The Fennec's design is centered around its lightweight and compact structure, making it an ideal fit for deployment on ships with helipads, such as destroyers or aircraft carriers. This allows for greater flexibility in mission planning and execution, as the Fennec can be easily transported and deployed from a variety of naval vessels.^[2]

The Fennec comes in two distinct variants, each catering to different operational requirements. The single-engine variant is optimized for simplicity, reliability, and reduced maintenance, making it an excellent choice for smaller-scale operations or special forces missions. In contrast, the dual-engine variant offers increased power andredundancy, making it better suited for more demanding missions, such as heavy-lift transport or combat operations.^[3]

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.^[4]

AS555 helicopters were delivered toFrench Air Force between February 1988 and March 1994, and as of 2018, 40 of them remain operable. 17 AS555 Fennecs delivered to theALAT on January 1990 and were assigned to the 6th Squadron of Utility Helicopters at the Le Luc Training School, used for training and liaison missions.

TwelveAS550 C2 helicopters were purchased by theRoyal Danish Air Force in 1987, with the first helicopters delivered on August 1990. Due to change in geopolitical environment following thecollapse of the Soviet Union and the end of theCold War, the Fennec helicopters were gradually repurposed for other tasks, primarily observation and light transport duties. In 2003, they were primarily employed by theEskadrille 724. In 2002, 3 Danish Fennec helicopters were deployed toMacedonia duringOperation Amber Fox. In December 2005, Fennec helicopters were deployed to support the Danish forces inIraq and from August 2007, 4 more were deployed to the troubled country as a replacement for the withdrawn ground troops. In 2008, 4 Fennec helicopters were deployed to the Danish forces inAfghanistan. As a result of various defense agreements, the number of active Fennecs in the Air Force has been reduced to 8 in 2006.

In 1992, four units ofAS555 AF Fennec were delivered to theMexican Naval Aviation.^[5]

AS555 Fennec helicopters were acquired by theArgentine Navy following the circumstances caused by theFalklands War, asUnited Kingdom had blocked the sales ofWestland Sea Lynx toArgentina. Although they had acquired two of ten Lynx helicopters ordered, the first one was accidentally decommissioned during the 1982 conflict and the second one was sold to Denmark after being unable to acquire parts to keep it operational. Due to limited military budget, theEurocopter AS555-SN Fennec was chosen to succeed the Lynx, with first four AS555-SN units arriving in 1996.^[6]

In February 2007, India selected theAS550 C3 Fennec over theBell 407 helicopter in a deal for 197 helicopters worth US$500 million.^[7] This deal was suspended in June 2007 because of concerns of alleged corruption in the bidding process, and cancelled outright on 6 December 2007.^[8] The contract is now being re-competed, and the AS550 C3 is among the helicopters competing for the deal. However India choseKamov Ka-226T over AS550 C3 in the refreshed tender.^[9]

On 20 January 2011,Royal Malaysian NavyPASKAL 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.^[10]
