The HH-60 Jayhawk is a twin-engine medium-range search and rescue (SAR) helicopter, based on the airframe of the SH-60 Seahawk. Besides SAR, it is used for drug interdiction, cargo lift, and special operations. It was developed for the United States Coast Guard to replace the aging Sikorsky HH-3F Pelican in 1986.

Development

The Jayhawk is manufactured by Sikorsky Aircraft Corporation, 42 were built with 35 in operation and another 7 in storage or support roles. The 6,460 lb (2930 kg) fuel capacity allows the Jayhawk to operate for 6:30 hours within a 300 nautical mile radius. The rescue hoist can handle 600 lb (272 kg), but the helicopter is not able to perform water landings as its predcessor the Pelican was.
