The British submarine HMS Artful can stay submerged for 25 years without having to surface for air

HMS Artful can stay underwater for up to 25 years without surfacing – its nuclear reactor only needs serviced once per quarter-century, and the submarine can produce breathable air and water from the sea around it.

The crew just have to remember to pack a LOT of DVD box sets.

The 320-foot, 7,400-tonne sub, made by British defence firm BAE Systems, displaces as much water as 65 blue whales, and can circumnavigate the world without surfacing.

It has to surface once every three months, largely to load its hold with sausages.
