ARTHUR

ARTHUR (an acronym for "artillery hunting radar") is a counter-battery radar system originally developed jointly for and in close co-operation with the Norwegian and Swedish armed forces by Ericsson Microwave Systems in both Sweden and Norway. It is also used by the British Army, under the designation TAIPAN.

It is a mobile, passive electronically scanned array C-band radar for the purpose of enemy field artillery acquisition and 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 Hägglund & Söner, but is now more often delivered on trucks with ISO fasteners.

The radar is now developed by Saab AB Electronic Defense Systems (after EMW was sold to Saab in June 2006) and Saab Technologies Norway AS.

The ARTHUR detects hostile artillery by tracking projectiles in flight. The original ARTHUR Mod A can locate guns at 15–20 km and 120 mm mortars at 30–35 km with a circular error probable of 0.45% of range. This is accurate enough for effective counter-battery fire by friendly artillery batteries. 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.

The upgraded ARTHUR Mod B met the British Army's MAMBA requirement for locating guns, mortars or rockets. It can locate guns at 20–25 km and 120 mm mortars at 35–40 km with a circular probable error of 0.35% of range. MAMBA was successfully used by the British Army in Iraq and Afghanistan, with an availability of 90%.

ARTHUR Mod C has a larger antenna and can detect guns at 31 km, mortars at 55 km and rockets at 50–60 km depending on their size, and locate targets at a rate of 100 per minute with CEP 0.2% of range for guns and rockets and 0.1% for mortars.

ARTHUR WLR Mod D has several improvements, including an instrumented range of up to 100 km, an accuracy of 0.15% of range, and the ability to cover an arc of 120°. The detection range is between 0.8 and 100 km and could possibly increase to 200 km. More than 100 targets can be tracked at the same time. It was delivered to the British Army in 2024, under the designation TAIPAN.

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.
