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 can combine to form a more substantial Littoral Strike Group (LSG) and they can also join a UK Carrier Strike Group to form an Expeditionary Strike Force.[1]
