Royal Navy submarine HMS Alliance restoration under way

The restoration of a World War II submarine is expected to be completed next year.

HMS Alliance, based at the Royal Navy Submarine Museum in Gosport, Hampshire, is undergoing a £6.75m revamp.

The project, which was awarded £3.4m by the Heritage Lottery Fund, still has a shortfall of £200,000 and efforts continue to raise the cash.

Work on the 1940s submarine, which will be a memorial to 5,300 British submariners who gave their lives in service between 1904 and the present day, started in October 2011 and expected to finish in April 2014.
