The LOCKHEED F-117 NIGHTHAWK is a single-seat, twin-engine stealth
attack aircraft that was developed by Lockheed\'s secretive Skunk
Works division and operated by the
United States Air Force
United States Air Force (USAF). The
F-117 was based on the Have Blue technology demonstrator.
The Nighthawk was the first operational aircraft to be designed
around stealth technology . Its maiden flight took place in 1981, and
the aircraft achieved initial operating capability status in 1983. The
Nighthawk was shrouded in secrecy until it was revealed to the public
in 1988. Sixty-four F-117s were built, 59 of which were production
versions, with the other five being demonstrators/prototypes.
The F-117 was widely publicized for its role in the Persian Gulf War
of 1991. Although it was commonly referred to as the "Stealth
Fighter", it was strictly an attack aircraft. F-117s took part in the
conflict in Yugoslavia , where one was shot down by a surface-to-air
missile (SAM) in 1999; it was the only Nighthawk to be lost in combat.

U.S. Air Force retired the F-117 in 2008, primarily due to the
fielding of the F-22 Raptor .

BACKGROUND AND HAVE BLUE
Lockheed Have Blue
Pyotr Ufimtsev , a 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.
Ufimtsev was extending theoretical work published by the German
Arnold Sommerfeld . Ufimtsev demonstrated that he could
calculate the radar cross-section 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
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 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 stealthy airplane.

The F-117 was born after combat experience in the
Vietnam War when
increasingly sophisticated Soviet surface-to-air missiles (SAMs)
downed heavy bombers. It was a black project , an ultra-secret
program for much of its life: very few people in the Pentagon knew the
program even existed, until the F-117s were revealed to the public in
1988. The project began in 1975 with a model called the "Hopeless
Diamond" (a wordplay on the
Hope Diamond because of its appearance).
The following year, the Defense Advanced Research Projects Agency
(DARPA) issued Lockheed
Skunk Works a contract to build and test two
Stealth Strike Fighters, under the code name "Have Blue ". These
subscale aircraft incorporated jet engines of the Northrop T-38A ,
fly-by-wire systems of the F-16 , landing gear of the A-10 , and
environmental systems of the C-130 . By bringing together existing
technology and components, Lockheed built two demonstrators under
budget, at $35 million for both aircraft, and in record time.
The maiden flight of the demonstrators occurred on 1 December 1977.
Although both aircraft were lost during the demonstration program,
test data proved positive. The success of Have Blue led the government
to increase funding for stealth technology . Much of that increase was
allocated towards the production of an operational stealth aircraft,
the Lockheed F-117A, under the program code name "Senior Trend".
The decision to produce the F-117A 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. The
program was led by
Ben Rich , with Alan Brown as manager of the
project. Rich called on Bill Schroeder, a Lockheed mathematician, and
Denys Overholser, a computer scientist, to exploit Ufimtsev's work.
The three designed a computer program called "Echo", which made it
possible to design an airplane with flat panels, called facets, which
were arranged so as to scatter over 99% of a radar's signal energy
"painting" the aircraft.
The first YF-117A, serial number 79-0780, made its maiden flight from
Groom Lake , Nevada, on 18 June 1981, only 31 months after the
full-scale development decision. The first production F-117A was
delivered in 1982, and operational capability was achieved in October
4450th Tactical Group
4450th Tactical Group stationed at
Nellis AFB , Nevada
were tasked with the operational development of the early F-117, and
between 1981 (prior to the arrival of the first models) and 1989 they
used LTV A-7 Corsair IIs for training, to bring all pilots to a common
flight training baseline and later as chase planes for F-117A tests.
The Air Force 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 secret "F-19". After the
announcement pilots could fly the F-117 during daytime and no longer
needed to be associated with the A-7, flying the T-38 supersonic
trainer for travel and training instead. In April 1990, two F-117
aircraft were flown into
Nellis Air Force Base , Nevada, arriving
during daylight and publicly displayed to a crowd of tens of
Five Full Scale Development (FSD) aircraft were built, designated
"YF-117A". The last of 59 production F-117s were delivered on 3 July
1990. Play media F-117 flight demonstration
As the Air Force has stated, "Streamlined management by Aeronautical
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."
The operational aircraft was officially designated "F-117A". Most
modern U.S. military aircraft use post-1962 designations in which the
designation "F" is usually an air-to-air fighter , "B" is usually a
bomber , "A" is usually a ground-attack aircraft, etc. (Examples
include the F-15 , the B-2 , and the A-6 .) The F-117 is primarily an
attack aircraft, so its "F" designation is inconsistent with the DoD
system. This is an inconsistency that has been repeatedly employed by
U.S. Air Force
U.S. Air Force with several of its attack aircraft since the late
1950s, including the
Republic F-105 Thunderchief
Republic F-105 Thunderchief and General Dynamics
F-111 Aardvark . A televised documentary quoted a senior member of the
F-117A development team as saying 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.
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
F-19 designation as that number had not been used.
However, there were no other aircraft 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 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.
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
4477th Test and Evaluation Squadron , also known as the "Red
Hats" or "Red Eagles", that often had flown expatriated MiG jet
fighters in the area, but there was no relationship to the call and
F-19 designation then being considered by the Air Force.
Apparently, use of the "117" radio call became commonplace and when
Lockheed released its first flight manual (i.e., the Air Force "dash
one" manual for the aircraft), F-117A was the designation printed on
Front view of an F-117
When the Air Force first approached Lockheed with the stealth
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 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,
which was rejected in favor of the flat-sided approach.
The resulting unusual design surprised and puzzled experienced
Royal Air Force
Royal Air Force pilot, who flew it as an exchange officer
while it was still a secret project, stated that when he first saw a
photograph of the F-117, he "promptly giggled and thought to 'this
clearly can't fly'". Early stealth aircraft were designed with a
focus on minimal radar cross-section (RCS) rather than aerodynamic
performance. Highly-stealth aircraft like the F-117 Nighthawk are
aerodynamically unstable in all three aircraft principal axes and
require constant flight corrections from a fly-by-wire (FBW) flight
system to maintain controlled flight. It is shaped to deflect radar
signals and is about the size of an F-15 Eagle.
The single-seat Nighthawk is powered by two non-afterburning General
Electric F404 turbofan engines. It is air refuelable and features a
V-tail . The maximum speed is 623 miles per hour (1,003 km/h) at high
altitude, the max rate of climb is 2,820 feet (860 m) per minute, and
service ceiling is 43,000 to 45,000 feet (13,000 to 14,000 m). The
cockpit was quite spacious, with ergonomic displays and controls, but
the field of view was somewhat obstructed, with a large blind spot to
It has quadruple-redundant fly-by-wire flight controls. To lower
development costs, the avionics, fly-by-wire systems, and other parts
were derived from the
General Dynamics F-16 Fighting Falcon
General Dynamics F-16 Fighting Falcon ,
McDonnell Douglas F/A-18 Hornet and McDonnell Douglas F-15E Strike
Eagle . The parts were originally described as spares on budgets for
these aircraft, to keep the F-117 project secret. Cockpit
The aircraft is equipped with sophisticated navigation and attack
systems integrated into a digital avionics suite. It navigates
GPS and high-accuracy inertial navigation . Missions are
coordinated by an automated planning system that can automatically
perform all aspects of an attack mission, including weapons release.
Targets are acquired by a thermal imaging infrared system, slaved to a
laser rangefinder /laser designator that finds the range and
designates targets for laser-guided bombs . The F-117A's split
internal bay can carry 5,000 pounds (2,300 kg) of ordnance. Typical
weapons are a pair of
GBU-12 , or
GBU-27 laser-guided bombs,
BLU-109 penetration bombs, or two Joint Direct Attack Munitions
(JDAMs ), a GPS/INS guided stand-off bomb.
The F-117 has a
Radar cross-section of about 0.001 m2 (0.0108 sq ft).
Among the penalties for stealth are lower engine thrust due to losses
in the inlet and outlet, a very low wing aspect ratio , and a high
sweep angle (50°) needed to deflect incoming radar waves to the
sides. With these design considerations and no afterburner , the
F-117 is limited to subsonic speeds.
The F-117A carries no radar, which lowers emissions and
cross-section, and whether it carries any radar detection equipment is
The F-117A's faceted shape (made from 2-dimensional flat surfaces)
resulted from the limitations of the 1970s-era computer technology
used to calculate its radar cross-section. Later supercomputers made
it possible for subsequent aircraft like the
B-2 bomber to use curved
surfaces while maintaining stealth, through the use of far more
computational resources to perform the additional calculations.
An exhaust plume contributes a significant infrared signature . The
F-117 reduces IR signature with a non-circular tail pipe (a slit
shape) to minimize the exhaust cross-sectional volume and maximize the
mixing of hot exhaust with cool ambient air. The F-117 lacks
afterburners , because the hot exhaust would increase the infrared
signature, and breaking the sound barrier would produce an obvious
sonic boom , as well as surface heating of the aircraft skin which
also increases the infrared footprint. As a result, its performance in
air combat maneuvering required in a dogfight would never match that
of a dedicated fighter aircraft. This was unimportant in the case of
this aircraft since it was designed to be a bomber.
Passive (multistatic) radar , bistatic radar and especially
multistatic radar systems detect some stealth aircraft better than
conventional monostatic radars , since first-generation stealth
technology (such as the F-117) reflects energy away from the
transmitter's line of sight , effectively increasing the radar cross
section (RCS) in other directions, which the passive radars monitor.

During the program's early years, from 1984 to mid-1992, the F-117A
fleet was based at
Tonopah Test Range Airport ,
Nevada , where it
served under the 4450th Tactical Group. Because the F-117 was
classified during this time, the unit was officially located at Nellis
Air Force Base , Nevada, and equipped with
A-7 Corsair II aircraft.
All military personnel were permanently assigned to Nellis AFB, but
most personnel and their families lived in Las Vegas. This required
commercial air and trucking to transport personnel between Las Vegas
and Tonopah each week. The 4450th was absorbed by the 37th Tactical
Fighter Wing in 1989. In 1992, the entire fleet was transferred to
Holloman Air Force Base ,
New Mexico , under the command of the 49th
Fighter Wing . This move also eliminated the
Key Air and American
Trans Air contract flights to Tonopah, which flew 22,000 passenger
trips on 300 flights from Nellis to Tonopah per month.
The F-117 reached initial operating capability status in 1983. The
Nighthawk's pilots called themselves "Bandits". Each of the 558 Air
Force pilots who have flown the F-117 has a Bandit number, such as
"Bandit 52", that indicates the sequential order of their first flight
in the F-117.
The F-117 has been used several times in war. Its first mission was
United States invasion of Panama in 1989. During that
invasion two F-117A Nighthawks dropped two bombs on Rio Hato airfield.
Gulf War in 1991, the F-117 flew approximately 1,300
sorties and scored direct hits on 1,600 high-value targets in Iraq
over 6,905 flight hours. Leaflet drops on Iraqi forces displayed the
F-117 destroying ground targets and warned "Escape now and save
yourselves". Initial claims of its effectiveness were later found to
be overstated. For instance it was claimed that the F-117 made up 2.5%
of Coalition tactical aircraft in Iraq and they attacked more than 40%
of the strategic targets; this ignored the fact that only 229
Coalition aircraft could drop and designate laser-guided bombs of
which 36 F-117 represented 15.7%, and only the USAF had the I-2000
bombs intended for hardened targets, so the F-117 represented 32% of
all coalition aircraft that could deliver such bombs. Initial reports
of F-117s hitting 80% of their targets were later scaled back to
"41-60%". On the first night, they failed to hit 40% of their
assigned air-defense targets, including the Air Defense Operations
Center in Baghdad, and 8 such targets remained functional out of 10
that could be assessed. In their Desert Storm white paper, the USAF
claimed that "the F-117 was the only airplane that the planners dared
risk over downtown Baghdad" and that this area was particularly well
defended. In fact, most of the air defenses were on the outskirts of
the city and many other aircraft hit targets in the downtown area,
with minimal casualties when they attacked at night like the F-117.
This meant they avoided the optically aimed AAA and infra-red SAMs
which were the biggest threat to Coalition aircraft.
The aircraft was operated in secret from Tonopah for almost a decade,
but after the
Gulf War the aircraft moved to Holloman in 1992 –
however its integration with the USAF's non-stealth "iron jets"
occurred slowly. As one senior F-117A pilot later said: Because of
ongoing secrecy others continued to see the aircraft as "none of their
business, a stand-alone system". The F-117A and the men and women of
49th Fighter Wing were deployed to Southwest Asia on multiple
occasions. On their first deployment, with the aid of aerial
refueling, pilots flew non-stop from Holloman to Kuwait, a flight of
approximately 18.5 hours – a record for single-seat fighters that

One F-117 (AF ser. no. 82-0806) was lost to enemy action. It was
downed during a mission against the Army of Yugoslavia on 27 March
Operation Allied Force
Operation Allied Force . At approximately 8:15 pm local
time, the aircraft was acquired by a fire control radar at a distance
of 13 km and an altitude of 8 km: SA-3s were then launched by a
Yugoslav version of the Soviet Isayev S-125 "Neva" (NATO name SA-3
"Goa") anti-aircraft missile system. The launcher was run by the
3rd Battalion of the
250th Air Defence Missile Brigade under the
command of Colonel
Zoltán Dani . According to Dani in a 2007
interview, his troops spotted the aircraft on radar when its bomb-bay
doors opened, raising its radar signature. One source states one of
the missiles detonated by its proximity fuze near the F-117. Dani
said he kept most of his missile sites intact by frequently moving
them, and had spotters looking for F-117s and other NATO aircraft. He
also stated that he oversaw the modification of his targeting radar to
improve its detection capability. Canopy of F-117 shot down in
Serbia in March 1999 at the
Museum of Aviation in Belgrade
After the explosion, the aircraft became uncontrollable, forcing the
pilot to eject. The pilot was recovered six hours later by a United
States Air Force Pararescue team. Photos show that the aircraft
struck the ground at low speed in an inverted position, and that the
airframe remained relatively intact. The Serbs invited Russian
personnel to inspect the aircraft's remains, compromising the then
25-year-old U.S. stealth technology. The F-117's pilot was initially
misidentified. Though the name "Capt Ken 'Wiz' Dwelle" was painted on
the canopy, it was revealed in 2007 that the pilot was Lt. Col. Dale
Zelko. The stealth technology from the downed F-117 may have been
acquired by Russia and China.
Some American sources state that a second F-117A was damaged during
the same campaign, allegedly on 30 April 1999; the aircraft returned
to base, but it supposedly never flew again.
LATER SERVICE AND RETIREMENT
Use of the aircraft as part of
Operation Allied Force
Operation Allied Force continued, and
it was later used in the Operation Enduring Freedom in 2001 and
Operation Iraqi Freedom
Operation Iraqi Freedom in 2003. It was operated by the U.S. Air
The loss 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-117A began to participate in 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 weapon systems began to take on the F-117's roles, such as the
F-22 Raptor gaining ability to drop guided bombs. 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.
The Air Force 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
billion to buy more F-22s. PBD 720 called for 10 F-117s to be
retired in FY2007 and the remaining 42 in FY2008, stating that other
Air Force planes and missiles could stealthily deliver precision
ordnance, including the B-2 Spirit , F-22 and JASSM . The planned
introduction of the multirole F-35 Lightning II also contributed to
the retirement decision.
In late 2006, the Air Force closed the F-117 formal training unit
(FTU), and announced the retirement of the F-117. The first six
aircraft to be retired made their last flight on 12 March 2007 after a
ceremony at Holloman AFB to commemorate the aircraft's career.
David L. Goldfein , commander of the 49th Fighter
Wing , said at the ceremony, "With the launch of these great aircraft
today, the circle comes to a close – their service to our nation's
defense fulfilled, their mission accomplished and a job well done. We
send them today to their final resting place – a home they are
intimately familiar with – their first, and only, home outside of
Holloman." A pair of specially painted F-117 Nighthawks sporting

Unlike most other Air Force aircraft that are retired to
Davis-Monthan AFB for scrapping, or dispersal to museums, most of the
F-117s were placed in "Type 1000" storage in their original hangars
Tonopah Test Range Airport . At Tonopah, their wings were
removed and the aircraft are stored in their original
climate-controlled hangars. The decommissioning occurred in eight
phases, with the operational aircraft retired to Tonopah in seven
waves beginning on 13 March 2007, and ending with the last wave's
arrival on 22 April 2008. Four aircraft were kept flying beyond
April by the
410th Flight Test Squadron
410th Flight Test Squadron at Palmdale for flight test.
By August, two were remaining. The last F-117 (AF Serial No. 86-0831)
left Palmdale to fly to Tonopah on 11 August 2008. With the last
aircraft retired, the 410th was inactivated in a ceremony on 1 August
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 has been scrapped. F-117 AF Serial No. 79-0784 was
scrapped at the Palmdale test facility on 26 April 2008. It was the
last F-117 at Palmdale and was scrapped to test an effective method
for destroying F-117 airframes. Although officially retired, the
F-117 fleet remains intact, and photos show the aircraft carefully
mothballed. F-117s have been spotted flying in the Nellis Bombing
Range as recently as July 2015. Some of the aircraft are flown
Congress had declared that all F-117s mothballed from 30 September
2006 onwards to be maintained "in a condition that would allow recall
of that aircraft to future service" as part of the 2007 National
Defense Authorization Act. By April 2016, lawmakers appeared ready to
"remove the requirement that certain F-117 aircraft be maintained in a
condition that would allow recall of those aircraft to future
service," which would move them from storage to the aerospace
maintenance and regeneration yard in Arizona to be scavenged for
hard-to-find parts, or completely disassembled.
United States Navy
United States Navy tested the F-117 in 1984 but determined it was
not suitable for carrier use. In the early 1990s, Lockheed proposed
an upgraded, carrier-capable variant of the F-117 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 had little interest in the single mission capabilities of such
an aircraft, particularly as it would take money away from the Joint
Advanced Strike Technology program, which evolved into the Joint
Strike Fighter . The new aircraft would have differed from the
land-based F-117 in several ways, including the addition "of
elevators, a bubble canopy, a less sharply swept wing and reconfigured
tail". The "N" variant would also be re-engined to use General
Electric F414 turbofans instead of the older General Electric F404s .
The aircraft would be optionally fitted with hardpoints, allowing for
an additional 8,000 lb (3,600 kg) 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.
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 multi-mission aircraft, rather than just an attack
aircraft. 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 the
Royal Air Force
Royal Air Force . Several
RAF exchange officers flew the F-117 during its service, two RAF
pilots formally evaluated the aircraft in 1986 as a reward for British
help with the American bombing of Libya that year, and the British
declined an offer during the
Reagan administration to purchase the
aircraft. ) This renewed F-117N proposal was also known as the
A/F-117X. Neither the F-117N nor the F-117B was ordered.

* F-117, AF Ser. No. 81-0793, was lost on 14 September 1997 during
an airshow at
Martin State Airport / Warfield Air National Guard Base
Baltimore , Maryland. The aircraft suffered a catastrophic wing
failure, resulting in the port wing completely separating from the
fuselage. The aircraft was destroyed on impact. The pilot ejected
safely. The cause was determined to be missing wing bolts.
AIRCRAFT ON DISPLAY
79-10781 Scorpion 2 at the National Museum of the United States
Air Force YF-117A
* 79-10780 Scorpion 1 – on pedestal display on Nellis Boulevard,
at the entrance to
Nellis Air Force Base ,
115°3′33.28″W / 36.2272222°N 115.0592444°W /
36.2272222; -115.0592444 ). It was put in place 16 May 1992, the first
F-117 to be made a gate guardian.
* 79-10781 Scorpion 2 – National Museum of the United States Air
Wright-Patterson Air Force Base
Wright-Patterson Air Force Base outside Dayton,
Ohio . It was
delivered to the museum on 17 July 1991.
* 79-10782 Scorpion 3 –
Holloman Air Force Base ,
New Mexico . It
was repainted to resemble the first F-117A used to drop weapons in
combat. This aircraft was used for acoustics and navigation system
testing. While wearing a flag painted on its bottom surface, this
aircraft revealed the type's existence to high-ranking officials at
Groom Lake on 14 December 1983, the first semi-public unveiling of the
aircraft. It was placed on display at Holloman AFB on 5 April 2008.
* 79-10783 Scorpion 4 – It had been previously on display at the
Blackbird Airpark Museum at Air Force
Plant 42 , Palmdale, California
. In June 2012, Scorpion 4 was transported from Blackbird Airpark to
Edwards AFB for restoration work; it is planned for the aircraft to be
displayed at the
Air Force Flight Test Center
Air Force Flight Test Center Museum .
* 82-0806 Something Wicked – shot down over Serbia; the remains
are displayed at the
Museum of Aviation in Belgrade close to Belgrade
Nikola Tesla Airport .
The aircraft's official name is "Night Hawk", however the
alternative form "Nighthawk" is frequently 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.
"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
Operation Desert Storm
Operation Desert Storm ,
Saudis dubbed the aircraft "Shaba", which is Arabic for "Ghost".

March, was a major blow to the US Air Force. The aircraft was special:
an F-117 Nighthawk stealth bomber that should have been all but
invisible to the Serbian air defences. And this certainly wasn't a
fluke—a few nights later, Serb missiles damaged a second F-117."
