USCG HH-65A Dolphin Helicopter

These are aircrew members who are participating in water survival training as part of aircrew certification in Long Beach Island, N.J., but this would indeed be a welcome sight to anyone experiencing problems offshore.

The HH-65A is used to perform search and rescue; enforcement of laws and treaties (including drug interdiction), polar ice-breaking, marine environmental protection including pollution control, and military readiness missions. Though normally stationed ashore, the HH-65A can land and take-off from 210-foot WMEC, 270-foot WMEC, and 378-foot WHEC Coast Guard Cutters. These cutters are capable of refueling and supporting the helicopter for the duration of a cutter patrol.

The HH-65A minimum equipment requirements exceed anything previously packaged into one helicopter weighing in at less than 10,000 pounds. HH-65As are made of corrosion-resistant, composite-structure materials. The shrouded tail rotor is unique to the Dolphin. Also a unique feature of the Dolphin is its computerized flight management system which integrates state-of-the-art communications and navigation equipment. This system provides automatic flight control. At the pilot's direction, the system will bring the aircraft to a stable hover 50 feet above a selected object. This is an important safety feature in darkness or inclement weather. Selected search patterns can be flown automatically, freeing the pilot and copilot to concentrate on sighting the search object.

The Dolphin is manufactured by Aerospatiale Helicopter Corporation in Grand Praire, Texas. Textron Lycoming builds the LTS-101 750B-2 turboshaft engines in Williamport, Pennsylvania and Rockwell International, Collins Avionics Group manufactures the electronics system in Cedar Rapids, Iowa.

The HH-65A planned service life would end in 2006. An SRR mission analysis began in 2000. IOC would follow in 2004, with the project complete in 2008. A Service Life Extension Program (SLEP), including updated avionics, increased payload, and increased power from the LTS-101 engines, was evaluated for the HH-65A. If implemented, the SLEP will extend Coast Guard HH-65 operations through 2015. Efforts are already underway to upgrade the HH-65A fleet by adding an NVG compatible cockpit, TCAS, GPS, an upgraded Environmental Control System utilizing R-134, a refrigerant, and an upgraded main gear box to increase payload.

The Dolphin is primarily a Short Range Recovery (SRR) aircraft. There are total of 96 Dolphins in the Coast Guard Fleet. The Dolphin replaced the old HH-52A Sea Guard helicopter. The fleet has home ports in 17 cities on the Atlantic and Pacific Oceans, Hawaii, and the Great Lakes region.

The Dolphin is a twin engine helicopter powered by, two Lycoming LTS-101-750B-2 each producing 742 shaft HP. The Dolphin is usually deployed from shore but it can be deployed from medium and high endurance Coast Guard Cutters, as well as the Polar Icebreakers. The Dolphin's main jobs are: search and rescue, enforcement of laws and treaties (including drug interdiction), polar ice breaking, marine environmental protection including pollution control, and military readiness.

When deployed from an icebreaker, the helicopter acts as the ship's eyes, searching out thinner and more navigable ice channels. They also have the job of airlifting supplies to villages isolated by winter, or transporting scientists to conduct remote research.

The minimum equipment requirements exceed anything previously put into one helicopter under 10,000 pounds. The material used to make the helicopter is corrosion-resistant, composite-structure materials. The shrouded tail rotor is also unique to the Dolphin. Another powerful tool that the Dolphin wields is its state-of-the-art communication and navigation equipment. This system provides automatic flight control. At the pilot's direction, the system will bring the aircraft to a stable hover 50 feet above a selected object.
