The Queen has arrived at Rosyth Dockyard in Scotland to formally name the largest ship ever built for the Royal Navy.
The ceremony marks the completion of the 65,000 tonne aircraft carrier after five years of construction work which took place at six different shipyards across the UK.
To honour the warship's birthplace in Scotland Her Majesty will smash a bottle of Islay whisky, from the first distillery she visited, against the bow.
Staff from BAE in Portsmouth who helped to make parts of HMS Queen Elizabeth have been watching the naming ceremony on a big screen in the city.

Royal Navy helicopter carrier HMS Illustrious has just paid a routine visit to Lisbon after completing Exercise Deep Blue.
Exercise Deep Blue was an Anti-Submarine Warfare exercise involving surface, submarine and air participants from the UK, France and the Netherlands.
For an intensive two week period, a multitude of exercise scenarios tested, and proved, the capabilities of all units working together as a multi-national task group.
Crews were able to enjoy the fantastic sights and sounds of Lisbon after their busy work schedule!
HMS Illustrious has been awarded a commendation for their efforts supporting the humanitarian and disaster relief operation following Typhoon Haiyan in the Philippines.
A team of 21 officers and ratings from the ship's supply department were recognised by Fleet Commander Vice Admiral Philip Jones in Portsmouth Naval Base.
HMS Illustrious was part of a deployment to the Middle East – when she was diverted to assist in the Philippines in November last year.
The citation reads: “ There is no doubt that the supply chain department made an exceptional and outstanding contribution. Largely unseen, the team displayed the highest levels of professionalism and were absolutely pivotal to HMS Illustrious’ ability to relieve suffering in the Philippines."
