The British are sending their new state of the art destroyer...the HMS Dauntless...to the disputed Falklands/Malvinas islands.
The deployment of the Type 45 destroyer will be her maiden voyage...and she replaces the HMS Montrose.
However...UK Admiral Lord West claims the voyage is not a ramping up...for possible hostilities.
Type 45s have anti-air missiles, helicopter decks large enough for a Chinook...can carry 60 troops...and evacuate as many as 700 people.
AND: UPDATE : The Brits claim that Buenos Aires may be planning a defacto economic blockade of the islands...by cancelling all flights.
The only air link to the Malvinas is one weekly flight on LAN from Chile.
