Royal Navy to send HMS Dauntless to Falkland Islands David Cameron has responded that the sovereignty of the islands is not for negotiation. Sending the £1 billion Dauntless on her first mission to the area will reinforce Britain's position although it will cause difficulties for the Foreign Office which is trying to downplay the rhetoric. Admiral Lord West, the former First Sea Lord and Falklands veteran, said the Type 45 has an "amazing anti-air warfare capability." He also sent a warning to the Buenos Aires government. Should there be any foolish nonsense from Argentina, Dauntless can sit just off the airfield and take down any aircraft coming in. It's a game-changing capability. A Navy Spokesman said: "The Royal Navy has had a continuous presence in the South Atlantic for many years. The deployment of HMS Dauntless to the South Atlantic has been long planned, is entirely routine and replaces another ship on patrol. Dauntless will replace the ageing Type 23 frigate Montrose. Earlier this month the Navy sent Daring, the first Type 45, to the Arabian Gulf as tensions with Iran increase.
