The Eurocopter HH-65 Dolphin is a twin-engine, single main rotor,
MEDEVAC-capable search and rescue (SAR) helicopter operated by the United States
Coast Guard (USCG). It is a variant of the French-built Eurocopter AS365
Dauphin.
The SA366 G1 Dauphin version was selected by the United States Coast Guard in
1979 as its new short range recovery (SRR) air-sea rescue helicopter, replacing
the Sikorsky HH-52A Sea Guard. In total 99 helicopters, optimised for the USCG's
search and rescue role tasks and given the designation HH-65A Dolphin, were
acquired. Unlike the HH-52, the HH-65A is not able to perform water landings.
The HH-65 normally carries a crew of four: Pilot, Copilot, Flight Mechanic and
Rescue Swimmer.
The HH-65A's minimum equipment requirements exceeded anything previously
packaged into a helicopter weighing less than 10,000 pounds (4,535 kg).
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 (15 m)
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 & searching the object.

The Dolphin is primarily a Short Range Recovery (SRR) aircraft. There are now a
total of 102 Dolphins in the Coast Guard Fleet. The fleet has home ports in 17
cities on the Atlantic and Pacific Ocean, Gulf of Mexico, Hawaii, and the Great
Lakes region.
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.
