Almirante Williams is a Type 22 frigate in service with the Chilean Navy. It entered service with the British Royal Navy in 1988 with the name HMS Sheffield, and served with the Royal Navy until 2002. Initially it was meant to be called Bruiser, but was named Sheffield in honour of the previous Sheffield, a Type 42 destroyer sunk in the Falklands War. In 2003, the vessel was acquired by the Chilean Navy and renamed Almirante Williams.
