The Sikorsky UH-60 Black Hawk is a four-bladed, twin-engine, medium-lift utility helicopter manufactured
by Sikorsky Aircraft. Sikorsky submitted the S-70 design for the United States Army's Utility Tactical Transport
Aircraft System (UTTAS) competition in 1972. The Army designated the prototype as the YUH-60A and
selected the Black Hawk as the winner of the program in 1976, after a fly-off competition with the Boeing Vertol
YUH-61.
The UH-60A entered service with the U.S. Army in 1979, to replace the Bell UH-1 Iroquois as the Army's
tactical transport helicopter. This was followed by the fielding of electronic warfare and special operations
variants of the Black Hawk. Improved UH-60L and UH-60M utility variants have also been developed. Modified
versions have also been developed for theU.S. Navy, Air Force, and Coast Guard. In addition to U.S. Army
use, the UH-60 family has been exported to several nations. Black Hawks have served in combat during
conflicts in Grenada,Panama, Iraq, Somalia, the Balkans, Afghanistan, and other areas in the Middle East.

Development[edit]
Initial requirement[edit]
In the late 1960s, the United States Army began forming requirements for a helicopter to replace the UH-1
Iroquois, and designated the program as the Utility Tactical Transport Aircraft System (UTTAS). The Army also
initiated the development of a new, common turbine engine for its helicopters that would become the General
Electric T700. Based on experience in Vietnam, the Army required significant performance, survivability and
reliability improvements from both UTTAS and the new powerplant.[3] The Army released its UTTAS request for
proposals (RFP) in January 1972.[4] The RFP also included air transport requirements. Transport aboard the C-
130 limited the UTTAS cabin height and length.[5]
The UTTAS requirements for improved reliability, survivability and lower life-cycle costs resulted in features
such as dual-engines with improved hot and high altitude performance, and a modular design (reduced
maintenance footprint); run-drygearboxes; ballistically tolerant, redundant subsystems (hydraulic, electrical
and flight controls); crashworthy crew (armored) and troop seats; dual-stage oleo main landing gear;
ballistically tolerant, crashworthy main structure; quieter, more robustmain and tail rotor systems; and
a ballistically tolerant, crashworthy fuel system.[6]
Four prototypes were constructed, with the first YUH-60A flying on 17 October 1974. Prior to delivery of the
prototypes to the US Army, a preliminary evaluation was conducted in November 1975 to ensure the aircraft
could be operated safely during all testing.[7] Three of the prototypes were delivered to the Army in March 1976,
for evaluation against the rivalBoeing-Vertol design, the YUH-61A, and one was kept by Sikorsky for internal
research. The Army selected the UH-60 for production in December 1976. Deliveries of the UH-60A to the
Army began in October 1978 and the helicopter entered service in June 1979.[8]
UH-60A Black Hawks over Port Salinasduring the invasion of Grenada, 1983. The conflict saw the first use of the UH-60.
Upgrades and variations[edit]
After entering service, the helicopter was modified for new missions and roles, including mine laying and
medical evacuation. An EH-60 variant was developed to conduct electronic warfare and special operations
aviation developed the MH-60 variant to support its missions.[9]
Due to weight increases from the addition of mission equipment and other changes, the Army ordered the
improved UH-60L in 1987. The new model incorporated all of the modifications made to the UH-60A fleet as
standard design features. The UH-60L also featured more power and lifting capability with upgraded T700-GE-
701C engines and a stronger gearbox, both developed for the SH-60B Seahawk.[10] Its external lift capacity
increased by 1,000 lb (450 kg) to 9,000 lb (4,100 kg). The UH-60L also incorporated the automatic flight control
system (AFCS) from the SH-60 for better flight control due to handling issues with the more powerful engines.
[11] Production of the L-model began in 1989.[10]
UH-60s equipped with machine guns near An Najaf, Iraq in May 2005.
Development of the next improved variant, the UH-60M, was approved in 2001, to extend the service life of the
UH-60 design into the 2020s. The UH-60M incorporates upgraded T700-GE-701D engines and improved rotor
blades. It also features state of the art electronic instrumentation, flight controls and aircraft navigation control.
After the U.S. DoD approved low-rate initial production of the new variant,[12] manufacturing began in 2006,
[13] with the first of 22 new UH-60Ms delivered in July 2006.[14] After an initial operational evaluation, the Army
approved full-rate production and a five-year contract for 1,227 helicopters in December 2007.[15] By March
2009, 100 UH-60M helicopters had been delivered to the Army.[16]
In the 1 May 2011 operation that killed Osama bin Laden, it emerged that the160th Special Operations Aviation
Regiment, which operated the helicopters during the raid, used a highly modified version of the UH-60.
Features apparently include a modified tail section with extra blades on the tail rotor and other additions which
significantly lowered noise levels from that of conventional UH-60s. It also had low-observable technology
similar to that of F-117 that enabled it to evade Pakistan Air Force radars. The aircraft seemed to include
features like special high-tech materials, harsh angles, and flat surfaces, found only on sophisticated stealth
jets. This came to light only when one of the helicopters used in the operation crashed and was subsequently
destroyed except for its tail section.[17][18][Nb 1][19] Low observable versions of the Black Hawk have been studied
as far back as the mid-1970s.[20]
In September 2012, Sikorsky was awarded a Combat Tempered Platform Demonstration (CTPD) contract to
further improve the Black Hawk's durability and survivability. Sikorsky is to develop new technologies such as a
zero-vibration system, adaptive flight control laws, advanced fire management, a more durable main rotor, full-
spectrum crashworthiness, and damage tolerant airframe, then transition them to the helicopter. Improvements
to the Black Hawk are to continue in preparation for the Future Vertical Lift program that is to replace it.[21][22]
Design[edit]
UH-60A Black Hawk parked on flight line
The UH-60 features four-blade main and tail rotors, and is powered by twoGeneral Electric
T700 turboshaft engines.[23] The main rotor is fully articulated and has elastomeric bearings in the rotor head.
The tail rotor is canted and features a rigid crossbeam.[24] The helicopter has a long, low profile shape to meet
the Army's requirement for transporting aboard a C-130 Hercules, with some disassembly.[23] It can carry 11
troops with equipment, lift 2,600 lb (1,170 kg) of cargo internally or 9,000 lb (4,050 kg) of cargo (for UH-60L/M)
externally by sling.[15]
The Black Hawk helicopter series can perform a wide array of missions, including the tactical transport of
troops, electronic warfare, and aeromedical evacuation. A VIP version known as the VH-60N is used to
transport important government officials (e.g., Congress, Executive departments) with the helicopter's call sign
of "Marine One" when transporting the President of the United States.[25] In air assault operations it can move a
squad of 11 combat troops or reposition a 105 mm M119 howitzer with 30 rounds ammunition, and a four-man
crew in a single lift.[15] The Black Hawk is equipped with advanced avionics and electronics for increased
survivability and capability, such as the Global Positioning System.
A view of a UH-60 cockpit
The UH-60 can be equipped with stub wings at top of fuselage to carry fuel tanks or various armaments. The
initial stub wing system is called External Stores Support System (ESSS).[26] It has two pylons on each wing to
carry two 230 US gal (870 L) and two 450 US gal (1,700 L) tanks in total.[11] The four fuel tanks and associated
lines and valves form the external extended range fuel system (ERFS).[27] U.S. Army UH-60s have had their
ESSS modified into the crashworthy external fuel system (CEFS) configuration, replacing the older tanks with
up to four total 200 US gal (760 L) crashworthy tanks along with self-sealing fuel lines.[28] The ESSS can also
carry 10,000 lb (4,500 kg) of armament such as rockets, missiles and gun pods.[11][29] The ESSS entered service
in 1986. However it was found that with four fuel tanks it would obstruct the firing field of the door guns. To
alleviate the issue, the external tank system (ETS) with unswept stub wings to carry two fuel tanks was
developed.[11]
The unit cost varies with the version due to the varying specifications, equipment and quantities. For example,
the unit cost of the Army's UH-60L Black Hawk is $5.9 million while the unit cost of the Air Force HH-60G Pave
Hawk is $10.2 million.[30]
Operational history[edit]
United States[edit]
U.S. Army MH-60L during the Battle of Mogadishu in 1993
The UH-60 entered service with the U.S. Army's 101st Combat Aviation Brigade of the 101st Airborne
Division in June 1979.[31] The U.S. military first used the UH-60 in combat during the invasion of Grenada in
1983, and again in the invasion of Panama in 1989. During the Gulf War in 1991, the UH-60 participated in the
largest air assault mission in U.S. Army history with over 300 helicopters involved. Two UH-60s (89-26214 and
78-23015) were shot down, both on 27 February 1991, while performing Combat Search and Rescue of other
downed aircrews, an F-16C pilot and the crew of a MEDEVAC UH-1H that were shot down earlier that day.[32]
In 1993, Black Hawks featured prominently in the assault on Mogadishu in Somalia. Black Hawks also saw
action in the Balkans and Haiti in the 1990s.[11]U.S. Army UH-60s and other helicopters conducted many air
assault and other support missions during the 2003 invasion of Iraq. The UH-60 has continued to serve in
operations in Afghanistan and Iraq.[11]
The United States Border Patrol uses the UH-60 in its operations specifically along the southwest border. The
Black Hawk has been used by the Border Patrol to interdict the illegal entry of aliens into the U.S. and the
incursion of dangerous individuals. Additionally, the Border Patrol regularly uses the UH-60 in search and
rescue operations.
Highly modified H-60s were employed during the U.S. Special Forces operation that resulted in the death of
Osama bin Laden on 1 May 2011.[19][33] One such helicopter experienced mechanical trouble during the
operation and the team was forced to destroy it before departing in the other MH-60 and a backup MH-47
Chinook with bin Laden's remains. Two MH-47s were used for the mission to refuel the two MH-60s and as
backups.[34] Several media outlets have reported that Pakistani government has granted the Chinese military
access to the remains of the crashed 'stealth' UH-60 variant in Abbotabad.[35][36][37] Pakistan and China deny the
reports,[35][36] and the U.S. Government has not confirmed the Chinese access.[36]
Colombia[edit]
A Colombian Air Force UH-60L Arpía
Colombia first received UH-60s from the United States in 1987. TheColombian National Police, Colombian Air
Force, and Colombian Army use UH-60s to mobilize troops and supplies to places which are difficult to access
by ground for counter-insurgency (COIN) operations against drug and guerrilla organizations, as well as for
search & rescue and medical evacuation. Colombia also operates a militarized gunship version of the UH-60,
with stub wings, locally known as Arpía (English: Harpy).[38][39]
The Colombian Army became the first worldwide operator of the S-70i with Terrain Awareness and Warning
Capability (HTAWS) after taking delivery of the first two units on August 13, 2013.[40]
Israel[edit]
Israel Air Force UH-60 Yanshuf
The Israeli Air Force (IAF) received 10 surplus UH-60A Black Hawks from the United States in August 1994.
[41] Named Yanshuf (English: Owl) by the IAF,[42] the UH-60A began replacing Bell 212 utility helicopters of the
Israeli Defense Forces.[41] The IAF first used the UH-60s in combat during Operation "Grapes of Wrath" in April
1996, against the Hezbollah in southern Lebanon.
Mexico[edit]
The Mexican Air Force ordered its first two UH-60Ls in 1991 to transport special forces units and since then
purchased another 4 in 1994.[43] In July and August 2009, the Federal Police used UH-60s in attacks on drug
traffickers.[44][45] In August 2011, the Mexican Navy received three upgraded and navalized UH-60M.[46]
People's Republic of China[edit]
In December 1983, examples of the Aerospatiale AS-332 Super Puma, Bell 214ST SuperTransport and
Sikorsky S-70A-5 (N3124B) were airlifted to Lhasa for testing. These demonstrations included take-offs and
landings at altitudes to 17,000 feet and enroute operations to 24,000 feet. At the end of this testing,
the People's Liberation Army Air Force purchased 24 S-70C-2s. These S-70C-2s equipped with more powerful
GE T700-701A engines, for improved high-altitude performance.[47] While designated as civil variants of the S-
70 for export purposes, they are operated by the People's Liberation Army Air Force.
Taiwan (Republic of China)[edit]
Taiwan S-70C
Taiwan has operated S-70C-1/1A since the Republic of China Air Force received ten S-70C-1A and four S-
70C-1 Bluehawk helicopters in June 1986 for Search And Rescue.[48] Four further S-70C-6s were received in
April 1998. The ROC Navy received the first of ten S-70C(M)-1s in July 1990. 11 S-70C(M)-2s were received
beginning April 2000.[49] In January 2010, the US announced a Foreign Military Sale of 60 UH-60Ms to Taiwan
for the ROC Army.[50]
Sweden[edit]
Sweden requested 15 UH-60M helicopters by a Foreign Military Sale in September 2010.[51] On 18 May 2011,
Sikorsky announced the sale of 15 UH-60Ms to Sweden.[52] Helicopter deliveries began in January 2012.[53] In
March 2013 Swedish ISAF forces began using Black Hawks in Afghanistan for MEDEVAC purposes.[54] The
UH-60Ms are to be fully operational by 2017.[55]
Turkey[edit]
Turkey has operated the UH-60 during NATO deployments to Afghanistan and the Balkans. The UH-60 has
also been used in counter-terror/internal security operations.[citation needed]
The Black Hawk competed in the Turkish General Use Helicopter Tender against the AgustaWestland AW149.
Under this project Turkey intends to order up to 115 helicopters and produce many of them
indigenously. Turkish Aerospace Industries will be responsible for the final integration and assembly.[56][57] On
21 April 2011, Turkey announced the selection of Sikorsky's T-70 for the tender.[58][59][60]
Other and potential users[edit]
Brazilian Air Force UH-60L
The United Arab Emirates requested 14 UH-60M helicopters and associated equipment in September 2008
through a Foreign Military Sale.[61] It had received 20 UH-60Ls by November 2010.[62] Bahrain ordered 9 UH-
60Ms in 2007.[63][64]
Brazil received four UH-60L helicopters in 1997 for Brazilian Armypeacekeeping forces. It received 6 UH-60Ls
configured for special forces, and search and rescue use in 2008. It ordered 10 more UH-60Ls in 2009;
deliveries began in March 2011.[65]
In November 2011, it was reported that Sikorsky would sell 12 UH-60Ms to theRoyal Brunei Air Force.[66] On 12
June 2012, the U.S. Defense Security Cooperation Agency notified Congress that Qatar requested the
purchase 12 UH-60Ms, engines, and associated equipment.[67]
On 25 February 2013, the Indonesian Army announced interest to buy UH-60 Black Hawks as part of its effort
to modernize its weaponry. The army wants them for combating terrorism, transnational crime, and insurgency
to secure thearchipelago.[68]
Variants[edit]
The UH-60 comes in many variants, and many different modifications. The U.S. Army variants can be fitted
with the stub wings to carry additional fuel tanks or weapons.[11] Variants may have different capabilities and
their respective equipment in order to fulfill different roles.
