Work continues on HMS Prince of Wales, the second Elizabeth class carrier, who was officially named in September 2016. Along with her sister ship HMS Queen Elizabeth, this is the largest engineering project ever undertaken by the UK's military, costing over £6 billion. Queen Elizabeth was the first aircraft carrier to be built in the programme and set sail from Rosyth last summer.

HMS Prince of Wales is set to follow in 2019 and those working on the 280-metre carrier say lessons have been learned in the construction of the first ship, which will make the second "more efficient". The pair are Queen Elizabeth-class aircraft carriers and are being built by the Aircraft Carrier Alliance (ACA), a partnership of BAE Systems, Babcock, Thales and the Ministry of Defence.

Overall, six shipyards around the UK - Appledore, Birkenhead, Govan, Portsmouth, Rosyth and Tyne - have been involved in building various parts of the carriers. Those behind the project, which costs an estimated £6.2 billion overall, say the QE Class will be the centrepiece of Britain's naval capability, with an aircraft carrier permanently available to be deployed anywhere in the world in military or humanitarian action. The first seagoing captain of the Royal Navy's second brand new aircraft carrier will be Stephen Moorhouse. Captain Moorhouse is an experienced naval officer, having worked as Commanding Officer on HMS Ocean and HMS Lancaster. Captain Ian Groom, who is currently serving as the Senior Naval Officer on board HMS Prince of Wales, will be handing over to Moorhouse next year.
