General Characteristics
The MH-65 Dolphin is the primary Short Range Recovery (SRR) helicopter for the United States Coast Guard (USCG). It is an Americanized variant of the French-built Eurocopter AS365 Dauphin. The MH-65 is known for its distinctive Fenestron tail rotor and its advanced digital flight management system, which provides unique safety and auto-hover capabilities essential for search and rescue (SAR) missions.

Design and Powerplant
- Engines: Two Turbomeca Arriel 2C2-CG turboshaft engines. (Original HH-65A used Lycoming LTS101 engines).
- Power Output: Approximately 636 kW (853 shp) per engine. The engine upgrade provides 40% more power than the original configuration.
- Tail Rotor: Features the Fenestron (shrouded tail rotor), which is safer for ground crews and produces less noise than a conventional tail rotor.
- Autopilot: Equipped with a sophisticated digital autopilot that can automatically fly pre-programmed search patterns and bring the aircraft to a stable 15 m (50 ft) hover above a selected object (an important safety feature for hoisting).
- Construction: Airframe, rotor head, and rotor blades are made of corrosion-resistant composite materials, suitable for the harsh maritime environment.
Performance and Mission Capabilities
- Max Cruise Speed: 274 km/h (170 mph, 148 knots).
- Maximum Range: Approximately 650 km (350 nautical miles).
- Endurance: Around 3 hours.
- Service Ceiling: 5,486 m (18,000 ft).
- Armament (MH-65C/D/E): Equipped for Airborne Use of Force (AUF) missions, including mounting a 7.62 mm M240B/H machine gun and a .50-caliber precision rifle for disabling non-compliant vessels.
- Mission Profile: Primarily a Short Range Recovery (SRR) aircraft, performing SAR, counter-narcotics, homeland security patrols, and operating from medium/high endurance Coast Guard Cutters.
- Latest Variant (MH-65E): Features a complete digital glass cockpit (Common Avionics Architecture System – CAAS) and advanced navigation capabilities, extending the service life to the 2030s.
