Warship: Life at Sea - Episode Guide

Heading out to the Med and the Black Sea, the 280 men and women onboard face a heart attack, a man overboard, and a show of force from Russian airplanes.

The ship and its crew are deep in the heart of the Black Sea, heading towards Crimea, when a Russian ship HMS Duncan has been tracking suddenly disappears. The crew discover that the Russians are also tracking them and the situation soon escalates.

The mood on Duncan changes with the news that a chemical weapon is reported to have been used in Salisbury. When a second chemical attack takes place, this time in Syria, the ship goes to action stations for the very first time.

The crew stand-off with a Russian warship over Syria, and young sailor Danny tries for his first promotion, but chef Liam gets in trouble for drinking and might lose shore leave privileges.

Cameras focus on a female lieutenant training to become a captain. Then, upon entering the Mediterranean, there's an emergency when a crew member falls overboard into choppy waters. A desperate search begins to find him.

The crew must defend French aircraft carriers off the coast of Syria, and help evacuate Britains being held in Cyprus.

The crew have been sent to Ukraine, but the unexpected absence of Russian ships leaves everyone unsettled.

As Iranian forces take control of the British-flagged oil tanker Stena Impero and hold the crew hostage, HMS Duncan is ordered to the Persian Gulf. The captain is briefed by the captain of the Montrose - another Royal Navy ship in the region - who comes on board for a private intelligence update on Iran. After arriving in the Gulf, the Duncan escorts a tanker through the Strait of Hormuz, while Iranian forces immediately make a move and try to capture another ship, resulting in a tense stand-off.

HMS Duncan and her crew face increasing pressure in the Strait of Hormuz as Iran steps up its efforts to capture a second British tanker. Three weeks into Duncan's mission, Iran is still holding the Stena Impero captive, but international pressure is mounting against them. The ship is ordered to hold the line and continue escorting fuel tankers safely through the Strait, while awaiting relief by HMS Kent. When a fire breaks out in the engine room, it threatens the ship and the lives of some of the crew.

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.
