Sikorsky S-70 H-60 Hawk family
The UTTAS competition was born October 1965, when a Qualitative Material Development Objective was approved by the US Department of Defence (DoD). The specification called for an aircraft able to carry a crew of three and eleven troops, a 3150 kg slung load, at a cruising speed of 270/320 km/h. Requests for proposals were issued to the US industry on 5 January, 1972. Bell, Boeing Vertol and Sikorsky submitted five proposals and the last two were selected to proceed to prototype construction with contracts being placed on 30 August, 1972. The Sikorsky S-70 was declared winner on Dec. 26,1976
Configured in more than 10 different versions for the US armed forces, had became more popular since 1978 when the first unit was given to the US Army and 2000 Hawks were already built by 1994.
The latest UH-60M variant represents the US army's third standard baseline Blackhawk version in the history of the program. Sikorsky delivered the UH-60A from 1978 until 1989 and has been delivering the UH-60L since 1989. As of 2006, is nearing the end of production of that variant for the US army as it transitions to the UH-60M.
As an example of this helicopter effectiveness, on December 2000 a dramatic rescue took place 200 miles (322 kilometres) off the coast of Virginia, USA. The cruise liner SeaBreaze I suffered an engine failure during a storm and soon began taking on water. One US Coast Guard HH-60J Jayhawk helicopter rescued 26 crewmembers and another Jayhawk rescued the remaining eight. The helicopter with the 26 rescued sailors aboard, combined with its own four crewmen, set a new record for the most people aboard a single H-60.
US Navy SeahawksThe Seahawks for the US Navy come in three versions, SH-60B, SH-60F,and HH-60H.
The SH-60B was the first of the bunch and can be distinquished by its surface search radar underneath the cockpit, between the wheels. Also all SH60B's have a sonobouy launcher on the left side that looks like a five by five set of tubes. SH60Bs are used off cruisers and destroyers for antisubmarine warfare and surface search and surveillance.
The SH-60F is the next in line and is the carrier based version of the Seahawk. It has a dipping sonar (unique in the Seahawk family), it is used to find submarines. It is also the "slickest" of the group having very little things sticking out of it. It has no surface search radar or side mounted sonobouy launcher. It is most often confused with the B model, not the H.
The HH-60H is the final version. It has the two sliding windows on the left side. It also has the speacial HRSS nozzels on the exhaust to reduce heat signature. Some times, the HH-60H can be seen with a nose mounted FLIR ball and HELLFIRE missiles. It is used for Cargo, Combat Search and Rescue, and other missions.
Currently the US Navy is buying the MH-60R and MH-60S (previously known as SH-60R and CH-60S Knighthawk ) which will eventually replace the three models.
US Air Force HH/MH-60G PavehawksThe Air Force variants were the first Hawks to introduce an air-refueling capability. There is (was) virtually no difference between the MH-60G Pave Hawk and the HH-60G Pave Hawk with a few minor exceptions. The biggest difference (and determining factor in the designation) is the command that they were assigned to. The 10 MH-60G's were assigned to AF Special Operations Command (AFSOC) and hence the "MH" designation for "multi mission". The MH-60G's also had a different paint scheme -- a dark gray similar to the other AFSOC aircraft like the MH-53J/L Pave Low and the MC-130's. The remaining HH-60G's were assigned to rescue duties with Air Combat Command (ACC) and painted woodland camouflage. The other minor differences are that the MH-60G's had "Sea Hawk" windows long before the HH-60G's, the (former) MH-60G's all have rotor brakes, and they have windshield washer reservoirs and motors. When the USAF had both designations in service, there was only one Operator's Manual ("Dash 1") and it was for the "MH/HH-60G Pave Hawk". With the closing of the only AFSOC MH-60G unit in the late 90's, the MH-60G's were transferred to ACC, painted woodland camo, and redesignated HH-60Gs. The USAF currently has no MH-60G Pave Hawks in service -- they are all now HH-60G Pave Hawks... though that may change with the move of ALL HH-60G's to AFSOC on October 2003.
