The General Dynamics F-16 Fighting Falcon is an American single-engine
air superiority day fighter, it evolved into a successful all-weather multirole aircraft with over 4,600 built since 1976.[4] Although no longer purchased by the U.S. Air Force, improved versions are being built for export. In 1993, General Dynamics sold its aircraft manufacturing business to the Lockheed Corporation,[5] which became part of Lockheed Martin after a 1995 merger with Martin Marietta.[6]
The F-16's key features include a frameless bubble canopy for enhanced cockpit visibility, a side-mounted control stick to ease control while maneuvering, an ejection seat reclined 30 degrees from vertical to reduce the effect of g-forces on the pilot, and the first use of a relaxed static stability/fly-by-wire flight control system that helps to make it an agile aircraft. The fighter has a single turbofan engine, an internal M61 Vulcan cannon and 11 hardpoints. Although officially named "Fighting Falcon", the aircraft is commonly known by the nickname "Viper" among its crews and pilots.[7]
In addition to active duty in the U.S. Air Force,
U.S. Air Force Thunderbirds aerial demonstration team, the US Air Combat Command F-16 Viper Demonstration Team,[8] and as an adversary/aggressor aircraft by the United States Navy. The F-16 has also been procured by the air forces of 25 other nations.[9] As of 2025, it is the world's most common fixed-wing aircraft in military service, with 2,084 F-16s operational.[10]
US Vietnam War experience showed the need for air superiority fighters and better air-to-air training for fighter pilots.[11] Based on his experience in the Korean War and as a fighter tactics instructor in the early 1960s, Colonel John Boyd with mathematician Thomas Christie developed the energy–maneuverability theory to model a fighter aircraft's performance in combat. Boyd's work called for a small, lightweight aircraft that could maneuver with the minimum possible energy loss and which also incorporated an increased thrust-to-weight ratio.[12][13] In the late 1960s, Boyd gathered a group of like-minded innovators who became known as the Fighter Mafia, and in 1969, they secured Department of Defense funding for General Dynamics and Northrop to study design concepts based on the theory.[14][15]
Air Force F-X proponents were opposed to the concept because they perceived it as a threat to the F-15 program, but the USAF's leadership understood that its budget would not allow it to purchase enough F-15 aircraft to satisfy all of its missions.[16] The Advanced Day Fighter concept, renamed F-XX, gained civilian political support under the reform-minded Deputy Secretary of Defense David Packard, who favored the idea of competitive prototyping. As a result, in May 1971, the Air Force Prototype Study Group was established, with Boyd a key member, and two of its six proposals would be funded, one being the Lightweight Fighter (LWF). The request for proposals issued on 6 January 1972 called for a 20,000-pound (9,100 kg) class air-to-air day fighter with a good turn rate, acceleration, and range, and optimized for combat at speeds of Mach 0.6–1.6 and altitudes of 30,000–40,000 feet (9,100–12,000 m). This was the region where USAF studies predicted most future air combat would occur. The anticipated average flyaway cost of a production version was $3 million. This production plan was hypothetical as the USAF had no firm plans to procure the winner.[17][18]
Selection of finalists and flyoff

Five companies responded, and in 1972, the Air Staff selected General Dynamics' Model 401 and Northrop's P-600 for the follow-on prototype development and testing phase. GD and Northrop were awarded contracts worth $37.9 million and $39.8 million to produce the YF-16 and
which?] successfully advocated the idea of complementary fighters in a high-cost/low-cost force mix.[19] The "high/low mix" would allow the USAF to be able to afford sufficient fighters for its overall fighter force structure requirements. The mix gained broad acceptance by the time of the prototypes' flyoff, defining the relationship between the LWF and the F-15.[20][21]
The YF-16 was developed by a team of General Dynamics engineers led by
sorties for a total of 417 flight hours;[24] the YF-17s flew 288 sorties, covering 345 hours.[25]
Air Combat Fighter competition
Increased interest turned the LWF into a serious acquisition program. NATO allies Belgium, Denmark, the Netherlands, and Norway were seeking to replace their F-104G Starfighterfighter-bombers.[26] In early 1974, they reached an agreement with the U.S. that if the USAF ordered the LWF winner, they would consider ordering it as well. The USAF also needed to replace its F-105 Thunderchief and F-4 Phantom II fighter-bombers. The U.S. Congress sought greater commonality in fighter procurements by the Air Force and Navy, and in August 1974 redirected Navy funds to a new Navy Air Combat Fighter program that would be a naval fighter-bomber variant of the LWF. The four NATO allies had formed the Multinational Fighter Program Group (MFPG) and pressed for a U.S. decision by December 1974; thus, the USAF accelerated testing.[27][28][29]
Virginia Air and Space Center
To reflect this serious intent to procure a new fighter-bomber, the LWF program was rolled into a new Air Combat Fighter (ACF) competition in an announcement by U.S. Secretary of DefenseJames R. Schlesinger in April 1974. The ACF would not be a pure fighter, but multirole, and Schlesinger made it clear that any ACF order would be in addition to the F-15, which extinguished opposition to the LWF.[28][29][30] ACF also raised the stakes for GD and Northrop because it brought in competitors intent on securing what was touted at the time as "the arms deal of the century".[31] These were Dassault-Breguet's proposed Mirage F1M-53, the Anglo-French SEPECAT Jaguar, and the proposed Saab 37E "Eurofighter". Northrop offered the P-530 Cobra, which was similar to the YF-17. The Jaguar and Cobra were dropped by the MFPG early on, leaving two European and two U.S. candidates. On 11 September 1974, the U.S. Air Force confirmed plans to order the winning ACF design to equip five tactical fighter wings. Though computer modeling predicted a close contest, the YF-16 proved significantly quicker going from one maneuver to the next and was the unanimous choice of those pilots that flew both aircraft.[32]
On 13 January 1975,
Secretary of the Air Force John L. McLucas announced the YF-16 as the winner of the ACF competition.[33] The chief reasons given by the secretary were the YF-16's lower operating costs, greater range, and maneuver performance that was "significantly better" than that of the YF-17, especially at supersonic speeds. Another advantage of the YF-16 – unlike the YF-17 – was its use of the Pratt & Whitney F100 turbofan engine, the same powerplant used by the F-15; such commonality would lower the cost of engines for both programs.[34] Secretary McLucas announced that the USAF planned to order at least 650, possibly up to 1,400 production F-16s. In the Navy Air Combat Fighter competition, on 2 May 1975, the Navy selected the YF-17 as the basis for what would become the McDonnell Douglas F/A-18 Hornet.[35][36]
Production
Air Combat Maneuvering Instrumentation
pod, and a centerline fuel tank (300 US gal or 1,100 L capacity)
The U.S. Air Force initially ordered 15 full-scale development (FSD) aircraft (11 single-seat and four two-seat models) for its flight test program which was reduced to eight (six F-16A single-seaters and two F-16B two-seaters).[37] The YF-16 design was altered for the production F-16. The fuselage was lengthened by 10.6 in (0.269 m), a larger nose radome was fitted for the AN/APG-66 radar, wing area was increased from 280 to 300 sq ft (26 to 28 m2), the tailfin height was decreased, the ventral fins were enlarged, two more stores stations were added, and a single door replaced the original nosewheel double doors. The F-16's weight was increased by 25% over the YF-16 by these modifications.[38][39]
The FSD F-16s were manufactured by General Dynamics in
The F-16 was given its name of "Fighting Falcon" on 21 July 1980. Its pilots and crews often use the name "Viper" instead, because of a perceived resemblance to a
starfighter from the television program Battlestar Galactica, which aired at the time the F-16 entered service.[41][7]
On 7 June 1975, the four European partners, now known as the
Medium Multi-Role Combat Aircraft procurement, a sixth F-16 production line would have been built in India.[44] In May 2013, Lockheed Martin stated there were currently enough orders to keep producing the F-16 until 2017.[45]
Improvements and upgrades
One change made during production was augmented pitch control to avoid
deep stall conditions at high angles of attack. The stall issue had been raised during development but had originally been discounted. Model tests of the YF-16 conducted by the Langley Research Center revealed a potential problem, but no other laboratory was able to duplicate it. YF-16 flight tests were not sufficient to expose the issue; later flight testing on the FSD aircraft demonstrated a real concern. In response, the area of each horizontal stabilizer was increased by 25% on the Block 15 aircraft in 1981 and later retrofitted to earlier aircraft. In addition, a manual override switch to disable the horizontal stabilizer flight limiter was prominently placed on the control console, allowing the pilot to regain control of the horizontal stabilizers (which the flight limiters otherwise lock in place) and recover. Besides reducing the risk of deep stalls, the larger horizontal tail also improved stability and permitted faster takeoff rotation.[46][47]
In the 1980s, the Multinational Staged Improvement Program (MSIP) was conducted to evolve the F-16's capabilities, mitigate risks during technology development, and ensure the aircraft's worth. The program upgraded the F-16 in three stages. The MSIP process permitted the quick introduction of new capabilities, at lower costs and with reduced risks compared to traditional independent upgrade programs.[48] In 2012, the USAF had allocated $2.8 billion (~$3.67 billion in 2023) to upgrade 350 F-16s while waiting for the F-35 to enter service.[49] One key upgrade has been an auto-GCAS (Ground collision avoidance system) to reduce instances of controlled flight into terrain.[50] Onboard power and cooling capacities limit the scope of upgrades, which often involve the addition of more power-hungry avionics.[51]
Lockheed won many contracts to upgrade foreign operators' F-16s. BAE Systems also offers various F-16 upgrades, receiving orders from South Korea, Oman, Turkey, and the US Air National Guard;[52][53][54] BAE lost the South Korean contract because of a price breach in November 2014.[55] In 2012, the USAF assigned the total upgrade contract to Lockheed Martin.[56] Upgrades include Raytheon's Center Display Unit, which replaces several analog flight instruments with a single digital display.[57]
In 2013,
sequestration budget cuts cast doubt on the USAF's ability to complete the Combat Avionics Programmed Extension Suite (CAPES), a part of secondary programs such as Taiwan's F-16 upgrade.[58]Air Combat Command's General Mike Hostage stated that if he only had money for a service life extension program (SLEP) or CAPES, he would fund SLEP to keep the aircraft flying.[59] Lockheed Martin responded to talk of CAPES cancellation with a fixed-price upgrade package for foreign users.[60] CAPES was not included in the Pentagon's 2015 budget request.[61] The USAF said that the upgrade package will still be offered to Taiwan's Republic of China Air Force, and Lockheed said that some common elements with the F-35 will keep the radar's unit costs down.[62] In 2014, the USAF issued a RFI to SLEP 300 F-16 C/Ds.[63]
Production relocation
To make more room for assembly of its newer F-35 Lightning II fighter aircraft, Lockheed Martin moved the F-16 production from Fort Worth, Texas to its plant in Greenville, South Carolina.[3] Lockheed delivered the last F-16 from Fort Worth to the Iraqi Air Force on 14 November 2017, ending 40 years of F-16 production there. The company resumed production in 2019, though engineering and modernization work will remain in Fort Worth.[64] A gap in orders made it possible to stop production during the move; after completing orders for the last Iraqi purchase,[65] the company was negotiating an F-16 sale to Bahrain that would be produced in Greenville. This contract was signed in June 2018,[2] and the first planes rolled off the Greenville line in 2023.[66]
Design
Overview
Early

Comparison between F-16's inset cannon; early aircraft had four leading vents, a grille, and four trailing vents, while later aircraft had only two trailing vents
The F-16 is a single-engine, highly maneuverable, supersonic, multirole tactical fighter aircraft. It is much smaller and lighter than its predecessors but uses advanced aerodynamics and avionics, including the first use of a relaxed static stability/fly-by-wire (RSS/FBW) flight control system, to achieve enhanced maneuver performance. Highly agile, the F-16 was the first fighter aircraft purpose-built to pull 9-g maneuvers and can reach a maximum speed of over Mach 2. Innovations include a frameless bubble canopy for better visibility, a side-mounted control stick, and a reclined seat to reduce g-force effects on the pilot. It is armed with an internal 20 mm M61 Vulcan cannon in the left wing root and has multiple locations for mounting various missiles, bombs and pods. It has a thrust-to-weight ratio greater than one, providing power to climb and vertical acceleration.[67]
The F-16 was designed to be relatively inexpensive to build and simpler to maintain than earlier-generation fighters. The airframe is built with about 80% aviation-grade
Although the LWF program called for a structural life of 4,000 flight hours, capable of achieving 7.33 g with 80% internal fuel; GD's engineers decided to design the F-16's airframe life for 8,000 hours and for 9-g maneuvers on full internal fuel. This proved advantageous when the aircraft's mission changed from solely air-to-air combat to multirole operations. Changes in operational use and additional systems have increased weight, necessitating multiple structural strengthening programs.[69]

Armament

Early F-16s could be armed with up to six
wing flutter.[75] The aircraft can carry various other AAMs, a wide variety of air-to-ground missiles, rockets or bombs; electronic countermeasures (ECM), navigation, targeting or weapons pods; and fuel tanks on 9 hardpoints – six under the wings, two on wingtips, and one under the fuselage. Two other locations under the fuselage are available for sensor or radar pods.[74] The F-16 carries a 20 mm (0.79 in)M61A1 Vulcan cannon, which is mounted inside the fuselage to the left of the cockpit.[74]
Relaxed stability and fly-by-wire

The F-16 is the first production fighter aircraft intentionally designed to be slightly aerodynamically unstable, also known as relaxed static stability (RSS), to both reduce drag and improve maneuverability.
attitude if the pilot releases the controls. This reduces maneuverability as the inherent stability has to be overcome and increases a form of drag known as trim drag. Aircraft with relaxed stability are designed to be able to augment their stability characteristics while maneuvering to increase lift and reduce drag, thus greatly increasing their maneuverability. At Mach 1, the F-16 gains positive stability because of aerodynamic changes.[77][78][79]
To counter the tendency to depart from controlled flight and avoid the need for constant trim inputs by the pilot, the F-16 has a quadruplex (four-channel)
skids, or a high AOA inducing a stall. The limiters also prevent maneuvers that would exert more than a 9-g load.[80][81]
Flight testing revealed that "assaulting" multiple limiters at high AOA and low speed can result in an AOA far exceeding the 25° limit, colloquially referred to as "departing"; this causes a deep stall; a near-freefall at 50° to 60° AOA, either upright or inverted. While at a very high AOA, the aircraft's attitude is stable but control surfaces are ineffective. The pitch limiter locks the stabilators at an extreme pitch-up or pitch-down attempting to recover. This can be overridden so the pilot can "rock" the nose via pitch control to recover.[82]
Unlike the YF-17, which had
flight control surfaces.[83] The F-16 is entirely reliant on its electrical systems to relay flight commands, instead of traditional mechanically linked controls, leading to the early moniker of "the electric jet" and aphorisms among pilots such as "You don't fly an F-16; it flies you."[84] The quadruplex design permits "graceful degradation" in flight control response in that the loss of one channel renders the FLCS a "triplex" system.[85][86] The FLCC began as an analog system on the A/B variants but has been supplanted by a digital computer system beginning with the F-16C/D Block 40.[87][88] The F-16's controls suffered from a sensitivity to static electricity or electrostatic discharge (ESD) and lightning.[89] Up to 70–80% of the C/D models' electronics were vulnerable to ESD.[90]
Cockpit and ergonomics
Bubble canopy, allowing all-round visibility
A key feature of the F-16's cockpit is the exceptional field of view. The single-piece,
zero/zero ejection seat is reclined at an unusual tilt-back angle of 30°; most fighters have a tilted seat at 13–15°. The tilted seat can accommodate taller pilots and increases g-force tolerance; however, it has been associated with reports of neck aches, possibly caused by incorrect headrest usage.[92] Subsequent U.S. fighters have adopted more modest tilt-back angles of 20°.[44][93] Because of the seat angle and the canopy's thickness, the ejection seat lacks canopy-breakers for emergency egress; instead the entire canopy is jettisoned prior to the seat's rocket firing.[94]
The pilot flies primarily by means of an armrest-mounted side-stick controller (instead of a traditional center-mounted stick) and an engine throttle; conventional rudder pedals are also employed. To enhance the pilot's degree of control of the aircraft during high-g combat maneuvers, various switches and function controls were moved to centralized hands on throttle-and-stick (HOTAS) controls upon both the controllers and the throttle. Hand pressure on the side-stick controller is transmitted by electrical signals via the FBW system to adjust various flight control surfaces to maneuver the F-16. Originally, the side-stick controller was non-moving, but this proved uncomfortable and difficult for pilots to adjust to, sometimes resulting in a tendency to "over-rotate" during takeoffs, so the control stick was given a small amount of "play". Since the introduction of the F-16, HOTAS controls have become a standard feature on modern fighters.[citation needed]
Joint Helmet Mounted Cueing System and cockpit head-up display
planar array antenna was designed to be compact to fit into the F-16's relatively small nose. In uplook mode, the APG-66 uses a low pulse-repetition frequency (PRF) for medium- and high-altitude target detection in a low-clutter environment, and in look-down/shoot-down employs a medium PRF for heavy clutter environments. It has four operating frequencies within the X band, and provides four air-to-air and seven air-to-ground operating modes for combat, even at night or in bad weather. The Block 15's APG-66(V)2 model added more powerful signal processing, higher output power, improved reliability, and increased range in cluttered or jamming environments. The Mid-Life Update (MLU) program introduced a new model, APG-66(V)2A, which features higher speed and more memory.[99]

synthetic aperture radar (SAR) mode for high-resolution mapping and target detection-recognition. In August 2004, Northrop Grumman was contracted to upgrade the APG-68 radars of Block 40/42/50/52 aircraft to the (V)10 standard, providing all-weather autonomous detection and targeting for Global Positioning System (GPS)-aided precision weapons, SAR mapping, and terrain-following radar (TF) modes, as well as interleaving of all modes.[44]
The F-16E/F is outfitted with Northrop Grumman's AN/APG-80active electronically scanned array (AESA) radar.[100] Northrop Grumman developed the latest AESA radar upgrade for the F-16 (selected for USAF and Taiwan's Republic of China Air Force F-16 upgrades), named the AN/APG-83 Scalable Agile Beam Radar (SABR).[101][102] In July 2007, Raytheon announced that it was developing a Next Generation Radar (RANGR) based on its earlier AN/APG-79 AESA radar as a competitor to Northrop Grumman's AN/APG-68 and AN/APG-80 for the F-16.[44] On 28 February 2020, Northrop Grumman received an order from USAF to extend the service lives of their F-16s to at least 2048 with AN/APG-83 as part of the service-life extension program (SLEP).[103]
Propulsion

The initial powerplant selected for the single-engined F-16 was the Pratt & Whitney F100-PW-200
dead-stick landing" distance of its bases.[16] It was the standard F-16 engine through the Block 25, except for the newly built Block 15s with the Operational Capability Upgrade (OCU). The OCU introduced the 23,770 lbf (105.7 kN) F100-PW-220, later installed on Block 32 and 42 aircraft: the main advance being a Digital Electronic Engine Control (DEEC) unit, which improved reliability and reduced stall occurrence. Beginning production in 1988, the "-220" also supplanted the F-15's "-100", for commonality. Many of the "-220" engines on Block 25 and later aircraft were upgraded from 1997 onwards to the "-220E" standard, which enhanced reliability and maintainability; unscheduled engine removals were reduced by 35%.[104]
Adjustable exhaust nozzle in contracted position
The F100-PW-220/220E was the result of the USAF's Alternate Fighter Engine (AFE) program (colloquially known as "the Great Engine War"), which also saw the entry of General Electric as an F-16 engine provider. Its F110-GE-100 turbofan was limited by the original inlet to a thrust of 25,735 lbf (114.47 kN), the Modular Common Inlet Duct allowed the F110 to achieve its maximum thrust of 28,984 lbf (128.93 kN). (To distinguish between aircraft equipped with these two engines and inlets, from the Block 30 series on, blocks ending in "0" (e.g., Block 30) are powered by GE, and blocks ending in "2" (e.g., Block 32) are fitted with Pratt & Whitney engines.)[104][105]
The Increased Performance Engine (IPE) program led to the 29,588 lbf (131.61 kN) F110-GE-129 on the Block 50 and 29,160 lbf (129.7 kN) F100-PW-229 on the Block 52. F-16s began flying with these IPE engines in the early 1990s. Altogether, of the 1,446 F-16C/Ds ordered by the USAF, 556 were fitted with F100-series engines and 890 with F110s.[44] The United Arab Emirates' Block 60 is powered by the General Electric F110-GE-132 turbofan with a maximum thrust of 32,500 lbf (145 kN), the highest thrust engine developed for the F-16.[106]
On 11 September 2001, two unarmed F-16s were launched in an attempt to ram and down
Washington D.C. during the 11 September 2001 terrorist attacks, but Flight 93 was prematurely brought down by the hijackers after passengers attacked the cockpit, so the F-16s were retasked to patrol the local airspace and later escorted Air Force One back to Washington.[108][109][importance?

The F-16 had been scheduled to remain in service with the U.S. Air Force until 2025.[110] Its replacement is planned to be the F-35A variant of the Lockheed Martin F-35 Lightning II, which is expected to gradually begin replacing several multirole aircraft among the program's member nations. However, owing to delays in the F-35 program, all USAF F-16s will receive service life extension upgrades.[111] In 2022, it was announced the USAF would continue to operate the F-16 for another two decades.[112]

The following year, during the 1982 Lebanon War Israeli F-16s engaged Syrian aircraft in one of the largest air battles involving jet aircraft, which began on 9 June and continued for two more days. Israeli Air Force F-16s were credited with 44 air-to-air kills during the conflict.[114][116]

The F-16I was part of a bombing mission against Syrian and Iranian targets around Damascus after an Iranian drone entered Israeli airspace and was shot down.[123] An Israel Air Force investigation determined on 27 February 2018 that the loss was due to pilot error since the IAF determined the air crew did not adequately defend themselves.[124]
On 16 July 2024, the last single-seat F-16C Barak-1 (‘Lightning’ in Hebrew) were retired; the IAF continue to use the F-16D Brakeet and F-16I Sufa two-seat variants.[125]

During the
Tail Choppers and Griffin squadrons using mostly AIM-9 Sidewinder missiles, shot down four AfghanSu-22s, two MiG-23s, one Su-25, and one An-26.[127] Most of these kills were by missiles, but at least one, a Su-22, was destroyed by cannon fire. One F-16 was lost in these battles. The downed F-16 was likely hit accidentally by the other F-16.[128]
On 7 June 2002, a Pakistan Air Force F-16B Block 15 (S. No. 82-605) shot down an Indian Air Force unmanned aerial vehicle, an Israeli-made Searcher II, using an AIM-9L Sidewinder missile, during a night interception near Lahore.[129]
The Pakistan Air Force has used its F-16s in various foreign and internal military exercises, such as the "Indus Vipers" exercise in 2008 conducted jointly with Turkey.[130][failed verification]
Between May 2009 and November 2011[update], the PAF F-16 fleet flew more than 5,500 sorties[
MiG-21 and one Su-30MKI belonging to the Indian Air Force.[133][134][135][136] Indian officials only confirmed the loss of one MiG-21 but denied losing any Su-30MKI in the clash and claimed the Pakistani claims as dubious.[137][138] Additionally Indian officials also claimed to have shot down one F-16 belonging to the Pakistan Air Force.[139][140] This was denied by the Pakistani side,[141] considered dubious by neutral sources,[142][143] and later backed by a report by Foreign Policy magazine, reporting that the US had completed a physical count of Pakistan's F-16s and found none missing.[144] A report by The Washington Post noted that the Pentagon and State Department refused public comment on the matter but did not deny the earlier report.[145]
Turkey
F-16 SoloTürk aerial aerobatic aircraft
The Turkish Air Force acquired its first F-16s in 1987. F-16s were later produced in Turkey under four phases of Peace Onyx programs. In 2015, they were upgraded to Block 50/52+ with CCIP by Turkish Aerospace Industries.[146] Turkish F-16s are being fitted with indigenous AESA radars and EW suite called SPEWS-II.[147]
On 18 June 1992, a Greek Mirage F1 crashed during a dogfight with a Turkish F-16.[148][149][150] On 8 February 1995, a Turkish F-16 crashed into the Aegean Sea after being intercepted by Greek Mirage F1 fighters.[151][152]
On 8 October 1996, seven months after the escalation a Greek
downing of an RF-4E on the Syrian coast, Turkish Defence Minister İsmet Yılmaz confirmed that the Turkish F-16D was shot down by a Greek Mirage 2000 with an R.550 Magic II in 1996 near Chios island.[158] Greece denies that the F-16 was shot down.[159] Both Mirage 2000 pilots reported that the F-16 caught fire and they saw one parachute.[160][161]
On 23 May 2006, two Greek F-16s intercepted a Turkish RF-4 reconnaissance aircraft and two F-16 escorts off the coast of the Greek island of Karpathos, within the Athens FIR. A mock dogfight ensued between the two sides, resulting in a midair collision[162] between a Turkish F-16 and a Greek F-16. The Turkish pilot ejected safely, but the Greek pilot died owing to damage caused by the collision.[163][164]
Turkey used its F-16s extensively in its
Operation Sun. This was the first time Turkey had mounted a night-bombing operation on a massive scale, and also the largest operation conducted by the Turkish Air Force.[165]
On 1 March 2020, two Syrian Sukhoi Su-24s were shot down by Turkish Air Force F-16s using air-to-air missiles over Syria's Idlib Governorate.[172] All four pilots safely ejected.[173] On 3 March 2020, a Syrian Arab Army Air Force L-39 combat trainer was shot down by a Turkish F-16 over Syria's Idlib province.[174] The pilot died.[175]
As a part of Turkish F-16 modernization program new air-to-air missiles are being developed and tested for the aircraft. GÖKTUĞ program led by TUBITAK SAGE has presented two types of air-to-air missiles named as Bozdogan (Merlin) and Gokdogan (Peregrine). While Bozdogan has been categorized as a Within Visual Range Air-to-Air Missile (WVRAAM), Gokdogan is a Beyond Visual Range Air-to-Air Missile (BVRAAM). On 14 April 2021, first live test exercise of Bozdogan have successfully completed and the first batch of missiles are expected to be delivered throughout the same year to the Turkish Air Force.[176][177]

On 16 February 2015, Egyptian F-16s struck weapons caches and training camps of the Islamic State (ISIS) in Libya in retaliation for the murder of 21 Egyptian Coptic Christian construction workers by masked militants affiliated with ISIS. The airstrikes killed 64 ISIS fighters, including three leaders in Derna and Sirte on the coast.[178]

MiG-29 was shot down by a Dutch F-16AM during the Kosovo War in 1999.[181] Belgian and Danish F-16s also participated in joint operations over Kosovo during the war.[181] Dutch, Belgian, Danish, and Norwegian F-16s were deployed during the 2011 intervention in Libya and in Afghanistan.[182] In Libya, Norwegian F-16s dropped almost 550 bombs and flew 596 missions,[183] some 17% of the total strike missions[184] including the bombing of Muammar Gaddafi's headquarters.[185]
In late March 2018, Croatia announced its intention to purchase 12 used Israeli F-16C/D "Barak"/"Brakeet" jets, pending U.S. approval.[186] Acquiring these F-16s would allow Croatia to retire its aging MiG-21s.[187] In January 2019, the deal was canceled because U.S. would only allow the resale if Israel stripped the planes of all the modernized electronics, while Croatia insisted on the original deal with all the upgrades installed.[188] At the end of November 2021, Croatia signed with France instead, for 12 Rafales.[189]
On 11 July 2018, Slovakia's government approved the purchase of 14 F-16 Block 70/72 to replace its aging fleet of Soviet-made MiG-29s.[190] A contract was signed on 12 December 2018 in Bratislava.[191]
Ukraine
Ukrainian Air Force F-16s
In May 2023, an international coalition consisting of the United Kingdom, the Netherlands, Belgium and Denmark announced their intention to train
European F-16 Training Center, organized by Romania, the Netherlands, and Lockheed Martin through several subcontractors, officially opened on 13 November 2023. It is located at the Romanian Air Force's 86th Air Base,[198] and Ukrainian pilots began training there in September 2024.[199] On 17 August 2023, the U.S. approved the transfer of F-16s from the Netherlands and Denmark to Ukraine after the Ukrainian pilots have completed their training.[200] The Netherlands and Denmark have announced that together they will donate up to 61 F-16AM/BM Block 15 MLU fighters to Ukraine once pilot training has been completed.[201][202]
On 13 May 2024, Danish Prime Minister Mette Frederiksen said that "F-16 from Denmark will be in the air over Ukraine within months." Denmark is sending 19 F-16s in total.[203] By the end of July 2024, the first F-16s were delivered to Ukraine.[204]
On 4 August 2024, President Zelensky announced to the public that the F-16 was now in operational service with Ukraine. Zelensky stated at an opening ceremony that: "F-16s are in Ukraine. We did it. I am proud of our guys who are mastering these jets and have already started using them for our country,".[205]
On 26 August 2024, F-16s were reportedly used to intercept Russian cruise missiles for the first time.[206] Also on 26 August, a Ukrainian F-16 crashed and the pilot, Oleksii Mes, was killed while intercepting Russian aerial targets during the cruise missile strikes. The cause is under investigation.[207]
On 30 August 2024, the Commander of the Ukrainian Air Force, Mykola Oleshchuk, was dismissed by President Zelenskyy and replaced by Lieutenant General Anatolii Kryvonozhko,[208] which was partially attributed to "indications" that the F-16 that crashed on 26 August was shot down in "a friendly fire incident". Ukrainian parliamentarian Maryana Bezuhla and Oleshchuk had previously argued over the cause of the F-16 loss.[209][210]
On 13 December 2024, the Ukrainian Air Force claimed an F-16 shot down six Russian cruise missiles. Two were shot down with "medium-range missiles", another two with "short-range missiles" and two were claimed to be downed by the 20 mm cannon.[211]
On 12 April 2025, Ukraine stated pilot Pavlo Ivanov was killed in action flying an F-16.
Saudi Arabian-led intervention in Yemen, respectively on 11 May 2015 and on 30 December 2015.[217]
On 11 October 2023, Deputy Assistant Secretary for Regional Security Mira Resnick confirmed to Jorge Argüello, Argentinean ambassador to the US, that the State Department has approved the transfer of 38 F-16s from Denmark.[218] On 16 April 2024, it was announced by defense minister Luis Petri that the country went through with the purchase of 24+1 Danish F-16s, that are to be brought up to date before they are sent to Argentina.[219] The 25th plane, an F-16B MLU Block 10, meant for mechanics training, came disassembled in an Argentinian C-130 in late December 2024.[220] Six F-16s a year are to be delivered from Denmark to Argentina until all are delivered, with the first batch expected around November 2025.[219]
In 2019, the US State Department approved the possible sale of 8 F-16 Block 70s to Bulgaria,[221] and the deal was approved by the Bulgarian parliament, and President Rumen Radev.[222] In November 2022, the purchase of a further 8 F-16 Block 70 fighters, spares, weapons and other systems was approved for delivery in 2027.[223] The Bulgarian Air Force expects delivery of the first eight new F-16 Block 70s by 2025 and the second batch of eight F-16 Block 70s is expected in 2027.[224]
Potential operators
Philippines
On 24 June 2021, the Defense Security Cooperation Agency approved the Philippines' purchase of 12 F-16s worth an estimated US$2.43 billion. However, the Philippines has yet to complete this deal due to financial constraints with negotiations ongoing.[225][226] In April 2025, the possible sale of 20 F-16s were approved.[227]
Argentina
On 18 December 2024, Argentina selected a bid for 24 F-16AM/BM aircraft from Denmark, instead of one from JF-17s from China/Pakistan.[228]
Civilian operators
Top Aces
In January 2021, Canadian defence contractor Top Aces announced that they had taken delivery of the first civilian owned F-16s to their US HQ in Mesa, Arizona.[229] In an approval process that had taken years, they had purchased a batch of 29 F-16A/B Netz from the Israeli Air Force, including several that had taken part in Operation Opera. A year later, the first of these aircraft had finished the extensive AAMS mission system upgrades including AESA radar, HMCS, ECM, and Tactical Datalink. In late 2022 they began regular operations flying as contracted aggressors for USAF F-22 and F-35 squadrons in Luke AFB and Eglin AFB, as well as supporting exercises in other USAF and USMC bases.[230]
F-16 models are denoted by increasing block numbers to denote upgrades. The blocks cover both single- and two-seat versions. A variety of software, hardware, systems, weapons compatibility, and structural enhancements have been instituted over the years to gradually upgrade production models and
The F-16A (single seat) and F-16B (two seat) were initial production variants. These variants include the Block 1, 5, 10, 15, and 20 versions. Block 15 was the first major change to the F-16 with larger horizontal stabilizers. It is the most numerous of all F-16 variants with 983 produced.[232] Around 300 earlier USAF F-16A and B aircraft were upgraded to the Block 15 Mid-Life Update (MLU) standard, getting analogous capability to F-16C/D Block 50/52 aircraft.[233][234] From 1987 a total of 214 Block 15 aircraft were upgraded to OCU (Operational Capability Upgrade) standard, with engines, structural and electronic improvements, and from 1988 all Block 15 were directly build to OCU specifications.[232] Between 1989 and 1992 a total of 271 Block 15OCU airframes (246 F-16A and 25 F-16B) were converted at the Ogden Air Logistic Center to the ADF (Air Defense Fighter) variant, with improved IFF system, radio and radar, the ability to carry advanced Beyond Visual Range missiles and the addition of a side-mounted 150,000 candlepower spotlight for visual night identification of intruders. Originally intended for Cold-War air defense of the continental U.S. airspace, with the fall of the Berlin Wall the ADF lost a clear mission, and most were mothballed starting from 1994. Some mothballed ADFs were later exported to Jordan (12 -A and 4 -B models) and Thailand (15 -A and 1 -B), while 30 -A and 4 -B models were leased to Italy from 2003 to 2012[235][236]

F-16C/D
F-16C Block 50M of the Chilean Air ForceThe F-16C (single seat) and F-16D (two seat) variants entered production in 1984. The first C/D version was the Block 25 with improved cockpit avionics and radar which added all-weather capability with beyond-visual-range (BVR) AIM-7 and AIM-120 air-air missiles. Block 30/32, 40/42, and 50/52 were later C/D versions.[237] The F-16C/D had a unit cost of US$18.8 million (1998).[67]Operational cost per flight hour has been estimated at $7,000[238] to $22,470[239] or $24,000, depending on the calculation method.[240][unreliable source?]
infrared search and track (IRST) unit; updated glass cockpit; and a helmet-mounted cueing system.[247] As of 2011, the F-16IN is no longer in the competition.[248][unreliable source?] In 2016, Lockheed Martin offered the new F-16 Block 70/72 version to India under the Make in India program.[249][250] In 2016, the Indian government offered to purchase 200 (potentially up to 300) fighters in a deal worth $13–15bn.[251] As of 2017, Lockheed Martin has agreed to manufacture F-16 Block 70 fighters in India with the Indian defense firm Tata Advanced Systems Limited. The new production line could be used to build F-16s for India and for exports.[252]
F-16IQ
In September 2010, the Defense Security Cooperation Agency informed the United States Congress of a possible Foreign Military Sale of 18 F-16IQ aircraft along with the associated equipment and services to the newly reformed Iraqi Air Force. The total value of sale was estimated at US$4.2 billion.[253] The Iraqi Air Force purchased those 18 jets in the second half of 2011, then later exercised an option to purchase 18 more for a total of 36 F-16IQs.[254] As of 2021[update], the Iraqi had lost two in accidents.[255] By 2023, the US government reported that these jets were Iraq's most capable airborne platforms with a 66 percent mission-capable rate. Their maintenance was being supported by private contractors. At the same time, Iraq's Russian-made systems were suffering from sanctions imposed in the wake of Russia's invasion of Ukraine.[256]
F-16N
The F-16N was an adversary aircraft operated by the
At the 2012 Singapore Air Show, Lockheed Martin unveiled plans for the new F-16V variant with the V suffix for its Viper nickname. It features an AN/APG-83active electronically scanned array (AESA) radar, a new mission computer and electronic warfare suite, an automated ground collision avoidance system, and various cockpit improvements; this package is an option on current production F-16s and can be retrofitted to most in service F-16s.[261][262] First flight took place 21 October 2015.[263] Taiwanese media reported that Taiwan and the U.S. both initially invested in the development of the F-16V.[264] Upgrades to Taiwan's F-16 fleet began in January 2017.[265] The first country to confirm the purchase of 16 new F-16 Block 70/72 was Bahrain.[266][267]Greece announced the upgrade of 84 F-16C/D Block 52+ and Block 52+ Advanced (Block 52M) to the latest V (Block 70/72) variant in October 2017.[268][269] Slovakia announced on 11 July 2018 that it intends to purchase 14 F-16 Block 70/72 aircraft.[270][271] Lockheed Martin has redesignated the F-16V Block 70 as the "F-21" in its offering for India's fighter requirement.[272] Taiwan's Republic of China Air Force announced on 19 March 2019 that it formally requested the purchase of an additional 66 F-16V fighters.[273] The Trump administration approved the sale on 20 August 2019.[274][275] On 14 August 2020, Lockheed Martin was awarded a US$62 billion contract by the US DoD[276] that includes 66 new F-16s at US$8 billion (~$9.28 billion in 2023) for Taiwan.[277]

QF-16
In September 2013, Boeing and the U.S. Air Force tested an unmanned F-16, with two US Air Force pilots controlling the airplane from the ground as it flew from Tyndall AFB over the Gulf of Mexico.[278][279][280]

The F-16 has been involved in over 670 hull-loss accidents as of January 2020.[295][296]
On 8 May 1975, while practicing a 9-g aerial display maneuver with the second YF-16 (tail number 72-1568) at Fort Worth, Texas, prior to being sent to the Paris Air Show, one of the main landing gears jammed. The test pilot, Neil Anderson, had to perform an emergency gear-up landing and chose to do so in the grass, hoping to minimize damage and avoid injuring any observers. The aircraft was only slightly damaged, but because of the mishap, the first prototype was sent to the Paris Air Show in its place.[297]
On 15 November 1982, while on a training flight outside Kunsan Air Base in South Korea, USAF Captain Ted Harduvel died when he crashed inverted into a mountain ridge. In 1985, Harduvel's widow filed a lawsuit against General Dynamics claiming an electrical malfunction, not pilot error, as the cause; a jury awarded the plaintiff $3.4 million in damages. However, in 1989, the U.S. Court of Appeals ruled the contractor had immunity to lawsuits, overturning the previous judgment. The court remanded the case to the trial court "for entry of judgment in favor of General Dynamics".[298] The accident and subsequent trial was the subject of the 1992 film Afterburn.[299][300]
On 23 March 1994, during a joint Army-Air Force exercise at
C-141 that was being boarded by US Army paratroopers. This accident resulted in 24 fatalities and at least 100 others injured.[301] It has since been known as the "Green Ramp disaster".[302]
On 15 September 2003, a
Mountain Home AFB, Idaho. Captain Christopher Stricklin attempted a "split S" maneuver based on an incorrect mean-sea-level altitude of the airfield. Climbing to only 1,670 ft (510 m) above ground level instead of 2,500 ft (760 m), Stricklin had insufficient altitude to complete the maneuver, but was able to guide the aircraft away from spectators and ejected less than one second before impact. Stricklin survived with only minor injuries; the aircraft was destroyed. USAF procedure for demonstration "Split-S" maneuvers was changed, requiring both pilots and controllers to use above-ground-level (AGL) altitudes.[303][304]
On 26 January 2015, a Greek F-16D crashed while performing a NATO training exercise in Albacete, Spain. Both crew members and nine French soldiers on the ground died when it crashed in the flight line, destroying or damaging two Italian AMXs, two French Alpha jets, and one French Mirage 2000.[305][306] Investigations suggested that the accident was due to an erroneous rudder setting that was caused by loose papers in the cockpit.[307]
On 7 July 2015, an F-16CJ
Cessna 150M over Moncks Corner, South Carolina, U.S. The pilot of the F-16 ejected safely, but both people in the Cessna were killed.[308]
On 11 October 2018, an F-16 MLU from the 2nd Tactical Wing of the Belgian Air Component, on the apron at Florennes Air Station, was hit by a gun burst from a nearby F-16, whose cannon was fired inadvertently during maintenance. The aircraft caught fire and was burned to the ground, while two other F-16s were damaged and two maintenance personnel were treated for aural trauma.[309]
On 11 March 2020, a Pakistani F-16AM (Serial No. 92730) of the
Wing Commander Noman Akram, who was also the Commanding Officer of the No. 9 Squadron "Griffins", lost his life. A board of inquiry ordered by the Pakistan Air Force later revealed that the pilot had every chance to eject but opted not to and tried his best to save the aircraft and avoid civilian casualties on the ground. Videos taken by locals on the ground show his F-16AM crashing into some woods. He was hailed a hero by Pakistanis while also gaining some attention internationally.[310]
On 6 May 2023, a U.S. Air Force F-16C of the 8th Fighter Wing crashed in a field near Osan Air Base in South Korea during a daytime training sortie. The pilot safely ejected from the aircraft.[311][importance?]
On 8 May 2024, an F-16C of the Republic of Singapore Air Force crashed during takeoff within Tengah Air Base. The pilot successfully ejected from the aircraft without major injuries.[312] The cause was later identified to be from the malfunction of two of the three primary pitch rate gyroscopes on the aircraft. This was noted to be a "rare occurrence" by Lockheed Martin due to the concurrent failure of the two independent pitch rate gyroscopes giving similar inputs which caused the digital flight control computer to reject inputs from the correctly functioning pitch rate gyroscope and the backup pitch rate gyroscope when it was activated by the rejection of a primary pitch rate gyroscope.[313]
As newer variants have entered service, many examples of older F-16 models have been preserved for display worldwide, particularly in Europe and the United States.
