British Surface Action Group

A British Surface Action Group (SAG) was a Royal Navy formation responsible for commanding multiple surface warships—such as destroyers, cruisers, and sometimes aircraft carriers—during naval operations. These groups coordinated naval battles, patrols, and fleet movements, providing a unified command structure. Their role evolved over time, especially during the World Wars and Cold War, to enhance maritime defense and offensive capabilities. In essence, a SAG acts as the operational unit that manages surface ships working together to achieve strategic naval objectives, ensuring effective deployment, communication, and combat readiness in maritime warfare.
