Turbomeca has produced over 2,000 Arrius turboshaft engines to date, logging more than 2,800,000 flight hours with 430 customers in 60 countries.

The Arrius family was launched in 1981. Today, it powers the newest generation single and twin-engine light helicopters. There are four basic variants in Turbomeca's Arrius family: Arrius 1A/1M, Arrius 2F, Arrius 2B1/2B2 and Arrius 2K1/2K2. Takeoff power ranges from 357 kW (479 shaft horsepower) to 530 kW (716 shp).

The Arrius 1 powers the twin-engine Eurocopter AS355 N Ecureuil and its military version, the AS555 N Fennec.

The Arrius 2F powers the single-engine Eurocopter EC 120 B.

The Arrius 2B2, the latest version of the Arrius family, entered service mid-2002 and powers the light twin-engine, Eurocopter EC135.

The Arrius 2K1 was FAA-certified in late 2001. It powers the Agusta A109E Power. It has entered service in the USA and in Europe for medevac missions.

The Arrius 2K2 powers the twin-engine Agusta A 109 LUH (Light Utility Helicopter) ordered by South Africa Air Force (SAAF), Malaisia and Sweden. The A 109 LUH performs in medevac, surveillance, rescue and troop-carrier military roles.

The Arrius 2G2 will power the Kamov 226. A MOU (Memorandum of Understanding) was signed in April 2002 with the Russian engine manufacturer Kamov to power the Kamov-226. The helicopter is designed for the Russian and export markets.
