Littoral Response Group

The LRG concept responded to a global shift in interstate competition from total wars to persistence through limited positional warfare. It also responded to the proliferation of anti-ship missiles, man-portable air-defence systems (MANPADS) and sophisticated NPADS) and sophisticated Intelligence, Surveillance, and Reconnaissance capabilities which have rendered traditional large-scale amphibious assaults increasingly hazardous. This made them an unattractive option to seize and take control of ground in the littoral zone, an area of increased importance due to the rise in population centres and economic interests in those areas. ==Overview==

Role The LRG concept provided the UK options in an era of sub-threshold competition, a "grey zone" where nation states and actors compete in a hostile manner using tactics below the threshold of war. They could also be used to carry out raiding missions, demonstrations of force, evacuations and precision strikes inland from the littoral zone. The Royal United Services Institute provided four example uses for a Royal Navy LRG in its publication, titled Requirements for the UK’s Amphibious Forces in the Future Operating Environment, which are: • The removal of a Russian force that has landed on the Norwegian archipelago of Svalbard to prevent the installation of area denial (A2AD) systems. • A reinforcement to prevent the seizure of Gotland, Åland or Bornholm in the Baltic by Russia. • The seizure of the Iranian island of Abu Musa in the Strait of Hormuz to prevent mine-laying and attacks on commercial shipping by the Iranians. • Intervention in Hodeidah, Yemen to prevent a humanitarian catastrophe and reduce the threat to shipping in the Red Sea. Composition An LRG typically consisted of an and a , along with a company of 250 Royal Marines. In late 2024, it was indicated that both Albion-class vessels would be removed from service by March 2025, thus ending this capability in the Royal Navy. In 2021, the Ministry of Defence announced it would be investing £50 million into upgrading one of the Bay-class landing ship docks to better facilitate its role within the LRG concept, with upgrades to its command and control facilities and the installation of a permanent hangar. Escort will be provided by at least one frigate or destroyer. However, this approach was effectively abandoned as of 2025 when Argus was laid up due to her poor condition and later confirmed for scrapping. Fixed and rotary-wing remotely-piloted air systems (RPAS) are an integral part of the LRG concept. These systems provide commandos with increased strike, surveillance and logistical options, increasing their lethality, survivability and sustainability. == Operational history ==

Up to 2025, the Royal Navy sought to maintain two operational LRGs: Littoral Response Group (North), which is based in Europe, and Littoral Response Group (South), which had been planned to be based in the Indo-Pacific region. However, given the retirement/unavailability of vessels, as of 2025 it is likely that, at best, only one Littoral Response Group can now be maintained. Littoral Response Group (North) Littoral Response Group (North) has been the lead formation, based in Europe, with an area of responsibility in the Atlantic, Baltic and Mediterranean. It has included an , a , a company of 45 Commando Royal Marines and supporting elements. As of 2024, an Albion-class ship would only be made available from reserve "if required", making the group effectively reliant on RFA Mounts Bay on a day-to-day basis. In May, the same task group then participated in Exercise Ragnar Viking alongside the US Navy's amphibious ready group in Norway. Prior to this, both groups carried out joint amphibious drills in Scotland as part of Exercise Wader. 29 Commando Regiment Royal Artillery, 24 Commando Royal Engineers and the Commando Logistics Regiment supported this deployment. Both task groups also joined the UK Carrier Strike Group led by the aircraft carrier for Exercise Strike Warrior. The exercise involved 20 ships, three submarines and 84 aircraft and validated NATO's ability to coordinate a carrier strike group with an amphibious task group. In September 2022, joined the task group for the first time, joining HMS Albion, RFA Mounts Bay, and in the Mediterranean. Argus provided the task group enhanced medical facilities and a flight deck with Merlin and Wildcat helicopters. In March 2023, the Royal Navy established a base in Norway for LRG(N) personnel, named Camp Viking. It will be used to respond to emerging crises in Europe. In March 2024, the task group participated in Nordic Response in Norway. During the exercise, commandos from RFA Mounts Bay located and "destroyed" anti-access/area denial systems which granted NATO forces access to northern Norway. Littoral Response Group (South) Littoral Response Group (South) had been assigned responsibility for operations in the Indo-Pacific, though both ships normally assigned to LRG (S) were usually not available in the region. The commando element is provided by 40 Commando Royal Marines who carried out pre-deployment training in the Mojave Desert in October 2021 in order to prepare them for their role. They trained alongside Dutch Marines who will also be providing part of the LRG. The Commando Logistic Regiment, 30 Commando Information Exploitation Group, 24 Commando Royal Engineers and 29 Commando Royal Artillery also provide components as required. In total, the task group will comprise up to 500 British troops and 120 Dutch troops. On 12 October 2023, the UK deployed LRG(S), consisting of RFAs Argus and Lyme Bay and supported by RAF P-8 Poseidon aircraft operating from RAF Akrotiri, to the Eastern Mediterranean during the Gaza war. In January 2024, Lyme Bay stopped at Port Said, Egypt to deliver 70 tonnes of humanitarian aid for Gaza. In March, Argus and Lyme Bay transited the Red Sea amid the Red Sea crisis, escorted by , and stopped at Kattupalli Shipyard in India for maintenance. In April, the ships participated in a Maritime Partnership Exercise with the Indian Navy's Eastern Fleet in the Indian Ocean. The tasks conducted in the exercise included "tactical manoeuvres, boarding ops, surface engagement against simulated asymmetric threats, cross deck visits & cross deck helo ops." In July 2024, Lyme Bay, Argus and troops from 40 Commando deployed to Australia for exercise "Predators Run" involving US and Australian forces. In September 2024, Argus returned to the U.K. via Cape Town. As of 2025, Argus had been laid up and seemed unlikely to return to sea. == References ==
