-111D to F Aardvark."] {{webarchive|url=https://web.archive.org/web/20100531135621/http://www.nationalmuseum.af.mil/factsheets/factsheet.asp?id=2322 |date=31 May 2010}} US Air Force National Museum. Retrieved: 3 December 2010. The F-111 featured variable-geometry wings, an internal weapons bay and a cockpit with side-by-side seating. The cockpit was part of an escape crew capsule.Eden 2004, pp. 196–201. The wing sweep varied between 16 degrees and 72.5 degrees (full forward to full sweep). The wing included leading edge slats and double slotted flaps over its full length.Miller 1982, pp. 80–81. The airframe was made up mostly of aluminum alloys with steel, titanium and other materials used in places.Logan 1998, pp. 17–18.Davies 2013, pp. 20-21. The fuselage was made of a semi-monocoque structure with stiffened panels and honeycomb structure panels for skin. The horizontal stabilizer was an all-moving stabilator.{{cite web |title=General Dynamics F-111 |url=http://www.airvectors.net/avf111.html |website=www.airvectors.net |access-date=18 October 2022}}Davies 2013, p. 8.
The F-111 used a three-point landing gear arrangement, with a two-wheel nose gear and two single-wheel main landing gear units. The landing gear door for the main gear, which was positioned in the center of the fuselage, also served as a speed brake in flight.Logan 1998, p. 19. Most F-111 variants included a terrain-following radar system connected to the autopilot. The aircraft was powered by two Pratt & Whitney TF30 afterburning turbofan engines. The F-111's variable-geometry wings, escape capsule, terrain following radar and afterburning turbofans were new technologies for production aircraft.Logan 1998, p. 14.
=Armament=
20 mm cannon and 5,000 lb of bombs internal – pylons can carry up to 25,000 lb of bombs or two nuclear weapons internal and four AGM-69 SRAM nuclear weapons external.{{cn|date=May 2025}}
== Weapons bay ==
The F-111 featured an internal weapons bay that could carry bombs, a removable 20 mm M61 cannon or auxiliary fuel tanks.Logan 1998, pp. 20, 21, 28. For bombs, the bay could hold two 750 lb (340 kg) M117 conventional bombs, one nuclear bomb or practice bombs. The F-111B for the US Navy was to carry two AIM-54 Phoenix long-range air-to-air missiles in the bay. The cannon had a large 2,084-round ammunition tank, and its muzzle was covered by a fairing; however, it was rarely fitted on F-111s.Gunston 1983, p. 30.
The F-111C and F-111F were equipped to carry the AN/AVQ-26 Pave Tack targeting system on a rotating carriage that kept the pod protected within the weapons bay when not in use. Pave Tack featured a forward looking infrared (FLIR) sensor, optical camera and laser rangefinder/designator. The Pave Tack pod allowed the F-111 to designate targets and drop laser-guided bombs on them.Logan 1998, pp. 29–30. Australian RF-111Cs carried a pallet of sensors and cameras for aerial reconnaissance use.Miller 1982, p. 31.
The FB-111 could carry two AGM-69 SRAM air-to-surface nuclear missiles in its weapons bay.Gunston 1983, p. 31. General Dynamics trialed an arrangement with two AIM-9 Sidewinder air-to-air missiles carried on rails in a trapeze arrangement from the bay, but this was not adopted. Early F-111 models had radars equipped to guide the AIM-7 Sparrow medium-range air-to-air missile, but it was never fitted.Gunston 1983, pp. 23–24.
== External ordnance ==
File:F-111 with Durandal.jpg concrete penetration bombs|alt=Closeup view of cylindrical bombs and ordnance carried under a mostly green aircraft wing]]
Each wing was equipped with four underwing pylons. The inner two pylons on each wing rotated to align with the fuselage, while the outer two were fixed. Each pylon had a capacity of {{convert|5000|lb|kg|abbr=off|sigfig=2}}. Various bombs and missiles could be carried on the pylons. Auxiliary fuel drop tanks with {{convert|600|USgal|L|abbr=off|sigfig=2}} capacity each could be fitted.Gunston 1983, pp. 30–31.
The design of the F-111's fuselage prevented the carriage of external weapons under the fuselage, but two stations were available on the underside for electronic countermeasures (ECM) pods or datalink pods; one station was on the weapons bay, and the other on the rear fuselage between the engines. The F-111's maximum practical weapons load was limited, since the fixed pylons could not be used with the wings fully swept.Logan 1998, p. 18.
Tactical F-111s were fitted with shoulder rails on the four inner swiveling pylons to mount AIM-9 Sidewinder air-to-air missiles for self-defense. Australian F-111Cs were equipped to launch the Harpoon anti-ship missile, and the Popeye stand-off missile.Logan 1998, p. 28. FB-111As could carry the same conventional ordnance as the tactical variants, but their wing pylons were more commonly used for either fuel tanks or strategic nuclear gravity bombs. They could carry up to four AGM-69 SRAM nuclear missiles on the pylons.Gunston 1983, p. 49.
=Historical significance=
The F-111 was the first production variable-geometry wing aircraft. Several other types have followed with similar swing-wing configuration, including the Soviet Sukhoi Su-17 "Fitter" (1965), Mikoyan-Gurevich MiG-23 "Flogger" (1967), Tupolev Tu-22M "Backfire" (1969), Sukhoi Su-24 "Fencer" (1970) and Tupolev Tu-160 "Blackjack" (1981); the US Rockwell B-1 Lancer bomber (1974); and the European Panavia Tornado (1974). The Sukhoi Su-24 was very similar to the F-111.Gunston 1983, p. 3. The US Navy's role intended for the F-111B was instead filled by another variable-geometry design, the Grumman F-14 Tomcat.
Operational history
=US Air Force=
File:F-111As Combat Lancer 1968.jpg
The first of six initial production F-111s was delivered on 17 July 1967 to fighter squadrons at Nellis Air Force Base.Gunston 1983, p. 32.Logan 1998, p. 33. These aircraft were used for crew training. 428th Tactical Fighter Squadron achieved initial operational capability on 28 April 1968.Knaack 1978, p. 229.
After early testing, a detachment of six aircraft from the 474th Tactical Fighter Wing (474th TFW Roadrunners) were sent in March 1968 to Southeast Asia for Combat Lancer testing in real combat conditions in the Vietnam War.Knaack 1978, pp. 229-230. During the deployment, 55 night missions were flown against targets in North Vietnam, but two aircraft had been lost. 66–0022 was lost on 28 March, and 66-0017 on 30 March. Replacement aircraft left Nellis, but the loss of a third F-111A (66-0024) on 22 April halted F-111A combat operations. The squadron returned to the United States in November. The cause of the first two losses is unknown as the wreckages were never recovered. It turned out that the third loss was traced to a failure of a hydraulic control-valve rod for the horizontal stabilizer which caused the aircraft to pitch up uncontrollably. Further inspection of the remaining fleet of F-111As revealed 42 aircraft with the same potential failures.Davies and Thornborough 1997, pp. 40, 43. It is speculated that this failure could also have contributed to the two earlier losses had the failure caused a pitch down while at low altitude. It was not until 1971 that 474 TFW was fully operational.Thornborough and Davies 1989, p. 34.
The word "aardvark" is Afrikaans for "earthpig" and reflects the look of the long nose of the aircraft that might remind one of the nose of the aardvark. The origin of the name has been attributed to F-111A Instructor Pilot Al Mateczun in 1969, as the aircraft had not received an official USAF name.Thornborough and Davies 1989, p. 33.
During September 1972, the F-111 returned to Southeast Asia, stationed at Takhli Air Base, Thailand.Knaack 1978, pp. 231-232. F-111As from Nellis AFB participated in the final month of Operation Linebacker and later flew 154 low-level missions in the Operation Linebacker II aerial offensive against the North Vietnamese, who called the aircraft "Whispering Death".{{Cite web |url= https://www.thedrive.com/the-war-zone/4595/flying-the-iconic-swing-wing-f-111-aardvark-at-the-height-of-the-cold-war |title= Flying the Iconic Swing-Wing F-111 Aardvark at the Height of the Cold War |last1= Crandall |first1= Richard |last2= Rogoway |first2= Tyler |date= 27 July 2016 |website= The Drive |access-date= 31 October 2019}} They also supported regional aerial operations against other communist forces such as Operation Phou Phiang III during the Laotian Civil War in Laos.Thornborough and Davies 1989, p. 37.

One F-111 could carry the bomb load of four McDonnell Douglas F-4 Phantom IIs. The worth of the new aircraft was beginning to show; F-111s flew more than 4,000 combat missions in Vietnam with only six combat losses.Logan 1998, pp. 283–284.Knaack 1978, p. 232.
From 30 July 1973, F-111As of the 347th Tactical Fighter Wing (347th TFW) were stationed at Takhli Air Base. The 347th TFW conducted bombing missions in Cambodia in support of Khmer Republic forces until 15 August 1973 when US combat support ceased in accordance with the Case–Church Amendment.{{cite web |url=http://www.gpo.gov/fdsys/pkg/STATUTE-87/pdf/STATUTE-87-Pg130.pdf |title=Public law 93-52 aka the Case-Church Amendment |date=1 July 1973 |access-date=25 November 2013}} The 347th TFW was stationed at Korat Royal Thai Air Force Base from 12 July 1974 until 30 June 1975.

Variants
=F-111A=
The F-111A was the initial production version of the F-111. Early A-models used the TF30-P-1 engine. Most A-models used the TF30-P-3 engine with 12,000 lbf (53 kN) dry and 18,500 lbf (82 kN) afterburning thrust and "Triple Plow I" variable intakes, providing a maximum speed of Mach 2.3 (1,450 mph, 2,300 km/h) at altitude.Miller 1982, pp. 26, 66. The variant had a maximum takeoff weight of {{convert|92500|lb|kg|sigfig=3|abbr=on}} and an empty weight of {{convert|45200|lb|kg|sigfig=3|abbr=on}}.Logan 1998, p. 302.
The F-111A's Mark I avionics suite included the General Electric AN/APQ-113 attack radar mated to a separate Texas Instruments AN/APQ-110 terrain-following radar lower in the nose and a Litton AJQ-20 inertial navigation and nav/attack system. The terrain-following radar (TFR) was integrated into the automatic flight control system, allowing for "hands-off" flight at high speeds and low levels (down to {{cvt|200|ft|m|0|disp=or}}).Gunston 1978, pp. 46–47.
A total of 159 F-111As were produced, including 30 pre-production aircraft that were rebuilt to production standards.{{cite web |title=F-111 Production List |url=http://www.f-111.net/downloads/acftdata.pdf |website=F-111.net |access-date=13 June 2020 |archive-date=15 December 2007 |archive-url=https://web.archive.org/web/20071215102837/http://www.f-111.net/downloads/acftdata.pdf |url-status=dead}}Miller 1982, p. 26. 42 F-111As were converted to EF-111A Ravens for an electronic warfare tactical electronic jamming role.Logan 1998, p. 92. In 1982, four surviving F-111As were provided to Australia as attrition replacements and modified to F-111C standard, including its longer-span wings and reinforced landing gear.Logan 1998, p. 263. Three pre-production F-111A were used by NASA for various tests. The 13th F-111A received new wing designs for the Transonic Aircraft Technology and Advanced Fighter Technology Integration programs in the 1970s and 1980s.Logan 1998, pp. 289–293. It retired to the United States Air Force Museum at Wright-Patterson Air Force Base in 1989. Unconverted F-111As were mothballed at Aerospace Maintenance and Regeneration Center at Davis-Monthan Air Force Base in June 1991.Logan 1998, p. 48.

File:F-111B CVA-43 approach July1968.jpg
The F-111B was to be a fleet air defense (FAD) fighter for the US Navy, fulfilling a requirement for a carrier-based fighter aircraft armed with heavy, long-range missiles to defend aircraft carriers and their battle groups from Soviet bombers and fighter-bombers equipped with anti-ship missiles. General Dynamics, lacking experience with carrier-based aircraft, partnered with Grumman for this version. Seven F-111Bs were completed for testing but it never entered fleet service.Knaack 1978, p. 237. It had a troubled development and Navy requirements changed to a maneuverable aircraft for dogfighting. The swing-wing configuration, TF-30 engines, AIM-54 Phoenix air-to-air missiles and AWG-9 radar developed for the F-111B were used on its replacement, the Grumman F-14 Tomcat. The Tomcat was large enough to carry the AWG-9 and Phoenix missiles while exceeding both the F-111's and the F-4's maneuverability.Thomason 1998, p. 54.

The F-111C is the export version for Australia, combining the F-111A with longer F-111B wings and strengthened FB-111A landing gear.Knaack 1978, p. 233. Australia ordered 24 F-111s and, following delays, the Royal Australian Air Force accepted the aircraft in 1973.Logan 1998, p. 261. Four were converted to the RF-111C reconnaissance variant in 1979–80. Australia also purchased four ex-USAF F-111As and converted them into F-111Cs.{{cite web |url=http://www.boeing.com/global/Australia/BAL/DIVAerospaceSupport/f111.html |title=F/RF-111C Modifications and Support |publisher=Boeing Australia |access-date=3 July 2009 |archive-url=https://web.archive.org/web/20050427163959/http://www.boeing.com/global/Australia/BAL/DIVAerospaceSupport/f111.html |archive-date=27 April 2005 |url-status=dead |date=27 April 2005}}
In the 1990s, the F-111C underwent a comprehensive digital avionics upgrade program (AUP) which introduced new nav/attack systems (PAVE TACK Laser/infrared targeting system) and digital flight control computers.{{cite web |url= http://www.f-111.net/CarloKopp/aup.htm |title=F-111 Aardvark - New Tusks for the Pig |website=www.f-111.net |access-date=20 September 2018 |archive-date=29 September 2018 |archive-url=https://web.archive.org/web/20180929122903/http://www.f-111.net/CarloKopp/aup.htm |url-status=dead}} Later, the C model was upgraded with a unique version of the TF-30 engine known as the P-108.

=F-111D=
The F-111D was an upgraded F-111A equipped with newer Mark II avionics, more powerful engines, improved intake geometry, and an early glass cockpit.Davies 2013, pp. 38-39.Knaack 1978, pp. 249-250. It was first ordered in 1967 and delivered from 1970–73 after delays due to avionics issues.Knaack 1978, pp. 252-253. The F-111D reached initial operational capability in 1972; the sole operator was the 27th TFW stationed at Cannon AFB, New Mexico. 96 were built.Logan 1998, pp. 26, 106–107.
The F-111D used the new Triple Plow II intakes, which were located four inches (100 mm) further away from the airframe to prevent engine ingestion of the sluggish boundary layer air that was known to cause stalls in the TF30 turbofans. It had more powerful TF30-P-9 engines with 12,000 lbf (53 kN) dry and 18,500 lbf (82 kN) afterburning thrust.Knaack 1978, pp. 250–252.
The Mark II avionics used digitally integrated microprocessors, some of the first used by the USAF, offering new capability but substantial problems.Knaack 1978, p. 253-255. The Rockwell Autonetics digital bombing-navigation system included an inertial navigation system, AN/APQ-130 attack radar system, Doppler radar, digital computer set, and multi-function displays (MFDs). The terrain-following radar was the Sperry AN/APQ-128.Logan 1998, pp. 26–27. The attack radar featured a Doppler beam-sharpening, moving target indication (MTI), and Continuous-wave radar for guiding semi-active radar homing missiles.Gunston 1978, pp. 94–95. Avionics reliability improved but some issues were never fully resolved; according to Crandall, "The truth is that the D model didn't work. They parked every single one of them in Fort Worth for several years as they worked to fix the bugs". The F-111D was withdrawn from service in 1991 and 1992.Logan 1998, p. 108.
=F-111E=
A simplified, interim variant ordered after the F-111D was delayed, the F-111E used the Triple Plow II intakes, but retained the F-111A's TF30-P-3 engines and Mark I avionics.Gunston 1978, pp. 74–76.Davies 2013, p. 39. The weapon stores management system was improved and other small changes made.Miller 1982, p. 32. Crandall described the F-111E as "all analog, just like the A model, but It worked".{{r|thedrive20160727}}
The F-111E was first ordered in 1968. Its first flight occurred on 20 August 1969 and achieved initial operational capability late that year.Logan 1998, pp. 137–138.Knaack 1978, p. 238. 94 F-111Es were delivered between 1969 and 1971. Many F-111Es were assigned to the 20th TFW at Upper Heyford, UK until 1991.Knaack 1978, p. 239. It saw action during the Gulf War. Some F-111Es received an Avionics Modernization Program and improved TF30-P-109 engines in the early 1990s. All were retired to AMARC by 1995.Logan 1998, p. 138.
=F-111F=
The F-111F was the final variant produced for Tactical Air Command, with a modern, but less expensive, Mark IIB avionics system, more powerful TF30-P-100 engine, and strengthened wing carry-through box.Gunston 1978, pp. 95–97.Knaack 1978, p. 256. Crandall described it as "the Cadillac of the F-111 force".{{r|thedrive20160727}} The USAF approved its development in 1969. 106 F-111Fs were produced between 1970 and 1976.Logan 1998, pp. 169–171.Davies 2013, pp. 39-40.
The F-111F could reach Mach 1.2 at sea level on full afterburner.{{cite web |last1= Sherman |first1= Robert |title= F-111 - Military Aircraft |url= https://fas.org/man/dod-101/sys/ac/f-111.htm |publisher= Federation of American Scientists |access-date= 26 May 2021 |date= 2 November 2016}} It had the Triple Plow II intakes along with the substantially more powerful TF30-P-100 turbofan with 25,100 lbf (112 kN) afterburning thrust, 35% more thrust than the F-111A and E. An adjustable engine nozzle was added to decrease drag. The P-100 engine greatly improved performance.Gunston 1978, p. 96.Knaack 1978, p. 257. The engines were upgraded to the TF30-P-109 version between 1985 and 1986.Logan 1998, p. 301.
The F-111F's Mark IIB avionics suite used a simplified version of the FB-111A's AN/APQ-144 radar, which lacked some operating modes but added a new 2.5 mi (4.0 km) display ring. Although tested with digital moving-target indicator (MTI) capacity, it was not used in production sets. The Mark IIB avionics combined some Mark II components with FB-111A components, such as the AN/APQ-146 terrain-following radar. The F-111E's weapon management system was also included.Logan 1998, pp. 27, 169. In the early 1980s, the F-111F began to be equipped with the AVQ-26 Pave Tack forward looking infrared (FLIR) and laser designator system, which enabled the use of precision laser-guided munitions and was mounted in the internal weapons bay.[http://www.flightglobal.com/pdfarchive/view/1982/1982%20-%200080.html "Pave Tack operational on European F-111s."] Flight International, 9 January 1982.{{r|thedrive20160727}} The Pacer Strike avionics update program replaced analog equipment with new digital equipment and multi-function displays.Logan 1998, pp. 28–29. The last USAF F-111s were withdrawn from service in 1996, replaced by the McDonnell Douglas F-15E Strike Eagle.[http://nl.newsbank.com/nl-search/we/Archives?p_product=ST&s_site=dfw&p_multi=ST&p_theme=realcities&p_action=search&p_maxdocs=200&p_topdoc=1&p_text_direct-0=0EAF909C3B4ED340&p_field_direct-0=document_id&p_perpage=10&p_sort=YMD_date:D&s_trackval=GooglePM "F-111's builders and fliers to gather for retirement."] Fort Worth Star-Telegram, 25 July 1996.

{{main|General Dynamics F-111K}}
The British government canceled the BAC TSR-2 strike aircraft in 1965, citing the lower costs for the TFX and ordered 50 F-111K aircraft in February 1967 for the Royal Air Force.Gunston 1978, pp. 84–87. The F-111K was to be supplemented later by the Anglo-French Variable Geometry Aircraft then under development. The F-111K was based on the F-111A with longer F-111B wings, FB-111 landing gear, Mark II navigation/fire control system, and British supplied mission systems. Other changes included weapons bay modifications, addition of a centerline pylon, a retractable refueling probe, provisions for a reconnaissance pallet, and a higher gross weight with the use of FB-111A landing gear.Logan 1998, pp. 278–80.Davies 2013, pp. 40-41.
In January 1968, the United Kingdom terminated its F-111K order, citing higher cost; increased costs along with devaluation of the pound had raised the cost to around £3 million each.{{Sfn|Gardner|1981|p= 116}} The first two F-111Ks (one strike/recon F-111K and one trainer/strike TF-111K) were in the final stages of assembly when the order was canceled. All of the components that had been assembled for the production of the main F-111K fleet that shared commonality were diverted to the FB-111A program, while the two aircraft under construction were re-designated as YF-111As with the intention that they be used as test aircraft in the F-111A program. Ultimately however, the two F-111Ks were never operated as test aircraft – in July 1968, almost exactly a year after the first airframe began construction, the USAF decided not to take them over, and General Dynamics were ordered to use them for component recovery.
=FB-111A / F-111G{{anchor|FB-111}}=
The FB-111A was a strategic bomber version of the F-111. The USAF's Strategic Air Command needed an interim bomber due to the Advanced Manned Strategic Aircraft program proceeding slowly and the B-52 fleet's fatigue. The FB-111A was selected in 1965 and ordered in 1966 to replace the supersonic Convair B-58 Hustler and early B-52s.Logan 1998, p. 215.Knaack 1978, pp. 242-243. In 1968, plans called for 263 FB-111s, but the total was reduced to 76 aircraft in 1969. The first production aircraft flew in 1968.Miller 1982, pp. 38–41. After the UK canceled its order for the F-111K in 1968, components for the 48 F-111Ks in production were reused on the FB-111A.Gunston 1978, p. 87.Logan 1998, pp. 278–279. Deliveries began in 1969 and ended in 1971.
The FB-111A had a redesigned aft fuselage, longer F-111B wings for greater range and load-carrying ability, and a maximum speed of Mach 2.Miller 1982, pp. 38–43.Logan 1998, p. 216–218. Fuel capacity was increased by 585 gallons (2,214 L) and strengthened landing gear permitted a higher maximum takeoff weight of 119,250 lb (54,105 kg). All but the first FB-111A had the Triple Plow II intakes and the TF30-P-7 with 12,500 lbf (56 kN) dry and 20,350 lbf (90 kN) afterburning thrust.Baugher, Joe. [http://www.joebaugher.com/usaf_fighters/f111_9.html "General Dynamics FB-111A."] joebaugher.com, 22 December 1999. Retrieved: 5 October 2009.Knaack 1978, p. 244.
The FB-111A was fitted with the SAC Mark IIB avionics suite.Knaack 1978, pp. 243-245. It had an attack radar improved from the F-111A's radar, along with kit later used on the F-111D, such as the inertial navigation system, digital computers, and multi-function displays.Logan 1998, pp. 215–218. The suite also had custom items to support the strategic mission, such as a star tracker navigation system mounted forward of the cockpit, a satellite communications receiver, and an automatic stores release system that replaced the manual arrangement on other F-111 models. Armament for the strategic bombing role was the Boeing AGM-69 SRAM (short-range attack missile); two could be carried in the internal weapons bay and four more on the inner underwing pylons; nuclear gravity bombs were also usable. Fuel tanks were often carried on the third non-swivelling pylon of each wing. The FB-111A had a total weapon load of {{convert|35500|lb|kg|abbr=on|sigfig=3}}.

Multiple advanced FB-111 strategic bomber proposals were made in the 1970s. The first, referred to as "FB-111G" by General Dynamics, was a larger aircraft with more powerful engines, greater payload and range. The next was a lengthened "FB-111H" fitted with more powerful General Electric F101 turbofan engines, a {{cvt|12|ft|8.5|in|m}} longer fuselage and redesigned fixed intakes. The rear landing gear were moved outward so armament could be carried on the fuselage there. The FB-111H was offered as an alternative to the B-1A in 1975.Logan 1998, pp. 247–248.Miller 1982, pp. 59–62, 73–77. The similar FB-111B/C was offered in 1979 without success.Logan 1998, pp. 249–251.
The FB-111A became surplus to SAC's needs after the B-1B Lancer entered service; they were subsequently reconfigured for tactical use and redesignated F-111G.Davies 2013, p. 40. The conversions began in 1989 and ended after 34 F-111Gs were produced. After SAC's disestablishment, the FB-111As and F-111Gs were transferred to the newly established Air Combat Command (ACC) and used primarily for training.Logan 1998, p. 206. The remaining FB-111As were retired in 1991 and the F-111Gs were retired in 1993.Logan 1998, pp. 206, 218. Australia bought 15 F-111Gs in 1993 to supplement its F-111Cs. They were retired in 2007.
=EF-111A Raven=
{{main|General Dynamics–Grumman EF-111A Raven}}
To replace the aging Douglas EB-66, the USAF contracted Grumman in 1972 to convert 42 existing F-111As into electronic warfare aircraft. The EF-111A can be distinguished from the F-111A by the equipment bulge atop their tails. In May 1998, the USAF withdrew the final EF-111As from service, placing them in storage at Aerospace Maintenance and Regeneration Center (AMARC) at Davis–Monthan Air Force Base.Baugher, Joe.
