Arthur Counter-Battery Radar: 13 NATO Armies’ Standard for Locating Enemy Artillery — Technical Analysis

Arthur (Artillery Hunting Radar) is Saab’s mobile counter-battery radar system. It detects artillery, mortar and rocket projectiles in flight, computes their trajectory in reverse, and delivers the firing position coordinates to friendly fire direction centres within seconds of a round being detected. Operating in 13 nations — including UK, France, Norway, Denmark, Sweden, Finland, Ukraine and Australia — Arthur is the most widely deployed counter-battery radar in NATO and has received renewed orders following its combat employment in Ukraine.

Why Counter-Battery Radar Matters

In conventional warfare, suppressing enemy artillery is a persistent challenge. A gun or mortar position that fires and moves — “shoot and scoot” — can be almost impossible to locate through observation. Counter-battery radar (CBR) solves this by watching the sky rather than the ground: it detects the projectile a fraction of a second after launch, tracks it through the first portion of its trajectory, and extrapolates backward to the point of origin. The entire computation takes less than ten seconds. That origin coordinate is then transmitted to friendly artillery, which can engage the enemy position before it has time to relocate. Modern armies treat CBR as a force multiplier for all artillery-supported operations, not just counter-battery tasks.

Ukraine Combat Use

Arthur has been employed by Ukrainian forces throughout the ongoing conflict. Reports from the battlefield describe the system being used to locate Russian artillery and mortar positions, with the derived coordinates fed to Ukrainian counter-battery fires. The operational tempo — Russian artillery firing tens of thousands of rounds per day at peak — provided a genuinely demanding environment for the system’s tracking algorithms, and Arthur’s continued use by Ukraine after more than two years of conflict suggests satisfactory performance under those conditions.

Strengths

• 100 km range — covers all categories of towed and self-propelled artillery
• Simultaneous tracking of multiple independent projectiles from different firing positions
• Mobile design — rapid deployment and frequent position changes to avoid counter-detection
• 13 NATO nations validated operational approval

Limitations

• Radar emissions are detectable: active operation can reveal the system’s position to enemy direction-finding equipment
• High acquisition cost positions it primarily for brigade-level and above deployment

Competitive Landscape

Why It Matters for Turkey

ASELSAN’s TAFICS (Artillery Fire Notification and Detection System) is Turkey’s indigenous counter-battery radar and is in Turkish Army service. TAFICS addresses the same mission as Arthur; the competitive question is range and multi-target capacity. Published open-source data suggests TAFICS operates at shorter detection ranges than Arthur’s 100 km figure. For Turkey’s artillery-intensive ground forces, a counter-battery radar with Arthur-equivalent range would provide a decisive advantage in any engagement involving long-range artillery systems. The export case for TAFICS would similarly benefit from publicly demonstrated performance at range comparable to the NATO standard.

Bottom Line

Arthur has become the reference standard for counter-battery radar in NATO because it combines a 100 km detection range, simultaneous multi-target tracking and a mobility design suited to the high-tempo fires environment of peer-on-peer warfare. Ukraine’s two-plus years of operational use under the most demanding artillery conditions in Europe since 1945 is the most comprehensive real-world validation any radar system could receive. New orders continue to follow. Turkey’s TAFICS represents the right indigenous approach; matching Arthur’s range and closing the gap in international visibility are the next milestones.
