EC155

The EC155 is a twin‑engine civil helicopter developed by Aérospatiale and later marketed by Eurocopter (now Airbus Helicopters). It is part of the Dauphin/Super Puma family and was designed to provide a larger cabin and improved performance for passenger transport, offshore operations, EMS, and VIP missions. The EC155 first flew in the late 1990s and entered service in the early 2000s. It is commonly configured to carry up to about 12 passengers plus two crew, depending on the mission profile.

Design and features include a five‑blade main rotor and a Fenestron tail rotor, which help reduce noise and improve safety. Power is provided by two Turbomeca Makila engines. The cabin is known for its wide interior and configurable layout, enabling crew and passenger comfort as well as quickly reconfigurable spaces for medical or VIP use. Avionics typically include a glass cockpit with modern flight management systems, and many aircraft can be equipped with weather radar, night vision compatibility, and other mission equipment for all‑weather operations.

Variants of the EC155 include the original EC155 B1 and the later EC155 B2, which offered uprated engines and upgraded avionics. In 2015, Airbus Helicopters began marketing the aircraft under the name H155. The EC155 family has been widely used for offshore oil and gas transport, as well as for VIP transport, search and rescue, and emergency medical services, reflecting its versatility across multiple mission profiles.

Overall, the EC155 represents a mid‑size, multi‑purpose helicopter that bridged older Dauphin designs with modern avionics and comfort, continuing to serve in various roles within the broader Airbus helicopter lineup.
