The '''Lockheed F-117 Nighthawk''' is an officially retired American single-seat, subsonic, [[Twinjet|twin-engine]]d, [[stealth aircraft|stealth]] [[attack aircraft]] developed by [[Lockheed Corporation|Lockheed]]'s secretive [[Skunk Works]] division and operated by the [[United States Air Force]] (USAF). It was the first operational aircraft to be designed with [[stealth technology]]. 

Work on what would become the F-117 commenced in the 1970s as a means of countering increasingly sophisticated [[Soviet]] [[surface-to-air missile]]s (SAMs). During 1976, the [[Defense Advanced Research Projects Agency]] (DARPA) issued Lockheed a contract to produce the ''[[Lockheed Have Blue|Have Blue]]'' technology demonstrator, the test data from which validated the concept. On 1 November 1978, Lockheed decided to proceed with the F-117 development program. A total of five prototypes were produced; the first of which performed its [[maiden flight]] in 1981 at [[Groom Lake, Nevada]]. The first production F-117 was delivered in 1982, and its [[initial operating capability]] was achieved in October 1983. All aircraft were initially based at [[Tonopah Test Range Airport]], Nevada.

The aircraft's [[faceting|faceted]] shape (made from two-dimensional flat surfaces) heavily contributes to its relatively low [[radar cross-section]] of about {{Convert|0.001|m2|sigfig=3|abbr=on}}. To minimize its [[infrared signature]], it has a non-circular [[exhaust system|tail pipe]] that mixes hot exhaust with cool ambient air and lacks [[afterburner]]s; it is also restricted to [[Subsonic flight|subsonic]] speeds as breaking the [[sound barrier]] would produce an obvious [[sonic boom]] that would increase both its acoustic and infrared footprints. While commonly referred to as the "Stealth Fighter", the aircraft was designed and employed as a dedicated [[attack aircraft]], and indeed its performance in [[air combat maneuvering]] was less than that of most contemporary fighters. The F-117 is equipped with integrated sophisticated digital navigation and attack systems, targeting being achieved via a [[thermal imaging]] [[infrared]] system and a [[laser rangefinder]]/[[laser designator]]. It is aerodynamically unstable in all three [[aircraft principal axes]] and thus requires constant flight corrections via a [[fly-by-wire]] (FBW) flight system to maintain controlled flight.

Even in the years following its entry to service, the F-117 was a [[black project]], its existence being denied by USAF officials. On 10 November 1988, the F-117 was publicly acknowledged for the first time. Its first combat mission was flown during the [[United States invasion of Panama]] in 1989. The last of 59 production F-117s were delivered on 3 July 1990. The F-117 was widely publicized for its role in the [[Gulf War]] of 1991, having flown around 1,300 sorties and scored direct hits on what the US military described as 1,600 high-value targets in Iraq. F-117s also participated in [[Yugoslav Wars|the conflict]] in [[Serbia and Montenegro|Yugoslavia]], during which [[1999 F-117A shootdown|one was shot down]] by a SAM in 1999. It was also active during [[Operation Enduring Freedom]] in 2001 and [[Iraq War|Operation Iraqi Freedom]] in 2003. The USAF retired the F-117 in 2008, primarily due to the fielding of the [[Lockheed Martin F-22 Raptor|F-22 Raptor]].<ref name="Miller 44" /> Despite the type's official retirement, a portion of the F-117 fleet has been kept in airworthy condition, and some have been observed flying since being retired from combat.<ref name=PM_2020_03-19>{{cite web |url= https://www.popularmechanics.com/military/aviation/a31784615/f-117-star-wars-canyon/ |title= A Rare F-117A Stealth Fighter Flies Over 'Star Wars Canyon |publisher= [[Popular Mechanics]] |date= 19 March 2020}}</ref> It has been flown by the US Air Force for research and development, testing, and training purposes.

=== Background and ''Have Blue'' ===
{{main|Lockheed Have Blue}}

In 1936, [[Robert Watson Watt]], the British [[radar]] pioneer, noted that measures to reduce an object's [[radar cross-section]] (RCS) could be used to evade radar detection.<ref name= "bomber 277">Gunston and Gilchrist 1993, p. 277.</ref> In 1962, [[Pyotr Ufimtsev]], a [[:Soviet Union|Soviet]] mathematician, published a seminal paper titled ''Method of Edge Waves in the Physical Theory of Diffraction'' in the journal of the Moscow Institute for Radio Engineering, in which he showed that the strength of the radar return from an object is related to its edge configuration, not its size.<ref name="dtic" /> Ufimtsev was extending theoretical work published by the German physicist [[Arnold Sommerfeld]].<ref name="Centennial" /><ref name="dtic" />{{rp|xiii}}<ref name="filling" /> Ufimtsev demonstrated that he could calculate the RCS across a wing's surface and along its edge. The obvious and logical conclusion was that even a large aircraft could reduce its radar signature by exploiting this principle. However, the resulting design would make the aircraft [[Relaxed stability|aerodynamically unstable]], and the state of computer technology in the early 1960s could not provide the kinds of flight computers which would later allow aircraft such as the F-117 and [[Northrop Grumman B-2 Spirit|B-2 Spirit]] to stay airborne. By the 1970s, when Lockheed analyst Denys Overholser found Ufimtsev's paper, computers and software had advanced significantly, and the stage was set for the development of a stealth airplane.<ref name="Advent" /><ref name="crickmore 14"/>

[[File:F-117 Grey Dragon.jpg|thumb|F-117A painted in "Gray Dragon" experimental camouflage scheme|alt=Aircraft parked inside an open hangar]]
The F-117 was conceived after the [[Vietnam War]], where increasingly sophisticated Soviet [[surface-to-air missile|SAMs]] had downed heavy bombers.<ref name="crickmore 9">Crickmore and Crickmore 2003, p. 9.</ref> The heavy losses inflicted by Soviet-made SAMs upon the [[Israeli Air Force]] in the [[Yom Kippur War|1973 Yom Kippur war]] also contributed to a 1974 [[Defense Science Board]] assessment that in case of a conflict in Central Europe, air defenses would likely prevent [[NATO]] air strikes on targets in Eastern Europe.<ref name=":0">{{Cite web |last=Sweetman |first=Bill |date=January 2008 |title=Unconventional Weapon |url=https://www.airspacemag.com/military-aviation/unconventional-weapon-23371597/ |access-date=22 November 2020 |website=[[Air & Space Magazine]] |language=en}}</ref>

=== ''Senior Trend'' ===
The decision to produce the F-117 was made on 1 November 1978, and a contract was awarded to Lockheed Advanced Development Projects, popularly known as the Skunk Works, in [[Burbank, California]].<ref name="rich1" /><ref name="crickmore 25">Crickmore and Crickmore 2003, p. 25.</ref> The program was led by [[Ben Rich (engineer)|Ben Rich]], with Alan Brown as manager of the project.<ref name="crickmore 1011">Crickmore and Crickmore 2003, pp. 10-11.</ref><ref>{{cite web |url=https://www.youtube.com/watch?v=mzQPIlXe2H0 |archive-url=https://web.archive.org/web/20140313124234/http://www.youtube.com/watch?v=mzQPIlXe2H0 |archive-date=13 March 2014 |url-status=dead |title=YouTube |via=YouTube}}</ref> Rich called on Bill Schroeder, a Lockheed mathematician, and Overholser, a mathematician and radar specialist, to exploit Ufimtsev's work.

The first YF-117A, serial number ''79-10780'', made its maiden flight from Groom Lake ([[Area 51]]), Nevada, on 18 June 1981,<ref name="Goodall p.27" /><ref name= "bomber 279">Gunston and Gilchrist 1993, p. 279.</ref> only 31 months after the full-scale development decision.

The F-117 was secret for much of the 1980s. Many news articles discussed what they called an "[[F-19]]" stealth fighter, and the [[Testor Corporation]] produced a very inaccurate [[scale model]]. When an F-117 crashed in [[Sequoia National Forest]] in July 1986, killing the pilot and starting a fire, the USAF established [[restricted airspace]].<ref>{{cite web | url=https://www.youtube.com/watch?v=ruBeOIcKIdo&ab_channel=ForrestHaggertyChannel | title=F-117 Nighthawk Crash 1986.

All F-117 debris was replaced with remains of a [[F-101A Voodoo]] crash stored at Area 51. When another fatal crash in October 1987 occurred inside Nellis, the military again provided little information to the press.{{r|afmag-richelson}}

The USAF denied the existence of the aircraft until 10 November 1988, when Assistant Secretary of Defense [[J. Daniel Howard]] displayed a grainy photograph at a Pentagon press conference, disproving the many inaccurate rumors about the shape of the "F-19".<ref>{{Cite news |last1=Jr |first1=John H.

[[File:Lockheed F-117.ogg|thumb|thumbtime=32|right|F-117 flight demonstration]]
Five full-scale development<!-- (FSD) --> aircraft were built, designated "YF-117A".<ref name="designation-systems" /> The last of 59 production F-117s were delivered on 3 July 1990.<ref name="Goodall p.29" /><ref name="donald" /> As the USAF has stated, "Streamlined management by Aeronautical Systems Center, [[Wright-Patterson AFB]], [[Ohio]], combined breakthrough stealth technology with concurrent development and production to rapidly field the aircraft... The F-117A program demonstrates that a stealth aircraft can be designed for reliability and maintainability."<ref name="Nat_Museum_factsht" />

=== Designation ===
The operational aircraft was officially designated "F-117A".<ref name="dtic3" /><ref name= "bomber 277"/> Most modern U.S. military aircraft use [[1962 United States Tri-Service aircraft designation system|post-1962 designations]] in which the designation "F" is usually an [[Fighter aircraft|air-to-air fighter]], "B" is usually a [[bomber]], "A" is usually a ground-attack aircraft, etc. (Examples include the [[McDonnell Douglas F-15 Eagle|F-15]], the B-2, and the [[Grumman A-6 Intruder|A-6]].) The F-117 is primarily an attack aircraft,<ref name=eden_p240>{{harvnb|Eden|2004|p=240.}}</ref> so its "F" designation is inconsistent with the [[United States Department of Defense|Department of Defense]] system. This is an inconsistency that has been repeatedly employed by the USAF with several of its attack aircraft since the late 1950s, including the [[Republic F-105 Thunderchief]] and [[General Dynamics F-111 Aardvark]]. A televised documentary quoted project manager Alan Brown as saying that [[Robert J. Dixon]], a four-star USAF general who was the head of [[Tactical Air Command]], felt that the top-notch USAF fighter pilots required to fly the new aircraft were more easily attracted to an aircraft with an "F" designation for fighter, as opposed to a bomber ("B") or attack ("A") designation.<ref name="history" /><ref>{{cite web |url=https://www.youtube.com/watch?v=81S4W8rOCgo&t=1658s |url-status=dead |title=Modern Marvels S11E62 F117 |last=Moderns |date=13 April 2017 |via=YouTube |access-date=22 July 2018 |archive-date=8 March 2021 |archive-url=https://web.archive.org/web/20210308223809/https://www.youtube.com/watch?v=81S4W8rOCgo&t=1658s}}</ref> Early on, one potential air-to-air mission considered for the F-117 was to hunt down the Soviet [[Beriev A-50|A-50 "Mainstay"]] airborne warning and control system<!-- (AWACS) -->. However, this was not deemed to be effective and this mission was passed to the nascent [[Advanced Tactical Fighter]], which eventually became the [[Lockheed Martin F-22 Raptor|F-22 Raptor]].<ref name="WMOF_JB">{{cite AV media |url=https://www.youtube.com/watch?v=lltMfkj1yPU |title=F-117 Nighthawk and F-22 Raptor with Jim "JB" Brown, President & CEO National Test Pilot School |date=21 November 2022 |publisher=Western Museum of Flight |location=Torrance, California |access-date=30 June 2023 |people=[[James E. Brown III|Brown, James "JB"]]}}</ref>

The designation "F-117" seems to indicate that it was given an official designation prior to the 1962 U.S. Tri-Service Aircraft Designation System and could be considered numerically to be a part of the earlier [[Century Series]] of fighters. The assumption prior to the revealing of the aircraft to the public was that it would likely receive the F-19 designation, as that number had not been used, but no other aircraft were to receive a "100" series number following the F-111. Soviet fighters obtained by the U.S. via various means under the [[Constant Peg]] program<ref name="airforce-magazine" /> were given F-series numbers for their evaluation by U.S. pilots, and with the advent of the [[Teen Series]] fighters, most often Century Series designations.<ref name="Merlin_groom_2011_p32">Merlin 2011, p. 32.</ref>

As with other exotic military aircraft types flying in the southern Nevada area, such as captured fighters, an arbitrary radio call of "117" was assigned. This same radio call had been used by the enigmatic [[4477th Test and Evaluation Squadron]], also known as the "Red Hats" or "Red Eagles", that often had flown expatriated [[Mikoyan#List of MiG aircraft|MiG jet fighters]] in the area, but no relationship existed between the call and the formal F-19 designation then being considered by the USAF. Apparently, use of the "117" radio call became commonplace and when Lockheed released its first flight manual (i.e., the USAF "dash one" manual for the aircraft), F-117A was the designation printed on the cover.<ref name="Miller1990" />

== Design ==
[[File:F-117 Front View.jpg|thumb|Front view of an F-117|alt=Closeup view of the nose of a black jet, emphasizing the many angled-surfaces]]

When the USAF first approached Lockheed with the stealth concept, Skunk Works Director Kelly Johnson proposed a rounded design. He believed smoothly blended shapes offered the best combination of speed and stealth. However, his assistant, Ben Rich, showed that faceted-angle surfaces would provide a significant reduction in radar signature, and the necessary aerodynamic control could be provided with computer units. A May 1975 Skunk Works report, "Progress Report No. 2, High Stealth Conceptual Studies", showed the rounded concept that was rejected in favor of the flat-sided approach.<ref>{{cite web |url= http://www.airspacemag.com/military-aviation/secrets-skunk-works-180952122/?page=6 |title= Secrets of the Skunk Works – 'Little Harvey, Concept B' |first= Chad |last= Slattery |publisher= [[Air & Space/Smithsonian]]}}</ref><ref name="crickmore 1213">Crickmore and Crickmore 2003, pp. 12-13.</ref><ref name= "bomber 278">Gunston and Gilchrist 1993, p. 278.</ref> The resulting unusual design surprised and puzzled experienced pilots; a [[Royal Air Force]]<!-- (RAF) --> pilot who flew it as an [[exchange officer]] stated that when he first saw a photograph of the still-secret F-117, he "promptly giggled and thought [to himself] 'this clearly can't fly{{'"}}.<ref name="crickmore 856">Crickmore and Crickmore 2003, pp. 85-86.</ref>

The single-seat F-117 is powered by two nonafterburning [[General Electric F404]] turbofan engines. They were extensively modified to suit a stealth aircraft, such as to have a cooler operational temperature, and somewhat resembled a [[turbojet]], instead.<ref name= "bomber 2801">Gunston and Gilchrist 1993, pp. 280-281.</ref> The engine was redesigned to produce a minimum of mass thrust, which eased the task of designing a suitable inlet and nozzle. To obscure the engine from enemy radar, a conductive metal mesh grill was installed in the intake, while the exhaust gases were intentionally mixed with cool air to lower the thermal signature.<ref name= "bomber 281">Gunston and Gilchrist 1993, p. 281.</ref>

The aircraft is [[Aerial refueling|air refuelable]] and features a [[V-tail]]. The maximum speed is {{cvt|623|mph|km/h kn}} at high altitude, the maximum rate of climb is {{convert|2820|ft}} per minute, and the service ceiling is {{convert|43000|to|45000|ft}}.<ref>Dorr 2016, p. 315.</ref><ref name= "bomber 27980">Gunston and Gilchrist 1993, pp. 279-280.</ref> The cockpit was quite spacious, with ergonomic displays and controls, but the field of view was somewhat obstructed with a large blind spot to the rear.<ref>Nijboer 2016, p. 210.</ref>

=== Avionics ===
Early stealth aircraft were designed with a focus on minimal radar cross-section<!-- (RCS) --> rather than aerodynamic performance; because of this, the F-117 is aerodynamically unstable in all three [[aircraft principal axes]] and requires constant flight corrections from a fly-by-wire (FBW) flight system to maintain controlled flight.<ref name="janos 3046">Rich and Janos 1994, pp. 30–31, 46.</ref><ref name= "bomber 280">Gunston and Gilchrist 1993, p. 280.</ref> It is equipped with quadruple-redundant FBW flight controls. To lower development costs, the avionics, FBW systems, and other systems and parts were derived from the General Dynamics [[F-16 Fighting Falcon]], [[Boeing B-52 Stratofortress]], [[McDonnell Douglas F/A-18 Hornet]], and [[McDonnell Douglas F-15E Strike Eagle]].<ref name="crickmore 1415">Crickmore and Crickmore 2003, pp. 14-15.</ref> To maintain a high level of secrecy, components were often rerouted from other aircraft programs, ordered using falsified addresses and other details, while $3 million worth of equipment was removed from USAF storage without disclosing its purpose.<ref name="janos 46">Rich and Janos 1994, p. 46.</ref>

The aircraft is equipped with sophisticated navigation and attack systems integrated into a digital avionics suite. It navigates primarily by [[Global Positioning System|GPS]] and high-accuracy [[inertial navigation]].<ref name= "bomber 282">Gunston and Gilchrist 1993, p. 282.</ref> Missions are coordinated by an automated planning system that can automatically perform all aspects of an attack mission, including weapons release.<ref name="fas2" /> Targets are acquired by a [[thermal imaging]], [[infrared]] system, paired with a [[laser rangefinder]]/[[laser designator]] that finds the range and designates targets for [[laser-guided bomb]]s.

Typical weapons are a pair of [[GBU-10]], [[GBU-12]], or [[GBU-27]] laser-guided bombs, two [[BLU-109]] penetration bombs, or, after 2006, two [[Joint Direct Attack Munitions]] (JDAM) GPS/INS-guided stand-off bombs.<ref name="janos 26">Rich and Janos 1994, p. 26.</ref><ref>{{cite journal |last1=Enos |first1=James R. |title=Applying real system age to DoD systems |journal=Systems Engineering |date=May 2022 |volume=25 |issue=3 |pages=242–253 |doi=10.1002/sys.21614 |s2cid=246811908}}</ref>

=== Stealth ===
{{main|Stealth aircraft}}

The F-117 has an RCS around {{Convert|0.001|m2|sigfig=3|abbr=on}}.<ref name="richardson" /> Among the penalties for stealth are subsonic speeds to prevent frame heating, heat on the engine inlet and outlet prevent certain thrusting maneuvers, a very low [[Aspect ratio (wing)|wing aspect ratio]], and a high [[sweep angle]] (50°), needed to deflect incoming radar waves to the sides.<ref name=":0" /><ref name="richardson36"/><ref name="richardson51"/> With these design considerations and no [[afterburner]], the F-117 is limited to subsonic speeds. Additionally, to maintain its low observability, the F-117 was not equipped with radar; not only would an active radar be detectable through its emissions, but also an inactive radar antenna would also act as a reflector of radar energy.<ref>{{cite web |last= Holloway |first= Don |date= March 1996 |title=Stealth Secrets of the F-117 Nighthawk |url= https://www.historynet.com/stealth-secrets-of-the-f-117-nighthawk-mar-96-aviation-history-feature.htm |access-date= 19 January 2022 |website= Historynet.com |publisher= HistoryNet}}</ref> Whether it carries any radar detection equipment remained classified as of 2008.<ref name=":0" />

Its [[faceting|faceted]] shape (made from two-dimensional flat surfaces) resulted from the limitations of the 1970s-era computer technology used to calculate its RCS. Later [[supercomputer]]s made subsequent aircraft like the [[B-2 bomber]] made use curved surfaces while maintaining stealth possible, through the use of far more computational resources to perform the additional calculations.<ref name="rich4" /> The radio-wave absorbing materials<!-- (RAM) --> covering the F-117 weighed almost one ton and were held in place by glue.<ref>{{Cite web |date=August 17, 2021 |title=Stealth Aircraft Technology in the F-117 Nighthawk and Beyond |url=https://www.aerospaceutah.org/stealth-aircraft-technology-in-the-f-117-nighthawk-and-beyond/ |access-date=December 16, 2024 |website=Hill Aerospace Museum}}</ref> The gaps between the sheets are filled with a kind of [[putty]] material called "butter".<ref name=":0" /><ref name="crickmore 2728">Crickmore and Crickmore 2003, pp. 27-28.</ref>

An exhaust plume contributes a significant [[infrared signature|infrared (IR) signature]]. The F-117 reduces IR signature with a noncircular [[exhaust system|tail pipe]] (a slit shape) to minimize the exhaust cross-section and maximize the mixing of hot exhaust with cool, ambient air.<ref name="crickmore 1516">Crickmore and Crickmore 2003, pp. 15-16.</ref> The F-117 lacks afterburners, because the hot exhaust would increase the infrared signature, breaking the [[sound barrier]] would produce an obvious [[sonic boom]], and surface heating of the aircraft skin would also increase the IR footprint.

[[Passive radar|Passive (multistatic) radar]], [[bistatic radar]], and especially [[multistatic radar]] systems detect some stealth aircraft better than conventional [[monostatic radar]]s, since first-generation stealth technology (such as the F-117) reflects energy away from the transmitter's [[Line-of-sight propagation|line of sight]], effectively increasing the RCS in other directions, which the passive radars monitor.<ref name="Bistatic Radar Sets">{{cite web |url=http://www.radartutorial.eu/05.bistatic/bs04.en.html |title=Bistatic Radar Sets |publisher=Radartutorial.eu |access-date=16 December 2010}}</ref>

During the program's early years, from 1984 to mid-1992, the F-117 fleet was based at Tonopah Test Range Airport, Nevada, where it served under the 4450th Tactical Group; [[Air Combat Command]]'s only F-117A unit.<ref name=":2">{{Cite web |title=F-117A - Nighthawk |url=https://www.holloman.af.mil/About/Fact-Sheets/Display/Article/317344/f-117a-nighthawk/ |access-date=2024-02-26 |website=Holloman Air Force Base |language=en-US}}</ref> The unit was headquartered at Nellis Air Force Base.

The aircraft was operated in secret from Tonopah for almost a decade; after the Gulf War, all aircraft moved to Holloman in 1992, but its integration with the USAF's nonstealth "iron jets" occurred slowly. As one senior F-117 pilot later said: "Because of ongoing secrecy, others continued to see the aircraft as 'none of their business, a stand-alone system'."<ref name=":0" /> The F-117 and members of the 49th Fighter Wing were deployed to Southwest Asia on multiple occasions.

Much media attention was given to the bombing of telecommunications, water, and transportation infrastructure in Baghdad. Stealth bombers were used due to the perimeter of Baghdad being heavily defended with antiaircraft weapons. The bombings quickly became part of a propaganda battle, with media highlighting the killing of civilians and American claims that stealth bombing was highly effective at destroying military targets.<ref name="Arkin">{{cite journal |last1=Arkin |first1=William M. |title=Baghdad |journal=Airpower Journal |volume=11 |issue=1 |page=4}}</ref> Postwar records show that the F-117 had 18 times more targets per aircraft than their nonstealth peers.<ref>{{cite journal |last1=RENNER, US AIR force |first1=Major R.

Outside of Baghdad, the F-117 bombing was primarily used to destroy airfields, and it was used in conjunction with other air munitions. Overall, 42 F-117s dropped 2077 bombs in Desert Storm. This accounts for about a third of USAF guided bombing.<ref name="Arkin"/>

Early claims of the F-117's effectiveness were later found to be overstated.<ref name="nytimes" /> Initial reports of F-117s hitting 80% of their targets were later scaled back to "41–60%".<ref name="GAO/NSIAD-97-134" />{{rp|132}} On the first night, they failed to hit 40% of their assigned air-defense targets, including the Air Defense Operations Center in Baghdad, and eight such targets remained functional out of 10 that could be assessed.<ref name="GAO/NSIAD-97-134" />{{rp|136–137}} In their Desert Storm white paper, the USAF stated, "the F-117 was the only airplane that the planners dared risk over downtown Baghdad" and that this area was particularly well defended.

The first bombs dropped in the 2003 [[Iraq War|Operation Iraqi Freedom]] were from two F-117 on the [[Dora, Baghdad|Dora Farms]] in an attempt to assassinate [[Saddam Hussein]]. The F-117 was chosen to deliver a bunker buster payload because nearby Baghdad was heavily fortified with antiaircraft weapons, and US intelligence indicated Saddam Hussein's bunker was too reinforced for missiles.

=== Program closeout ===
The [[1999 F-117A shootdown|loss of an F-117 in Serbia]] caused the USAF to create a subsection of their existing weapons school to improve tactics. More training was done with other units, and the F-117 began to participate in [[Exercise Red Flag|Red Flag exercises]]. Though advanced for its time, the F-117's stealthy faceted airframe required a large amount of maintenance and was eventually superseded by streamlined shapes produced with [[computer-aided design]]. Other weapons systems began to take on the F-117's roles, such as the [[Lockheed Martin F-22 Raptor|F-22 Raptor]] gaining the ability to drop guided bombs.<ref name="Miller 44" >Miller 1990, p. 44.</ref> By 2005, the aircraft was used only for certain missions, such as if a pilot needed to verify that the correct target had been hit, or when minimal [[collateral damage]] was vital.<ref name=":0" /><ref name="filling">{{cite journal |last= Ireton |first= Colin T. |url= http://www.airpower.maxwell.af.mil/airchronicles/apj/apj06/fal06/ireton.html |title= Filling the Stealth Gap |journal= Air and Space Power Journal |date= Fall 2006 |archive-url= https://web.archive.org/web/20150928004837/http://www.airpower.maxwell.af.mil/airchronicles/apj/apj06/fal06/ireton.html |archive-date= 28 September 2015}}</ref>

The USAF had once planned to retire the F-117 in 2011, but Program Budget Decision 720 (PBD 720), dated 28 December 2005, proposed retiring it by October 2008 to free up an estimated $1.07&nbsp;billion<ref name="thehill" /> to buy more F-22s.<ref name="Topolsky" /> PBD 720 called for 10 F-117s to be retired in FY2007 and the remaining 42 in FY2008, stating that other USAF planes and missiles could stealthily deliver precision ordnance, including the [[Northrop Grumman B-2 Spirit|B-2 Spirit]], F-22, and [[AGM-158 JASSM|JASSM]].<ref name="archive7" /> The planned introduction of the multirole [[Lockheed Martin F-35 Lightning II|F-35 Lightning II]] also contributed to the retirement decision.<ref name="boston" />

In late 2006, the USAF closed the F-117 formal training unit<!-- (FTU) -->,<ref name="airforcetimes" /> and announced the retirement of the F-117.<ref name="Bates" /> The first six aircraft to be retired took their last flight on 12 March 2007 after a ceremony at Holloman AFB to commemorate the aircraft's career. [[Brigadier General]] [[David L.

Five aircraft were placed in museums, including the first four YF-117As and some remains of the F-117 shot down over Serbia. Through 2009, one F-117 had been scrapped; AF Serial No. 79-0784 was scrapped at the Palmdale test facility on 26 April 2008.

The [[United States Navy]] tested the F-117 in 1984, but determined it was unsuitable for [[Aircraft carrier|carrier]] use.<ref name="crickmorep2003">{{cite book |url=https://archive.org/details/f117nighthawk00cric/page/33 |title=Combat Legend: F-117 Nighthawk |publisher=Airlife |last=Crickmore |first=Paul |year=2003 |pages=[https://archive.org/details/f117nighthawk00cric/page/33 33, 48–49, 60] |isbn=1-84037-394-6}}</ref> In the early 1990s, Lockheed proposed an upgraded carrier-capable F-117 variant dubbed the "Seahawk" to the Navy as an alternative to the canceled A/F-X program. The unsolicited proposal was received poorly by the Department of Defense, which lacked interest in the single-mission capabilities on offer, particularly as it would take money away from the Joint Advanced Strike Technology program, which evolved into the [[Joint Strike Fighter]]. The F-117N would have differed from the land-based F-117 in several ways, such as the use of "elevators, a bubble canopy, a less sharply swept wing and reconfigured tail".<ref name="not_inter" /><ref name="f-117a9" /> It would also be re-engined with [[General Electric F414]] turbofans in place of the [[General Electric F404]]s. The aircraft would be optionally fitted with hardpoints, allowing for an additional {{convert|8000|lb|abbr=on}} of payload, and a new ground-attack radar with air-to-air capability. In that role, the F-117N could carry [[AIM-120 AMRAAM]] air-to-air missiles.<ref name="not_inter" /><ref name="new_f117n" />

=== F-117B ===
{{anchor|A/F-117X}}
After being rebuffed by the Navy, Lockheed submitted an updated proposal that included afterburning capability and a larger emphasis on the F-117N as a multimission aircraft, rather than just an attack aircraft.<ref name="new_f117n" /> To boost interest, Lockheed also proposed an F-117B land-based variant that shared most of the F-117N capabilities. This variant was proposed to the USAF and RAF.<ref name="international" /> Two RAF pilots formally evaluated the aircraft in 1986 as a reward for British help with the [[1986 United States bombing of Libya|American bombing of Libya]] that year. RAF exchange officers began flying the F-117 in 1987,{{r|crickmorep2003}} but the British declined an offer during the [[Presidency of Ronald Reagan|Reagan administration]] to purchase the aircraft.<ref name="rogoway20170103">{{Cite web |url=http://www.thedrive.com/the-war-zone/6779/reagan-invited-thatcher-to-join-the-top-secret-f-117-program |title=Reagan Invited Thatcher To Join The Top Secret F-117 Program |last=Rogoway |first=Tyler |date=3 January 2017 |website=The Drive}}</ref> This renewed F-117N proposal was also known as the ''A/F-117X''.<ref name="aerospace" /> Neither the F-117N nor the F-117B were ordered.

== Nicknames ==
{{anchor|Goblin|Wobblin Goblin|Wobblin' Goblin|Wobbling Goblin|Wobbly Goblin|Shaba|Ghost}}
{{anchor|Shaba|Ghost}}
The aircraft's official name is "Night Hawk",<ref name="dtic10" /> with the alternative form "Nighthawk" also used.

As it prioritized stealth over aerodynamics, it earned the nickname "Wobblin' Goblin" due to its alleged instability at low speeds. However, F-117 pilots have stated the nickname is undeserved.<ref name="airforce-magazine11" /> "Wobblin' (or Wobbly) Goblin" is likely a holdover from the early ''Have Blue'' / ''Senior Trend'' (FSD) days of the project when instability was a problem. In the USAF, "Goblin" (without wobbly) persists as a nickname because of the aircraft's appearance. During [[Gulf War|Operation Desert Storm]], Saudis dubbed the aircraft "Shaba", which is Arabic for "Ghost".<ref name="defensemedianetwork" /><ref>{{cite web |website= Arabic.fi | url=https://arabic.fi/words/5508 | title=Ghost – an Arabic word}}</ref> Some pilots also called the airplane the "Stinkbug".<ref>{{cite web |url= https://www.f-117a.com/FAQ.html |url-status= dead |archive-url= https://web.archive.org/web/20010308151831/http://www.f-117a.com/FAQ.html |archive-date= 8 March 2001 |title= F-117A: Frequently Asked Questions}}</ref>

During the [[NATO bombing of Yugoslavia]] in 1999 it picked up the nickname "Invisible" (Serbian Cyrillic "Невидљиви", Latin "Nevidljivi"). The name became ironic after it was shot down over Serbian airspace near Buđanovci, leading to the phrase "we didn't know it was invisible".<ref>Aronstein and Piccirillo 1997, {{page needed|date=September 2023}}.</ref>
