The Sikorsky HH-60 Jayhawk is a twin-engine medium-range search and rescue (SAR) helicopter. It is based on the SH-60 Seahawk, which is a navalized variant of the US Army's UH-60 Black Hawk utility helicopter. Besides SAR, the HH-60 is used for drug interdiction, cargo lift, and special operations. It was developed for the United States Coast Guard to replace the aging Sikorsky Aircraft HH-3F Pelican in 1986.

Design and development

The HH-60J Jayhawk development began in 1986 based on the HH-60H Rescue Hawk airframe. The Jayhawks were delivered to the US Coast Guard in the early 1990s. The HH-60J has a radar for search/weather that gives its nose a distinctive look. A forward-looking infared (FLIR) sensor turret can be mounted below its nose. It can carry three convert|120|USgal|l|sigfig=3|abbr=on|lk=on fuel tanks with two on the port side rack and one on the starboard side rack. The starboard also carries a rescue hoist with a convert|600|lbf|kN|sigfig=3|abbr=on|lk=on capability mounted above the door. [Leoni 2007, pp. 212-214.] The hoist has convert|200|ft|m|sigfig=3|abbr=on|lk=off of cable.

The Jayhawk has a convert|6460|lb|kg|sigfig=3|abbr=on|lk=off fuel capacity allows it to operate for 6.5 hours within a convert|300|nmi|km|sigfig=3|abbr=on|lk=on radius. [http://www.uscg.mil/acquisition/mrr/features.asp Medium Range Recovery Helicopter features] , US Coast Guard, December 13, 2007.] The helicopter is not able to perform water landings as was its amphibious HH-3F Pelican predecessor. [http://www.uscg.mil/datasheet/hh-60.asp HH-60 "Jayhawk" Medium Range Recovery Helicopter] , US Coast Guard, February 5, 2008.]

A total of 42 Jayhawks were built by Sikorsky Aircraft Corporation with 35 in operation and another 7 in storage or support roles.

The HH-60Js began an upgrade program to convert them to medium range responder helicopters in January 2007, and will be redesignated as MH-60T. The program, called Deepwater Program will provide a glass cockpit and other upgrades. [http://www.uscg.mil/acquisition/deepwater/newsletters/jan07/newsletter_jan07-04.asp Aviation Update newsletter] , US Coast Guard, January/February 2007.] The MH-60T is modified with an airborne use of force package, including weapons for firing warning and disabling shots, and armor to protect the aircrew from small arms fire.
