The Crotale missile defence system can be fitted on a variety of chassis types and launched against targets overland or overwater. The French Air Force, Finnish Army and French Navy are just some of the users of this multi-dimensional system which began its design phase in 1967 and entered production in 1978. Four Crotale missile defense systems can be networked to cooperate in unison, providing an effective "Friend-Or-Foe" net against inbound aerial threats including cruise missiles. The Crotale missile has proven highly maneuverable for its role and can reach speeds in excess of Mach 3.5 with an engagement range out to 11 kilometers (6.8 miles).
Fire control utilizes multiple sensors with passive optics and radar working alongside electronic countermeasure systems. The target detection and acquisition systems are completely automated to achieve the fastest response time by the crew. The highly adaptable system can be ported onto a variety of chassis requirements some of which have been seen on Multiple-Launch Rocket Systems (MLRSs), 6-wheeled Armored Fighting Vehicles (AFVs) and 4-wheeled armored cars.
The Crotale "NG" ("Next Generation") variant became an upgraded production mark when it was introduced with Finland. Other marks have included the HQ-7 Chinese reverse-engineered model then copied by the Iranians. Saudi Arabia operates the SICA "Shahine" R460 series. The Crotale Mk.III is the latest in the Crotale line and began testing around 2008 - this version is capable of engaging smaller drone aircraft with accuracy.
