UH-60 Black Hawk



The Black Hawk is the Army旧 front-line utility helicopter used for air assault, air cavalry, and aeromedical evacuation units. It is designed to carry 11 combat-loaded, air assault troops, and it is capable of moving a 105-millimeter howitzer and 30 rounds of ammunition. First deployed in 1978, the Black Hawk旧 advanced technology makes it easy to maintain in the field. The Black Hawk has performed admirably in a variety of missions, including air assault, air cavalry and aeromedical evacuations. In addition, modified Black Hawks operate as command and control, electronic warfare, and special operations platforms.


The UH-60A, first flown in October 1974, was developed as result of the Utility Tactical Transport Aircraft System (UTTAS) program. The UTTAS was designed for troop transport, command and control, MedEvac, and reconnaissance, to replace the UH-1 Series "Huey" in the combat assault role. In August 1972, the U.S. Army selected the Sikorsky (model S-70) YUH-60A and the Boeing Vertol (model 237) YUH-61A (1974) as competitors in the Utility Tactical Transport Aircraft System (UTTAS) program. The Boeing Vertol YUH-61A had a four-bladed composite rotor, was powered by the same General Electric T700 engine as the Sikorsky YUH-60A, and could carry 11 troops. In December 1976 Sikorsky won the competition to produce the UH-60A, subsequently named the Black Hawk.
The Black Hawk is the primary division-level transport helicopter, providing dramatic improvements in troop capacity and cargo lift capability compared to the UH-1 Series "Huey" it replaces. The UH-60A, with a crew of three, can lift an entire 11-man fully-equipped infantry squad in most weather conditions. It can be configured to carry four litters, by removing eight troop seats, in the MedEval role. Both the pilot and co-pilot are provided with armor-protective seats. Protective armor on the Black Hawk can withstand hits from 23mm shells. The Black Hawk has a cargo hook for external lift missions. The Black Hawk has provisions for door mounting of two M60D 7.62mm machine guns on the M144 armament subsystem, and can disperse chaff and infrared jamming flares using the M130 general purpose dispenser. The Black Hawk has a composite titanium and fiberglass four-bladed main rotor, is powered by two General Electric T700-GE-700 1622 shp turboshaft engines, and has a speed of 163 mph (142 knots).


Elements of the US Army Aviation UH-60A/l Blackhawk helicopter fleet will begin reaching their sevice life goal of 25 years in 2002. In order for the fleet to remain operationally effective through the time period 2025-2030 the aircraft will need to go through an inspection, refurbishment, and modernization process that will validate the structural integrity of the airframe, incorporate improvements in sub-systems so as to reduce maintenance requirements, and modernize the mission equipment and avionics to the levels compatible with Force XXI and Army After Next (AAN) demands.

A Service Life Extension Program (SLEP) is planned for the UH-60 beginning in FY99. The UH-60 modernization program will identify material requirements to effectively address known operational deficiencies to ensure the Black Hawk is equipped and capable of meeting battlefield requirements through the 2025-2030 timeframe. Primary modernization areas for consideration are: increased lift, advanced avionics (digital communications and navigation suites), enhanced aircraft survivability equipment (ASE), increased reliability and maintainability (R & M), airframe service life extension (SLEP), and reduced operations and support (O & S) costs. Suspense date for the approved Operational Requirements Document (ORD) is December 1998.

Variants
The Army began fielding the UH-60 in 1978. From 1978 until 1989 the Army procured UH-60A model aircraft. In October 1989, a power train upgrade resulted in a model designation change from UH-60A to UH-60L. The UH-60L version that provides 24 percent more power than the original 1970 UH-60A model. As of the end of FY97, the Army had procured 483 UH-60L models for a total UH-60 acquisition of 1,463 aircraft. The Army is in the fifth and final year of a multi-year procurement contract calling for the delivery of 60 aircraft per year.

UH-60L
In October 1989, the engines were upgraded to two General Electric T700-GE-701C 1890 shp turboshaft engines, and an improved durability gear box was added, resulting in a model designation change from UH-60A to UH-60L. The T700-GE-701C has better high altitude and hot weather performance, greater lifting capacity, and improved corrosion protection. The helicopter can carry a gross weight of 22,000 Lbs and an external load of 9,000 Lbs. The UH-60L variant can utilize an External Stores Support System or ESSS to expand its capabilities. The ESSS system consists of removable "four-station pylons" that can carry external fuel tanks that can extend the Blackhawk range up to 1,150 nautical miles or sixteen Hellfire missiles. Furthermore, Sikorsky states that the Blackhawk can store an additional sixteen Hellfire missiles internally, and deploy a wide range of weapons systmes ranging from guns to mine dispensers.

MH-60G Pave Hawk
The Pave Hawk is a twin-engine medium-lift helicopter operated by the Air Force Special Operations Command, a component of the U.S. Special Operations Command. The MH-60G's primary wartime missions are infiltration, exfiltration and resupply of special operations forces in day, night or marginal weather conditions. Other missions include combat search and rescue. During Desert Storm, Pave Hawks provided combat recovery for coalition air forces in Iraq, Saudi Arabia, Kuwait and the Persian Gulf. They also provided emergency evacuation coverage for U.S. Navy sea, air and land (SEAL) teams penetrating the Kuwait coas t before the invasion.

The MH-60G is equipped with an all-weather radar which enables the crew to avoid inclement weather. To extend their range, Pave Hawks are equipped with a retractable in-flight refueling probe and internal auxiliary fuel tanks. Pave Hawks are equipped with a rescue hoist with a 200-foot (60.7 meters) cable and 600-pound (270 kilograms) lift capacity. All MH-60G's have an automatic flight control system to stabilize the aircraft in typical flight altitudes. They also have instrumentation and engine and rotor blade anti-ice systems for all-weather operation. The non-retractable landing gear consists of two main landing gears and a tail wheel. Aft sliding doors on each side of the troop and cargo compartment allow rapid loading and unloading. External loads can be carried on an 8,000-pound (3,600 kilograms) capacity cargo hook. Pave Hawks are equipped with folding rotor blades and a tail stabilator for shipboard operations and to ease air transportability.

MH-60K is the standard special operations version of the Black Hawk. It is capable of providing long-range airlifts far into hostile territory in adverse weather conditions. Modifications include two removable 230 gallon external fuel tanks, two .50 cal. machine guns, an air-to-air refueling probe, and an external hoist. The MH-60K can also be armed with two M134 7.62mm "miniguns". A new avionics suite includes interactive Multi-Function Displays (MFDs), Forward-Looking Infrared (FLIR), digital map generator, and terrain avoidance/terrain following multi-mode radar. Survivability equipment includes radar and missile warning systems and IR jammers. The MH-60K has full shipboard operability. It is powered by two General Electric T700-GE-701C 1843 shp turboshaft engines.

The older MH-60L can be adapted to the attack mission by attaching dual weapons pylons to both sides of the fuselage. Pylon mounting cannon, rockets, or missiles can be supplemented by door or port mounting guns or launchers, limited mainly by the range, duration, cargo, or troops required to complete the mission. The helicopter's mission is insertion and extraction of special operations troops. Survivability equipment includes radar and missile warning systems and IR jammers. The MH-60L is powered by two General Electric T700-GE-701C 1843 shp turboshaft engines.

HH-60G Pave Hawk

The HH-60G's primary wartime mission is combat search and rescue, infiltration, exfiltration and resupply of special operations forces in day, night or marginal weather conditions. The HH-60G Pave Hawk provides the capability of independent rescue operations in combat areas up to and including medium-threat environments. Recoveries are made by landing or by alternate means, such as rope ladder or hoist. Low-level tactical flight profiles are used to avoid threats. Night Vision Goggle (NVG) and Forward Looking Infrared (FLIR) assisted low-level night operations and night water operation missions are performed by specially trained crews. The basic crew normally consists of five: pilot, co-pilot, flight engineer, and two PJs. The aircraft can also carry eight to 10 troops.
Pave Hawks are equipped with a rescue hoist with a 200-foot (60.7 meters) cable and 600-pound (270 kilograms) lift capacity. The helicopter hoist can recover survivors from a hover height of 200 feet above the ground or vertical landings can be accomplished into unprepared areas. The hoist can recover a Stokes litter patient or three people simultaneously on a forest penetrator.

The helicopter has limited self-protection provided by side window mounted M-60, M-240, or GAU-2B machine guns. Pave Hawk is equipped with two crew-served 7.62mm miniguns mounted in the cabin windows. Also, two .50 caliber machine guns can be mounted in the cabin doors. An APR-39A(V)1 radar warning receiver, ALQ-144A infrared jammer, Hover Infrared Suppression System (HIRSS), M-130 chaff dispenser, and precision navigation equipment (GPS, Inertial Navigation System (INS), Doppler) afford additional threat avoidance and protection.

Mission systems on the HH-60H make it ideally suited for operations with special warfare units. Combat-equipped personnel can be covertly inserted and/or extracted in any terrain with precise GPS navigation accuracy. A variety of insertion and extraction techniques are available, including landing, hoisting, fastrope, rappel, paradrop, McGuire or SPIE Rig, and CRRC. Additionally, Helicopter Visit Board Search and Seizure (HVBSS) operations may be conducted using one or more of these insertion/extraction techniques. HVBSS missions are designed to take control of a ship considered to be a Contact of Interest (COI). The ability to interdict or 'take down' shipping during enforcement of a naval blockade requires precise planning and execution. Tethered Duck (T-Duck) was implemented to rapidly insert troops and a Combat Rubber Raiding Craft (CRRC) to water areas. The troops fastrope down to the CRRC after it is lowered into the water, and the motor is then hoisted down to the troops to complete the procedure. Parachute operations are used for inserting troops when the helicopters are unable to land with a minumum free-fall drop altitude of 2500 feet AGL (above ground level).


The maximum speed is 193 knots with a cruise speed of 120 to 140 knots. Unrefueled range is 480 nautical miles (NM), with a combat load and aircraft at maximum gross weight of 22,000 lbs; the combat radius is approximately 200NM. Inflight refueling greatly extends this range. Pave Hawks are equipped with a retractable in-flight refueling probe and internal auxiliary fuel tanks.
All HH-60G's have an automatic flight control system to stabilize the aircraft in typical flight altitudes. They also have instrumentation and engine and rotor blade anti-ice systems for all-weather operation. The HH-60G is equipped with an all-weather radar which enables the crew to avoid inclement weather. Pave Hawks are equipped with folding rotor blades and a tail stabilator for shipboard operations and to ease air transportability. The non-retractable landing gear consists of two main landing gears and a tail wheel. Aft sliding doors on each side of the troop and cargo compartment allow rapid loading and unloading. External loads can be carried on an 8,000-pound (3,600 kilograms) capacity cargo hook. The Pave Hawk can be equipped with the external stores support system.

The HH-60 is stationed throughout the world. MAJCOMS include AFRC, ANG, AFSOC, PACAF, AFMC, AETC, and ACC. ACC is the lead command. Besides a full complement of flightline support, home stations provide two and three level maintenance support functions. HH-60 helicopter is a worldwide deployable aircraft. Two 365 day a year contingencies are currently being conducted. In deployment scenarios some locations have full flightline support capabilities with limited backshop support, while other deployed sites have less support, down to a bare base scenario. A flightline support contingent is deployed with the aircraft. Depending on the deployment location and duration, varying levels of backshop maintenance support might also be deployed.


HH-60G is rapidly approaching its flying hour service life limit. Consequently, CAF will soon require either a service life extension program (SLEP) for HH-60G or procurement of a replacement aircraft for conducting CSAR operations. The HH-60G System Program Office (WR-ALC/LU) is assessing whether HH-60G旧 service life limit is 8,000 flight hours, IAW the Army specification for the H-60 airframe, or actually closer to 7,000 flight hours based upon AF configuration and operating gross weights of the HH-60G. Depending on the assessment results, HH-60G aircraft (1981 models) will begin reaching their service life limit as early as FY00, if service life limit is determined to be 7,000 flight hours. Otherwise, if the limit is determined to be 8,000 flight hours, 1981 model HH-60G aircraft will begin reaching their service life limit in FY03.

Air Combat Command (ACC) is analyzing concepts/alternatives to assess their relative cost effectiveness and affordability for sustaining the U.S. Air Force's Combat Search and Rescue (CSAR) capability. After complete concepts/alternatives (aircraft platform- level,including subsystems, and support/training systems) are received, the Air Force intends to analyze those that provide the most opportunity to satisfy currently deficient mission capabilities while maintaining, as a minimum, existent Combat Rescue capability. A detailed Analysis of Alternatives (AoA) will follow to ascertain whether or not the concepts/alternatives exceed/meet/do not meet the specific measures of effectiveness. The AoA will include modeling, simulation, and CSAR scenarios projected for 2010. If this analysis results in the initiation of an acquisition program to procure a replacement for the HH-60G aircraft, the Initial Operational Capability (IOC) would be in place by the end of FY07.
