Littoral Response Group

A Littoral Response Group (LRG) is a Royal Navy task group usually consisting of one or two amphibious warfare ships (supported by other Royal Navy elements if required and available), a company of Royal Marines and supporting elements primarily tasked with littoral warfare from the littoral areas. They were first deployed in 2020 and have been described by the Royal Navy as being more flexible and agile compared to previous amphibious task groups with an emphasis on forward-basing, precision strike capabilities, high mobility, modern command and control technology, networked autonomous systems and deception capabilities. Multiple LRGs were to be able to combine to form a more substantial Littoral Strike Group (LSG) and also join a UK Carrier Strike Group to form an Expeditionary Strike Force.

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. 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. At the same time, it was also proving to be a challenge to keep the Royal Fleet Auxiliary's aging aviation support ship, RFA Argus, in service. In July 2025 it was reported that the Maritime and Coastguard Agency (MCA) and Lloyds Register (LR) had deemed Argus "unsafe to sail" meaning that, at minimum, further work would be required to render the 45-year old vessel seaworthy. In early 2026, it was confirmed that Argus was to be scrapped. These gaps brought into question the entire concept of the navy's ability to deploy two, and even one, littoral response groups.
