An Argentine King George V in the Falklands War

How would a modernized Argentine King George V-class battleship affect the Falklands War?

It would probably become a British submarine target and sink after a larger torpedo attack, creating an even greater political controversy.

A modernized Argentine King George V-class battleship would probably attract the same sort of submarine attention as General Belgrano. Sinking it might require more torpedoes, but the larger ship would probably not escape the same fate. Its loss would then generate sharper political questions about why Argentina had spent so much on the vessel.
