OVERVIEW: The ARTHUR detects hostile artillery by tracking projectiles in flight, a mobile Counter-Battery radar.
DETAILS: This field artillery acquisition radar was developed for the primary role as the core element of a brigade or division level counter battery sensor system. The vehicle carrying the radar was originally a Bandvagn 206 developed and produced by Hägglunds, but is now more often delivered on trucks with ISO fasteners. ARTHUR can operate as a stand-alone medium-range weapons locating radar or a long-range weapon locating system, consisting of two to four radars working in coordination. This flexibility enables the system to maintain a constant surveillance of an area of interest. It can be carried by a C-130 or slung under a heavy lift helicopter such as a Chinook. Its air mobility allows it for use by light and rapid reaction forces such as airborne and marine units.
NOTES: ARTHUR is an acronym for "Artillery Hunting Radar", a mobile radar system originally developed jointly for and in close co-operation with the Norwegian and Swedish armed forces. The upgraded ARTHUR Mod B meets the British Army's MAMBA requirement for locating guns, mortars or rockets. Known users are Sweden, Norway, Denmark (being phased out under the last agreement for the Danish Defence), Canada (leased), Italy (leased), Czech Republic, Greece, Spain, Singapore, Malaysia, UK (leased Mod A until MAMBA available). South Korea has reportedly purchased ARTHUR Mod C in 2007, in 2011 Saab received a follow up order.
