US firm Leidos has revealed a next-generation commando insertion craft concept developed for the Royal Navy as part of the UK Commando Force (UKCF) modernization program.
With a speed of 40 knots (74 kilometers/46 miles per hour), the “Sea Dagger” is purported to be the “first craft of its size to combine speed, range, vehicle delivery and modular mission systems into a single platform.”
It is the result of a collaboration among Leidos Naval Architects and military subject matter experts, the Royal Navy, as well as the UKCF. It seeks to field 24 medium surface insertion craft that can carry Commando Strike teams, light tactical mobility platforms, offboard systems, and medium combat loads over long distances, supported by training and in-service sustainment.
The company did not release further specifics beyond stating how the craft is being developed to prioritize operational resilience, and is being built with a “unique combination” of naval architecture, advanced sensors, weapons, and command and control capabilities influenced by the modern battlefield.
Additionally, the craft is intended for continuous operation under stress, disruption, or attack in contested environments.
Apart from supporting the navy’s modernization plan, it is also aligned with the AUKUS Pillar 2 maritime autonomy objectives and the UK Strategic Defence Review meant to “restore Britain’s war-fighting readiness.”
“Sea Dagger represents a pivotal step in equipping the UK Commando Force with the capability to operate with greater agility, survivability and intent in a complex and congested maritime environment,” Adam Clarke, senior VP and chief executive at Leidos UK & Europe, said.
“The Leidos design reflects our commitment to delivering resilient, future-ready platforms that can adapt to the complexities of modern warfare, ensuring capability, availability and operational advantage from day one. I am delighted that Leidos is at the forefront of shaping the maritime marketplace, domestically and internationally.”
