In August, HMS Prince of Wales broke down off coast of the Isle of Wight on her way out of Portsmouth, and the navy later confirmed that the starboard propeller had malfunctioned with the coupling that held it in place breaking. The £3bn vessel was meant to take part in flight trials and diplomatic visits in the US, but was instead towed back into Portsmouth Harbour. She remained in place until October, when she was eventually taken to Rosyth in Scotland for repairs. It was expected that she would be out of action for an extended period, and now the Royal Navy has conceded that the warship won't be returning to Portsmouth anytime soon.
