[1] However, as of late 2024, the future of the entire LRG concept was at best uncertain since, in November 2024, the newly elected Labour government indicated that both of the Royal Navy's Albion-class landing platform dock vessels would be removed from service by March 2025.

[2] Simultaneously, the Royal Fleet Auxiliary was suffering severe crewing problems, as well as a labour force disruption, meaning the manning of its three Bay-class landing ship dock vessels was facing serious challenges.

[6] The LRG concept responded to a global shift in interstate competition from total wars to persistence through limited positional warfare.

[8] A Littoral Response Group is defined as a “bespoke force assigned to a geographic area, that contains dedicated shipping, helicopters and boats".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.

[10][11] They could also be used to carry out raiding missions, demonstrations of force, evacuations and precision strikes inland from the littoral zone.

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.

LRG (N) was first deployed in March 2021 on a three-month mission to the North Atlantic and Baltic Sea and took part in NATO's BALTOPS large-scale military exercise.

Argus provided the task group enhanced medical facilities and a flight deck with Merlin and Wildcat helicopters.

[24] In March 2023, the Royal Navy established a base in Norway for LRG(N) personnel, named Camp Viking.

During the exercise, commandos from RFA Mounts Bay located and "destroyed" anti-access/area denial systems which granted NATO forces access to northern Norway.

"[35][36] In July 2024, Lyme Bay, Argus and troops from 40 Commando deployed to Australia for exercise "Predators Run" involving US and Australian forces.
