A total of 30 Nato ambassadors, along with the deputy supreme allied commander of Europe, General Tim Radford, visited HMS Queen Elizabeth.
The delegation of diplomats, from across Italy, the Netherlands, UK and US, were welcomed onto the 65,000-tonne behemoth by defence procurement minister, Jeremy Quin.
The VIPs were given an exclusive tour of the warship’s four-acre flight deck, with visitors watching as some of the British and American F-35B stealth jets launched from the carrier.
The visit was one of the last diplomatic events on Queen Elizabeth’s schedule, as she continues with the final leg of her journey back home to Portsmouth.
HMS Queen Elizabeth has been spearheading the UK’s carrier strike group on a seven-month mission to the Far East and back, called CSG21.
Mr Quin, who is in charge of buying Britain’s military hardware, said: ’CSG21 has opened the next chapter of the UK’s contribution to Nato
‘The deployment has underlined the breadth, depth and reach of the defence and security partnerships at the heart of the world’s longest enduring alliance.’
Queen Elizabeth set off on her maiden voyage from Portsmouth in May.
Since then, she has travelled more than 40,000 nautical miles to the Indo-Pacific and back.
Ships and aircraft from the carrier strike group – Europe’s most powerful naval fleet – have operated and exercised with more than 40 countries.
This week the aircraft carrier welcomed F-35s from Italy onto the ship – the first time jets from three nations had been embarked on the Royal Navy flagship at the same time.
Dame Sarah MacIntosh, the UK’s permanent representative to Nato, was part of the visit to the carrier. She said: ‘t has been an honour to visit carrier strike group 21 with Nato ambassadors, as HMS Queen Elizabeth returns home.
‘The carrier strike group is allied by design, and has engaged with over 40 allies and partners across the world during this deployment.
‘We are delighted to have demonstrated alliance unity in operation.’
