HMS Anson is the fifth Astute-class nuclear-powered fleet submarine of the Royal Navy. She will be the eighth vessel of the Royal Navy to bear the name, after Admiral George Anson. On 25 March 2010, BAE Systems were given the go-ahead by the government to begin construction on boats 5 and 6 (Anson and Agamemnon), being given a £300 million contract for the "initial build" of boat 5 and "long lead procurement activities" for boat 6.
