Tense BBC drama Vigil has been offering viewers a look inside life on a submarine, with many surprised at what life underwater in the navy is like.
The show, from the producers of Line of Duty, centres around the unusual vanishing of a fishing trawler off the Scottish coast and the death of a crew member on the fictional nuclear submarine HMS Vigil.
It’s inspired many to have a closer look at the enormous military boats, with some wanting to have a look around.
One maritime museum offers visitors the chance to see the last remaining Second World War era submarine, 2Chill reports.
Guests can board the HMS Alliance, exploring the decks and corridors, looking through the original periscope and learning about the people who served onboard, under the sea.
The submarine is based at The Royal Navy Submarine Museum, in Gosport, Hampshire, which also houses subs Holland I and X24.
HMS Alliance featured in the 2017 movie Transformers: The Last Knight, as well as a 2020 Weetabix advertisement.
But before the imposing vessel became a museum ship and movie star, it had a very important part in history.
From October 9, until November 8 1947, the ship was submerged for 30 days in the Atlantic Ocean off the African coast as an ‘experimental cruise to investigate the limits of the snort mast’.
A ‘snort mast’ is a submarine snorkel and is a device which allows people to operate submerged while still taking in air from above the surface.
The submarine was later modernised, removing its deck gun and torpedo tubes, allowing it to be faster.
Around September 30, 1971, a battery explosion occurred on board, while she was at Portland Harbour, which killed one sailor and injured 14 others.
Finally in 2011, HMS Alliance received a share of £11 million from a Heritage Lottery Fund grant to undergo a restoration. This was completed in March 2014, opening to the public at the museum a month later.
Visitors can also discover a ‘Silent and Secret’ exhibition, which features objects that retell hidden conflicts and first-hand accounts from crew onboard, as well as learning how a crew of 65 were fed in a galley the size of a broom cupboard.
