Britain Launches First Autonomous Squadron with Uncrewed Surface Vessels for Surveillance and Fleet Protection.

The Royal Navy has established its first autonomous squadron to deploy Kraken and Rattler uncrewed surface vessels alongside warships, expanding Britain's ability to conduct maritime surveillance, fleet protection and high-risk missions. Announced on 9 November 2026, the move marks a shift from experimental drone boats to an operational capability that could extend naval reach without exposing crewed warships to unnecessary threats. Operating from Portsmouth, the squadron will use high-speed autonomous vessels for reconnaissance, surveillance and fleet protection, with potential future roles in maritime strike and counter-drone defence. Their integration could give Britain and NATO a more flexible, resilient naval force in contested waters.

Key Tactical Insights:

• Expanding Maritime Surveillance and Fleet Protection: The Royal Navy’s integration of Kraken K3 Scout and Rattler uncrewed surface vessels into its 1st Autonomous Squadron could extend surveillance coverage, improve early threat detection and strengthen the protection of high-value warships without committing additional crewed vessels to every mission.
• Enhancing Distributed Naval Operations and Remote Coordination: Operating Kraken and Rattler USVs alongside conventional warships enables the Royal Navy to develop coordinated maritime screening, reconnaissance and shadowing tactics, potentially allowing naval commanders to monitor multiple areas simultaneously while reducing personnel exposure in contested waters.
• Strengthening Hybrid Fleet Capabilities and Counter-Drone Defence: The modular K3 Scout offers potential integration of advanced sensors, including Saab’s Giraffe 1X radar, to support forward air-threat detection and future counter-drone operations. Such capabilities could extend a naval task group's situational awareness and improve defensive coordination, although radar-equipped configurations remain experimental.

The Royal Navy has taken a significant step towards a more capable and adaptable surface fleet with the establishment of its first autonomous squadron. In an official announcement on 9 November 2026, the service confirmed that the new unit will operate Kraken and Rattler uncrewed surface vessels independently and alongside naval task groups. The initiative forms part of Britain's £1.5 billion investment over four years in hybrid naval operations, strengthening maritime security and future operational readiness.

Royal Navy Establishes Permanent Autonomous Capability at Portsmouth

The 1st Autonomous Squadron was formally commissioned on 5 November at His Majesty's Naval Base Portsmouth, marking the transition from experimental uncrewed maritime systems towards a dedicated frontline capability. Commanded by Commander Helen Coxon, the squadron comprises approximately 180 personnel organised into two watches to support round-the-clock operations. The new formation succeeds Project Beehive, the Royal Navy's programme for testing autonomous and crewless vessels, and will operate independently or alongside naval task groups and allied forces. The commissioning ceremony included a demonstration of Kraken and Rattler boats manoeuvring around Portsmouth Harbour under control from a remote operations hub. According to the Royal Navy, the initiative will strengthen the integration of crewed and uncrewed platforms while accelerating the introduction of emerging technologies into operational service.

Kraken K3 Scout and Rattler USVs Expand the Royal Navy's Operational Options

A central element of the new squadron is the British-developed Kraken K3 Scout, a high-performance, modular uncrewed surface vessel designed to undertake maritime surveillance, reconnaissance, force protection and logistics missions, with provision for precision-strike capabilities. Manufactured by Kraken Technology Group, the 8.4-metre vessel can reach speeds of up to 55 knots, travel approximately 650 nautical miles at 25 knots and accommodate payloads weighing up to 600 kilograms, according to company specifications. Its open architecture allows different mission equipment, including surveillance sensors and other specialised payloads, to be integrated without extensive platform redesign. In March 2026, the Royal Navy awarded Kraken a £12.3 million contract for 20 uncrewed boats under Project Beehive, supporting operational experimentation and the development of new naval tactics. The platform's adaptability offers the Royal Navy a potential means of extending maritime awareness and force protection without committing a large crewed warship to every mission.

Complementing the K3 Scout is the Rattler USV, developed by SYOS Aerospace, which has already demonstrated its value in remote maritime operations and coordinated surveillance exercises. The 7.2-metre vessels were extensively tested during 2025, including a Royal Navy demonstration off Scotland in which five Rattlers were remotely controlled from approximately 500 miles away. Operating alongside crewed naval assets, the boats successfully simulated the escort and shadowing of foreign warships, demonstrating the potential for distributed surveillance and coordinated operations. Within the new squadron, Rattler provides an important platform for operator training, tactical development and the refinement of uncrewed fleet operations. Together, Kraken and Rattler offer complementary capabilities that could increase operational flexibility, sustain surveillance coverage and reduce the demands placed on conventional naval platforms.

Modular USVs Offer New Opportunities for Fleet Protection and Counter-Drone Operations

The introduction of these vessels also creates opportunities for the Royal Navy to develop more distributed maritime defence capabilities. Beyond conventional surveillance, modular USVs could support forward screening, protection of high-value naval units and the integration of specialised counter-uncrewed aerial system technologies. An example is the experimental collaboration between Kraken Technology Group and Saab UK, announced in October 2026, which integrated Saab's Giraffe 1X three-dimensional surveillance radar onto a K3 Scout to explore the detection and tracking of airborne threats. Although the radar-equipped configuration remains experimental and has not been confirmed as standard equipment for the new squadron, it demonstrates the platform's potential to operate as a forward sensor node supporting wider naval air-defence networks. Future payload development could also expand maritime strike options, although the commissioning announcement does not confirm the operational deployment of armed K3 Scout variants. For Britain, the broader significance lies in combining adaptable, potentially lower-cost uncrewed platforms with advanced sensors, secure command-and-control systems and established warship capabilities to strengthen fleet resilience.

The establishment of the 1st Autonomous Squadron represents an important milestone in the Royal Navy's modernisation and reinforces the United Kingdom's commitment to maintaining a technologically advanced maritime force. Supported by the Royal Navy's Capability Accelerator, Navy Develop and the Disruptive Capabilities and Technologies Office, the programme demonstrates how British defence innovation can move emerging technologies from experimentation towards frontline use. As Kraken and Rattler vessels become increasingly integrated with naval operations, their effectiveness will depend on reliable communications, operational testing and the successful development of mission-specific capabilities. The new squadron nevertheless establishes a foundation for a more flexible British fleet, combining the endurance and firepower of conventional warships with the adaptability and scalability of autonomous maritime systems to support UK and NATO security.
