ARTHUR

ARTHUR, short for artillery hunting radar, is a mobile weapon-locating radar system developed through close cooperation between the Swedish and Norwegian armed forces. The original development work was carried out by Ericsson Microwave Systems in Sweden and Norway. After Ericsson Microwave Systems was sold to Saab in June 2006, responsibility for the system moved to Saab AB Electronic Defense Systems and Saab Technologies Norway AS. The system is designed primarily for counter-battery operations. It detects projectiles while they are in flight, analyzes their trajectories, and calculates the likely firing position and impact area. This allows military commanders to identify hostile artillery batteries, warn forces in threatened areas, and direct counter-fire. ARTHUR can distinguish between artillery, mortar, and rocket fire by analyzing characteristics such as projectile speed, range, and trajectory. It can also operate in a fire-direction role, calculating corrections for friendly artillery and, in Sweden, supporting fall-of-shot calibration. ARTHUR was initially developed as a C-band, passive electronically scanned array radar mounted on a tracked Bandvagn 206 vehicle produced by Hägglund & Söner. Later configurations have more commonly been installed on trucks using ISO mounting arrangements. The system is designed for mobility and can be transported by a C-130 aircraft or suspended beneath a heavy-lift helicopter such as a Chinook. This supports deployment with airborne, marine, light, and rapid-reaction forces. The family has evolved through several major configurations. Mod A provided medium-range weapon-location capability. Mod B was developed to meet the British Army's requirement for the MAMBA system and was used operationally in Iraq and Afghanistan. Mod C introduced a larger antenna, longer detection ranges, higher target-processing capacity, and improved accuracy. The latest publicly described configuration, ARTHUR WLR Mod D, extends instrumented range to as much as 100 kilometres, improves accuracy, covers a 120-degree sector, and can track more than 100 targets simultaneously. The British Army received Mod D systems under the local name TAIPAN, replacing its earlier MAMBA systems. The radar has been operated or acquired by armed forces in Europe, Asia, the Middle East, and North America. Users and reported users include Sweden, Norway, the United Kingdom, Canada, the Czech Republic, Denmark, Greece, Italy, Malaysia, Singapore, South Korea, Spain, Ukraine, and Bulgaria. Its employment has included national artillery defense, expeditionary operations, and multinational formations such as the Nordic Battle Group. In that context, ARTHUR can help identify the source of indirect fire directed toward civilian areas and provide warnings to friendly troops. ARTHUR is a defense-system product rather than a consumer brand. Its operational value depends on mobility, rapid deployment, accurate trajectory analysis, digital communications, and integration with artillery command-and-control networks. Because active radar emissions can be detected by electronic intelligence systems, operators must manage exposure through tactics such as minimizing transmission time, using terrain and radar horizons, moving frequently, and deploying systems in mutually protective groups.

ARTHUR was created as a joint Nordic defense-development effort involving the Swedish and Norwegian armed forces. Ericsson Microwave Systems conducted development work in both countries, with the system intended to provide a mobile means of locating hostile field artillery. The name is an acronym for artillery hunting radar, reflecting its primary counter-battery function. The first-generation system used a passive electronically scanned array operating in the C band. Its original carrier was the Bandvagn 206, a tracked articulated vehicle associated with Hägglund & Söner. This vehicle gave the radar mobility over difficult terrain and made it suitable for field artillery formations and rapidly deployable units. Later installations were increasingly mounted on trucks fitted with ISO fasteners, allowing the radar shelter and associated equipment to be integrated with different vehicle fleets. In its weapon-locating role, ARTHUR tracks the upward portion of incoming projectile trajectories. It uses the observed flight path to calculate the probable location of the firing weapon and the projected impact area. The system can support warnings to troops in the threatened zone and can pass information to artillery command networks for counter-fire. It can also classify the general type of weapon involved, including guns, mortars, and rocket systems. In fire-direction mode, it calculates the expected impact point of friendly rounds and generates corrections for artillery crews. Swedish forces have additionally used the system for fall-of-shot calibration. The first operational configuration, Mod A, offered medium-range location of artillery and mortar positions. Mod B was developed for the British Army's MAMBA requirement. In British service, MAMBA was used in Iraq and Afghanistan and was reported to have achieved approximately 90 percent availability. Mod B improved the system's effective ranges and accuracy compared with the original configuration while retaining its mobile field role. Mod C introduced a larger antenna and further increases in detection range, accuracy, and processing capacity. It could detect guns at approximately 31 kilometres, mortars at approximately 55 kilometres, and rockets at distances of roughly 50 to 60 kilometres depending on projectile size. It could process targets at a rate of up to 100 per minute. Mod C became the basis for deployments by several national armed forces, including Italy, South Korea, and Bulgaria. A major corporate transition occurred in June 2006, when Ericsson Microwave Systems was sold to Saab. Development and production responsibility subsequently became associated with Saab AB Electronic Defense Systems and Saab Technologies Norway AS. The system therefore continued under Saab's defense-electronics organization rather than remaining an Ericsson product. The latest configuration described in the referenced material is ARTHUR WLR Mod D. It offers an instrumented range of up to 100 kilometres, improved accuracy, a 120-degree coverage arc, and simultaneous tracking of more than 100 targets. The British Army selected this generation under the name TAIPAN. Five systems had been delivered and accepted by July 2024 for the 5th Regiment Royal Artillery, replacing the preceding MAMBA capability. ARTHUR has spread beyond its Nordic origins through sales, leases, transfers, and operational deployments. Canada leased systems for operations in Afghanistan. Italy initially leased systems for operations in Iraq before deciding in 2009 to purchase them; the Italian Army was using five systems by at least 2013. South Korea reportedly acquired Mod C systems in 2007 and received a follow-up order from Saab in 2011, with approximately 20 systems positioned near the Korean Demilitarized Zone. Other reported users include the Czech Republic, Denmark, Greece, Malaysia, Singapore, Spain, Ukraine, and Bulgaria. Norway has planned replacement of its systems with Thales Ground Master 200 MM/C radars. The radar's mobility allows transport by C-130 aircraft or carriage beneath a heavy-lift helicopter such as a Chinook. This gives it relevance for airborne and marine formations as well as conventional artillery brigades. Its main operational vulnerability is electromagnetic detectability: an adversary with electronic-support or electronic-intelligence capability may locate an emitting radar and attack it with artillery, aircraft, anti-radiation weapons, electronic countermeasures, or direct fire. Users mitigate this risk by limiting transmission time, using terrain to screen emissions, moving frequently, operating individual radars separately, and providing local protection.
