The '''General Dynamics F-111 Aardvark''' is a retired supersonic, medium-range, [[Multirole combat aircraft|multirole]] combat aircraft. Production models of the F-111 had roles that included [[attack aircraft|attack]] (e.g. [[Air interdiction|interdiction]]), [[strategic bomber|strategic bombing]] (including nuclear weapons capabilities), [[aerial reconnaissance|reconnaissance]] and [[electronic-warfare aircraft|electronic warfare]]. ''Aardvark'' comes from a [[aardvark|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 wing]]s, [[afterburner|afterburning]] [[turbofan]] engines, and automated [[terrain-following radar]] for [[nap-of-the-earth|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 aircraft|fighter]] variant intended for the [[United States Navy]], the [[General Dynamics–Grumman F-111B|F-111B]], was canceled before production; it was intended for [[carrier-based aircraft|aircraft carrier-based]] roles, including long-range [[interceptor aircraft|interception]]. Several specialized models, such as the FB-111A strategic bomber and the [[General Dynamics–Grumman EF-111A Raven|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 [[General Dynamics F-111C|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|{{nowrap|F-15E}} Strike Eagle]] for medium-range precision strike missions, while the supersonic bomber role has been assumed by the [[Rockwell B-1 Lancer|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]] [[Lockheed U-2|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 [[SA-2|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.<ref name="lax2010">Lax 2010, p. 15.</ref>

By 1960, SAC had begun moving to [[Terrain mask|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.<ref name=Spick_B-1B>Spick 1986, pp. 4–7.</ref> 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|Republic {{nowrap|F-105}} Thunderchief]], which was designed to deliver nuclear weapons fast and far, but required long runways.<ref name=Gunston_p12-3>Gunston 1978, pp. 12–13.</ref> A simpler [[Variable-sweep wing|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.<ref name=Thomason_p5-6>Thomason 1998, pp. 5–6.</ref><ref name="Davies2013 p6-7">Davies 2013, pp. 6-7.</ref> This led USAF leaders to encourage its use.<ref name=Miller_p10-1>Miller 1982, pp. 10–11.</ref>

In June 1960, the USAF issued specification ''SOR 183'' for a long-range interdiction/strike aircraft able to penetrate [[Soviet Union|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.<ref name='knaack 223'>Knaack 1978, p. 223.</ref> 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}}.<ref name=Miller_p10-1/> 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.<ref name='knaack 223-224'>Knaack 1978, pp. 223-224.</ref>

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 missile]]s 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 [[McDonnell Douglas F-4 Phantom II|F-4 Phantom II]] to intercept both enemy bombers and missiles.<ref name=Thomason_p3-5>Thomason 1998, pp. 3–5.</ref><ref name="Davies2013 p7">Davies 2013, p. 7.</ref> Seeking a FAD fighter, the Navy started with the [[subsonic aircraft|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.<ref name=Thomason_p3-5/>{{Sfn|Gunston|1978|p= 13}} The program was formally canceled in 1961.<ref name=Thomason_p3-5/> The Navy had tried variable geometry wings with the [[XF10F Jaguar]], but abandoned it in the early 1950s.<ref name="Davies2013 p6">Davies 2013, p. 6.</ref> It was NASA's simplification which made the variable geometry wings practical.<ref name=Thomason_p5-6/><ref name='knaack 223'/> By 1960, increases in aircraft weights required improved [[high-lift device]]s, such as variable geometry wings.{{Sfn|Gunston|1978|pp= 11–12}}<ref name=Miller_p11>Miller 1982, p. 11.</ref> Variable geometry offered high speeds, and maneuverability with heavier [[payload]]s, 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 [[United States Secretary of Defense|secretary of defense]] in January 1961.<ref name=Miller_p13>Miller 1982, p. 13.</ref> 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}}<ref name="Davies2013 p4">Davies 2013, p. 4.</ref> 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 [[TFX Program|Tactical Fighter Experimental]] (TFX), despite USAF and Navy efforts to keep their programs separate.{{Sfn|Eden|2004|pp=196–7}}<ref name=erg66colls>{{cite news |url= https://news.google.com/newspapers?id=o-VVAAAAIBAJ&sjid=EuEDAAAAIBAJ&pg=6856%2C3575947<!--https://news.google.com/newspapers?id=b5ghAAAAIBAJ&sjid=MpoFAAAAIBAJ&pg=3595%2C773184-->|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}}</ref> According to aviation author Peter E.

[[File:General Dynamics F-111A cockpit 061003-F-1234S-015.jpg|thumb|The side-by-side seating adopted in the F-111]]
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 [[Naval Flight Officer|radar operator]] to share the radar display.{{Sfn|Gunston|1978|pp=8–17}}<ref name='knaack 224'>Knaack 1978, p. 224.</ref> Also, the USAF wanted the aircraft designed for 7.33&nbsp;g with Mach&nbsp;2.5 speed at altitude and Mach&nbsp;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&nbsp;g with Mach&nbsp;2 speed at altitude and high subsonic speed (about Mach&nbsp;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}}<ref name=Miller_p11-5>Miller 1982, pp. 11–15.</ref>

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}}<ref name=Miller_p11-5/> Nevertheless, a request for proposals (RFP) for the TFX was provided to industry in October 1961.<ref name='knaack 224-225'>Knaack 1978, pp. 224-225.</ref> In December, proposals were received from [[Boeing]], [[General Dynamics]], [[Lockheed Corporation|Lockheed]], [[McDonnell Aircraft|McDonnell]], [[North American Aviation|North American]] and [[Republic Aviation|Republic]]. The evaluation group found all the proposals lacking, but Boeing and General Dynamics were selected to submit enhanced designs.<ref name='knaack 225'>Knaack 1978, p. 225.</ref> Boeing's [[Boeing 818|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 seat]]s 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.<ref name='knaack 225' /> Two more rounds of updates to the proposals were conducted, and the board eventually recommended the Boeing design.<ref name=erg66colls/>{{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.<ref name='knaack 225' /> The Boeing aircraft shared less than half of the major structural components. On 21 December 1962, General Dynamics signed the TFX contract.<ref name='knaack 225-226'>Knaack 1978, pp. 225-226.</ref> A congressional investigation into the procurement processed was conducted, but did not change the selection.<ref name=erg66colls />{{Sfn|Gunston|1978|pp=18–20}}<ref name=retplg>{{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}}</ref> 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_contract#Contract_types|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.<ref name='knaack 226'>Knaack 1978, p. 226.</ref>

===Design phase===
General Dynamics' design team was led by [[Robert H. Widmer]].<ref>{{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}}</ref> 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.<ref name=Miller_p17_9/><ref name='knaack 236'>Knaack 1978, p. 236.</ref> The General Dynamics and Grumman team faced ambitious requirements for range, weapons load, and aircraft weight.<ref>Thomason 1998, pp. 9–10.</ref> 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.<ref name=Miller_p17_9>Miller 1982, pp. 17, 19.</ref> This use of unfamiliar features has been attributed as a major cause of the aircraft's protracted development and weight increases.<ref name="Davies2013 p5">Davies 2013, p. 5.</ref>

The F-111A and F-111B shared the same airframe structural components and [[Pratt & Whitney TF30|Pratt & Whitney TF30-P-1]] turbofan engines. They featured side-by-side crew seating in an escape capsule as required by the Navy. The [[General Dynamics/Grumman F-111B|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.<ref name=Baug_F-111A>Baugher, Joe.

During September 1963, the F-111A mockup was inspected.<ref name='knaack 226' /> On 15 October 1964, the first test F-111A was rolled out of [[Air Force Plant 4|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.<ref name=Baug_F-111A/><ref name='knaack 226' /> 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.<ref name='knaack 226-227'>Knaack 1978, pp. 226-227.</ref><ref name=ctfiss>{{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}}</ref> Early flights of the F-111, which included supersonic flights, demonstrated favorably simplistic maintenance requirements, amongst other qualities.<ref name='knaack 227'>Knaack 1978, p. 227.</ref>

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.<ref name='knaack 227' /> 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.<ref name='knaack 227, 233'>Knaack 1978, pp. 227, 233.</ref> 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]].<ref name='knaack 228'>Knaack 1978, p. 228.</ref>

Early flights of the F-111 were troubled by compressor surges and stalls across certain portions of the flight regime.<ref name='knaack 227-228'>Knaack 1978, pp. 227-228.</ref> General Dynamics had elected to use an uncommon spike-shaped variable intake for the engine for the performance.<ref name="Davies2013 p5"/> 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.<ref name=Gunston_p25-7>Gunston 1978, pp. 25–27.</ref><ref name=FASweb>{{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}}</ref><ref name='knaack 228-229'>Knaack 1978, pp. 228-229.</ref> During February 1965, the F-111A achieved a speed of Mach 1.3 while flying with an interim intake design.<ref name=Gunston_p25-7/> On 18 May 1965, the <!--first-->F-111B made its first flight; it was also equipped with ejector seats initially.<ref name=Baugher_F-111B>Baugher, Joe.

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.<ref name=Gunston_1983_p30>Gunston 1983, p. 30.</ref>

The F-111C and F-111F were equipped to carry the [[Pave Tack|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]]/[[Laser designator|designator]]. The Pave Tack pod allowed the F-111 to designate targets and drop [[laser-guided bomb]]s on them.<ref>Logan 1998, pp. 29–30.</ref> Australian RF-111Cs carried a pallet of sensors and [[camera]]s for aerial reconnaissance use.<ref name=Miller_p31>Miller 1982, p. 31.</ref>

==== External ordnance ====
[[File:F-111 with Durandal.jpg|thumb|F-111 external payload of [[Matra Durandal]] 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.<ref name=Gunston_1983_p30-1>Gunston 1983, pp. 30–31.</ref>

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 countermeasure]]s (ECM) pods or [[datalink]] pods; one station was on the weapons bay, and the other on the rear fuselage between the engines.<ref name=Gunston_1983_p23-4/> The F-111's maximum practical weapons load was limited, since the fixed pylons could not be used with the wings fully swept.<ref name=Logan_p18>Logan 1998, p. 18.</ref>

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.<ref name=Gunston_1983_p30/> Australian F-111Cs were equipped to launch the [[Harpoon (missile)|Harpoon]] anti-ship missile, and the [[Popeye (missile)|Popeye]] stand-off missile.<ref name=Logan_p28>Logan 1998, p. 28.</ref> 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.<ref name=Gunston_1983_p49>Gunston 1983, p. 49.</ref>

===Historical significance===
The F-111 was the first production variable-geometry wing aircraft.<ref name=Logan_p14 /> Several other types have followed with similar swing-wing configuration,<ref name=Logan_p14/> 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.<ref name=Gunston_1983_p3>Gunston 1983, p. 3.</ref> 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|thumb|right|''Combat Lancer'' F-111As over Southeast Asia in 1968|alt=Two green jet aircraft flying together, right of wing. Further out in the background is another jet aircraft.]]

The first of six initial production F-111s was delivered on 17 July 1967 to fighter squadrons at [[Nellis Air Force Base]].<ref>Gunston 1983, p. 32.</ref><ref name=Logan_p33>Logan 1998, p. 33.</ref> These aircraft were used for crew training. [[428th Fighter Squadron|428th Tactical Fighter Squadron]] achieved [[initial operational capability]] on 28 April 1968.<ref name=Logan_p33/><ref name='knaack 229'>Knaack 1978, p. 229.</ref>

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]].<ref name='knaack 229-230'>Knaack 1978, pp. 229-230.</ref> 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.<ref>Davies and Thornborough 1997, pp. 40, 43.</ref> 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.<ref>Thornborough and Davies 1989, p. 34.</ref>

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.<ref>Thornborough and Davies 1989, p. 33.</ref>

During September 1972, the F-111 returned to Southeast Asia, stationed at [[Takhli Royal Thai Air Force Base|Takhli Air Base]], Thailand.<ref name='knaack 231-232'>Knaack 1978, pp. 231-232.</ref> 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,<ref name=Logan_p283/> who called the aircraft "Whispering Death".<ref name="thedrive20160727">{{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}}</ref> They also supported regional aerial operations against other communist forces such as [[Operation Phou Phiang III]] during the [[Laotian Civil War]] in [[Laos]].<ref>Thornborough and Davies 1989, p. 37.</ref> Crews described their flying in Vietnam as "speed is life", "one pass, haul ass", and "you do more than one pass in a target area you die".

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.<ref name=Logan_p283>Logan 1998, pp. 283–284.</ref><ref name='knaack 232'>Knaack 1978, p. 232.</ref>

From 30 July 1973, F-111As of the [[347th Rescue Wing|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]].<ref>{{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}}</ref> The 347th TFW was stationed at [[Korat Royal Thai Air Force Base]] from 12 July 1974 until 30 June 1975.

One of the most unusual missions occurred on 14 February 1986, when two FB-111s of the [[509th Bombardment Wing]] were dispatched from then [[Pease Air Force Base]], New Hampshire to [[Tinker Air Force Base]], Oklahoma to pick up a heart for transplant.

On 14 April 1986, 18 F-111s and approximately 25 Navy aircraft conducted air strikes against [[Libya]] under [[1986 United States bombing of Libya|Operation El Dorado Canyon]]. The 18 F-111s of the [[48th Fighter Wing|48th Tactical Fighter Wing]] and 4 EF-111As from the [[20th Fighter Wing|20th Tactical Fighter Wing]] flew what turned out to be the longest fighter combat mission in history.<ref name=AF_mag_El_Dorado/> The round-trip flight between [[RAF Lakenheath]]/[[RAF Upper Heyford]], United Kingdom and Libya of {{convert|6400|mi|km}} spanned 13 hours.

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&nbsp;lbf (53&nbsp;kN) dry and 18,500&nbsp;lbf (82&nbsp;kN) afterburning thrust<ref name=Baug_F-111A/> and "Triple Plow I" variable intakes, providing a maximum speed of Mach 2.3 (1,450&nbsp;mph, 2,300&nbsp;km/h) at altitude.<ref name=Miller_p26_66>Miller 1982, pp. 26, 66.</ref> 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}}.<ref name=Logan_p302>Logan 1998, p. 302.</ref>

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 Industries|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}}).<ref name=Gunston_p46-7>Gunston 1978, pp. 46–47.</ref>

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.<ref>Thomason 1998, p. 54.</ref>

===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]].<ref name="Davies2013 p38-39">Davies 2013, pp. 38-39.</ref><ref name='knaack 249-250'>Knaack 1978, pp. 249-250.</ref> It was first ordered in 1967 and delivered from 1970–73 after delays due to avionics issues.<ref name='knaack 252-253'>Knaack 1978, pp. 252-253.</ref> 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.<ref name=Logan_p106-7>Logan 1998, pp. 26, 106–107.</ref>

The F-111D used the new Triple Plow II intakes, which were located four inches (100&nbsp;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&nbsp;lbf (53&nbsp;kN) dry and 18,500&nbsp;lbf (82&nbsp;kN) afterburning thrust.<ref name='knaack 250-252'>Knaack 1978, pp. 250–252.</ref>

The Mark II avionics used digitally integrated microprocessors, some of the first used by the USAF, offering new capability but substantial problems.<ref name='knaack 253-255'>Knaack 1978, p. 253-255.</ref> The [[Rockwell International|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 display]]s (MFDs). The terrain-following radar was the [[Sperry Corporation|Sperry]] AN/APQ-128.<ref name=Logan_p26-7>Logan 1998, pp. 26–27.</ref> The attack radar featured a Doppler beam-sharpening, [[moving target indication]] (MTI), and [[Continuous-wave radar]] for guiding [[semi-active radar homing]] missiles.<ref name=Miller_p31 /><ref name=Gunston_p94-5>Gunston 1978, pp. 94–95.</ref> Avionics reliability improved but some issues were never fully resolved;<ref name=Miller_p31/><ref name=Logan_p106-7/> according to Crandall, "The truth is that the D model didn't work.

===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.<ref name=Gunston_p74-6>Gunston 1978, pp. 74–76.</ref><ref name="Davies2013 p39">Davies 2013, p. 39.</ref> The weapon stores management system was improved and other small changes made.<ref name=Miller_p32>Miller 1982, p. 32.</ref> 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.<ref name=Logan_p137-8>Logan 1998, pp. 137–138.</ref><ref name='knaack 238'>Knaack 1978, p. 238.</ref> 94 F-111Es were delivered between 1969 and 1971.<ref name=Miller_p32/> Many F-111Es were assigned to the 20th TFW at Upper Heyford, UK until 1991.<ref name='knaack 239'>Knaack 1978, p. 239.</ref> 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.<ref name=Logan_p138>Logan 1998, p. 138.</ref>

===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.<ref name=Gunston_p95-7>Gunston 1978, pp. 95–97.</ref><ref name='knaack 256'>Knaack 1978, p. 256.</ref> 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.<ref name=Logan_p169-71>Logan 1998, pp. 169–171.</ref><ref name="Davies2013 p39-40">Davies 2013, pp. 39-40.</ref>

The F-111F could reach Mach 1.2 at sea level on full afterburner.<ref>{{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}}</ref> It had the Triple Plow II intakes along with the substantially more powerful TF30-P-100 turbofan with 25,100&nbsp;lbf (112&nbsp;kN) afterburning thrust, 35% more thrust than the F-111A and E.<ref name=FASweb /> An adjustable engine nozzle was added to decrease drag.<ref name=Logan_p169-71/> The P-100 engine greatly improved performance.<ref name=Gunston_p96>Gunston 1978, p. 96.</ref><ref name='knaack 257'>Knaack 1978, p. 257.</ref> The engines were upgraded to the TF30-P-109 version between 1985 and 1986.<ref name=Logan_p301>Logan 1998, p. 301.</ref>

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&nbsp;mi (4.0&nbsp;km) display ring. Although tested with digital moving-target indicator (MTI) capacity, it was not used in production sets.<ref name=Gunston_p95-7/> 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.<ref name=Logan_p27-169>Logan 1998, pp. 27, 169.</ref> 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.<ref>[http://www.flightglobal.com/pdfarchive/view/1982/1982%20-%200080.html "Pave Tack operational on European F-111s."] ''Flight International'', 9 January 1982.</ref>{{r|thedrive20160727}} The Pacer Strike avionics update program replaced analog equipment with new digital equipment and multi-function displays.<ref name=Logan_p28-9>Logan 1998, pp. 28–29.</ref> The last USAF F-111s were withdrawn from service in 1996, replaced by the [[McDonnell Douglas F-15E Strike Eagle]].<ref>[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.</ref>

===F-111K===
{{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.<ref name=Gunston_p84-7>Gunston 1978, pp. 84–87.</ref> The F-111K was to be supplemented later by the [[AFVG|Anglo-French Variable Geometry Aircraft]] then under development. The F-111K was based on the F-111A with longer F-111B wings,<ref name=Gunston_p84-7/> 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.<ref name=Logan_p278-80>Logan 1998, pp. 278–80.</ref><ref name="Davies2013 p40-41">Davies 2013, pp. 40-41.</ref>

In January 1968, the United Kingdom terminated its F-111K order,<ref name=Logan_p278-80/> citing higher cost; increased costs along with [[devaluation]] of the [[Pound sterling|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.<ref name=Logan_p278-80 /> 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.<ref name=Gunston_p84-7 />

[[File:FB-111 Formation.jpg|thumb|An overhead view of two FB-111s in formation|alt=An air-to-air front overhead view of two FB-111s in formation]]

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 [[Boeing B-52 Stratofortress|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.<ref name=Logan_p215>Logan 1998, p. 215.</ref><ref name='knaack 242-243'>Knaack 1978, pp. 242-243.</ref> 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.<ref name=Miller_p38-41>Miller 1982, pp. 38–41.</ref> 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.<ref name=Gunston_p87>Gunston 1978, p. 87.</ref><ref name=Logan_p278-79>Logan 1998, pp. 278–279.</ref> Deliveries began in 1969 and ended in 1971.<ref name=Logan_p216-8/>

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.<ref name=Miller_p38-43>Miller 1982, pp. 38–43.</ref><ref name=Logan_p216-8>Logan 1998, p. 216–218.</ref> Fuel capacity was increased by 585 gallons (2,214 L) and strengthened [[landing gear]] permitted a higher maximum takeoff weight of 119,250&nbsp;lb (54,105&nbsp;kg). All but the first FB-111A had the Triple Plow II intakes and the TF30-P-7 with 12,500&nbsp;lbf (56&nbsp;kN) dry and 20,350&nbsp;lbf (90&nbsp;kN) afterburning thrust.<ref name=Baugher_FB-111A>Baugher, Joe.

The FB-111A was fitted with the SAC Mark IIB avionics suite.<ref name='knaack 243-245'>Knaack 1978, pp. 243-245.</ref> 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 computer]]s, and multi-function displays.<ref name=Logan_p215-18>Logan 1998, pp. 215–218.</ref> 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.<ref name="AirVectors"/> 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}}.<ref name=Baugher_FB-111A/>

[[File:Artist Concept of F-111 1980.JPEG|right|thumb|Artist concept of a lengthened FB-111]]
Multiple advanced FB-111 strategic bomber proposals were made in the 1970s. The first, referred to as "FB-111G" by General Dynamics,<ref name=Logan_p247-8/> 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.<ref name=Logan_p247-8>Logan 1998, pp. 247–248.</ref><ref name=Miller_p59-77>Miller 1982, pp. 59–62, 73–77.</ref> The similar FB-111B/C was offered in 1979 without success.<ref name=Logan_p249-51>Logan 1998, pp. 249–251.</ref>

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''.<ref name="Davies2013 p40">Davies 2013, p. 40.</ref> 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.<ref name=Logan_p206>Logan 1998, p. 206.</ref> The remaining FB-111As were retired in 1991 and the F-111Gs were retired in 1993.<ref name=Logan_p206_218>Logan 1998, pp. 206, 218.</ref> Australia bought 15 F-111Gs in 1993 to supplement its F-111Cs.<ref name=Logan_p206_218/> They were retired in 2007.

===EF-111A Raven===
{{main|General Dynamics–Grumman EF-111A Raven}}

To replace the aging [[B-66 Destroyer|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]].<ref name=autogenerated1>Baugher, Joe.
