The Falklands replaced vulnerable at-sea supply ships

What role did the Falkland Islands play as a Royal Navy base during the Second World War?

They provided protected repair and fuel support, freeing warships to hunt raiders instead of escorting vulnerable supply ships at sea.

The Falklands served as more than a nominal fleet base. HMS Cumberland could refit there, and fuel and support ships could wait inside a defended harbor. Germany needed vessels such as Altmark to sustain distant raiders at sea, exposing both the raider and its supply network. British protected logistics released destroyers and cruisers to search for enemy surface ships instead of guarding mobile replenishment vessels.
