Sikorsky HH-60 Jayhawk
The Sikorsky HH-60J Jayhawk is a multi-mission, twin-engine, medium-range helicopter operated by the United States Coast Guard for search and rescue, law enforcement, military readiness and marine environmental protection missions. The HH-60J is designed to fly a crew of four up to 300 mi (483 km) offshore, hoist up to 6 additional people on board while remaining on-scene for up to 45 minutes and return to base while maintaining an adequate fuel reserve. Normal cruising speed of the HH-60J is 135 to 140 kn (155 to 161 mph) and the aircraft is capable of reaching 180 kn (207 mph) for short durations. The HH60J can fly at 140 kn (161 mph) for six to seven hours.
Chosen to replace the HH-3F Pelican, the HH-60J is a member of the Sikorsky S-70 family of helicopters and is based on the United States Navy's SH-60 Seahawk helicopter. Development began in September 1986, first flight was achieved on August 8, 1989, and the first HH-60J entered USCG service in June 1990. Production ended in 1996 after 42 helicopters were produced.
The MH-60T Medium Range Recovery Helicopter upgrade program began in 2007 and is scheduled to provide upgraded avionics and operational capabilities to all 42 existing HH-60J airframes by 2015. As each airframe upgrade is completed, the affected HH-60J will be re-designated to MH-60T.
