The fighter has a single turbofan engine, an internal M61 Vulcan cannon and 11 hardpoints . Although officially named "Fighting Falcon",

279-557: A 30% greater air-to-air detection range and a 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. The F-16E/F

372-402: A NACA 64A-204 airfoil was selected; the camber is adjusted by leading-edge and trailing edge flaperons linked to a digital flight control system regulating the flight envelope . The F-16 has a moderate wing loading, reduced by fuselage lift. The vortex lift effect is increased by leading-edge extensions, known as strakes. Strakes act as additional short-span, triangular wings running from

465-521: A competitor to Northrop Grumman's AN/APG-68 and AN/APG-80 for the F-16. 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). The initial powerplant selected for the single-engined F-16 was the Pratt & Whitney F100-PW-200 afterburning turbofan , a modified version of

558-460: A deal totaling $ 4.5 billion . F-16s were also used in their ground-attack role for strikes against targets in Lebanon. IAF F-16s participated in the 2006 Lebanon War and the 2008–09 Gaza War . During and after the 2006 Lebanon war, IAF F-16s shot down Iranian -made UAVs launched by Hezbollah , using Rafael Python 5 air-to-air missiles. On 10 February 2018, an Israeli Air Force F-16I

651-633: A fixed-price upgrade package for foreign users. CAPES was not included in the Pentagon's 2015 budget request. 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. In 2014, the USAF issued a RFI to SLEP 300 F-16 C/Ds. To make more room for assembly of its newer F-35 Lightning II fighter aircraft, Lockheed Martin moved

744-403: A high AOA inducing a stall. The limiters also prevent maneuvers that would exert more than a 9- g load. 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,

837-529: A high-PRF pulse-Doppler track mode to provide Interrupted Continuous Wave guidance for semi-active radar homing (SARH) missiles like the AIM-7 Sparrow. Block 50/52 F-16s initially used the more reliable APG-68(V)5 which has a programmable signal processor employing Very High Speed Integrated Circuit (VHSIC) technology. The Advanced Block 50/52 (or 50+/52+) is equipped with the APG-68(V)9 radar, with

930-416: A high-speed taxi test on 20 January 1974. While gathering speed, a roll-control oscillation caused a fin of the port-side wingtip-mounted missile and then the starboard stabilator to scrape the ground, and the aircraft then began to veer off the runway. The test pilot, Phil Oestricher , decided to lift off to avoid a potential crash, safely landing six minutes later. The slight damage was quickly repaired and

1395-562: A production line for the KF-16 program, producing 140 Block 52s from the mid-1990s to mid-2000s (decade). If India had selected the F-16IN for its Medium Multi-Role Combat Aircraft procurement, a sixth F-16 production line would have been built in India. In May 2013, Lockheed Martin stated there were currently enough orders to keep producing the F-16 until 2017. One change made during production

1488-571: A single digital display. 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. 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. Lockheed Martin responded to talk of CAPES cancellation with

1581-583: A successful all-weather multirole aircraft with over 4,600 built since 1976. 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 , which became part of Lockheed Martin after a 1995 merger with Martin Marietta . The F-16's key features include a frameless bubble canopy for enhanced cockpit visibility,

1674-457: A way as to produce the desired result without inducing control loss. The FLCC conducts thousands of measurements per second on the aircraft's flight attitude to automatically counter deviations from the pilot-set flight path. The FLCC further incorporates limiters governing movement in the three main axes based on attitude, airspeed, and angle of attack (AOA)/ g ; these prevent control surfaces from inducing instability such as slips or skids , or

1767-484: A weapons mix. More recent versions support the AIM-120 AMRAAM , and US aircraft often mount that missile on their wingtips to reduce wing flutter . 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

1860-466: Is an obstruction to a pilot's forward vision. The F-16's ACES II 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. Subsequent U.S. fighters have adopted more modest tilt-back angles of 20°. Because of

During the late 1980s and 1990s, Turkish Aerospace Industries (TAI) produced 232 Block 30/40/50 F-16s on a production line in Ankara under license for the Turkish Air Force . TAI also produced 46 Block 40s for Egypt in the mid-1990s and 30 Block 50s from 2010 onwards. Korean Aerospace Industries opened

3069-564: 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 . 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

3162-780: The wing root (the junction with the fuselage) to a point further forward on the fuselage. Blended into the fuselage and along the wing root, the strake generates a high-speed vortex that remains attached to the top of the wing as the angle of attack increases, generating additional lift and allowing greater angles of attack without stalling. Strakes allow a smaller, lower- aspect-ratio wing, which increases roll rates and directional stability while decreasing weight. Deeper wing roots also increase structural strength and internal fuel volume. Early F-16s could be armed with up to six AIM-9 Sidewinder heat-seeking short-range air-to-air missiles (AAM) by employing rail launchers on each wingtip, as well as radar-guided AIM-7 Sparrow medium-range AAMs in

3255-415: The " vortex lift " phenomenon could be harnessed by highly swept wing configurations to reach higher angles of attack , using leading edge vortex flow off a slender lifting surface. As the F-16 was being optimized for high combat agility, GD's designers chose a slender cropped-delta wing with a leading-edge sweep of 40° and a straight trailing edge. To improve maneuverability, a variable-camber wing with

3348-510: 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%. 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.

3906-413: The F-16 gains positive stability because of aerodynamic changes. 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) fly-by-wire (FBW) flight control system (FLCS). The flight control computer (FLCC) accepts pilot input from the stick and rudder controls and manipulates the control surfaces in such

3999-513: 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. 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. One key upgrade has been an auto-GCAS ( Ground collision avoidance system ) to reduce instances of controlled flight into terrain . Onboard power and cooling capacities limit

4092-614: The F-16 production from Fort Worth, Texas to its plant in Greenville, South Carolina . 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. A gap in orders made it possible to stop production during the move; after completing orders for

4185-426: The F-16's cockpit is the exceptional field of view. The single-piece, bird-proof polycarbonate bubble canopy provides 360° all-round visibility, with a 40° look-down angle over the side of the aircraft, and 15° down over the nose (compared to the common 12–13° of preceding aircraft); the pilot's seat is elevated for this purpose. Additionally, the F-16's canopy omits the forward bow frame found on many fighters, which

4278-529: The F-16A/B had monochrome cathode-ray tube (CRT) displays; replaced by color liquid-crystal displays on the Block 50/52. The Mid-Life Update (MLU) introduced compatibility with night-vision goggles (NVG). The Boeing Joint Helmet Mounted Cueing System (JHMCS) is available from Block 40 onwards for targeting based on where the pilot's head faces, unrestricted by the HUD, using high- off-boresight missiles like

4371-454: 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

4464-748: The Fokker factory. Beginning in November 1977, Fokker-produced components were sent to Fort Worth for fuselage assembly, then shipped back to Europe for final assembly of EPAF aircraft at the Belgian plant on 15 February 1978; deliveries to the Belgian Air Force began in January 1979. The first Royal Netherlands Air Force aircraft was delivered in June 1979. In 1980, the first aircraft were delivered to

4557-538: The LWF into a serious acquisition program. NATO allies Belgium, Denmark, the Netherlands, and Norway were seeking to replace their F-104G Starfighter fighter-bombers . 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

4650-471: The Netherlands, and 72 for Norway. Two European production lines, one in the Netherlands at Fokker 's Schiphol-Oost facility and the other at SABCA's Gosselies plant in Belgium, would produce 184 and 164 units respectively. Norway's Kongsberg Vaapenfabrikk and Denmark's Terma A/S also manufactured parts and subassemblies for EPAF aircraft. European co-production was officially launched on 1 July 1977 at

4743-755: 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 . 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). The YF-16 design

4836-576: The YF-16 and YF-17 , respectively, with the first flights of both prototypes planned for early 1974. To overcome resistance in the Air Force hierarchy, the Fighter Mafia and other LWF proponents successfully advocated the idea of complementary fighters in a high-cost/low-cost force mix. 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

4929-506: The air forces of 25 other nations. As of 2024, it is the world's most common fixed-wing aircraft in military service, with 2,145 F-16s operational. US Vietnam War experience showed the need for air superiority fighters and better air-to-air training for fighter pilots. 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

5022-454: 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

In addition to active duty in the U.S. Air Force, Air Force Reserve Command , and Air National Guard units, the aircraft is also used by the U.S. Air Force Thunderbirds aerial demonstration team, the US Air Combat Command F-16 Viper Demonstration Team, and as an adversary/aggressor aircraft by the United States Navy . The F-16 has also been procured by

5208-436: The aircraft to return to straight and level flight 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 ,

5301-431: 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. Unlike the YF-17, which had hydromechanical controls serving as a backup to the FBW, General Dynamics took the innovative step of eliminating mechanical linkages from

5394-403: 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. The F-16 has a cropped- delta wing incorporating wing-fuselage blending and forebody vortex -control strakes ; a fixed-geometry, underslung air intake (with splitter plate ) to

5487-797: The capability for Over the Air Rekeying (OTAR). EPLRS uses the Army Data Distribution System version of the X.25 CCITT and IEEE 802.3 protocols to interface with Army Tactical Command and Control System (ATCCS). Situation Awareness Data Link (SADL), installed on USAF F-16 and A-10 fighters, coordinates with EPLRS for ground support missions. Each network is controlled by a Network Control Station (NCS), AN/TSQ-158. These have gone through several iterations. Downsized version to fit in HMMWV , first fielded in 1991.

5580-420: The control stick and rudder pedals to the flight control surfaces . 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." The quadruplex design permits " graceful degradation " in flight control response in that

5673-639: The fictional Colonial Viper starfighter from the television program Battlestar Galactica , which aired at the time the F-16 entered service. On 7 June 1975, the four European partners, now known as the European Participation Group , signed up for 348 aircraft at the Paris Air Show . This was split among the European Participation Air Forces (EPAF) as 116 for Belgium, 58 for Denmark, 102 for

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

5952-517: The fuselage. Two other locations under the fuselage are available for sensor or radar pods. 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. 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. Most aircraft are designed to have positive static stability, which induces

6045-725: 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

This contract was signed in June 2018, and the first planes rolled off the Greenville line in 2023. 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

6231-420: The loss of one channel renders the FLCS a "triplex" system. 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. The F-16's controls suffered from a sensitivity to static electricity or electrostatic discharge (ESD) and lightning . Up to 70–80% of the C/D models' electronics were vulnerable to ESD. A key feature of

6324-573: The loss was due to pilot error since the IAF determined the air crew did not adequately defend themselves. On 16 July 2024, the last single-seat F-16C Barak-1 (‘Lightning’ in Hebrew) were retired; the Israeli Air Force continue to use the F-16D Brakeet and F-16I Sufa two-seat variants. During the Soviet–Afghan War , PAF F-16As shot down between 20 and 30 Soviet and Afghan warplanes ; the political situation however resulted in PAF officially recognizing only 9 kills which were made inside Pakistani airspace. From May 1986 to January 1989, PAF F-16s from

6417-417: 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

6510-455: The official first flight occurred on time. The YF-16's first supersonic flight was accomplished on 5 February 1974, and the second YF-16 prototype first flew on 9 May 1974. This was followed by the first flights of Northrop's YF-17 prototypes on 9 June and 21 August 1974, respectively. During the fly-off, the YF-16s completed 330 sorties for a total of 417 flight hours; the YF-17s flew 288 sorties, covering 345 hours. Increased interest turned

6603-488: The pilot without obstructing the view; being able to keep their head "out of the cockpit" improves the pilot's situation awareness . Further flight and systems information are displayed on multi-function displays (MFD). The left-hand MFD is the primary flight display (PFD), typically showing radar and moving maps; the right-hand MFD is the system display (SD), presenting information about the engine, landing gear, slat and flap settings, and fuel and weapons status. Initially,

6696-402: 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. The F-16 was designed to be relatively inexpensive to build and simpler to maintain than earlier-generation fighters. The airframe

6789-472: The prime contract for FBCB2 in 1995. ESP (Engineering Solutions and Products) is now the prime contractor for the system. FBCB2 was first used in actual military operations in the former Yugoslavia in 1998. It played a key role in operations in Iraq and Afghanistan starting in 2003. Work has begun on plans to reach the level of nearly 160,000 tracking systems in the Army within a few years. The FBCB2 system, and

6882-416: The reactor for the creation of nuclear weapons . 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. In January 2000, Israel completed a purchase of 102 new F-16I aircraft in

6975-676: The scope of upgrades, which often involve the addition of more power-hungry avionics. 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; BAE lost the South Korean contract because of a price breach in November 2014. In 2012, the USAF assigned the total upgrade contract to Lockheed Martin. Upgrades include Raytheon's Center Display Unit, which replaces several analog flight instruments with

7068-427: 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. 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

7161-490: 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. Secretary McLucas announced that

7254-414: The single turbofan jet engine; a conventional tri-plane empennage arrangement with all-moving horizontal "stabilator" tailplanes; a pair of ventral fins beneath the fuselage aft of the wing's trailing edge; and a tricycle landing gear configuration with the aft-retracting, steerable nose gear deploying a short distance behind the inlet lip. There is a boom-style aerial refueling receptacle located behind

7347-425: The single-piece "bubble" canopy of the cockpit. Split-flap speedbrakes are located at the aft end of the wing-body fairing, and a tailhook is mounted underneath the fuselage. A fairing beneath the rudder often houses ECM equipment or a drag chute . Later F-16 models feature a long dorsal fairing along the fuselage's "spine", housing additional equipment or fuel. Aerodynamic studies in the 1960s demonstrated that

7440-482: The theory. 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. The Advanced Day Fighter concept, renamed F-XX , gained civilian political support under the reform-minded Deputy Secretary of Defense David Packard , who favored

7533-501: The time of the prototypes' fly-off, defining the relationship between the LWF and the F-15. The YF-16 was developed by a team of General Dynamics engineers led by Robert H. Widmer . The first YF-16 was rolled out on 13 December 1973. Its 90-minute maiden flight was made at the Air Force Flight Test Center at Edwards AFB , California, on 2 February 1974. Its actual first flight occurred accidentally during

7626-526: 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. On 13 January 1975, Secretary of the Air Force John L. McLucas announced the YF-16 as the winner of the ACF competition. The chief reasons given by

7719-450: Was accepted by the USAF on 6 January 1979. The aircraft entered USAF operational service with the 34th Tactical Fighter Squadron , 388th Tactical Fighter Wing , at Hill AFB in Utah, on 1 October 1980. 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 viper snake as well as to

7812-472: 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 m ), 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

7905-480: 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

7998-491: Was increased by 25% over the YF-16 by these modifications. The FSD F-16s were manufactured by General Dynamics in Fort Worth, Texas , at United States Air Force Plant 4 in late 1975; the first F-16A rolled out on 20 October 1976 and first flew on 8 December. The initial two-seat model achieved its first flight on 8 August 1977. The initial production-standard F-16A flew for the first time on 7 August 1978 and its delivery

8091-635: 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.) The Increased Performance Engine (IPE) program led to

8184-418: 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. The F-16 has a head-up display (HUD), which projects visual flight and combat information in front of

8277-408: Was placed so it was rearward of the nose but forward enough to minimize air flow losses and reduce aerodynamic drag . 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

8370-485: Was rolled into a new Air Combat Fighter (ACF) competition in an announcement by U.S. Secretary of Defense James 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. ACF also raised the stakes for GD and Northrop because it brought in competitors intent on securing what

8463-586: Was shot down in northern Israel when it was hit by a relatively old model S-200 (NATO name SA-5 Gammon) surface-to-air missile of the Syrian Air Defense Force. The pilot and navigator ejected safely in Israeli territory. 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. An Israel Air Force investigation determined on 27 February 2018 that

8556-572: 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. 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

8649-620: Was touted at the time as "the arms deal of the century". 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
