The Eurocopter (now Airbus Helicopters) AS550 Fennec (now H125M)[1] 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.

Design

Operational history

As a result of the Vienna Treaty,[which?] military variants of the Écureuil were marketed under a separate designation; thus from 1990 onwards the type was marketed as the Fennec.[2]

In February 2007, India selected the AS550 C3 Fennec over the Bell 407 helicopter in a deal for 197 helicopters worth US$500 million.[3] This deal was suspended in June 2007 because of concerns of alleged corruption in the bidding process, and cancelled outright on 6 December 2007.[4] The contract is now being re-competed, and the AS550 C3 is among the helicopters competing for the deal. However India chose Kamov Ka-226T over AS550 C3 in the refreshed tender.[5]

On 20 January 2011, Royal Malaysian Navy PASKAL commandos rescued a hijacked Malaysian chemical tanker and its crew from Somali pirates. A Fennec helicopter provided reconnaissance and aerial gunfire to keep the pirate's mother ship at bay while commandos boarded the tanker.[6]
