Warship: Life at Sea - Season 3

Return of the documentary following the ups and downs of everyday life for a Royal Navy crew, this time going aboard frigate HMS Northumberland on a four-month tour of duty with the 220 personnel. Captain Thom Hobbs prepares his ship to set sail, with deputy logistics officer Meghan Burgoyne overseeing the loading of the copious amounts of food required for the time at sea, and young chef Sauhil James prepares for his very first deployment.

While off the coast of Scotland, Northumberland receives intelligence about a Russian submarine that's currently under surveillance and is one of the biggest and most dangerous in the world - and one of the toughest to find and track. New officer recruit Olivia joins for her first taste of life at sea, and while some of the men on board live in cabins with up to 16 people, she is sharing a room with just two others.

HMS Northumberland hunts for a Russian submarine in the Arctic Circle after the vessel disappeares from the ship's radar. While the search continues chef Sauhil is feeling the strain below deck as he helps cook dinner for the crew of 200, but the preparations are interrupted by a serious incident as poisonous fumes seep into the upper deck.

HMS Northumberland is about to leave port when a problem crops up to delay things. Navy Command sends news about an unprecedented gathering of Russian warships and submarines off the coast of Ireland and Northumberland is ordered to investigate. 

HMS Northumberland is deployed off the west coast of Ireland and receives intelligence that a Russian warship has been spotted heading towards Faslane, the home of the British Trident submarine base. There is a concern that if gets too close it could pick up details of some the UK's nuclear secrets.
