The HMS Ocean is far more than just a ship.
The Royal Navy vessel is home to a vast community, carrying 1000 passengers with shops, a bank, gyms, pubs and even its own police force on board.
One officer labels it “a village that makes war”.
Channel 4’s new documentary series Warship takes viewers right into the heart of the 21,000 tonne boat.
Warship spans a seven-month deployment to the Middle East, from the moment the Ocean leaves the harbour in Plymouth.
The documentary follows the day-to-day running of the HMS Ocean, as well as offering insights into the history of the 20 year-old boat.
There’s also a look into the staff who contribute to the upkeep of the ship, from old hands to new recruits on their first voyage.
Interestingly the future of the HMS Ocean is in question – while it’s the flagship of the Royal Navy fleet, the boat is due to be decommissioned after two decades of service.
It’s said to be up for sale with foreign governments showing interest in obtaining it – and they won’t get much better insight into its running than this three-part series.
