NUMERS BEHIND BRITAIN’S MOST POWERFUL WARSHIP

The aircraft carrier weighs 65,000 tonnes and has a top speed in excess of 25 knots.

A number of other yards around the country were involved in the build, including Govan and Scotstoun in Glasgow, Appledore in Devon, Cammell Laird in Liverpool, A&P on the Tyne in Newcastle and Portsmouth.

A total of 10,000 people worked on construction of the ship, made up in sections at yards around the UK and transported to Rosyth, where it was assembled.

The ship has a crew of around 700, which will increase to 1,600 when a full complement of F-35B jets and Crowsnest helicopters are embarked.

There is 364,000m of pipes inside the ship and from keel to masthead she measures 56m, four more than Niagara Falls.

Facilities onboard include a chapel, a medical centre and 12-bed ward, staffed with GPS, a nurse and medical assistants, as well as a dentist and dental nurse.

There are also five gyms on the warship which include a cardiovascular suite, two free weight rooms and a boxing gym.

The distribution network on board manages enough energy to power 30,000 kettles or 5,500 family homes.

Its flight deck is 280m long and 70m wide, enough space for three football pitches.

The entire ship’s company of 700 can be served a meal within 90 minutes, or 45 minutes when at

action stations.

The crew is made up of 87 women and 613 men.
