was suffering severe crewing problems, as well as a labour force disruption, meaning the manning of its three vessels was facing serious challenges. This brought into question the entire concept of the navy's ability to deploy two littoral response groups.


Background

The LRG concept responded to a global shift in interstate competition from
total war Total war is a type of warfare that includes any and all (including civilian-associated) resources and infrastructure as legitimate military targets, mobilises all of the resources of society to fight the war, and gives priority to warfare ov ...
s 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. Whilst the LRG concept was first announced in 2019, the Royal Navy deployed similar task groups over the past decade as part of the
Response Force Task Group The Joint Expeditionary Force (Maritime) (or JEF(M)) (formerly the Response Force Task Group (RFTG), and prior to that the Joint Rapid Reaction Force (JRRF)), is the Royal Navy's contribution to the Joint Expeditionary Force (JEF) maintained at ...

Composition

An LRG typically consisted of an and a , along with a company of 250 Royal Marines. However, as of 2024, both ''Albion''-class vessels were being maintained in reserve and the MOD's Minister of State, James Cartlidge, stated that it was anticipated that, although

was to complete a long-term refit in 2024, she would nevertheless only be activated "if required". 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. This was to have been a stopgap solution until the entry into service of the new Multi-Role Support Ships (MRSS) in the 2030s. However, in July 2022, it was reported that the future Littoral Strike role would be assumed by RFA ''Argus'' after a refit to convert her. Escort will be provided by at least one frigate or destroyer. 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

The Royal Navy has had two operational LRGs: Littoral Response Group (North), which is based in Europe, and Littoral Response Group (South), based in the Indo-Pacific region.


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. Later in the year, it was indicated that both ''Albion''-class vessels would be retired. 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
