Royal Thai Army H125M/AS550 C3 Fennec Light Attack Helicopter

The Eurocopter (now Airbus Helicopters) AS550 Fennec and AS555 Fennec 2 are lightweight, multipurpose military helicopters manufactured by Eurocopter Group (now Airbus Helicopters). Based on the AS350 Ecureuil and AS355 Ecureuil 2 series, they are named after the Fennec Fox. The armed versions of the AS550 and AS555 can be fitted with coaxial weapons, rockets, torpedoes and various other munitions.

Airbus’ two-tonne H125M (formerly the AS550 C3e Fennec) responds to military requirements for a cost-effective armed platform with a very small footprint and excellent manoeuvrability.

The H125M is tailored for locating and attacking targets of opportunity. It relies on the qualities of power, simplicity, firing stability and stealth to carry out a diverse range of demanding missions.

The H125M can be equipped with Airbus’ HForce weapons system – a comprehensive, modular and cost-efficient weapon system that can be used on any military version of Airbus’ civil helicopter range (H125M, H145M and H225M).

Able to fly discreetly in the battlefield with a small silhouette, the H125M has a reduced radar signature through the use of composite materials and infrared-reflective paint.

This helicopter benefits from the excellent handling characteristics and easy-to-fly qualities that are inherent in Airbus’ single-engine Ecureuil family – which holds the world altitude record (landing on Mount Everest at 8,848 metres), and is fully operational in high and hot environments.

FFAR – 4 Folding-Fins Aerial Rockets

The family of 4 Folding-Fin Aerial Rocket (FFAR) was the first type of rocket motors developed in the late 1940s.

The early FFAR rockets (with rocket motors Mk4 for aircraft and the Mk40 for helicopters) were conventional 70 mm diameter unguided rockets, comprising a solid-propellant motor with 4 folding fins and an appropriate warhead.

These were later replaced by the more performing rocket motors FZ67 (for fixed wings aircraft) and FZ68 (for helicopters)

WA – Wrap Around Rockets

The Wrap Around (WA) fin assembly was developed from the previous 2.75 inch Mk40 motor-based folding fin aerial rocket in the 1960s in order to increase stability during flight and precision (especially for rotary wings).

The WA rocket motor is suitable for both, rotary and fixed wing aircraft.
