This is the astonishing moment a British warship intercepted a Russian submarine at risk of exploding before tracking it through the English Channel .Exclusive footage from Channel 5's new season of 'Warship: Life in the Royal Navy' shows the crew aboard HMS Iron Duke spot the diesel-powered Novorossiysk heading towards British waters.The 230ft-long vessel, manned by a crew of 50, was towed in the North Sea after suffering a reported fuel leak in the Strait of Gibraltar, and was at risk of exploding.Dramatic footage filmed inside the control centre of the Plymouth-based frigate shows the crew identifying the submarine, swiftly informing the captain, before heading to the bridge to scour the horizon for its presence.One crew member spots the submarine with his binoculars, triggering the mission to stalk the vessel and gather intelligence on its capability.
