Sikorsky UH-60 Black Hawk
The Black Hawk helicopter is the workhorse of many-an-army on todays battlefield.
By Staff Writer
The Sikorsky UH-60 Black Hawk has become a workhorse for the United States and other military forces the world over. Its capabilities have increased her roles to include Special Operations assignments, assault, MedEvac, Command and Control and VIP transport duty on top of her inherent troop-transport capabilities. The first production Black Hawk entered service in 1979 and remains a primary fixture for many an army even today - two decades after its inception. Some 2,600 total Black Hawks have been delivered worldwide.
The Black Hawk was born out of the Sikorsky S-70 project designed to the United States Army's Utility Tactical Transport Aircraft System (UTTAS) specification that began in the latter part of the 1960's. The specification itself originated on the data collected from wartime use of the UH-1 "Huey" Iroquois helicopters pulling multiple duties across the war zone. Review of this experience brought about a need for capable replacement system for the immediate future. This design specification also coincided with development of the new General Electric turboshaft engine series designated as the T700. US Army feelers went out in 1972 with both Sikorsky and Boeing-Vertol both answering the call. The Sikorsky design was chosen ahead of the Boeing-Vertol YUH-61A attempt and the Sikorsky YUH-60A prototype achieved first flight on November 29th, 1974. The production contract was handed to Sikorsky in late 1976 with first deliveries of the Black Hawk system beginning on an October day two years later. The Black Hawk was officially introduced into service in the middle of 1979 with the US Army 101st Airborne Division, replacing the venerable UH-1 Hueys.
Black Hawks have a distinct look about them making them highly recognizable even when compared to her contemporaries. The forward portion of the fuselage contains seating positions for the pilot and co-pilot (collectively known as the flight crew) with windowed panels above, forward-below and to the sides. Each crew position is afforded an entry-exit door. Directly behind the cockpit is the cabin that allows for seating of some 11 personnel (depending on the version) with entry/exit made by two double-windowed sliding doors. The General Electric series turboshaft engines sit atop either side of the middle-fuselage with the four-blade main rotor extending up between them. The empennage is of conventional design and layout, featuring a four-blade tail rotor positioned to the starboard side, single vertical fin structure and horizontal plane. The undercarriage is fixed and features to main landing gears forward (complete with wire cutters ahead of each component) and a single tail wheel fitted under the fuselage area between the cabin and extreme edge of the tail.
Performance from the twin turboshaft engines provide for a top approximate speed of 183 miles per hour with a "never exceed" speed of up to 222 miles per hour. Cruise speeds are typically 173 miles per hour. A combat radius of 368 miles is possible with a ferry range of 1,380 miles. The service ceiling is reported at 19,000 feet with a 700 feet-per-minute rate-of-climb. Cargo hauling capacity is 2,640lbs of freight held internally. An 8,000lb freight limit is imposed for external hauling.
As expected, the Black Hawk helicopter can accomplish just about any battlefield-related task it is assigned. This includes its standard role as a troop-carrying implement but can also be expanded to include cargo/artillery transport, offensive assault, Special Operations insertion/extraction along with Search & Rescue and MedEvac. Several Black Hawks have been modified for VIP transport roles for the US government and take on the call sign of "Marine One" when specifically transporting the President of the United States.
Variants range from utility based to specialty models. The original US Army production Balck Hawk became the UH-60A while the UH-60L appeared with upgraded T700-GE-701C engines and other updates. The UH-60M appeared with further improvements and replaced original production Black Hawks. MedEvac versions included the UH-60Q while Special Operations Forces were given the specialized and armed MH-60K and MH-60L models. VIP models in US service were the VH-60D "Nighthawk" and VH-60N "Whitehawk" variants.
Sikorsky S-70 is the company designation for the series. UH-60 "Black Hawk" is generally the US Army designation while HH-60 "Pave Hawk" is the United States Air Force designation. The US Coast Guard uses the helicopter in its specially developed HH-60 "Jayhawk" guise. The United States Navy operates the SH-60 "Seahawk". Many export versions of the Black Hawk have surfaced as well with most under the base S-70 designation (see variants list for complete details).
When armed, the Black Hawk can take on firepower in the form of 30mm chain guns, machine gun pods, heavy caliber and general purpose machine guns and miniguns. Additionally, optional wing stubs can provide for the use of external fuel tanks (coming in two sizes - see armaments suite for specifics) for increased operational ranges or Hellfire anti-tank missiles and 2.75" rocket pods for increased lethality.
The UH-60 Black Hawk made its US combat debut in the 1983 Invasion of Grenada and later in the 1989 Invasion of Panama. The Black Hawk was put to good use in the 1991 coalition offensive of the 1991 Persian Gulf War to remove Saddam Hussein's invasion force from Kuwaiti soil. Perhaps the Black Hawks involvement in the assault on the capital city of Mogadishi in Somalia is what most observers will forever remember in regards to the helicopter's history. In the assault, two Black Hawk helicopters were shot down by enemy rocket-propelled grenades, leading to the horrifically televised display of the loss of American lives (18 in all, including one captured and 73 wounded), effectively signaling the beginning of the end of US involvement in that country. At the turn of the century, 9/11 forced direct American involvement in Afghanistan and - later - Iraq, extending the, yet, unwritten history of the Black Hawk helicopter into tomorrow.
The UH-60M represents the current Black Hawk production model. Operators of the Black Hawk range from the Pacific Rim to South America, the Middle East to Europe. Some of the largest operators include the United States, Columbia, South Korea, Turkey and Australia.
The UH-60 Black Hawk, in all its varied forms, should continue to see active service at least through 2020.
