Kraken and Saab UK Pair K3 SCOUT Uncrewed Vessel with Giraffe 1X Radar to Detect Drones at Sea.

Kraken Technology Group and Saab UK have unveiled an autonomous maritime “drone seeker” that pushes counter-UAS surveillance farther from ships, ports and offshore infrastructure, with the capability announced on 5 October 2026 following sea trials in the UK. By combining the K3 SCOUT uncrewed surface vessel with Saab’s Giraffe 1X radar, the system could give naval forces a mobile early-warning node able to detect aerial threats before they reach high-value assets.

The prototype uses the lightweight Giraffe 1X radar to detect and track low, slow and small airborne targets while operating from an uncrewed surface platform. Deployed individually or as a distributed network, K3 SCOUT could extend the surveillance perimeter around naval formations and strategic sites while reducing reliance on crewed ships as the sole source of counter-drone detection.

On 5 October 2026, Kraken Technology Group and Saab UK unveiled a pioneering autonomous maritime “drone seeker” designed to extend counter-UAS surveillance farther out to sea. The prototype integrates Kraken’s K3 SCOUT uncrewed surface vessel with Saab UK’s Giraffe 1X radar, creating a rapidly deployable maritime early-warning capability against airborne threats. The development comes as NATO members increasingly seek distributed, autonomous and interoperable systems able to protect naval forces, ports and critical infrastructure from the expanding drone threat.

From Autonomous USV to Forward C-UAS Radar Picket

At the heart of the project is the integration of Saab UK’s Giraffe 1X three-dimensional radar into the modular payload bay of Kraken’s K3 SCOUT. The lightweight radar is designed to detect and track airborne threats in real time, including low, slow and small targets, while Saab says the complete Giraffe 1X system weighs less than 150 kg and surveys its entire search volume every second. Kraken and Saab moved from concept to a working prototype within months, conducting sea trials intended to assess radar performance under maritime conditions.

The significance of the programme extends beyond mounting a counter-drone radar on an autonomous boat. K3 SCOUT could effectively operate as an uncrewed forward radar picket, pushing an air-surveillance sensor away from a high-value warship, harbour or offshore installation and closer to the direction from which a threat is expected. Instead of concentrating surveillance capability exclusively aboard large crewed platforms, naval commanders could potentially distribute autonomous sensor nodes across a wider area, expanding the detection perimeter while limiting the exposure of personnel and major combatants. Kraken identifies shipping, ports, offshore energy facilities and critical national infrastructure among the potential applications for the configuration.

That concept becomes more consequential if several autonomous vessels can operate as part of a network. Multiple mobile radar nodes positioned around a naval formation or strategic maritime area could complicate an adversary’s reconnaissance and targeting problem, forcing hostile drones to contend with surveillance from several geographically dispersed sensors rather than one central radar source. This would not make K3 SCOUT an armed counter-UAS platform, the companies have announced a seeker and early-warning capability rather than an onboard effector, but it demonstrates how the sensor component of the counter-drone kill chain could increasingly be detached from traditional crewed ships and distributed across autonomous systems.

Kraken CEO and Founder Mal Crease said the prototype drone seeker vessel is “exactly what the K3 SCOUT was designed to do,” pointing to the platform’s ability to integrate mission-specific payloads for operations in demanding maritime environments. That modularity could prove strategically important: instead of designing a new vessel around each sensor requirement, operators could potentially change mission payloads as operational demands evolve. Kraken describes the approach as part of a wider “hybrid navy” model in which autonomous vessels operate independently or alongside conventional surface ships to extend sensing and early-warning coverage without requiring an additional crewed platform.

There is also a notable industrial dimension. Both K3 SCOUT and Giraffe 1X are manufactured in Fareham, United Kingdom, and Saab says the joint capability was developed in less than seven months. Kraken is simultaneously scaling its industrial footprint after a $175 million Series B funding round that valued the company at $1 billion, with a new 35,000-square-foot facility intended to support production capacity of up to 1,000 vessels per year. Saab, meanwhile, delivered Giraffe 1X systems to the Royal Air Force in September 2026 for counter-drone operations, meaning the Kraken programme is effectively testing how a radar already entering the UK’s wider C-UAS architecture can be transferred into the autonomous maritime domain.

NATO Relevance: Distributed Sensors for a More Resilient Maritime Defence

The wider strategic value of the Kraken-Saab concept may ultimately depend less on the individual USV than on its ability to contribute to a networked Allied sensor architecture. A radar-equipped autonomous vessel becomes considerably more valuable if the tracks it generates can be passed rapidly to ships, shore-based air-defence units, command centres or other effectors. NATO's counter-UAS experimentation increasingly emphasizes exactly this requirement: connecting sensors, command-and-control systems and defensive capabilities using common standards so information can move rapidly between different national and industrial systems. During NATO's 2026 TIE and Baltic Trust exercises, the Alliance specifically assessed sensor-to-C2 integration, tracking continuity, data accuracy and interoperability between counter-drone technologies.

The maritime dimension closely aligns with the direction of NATO's Task Force X initiatives, although no direct NATO involvement in the Kraken-Saab prototype has been announced. Task Force X began by exploring whether commercially available uncrewed maritime systems could be moved rapidly into operational environments, with NATO subsequently reporting that Baltic experimentation demonstrated the ability of autonomous systems to provide meaningful situational awareness at speed and scale. The model has since expanded into the Arctic and Central Mediterranean, where more than 100 uncrewed systems were involved in 2026 experimentation covering intelligence, surveillance and reconnaissance, crewed-uncrewed teaming and counter-UAS missions.

For NATO deterrence and defence, the attraction is not simply the addition of another radar at sea. A distributed network of autonomous sensor platforms could make Allied naval formations, maritime approaches and critical infrastructure more difficult to penetrate undetected while allowing expensive crewed warships to concentrate on missions that specifically require their combat power and personnel. Greater interoperability would also allow a sensor operated by one Ally to contribute to a broader recognised air and maritime picture, strengthening multinational cooperation and potentially creating a denser surveillance architecture across strategically important waters.

Yet important operational questions remain. Kraken and Saab have confirmed maritime trials but have not publicly disclosed detailed detection ranges achieved at sea, performance across different sea states, mission endurance in the radar configuration, communications resilience, track-sharing latency or resistance to electronic warfare. These factors would become increasingly important if the prototype moves from demonstration toward an operational military capability. Maritime radar deployment also introduces challenges involving vessel motion, sea clutter, environmental exposure and maintaining secure connectivity with the wider force, all areas where operational testing will ultimately determine whether the concept can scale beyond the prototype stage.

The Kraken-Saab programme consequently represents more than an unconventional pairing of an autonomous vessel and a compact radar. Its deeper significance lies in the possibility of separating the sensor from the high-value warship, distributing that sensor across autonomous platforms and reconnecting those platforms digitally into a wider Allied defence network. If that model proves operationally resilient and interoperable, autonomous radar pickets could allow NATO navies to expand maritime awareness and counter-UAS coverage without requiring a proportional increase in crewed vessels. The prototype does not yet constitute a complete counter-drone kill chain, but it demonstrates an increasingly relevant direction for future naval warfare: smaller autonomous systems extending the eyes and ears of the fleet while keeping sailors and major combatants farther from the threat.
