As part of the largest U.K. Commando Force exercise in 15 years, British special operators conducted a submarine insertion off Scotland, making use of a German Navy Type 212A — a boat you can read about in detail here. The maneuvers are the first time since the war in Afghanistan that all of the Commando Force’s specialist elements have operated together. The submarine insertion, conducted at Cape Wrath on September 29, is part of Exercise Strike Warrior, a major NATO drill intended to rehearse allied crisis-response and warfighting operations across the North Atlantic and High North.
The U.K. Royal Navy-led Commando Force specializes in amphibious, littoral, and expeditionary operations. It brings together Royal Marines commandos with specialist elements including reconnaissance, intelligence, targeting, artillery, logistics, and medical capabilities. The force is increasingly focused on smaller, dispersed teams operating across contested littoral environments.

Including elements of the Commando Force, more than 2,000 personnel from the United Kingdom, United States, Germany, Netherlands, Canada, and Norway are currently participating in Strike Warrior, with eight warships and 19 aircraft involved in activity spanning Scotland, the Western Isles, the North-West Approaches, Galloway, the Borders and the North Sea.
The submarine insertion underscores the type of maritime special operations the British Commando Force is now increasingly training to conduct. Personnel from 148 (Meiktila) Commando Forward Observation Battery, Royal Artillery, boarded the unnamed German attack submarine off Scotland before being infiltrated toward the coast. The sub provided intelligence, surveillance, and reconnaissance (ISR) support as the force approached the target area, after which the commandos conducted a discreet small-boat insertion using inflatable raiding craft.

From there, they confirmed the simulated target and coordinated live naval surface fires against a simulated enemy position. Here, firepower was provided by the Portuguese Karel Doorman class frigate Dom Francisco de Almeida, presumably using its Oto Melara 76mm deck gun. Following the engagement, the team was extracted. The complete sequence incorporated submarine infiltration, small-boat insertion, covert reconnaissance and targeting, live naval gunfire, and withdrawal into a single mission profile.
Crown Copyright The German submarine involved is particularly well suited to this kind of mission. Conventional diesel-electric attack submarines (SSK) lack the nuclear-powered endurance and sustained high speed of an SSN, but those characteristics are not necessarily what a short-range clandestine insertion mission requires. Modern SSKs such as Germany’s Type 212A are designed around extremely low acoustic signatures and can remain submerged for extended periods using air-independent propulsion, making them difficult to detect while operating in relatively shallow and constrained waters.
That combination is hugely valuable for special operations. An SSK can approach a coastline covertly, conduct ISR, release a small team and its boats, and withdraw without exposing a large surface vessel or maintaining the high-speed transit capability associated with a nuclear submarine. Its comparatively small size can also be advantageous when operating closer to shore, where depth, seabed conditions and the presence of coastal sensors can constrain larger submarines. Concentionally powered boats are also far cheaper to procure and operate and have smaller crews.

Crown Copyright An SSN offers major advantages for longer-range deployments: far greater endurance, sustained speed, and the ability to carry and support larger payloads over intercontinental distances. These payloads can include dry deck shelters, and swimmer delivery vehicles, allowing allow divers easy exit and entrance while the boat is submerged and at standoff distance from the coast.
But for a mission whose essential requirement is to quietly loiter near a coast, put a small team ashore and leave, an SSK remains a highly relevant platform. Conventional submarines are particularly valuable to the kind of distributed littoral operations NATO is rehearsing in northern European waters.

Crown Copyright The U.K. Royal Navy’s four Upholder class were its last diesel-electric submarines. They were withdrawn in 1994–95 and subsequently transferred to Canada. The Royal Navy today operates an all-nuclear submarine fleet.
The Upholders were also particularly suited to inshore operations, reconnaissance, and other missions demanding extreme quietness and maneuverability.

Ed Early/Released With this in mind, TWZ has, in the past, examined whether the U.S. Navy should complement its all-nuclear submarine fleet with advanced conventional boats. Sweden’s Gotland demonstrated the value of these kinds of boats when it was leased to the U.S. Navy for adversary training and proved exceptionally difficult for American ASW forces to detect.

Kitchner/Released Returning to the Cape Wrath drill, the 148 Battery operations officer involved explained that “This level of complexity and coordination of live assets has not been achieved by 148 for nearly 30 years.”
“We wanted to demonstrate to our partners across the United Kingdom Commando Force, wider U.K. Defense and NATO SOF community the type of missions we are prepared to execute against future threats,” the officer added.

Crown Copyright Multinational integration is central to the exercise. Strike Warrior is testing the ability of the British Commando Force to plug into a much larger allied force in which submarines, surface combatants, aircraft, drones, and small specialist teams can contribute different parts of the same operation.
Earlier in Strike Warrior, 148 Battery also directed fires from the Dutch Karel Doorman class frigate HNLMS Van Amstel and Royal Canadian Navy Halifax class frigate HMCS St. John’s after establishing observation posts. Those ships were operating as part of Standing NATO Maritime Group One.

Crown Copyright The exercise also provides a snapshot of how Britain’s commandos have evolved since their intensive employment in Afghanistan. The Royal Marines’ Future Commando Force concept emphasizes smaller, more dispersed formations capable of operating in contested littoral environments, with greater reliance on maritime mobility, uncrewed systems, long-range fires, and allied capabilities.
Strike Warrior combines those elements, with the exercise including amphibious landings, boarding operations, intelligence and surveillance missions, maritime security, and anti-submarine warfare, alongside drone missions involving strikes and combat resupply. Other elements have practiced establishing protected medical facilities.
The geography of Strike Warrior is equally significant. The exercise extends across Scotland and its surrounding waters, including the Western Isles and out into the North Sea, placing the Commando Force in the maritime environment connecting the highly strategic North Atlantic, Norwegian Sea, and northern European approaches.
That region has become increasingly important to NATO planning because of the difficulty of monitoring and controlling such a large maritime battlespace. Submarines, maritime patrol aircraft, surface combatants, drones, and long-range weapons all have roles to play, while the geography provides numerous opportunities for small forces to operate from the coast and islands.

Crown Copyright The United Kingdom has been repeatedly using the region and the wider High North as a training ground for this type of activity. Earlier this year, British commandos conducted a submarine insertion during Exercise Cold Response in Norway using the German Navy’s Type 212A submarine U-35. That also involved submarine infiltration, small-boat deployment, establishment of an observation post, and the direction of allied naval fires.

Crown Copyright Strike Warrior expands that concept considerably and across a much larger battlespace, providing an opportunity to test not simply individual capabilities but the ability to combine them during a sustained NATO exercise.
The exercise began September 28 and concludes October 9.
For the British Commando Force, the significance extends beyond the dramatic imagery of troops emerging from a German submarine at Cape Wrath. After years in which British commandos were heavily committed to land-based counterinsurgency operations, the exercise is intended to put them firmly back in a maritime and high-end warfighting context.
This is the kind of operation that the U.K. Commando Force is now preparing to conduct alongside NATO partners in the increasingly contested waters of the North Atlantic and High North.
