Former prime minister David Cameron has expressed how "immensely proud" he is after HMS Prince Of Wales was declared fully operational.
Mr Cameron invested in the latest aircraft carrier seven years ago while in office.
On Twitter, he said the £3.2bn HMS Prince of Wales becoming fully operational was "a proud moment for the Royal Navy and all our Armed Forces".
The UK now has two aircraft carriers ready for duties with HMS Prince of Wales being declared fully operational and will join her sister HMS Queen Elizabeth for duties around the globe.
The Royal Navy flagship HMS Queen Elizabeth is currently on the second half of her maiden deployment leading the Carrier Strike Group 21 (CSG21) in the Pacific.
