Aerospatiale SA 366/HH-65A Dolphin

In 1979, the U.S. Coast Guard began looking for a new helicopter for the short-range recovery (SSR) role. Eurocopter's SA 366G was selected, beating out the Bell 222 and Sikorsky S-76. Over the next five years, 96 helicopters were acquired by the USCG, which designated the helicopter the HH-65A Dolphin. Although the helicopter is usually operated from land bases, it is also capable of shipboard operations as well. It features a 3,500-lb. hoist for sea rescues, and is also used for drug trafficking operations.

The helicopter has a crew of three: a pilot and copilot who sit in tandem, and a flight engineer. The baggage area can be fitted with a 47.5-gallon auxiliary tank for increased range, plus an additional 125-gallon tank in place of passenger seating. The Dolphin burns 61 gallons of jet fuel per hour of routine usage. It has a range of 472 miles with maximum fuel or 248 miles with maximum passenger load; typical endurance is 4 hours. A full tank of fuel costs $900.
