The Eurocopter HH-65 Dolphin is a twin-engined, 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 Dolphin was manufactured by Aerospatiale Helicopter Corporation (now American Eurocopter) in Grand Prairie, Texas. HH-65 Dolphin (Wallpaper 1).

Textron Lycoming (now Honeywell) built the Dolphin's LTS101-750B-2 turboshaft engines in Williamsport, Pennsylvania, and Rockwell Collins manufactured the HH-65's electronic systems in Cedar Rapids, Iowa. The HH-65 Dolphin is used for homeland security patrols, cargo, drug interdiction, ice breaking, military readiness, pollution control, and search and rescue missions. The HH-65 is known for its Fenestron tail rotor and its autopilot capabilities, which can complete an unaided approach to the water and bring the aircraft into a stable 50 ft (15 m) hover, or automatically fly search patterns, an ability which allows the crew to engage in other tasks. In order to comply with U.S. regulations relating to local content (based primarily on the value of individual components of the aircraft), engineering changes were required — notably, the SA365's original Turbomeca Arriel engines were replaced with LTS101-750B-2 powerplants, which at the time represented the cutting edge of turboshaft design. Unfortunately, initial teething problems with this engine worsened as the HH-65's weight grew, resulting in several in-flight loss-of-power events. The USCG funded a program to improve engine reliability, but the resulting LTS101-850 failed to meet expectations. HH-65 Dolphin (Wallpaper 1).
