Supercarrier HMS Queen Elizabeth started moving early in the afternoon and was out of Rosyth Dockyard by the evening, she will soon sail for sea trials.
The vessel will now anchor in the Firth of Forth and sail under the bridges in the hours before midnight tonight.
The operation to move the vessel out of the basin was performed by a fleet of tugs and attracted significant public interest.
The sea trials will monitor speed, manoeuvrability, power and propulsion as well as undertaking weapons trials and additional tests on her levels of readiness.
Following this initial period, HMS Queen Elizabeth will return to Rosyth for further testing and maintenance before heading back to sea for a second stage which aims to test her Mission Systems. She will transit to her home port of Portsmouth Naval Base to be handed over to the Royal Navy later this year.
Defence Secretary Sir Michael Fallon said:
“This is a historic moment for the UK as our new aircraft carrier takes to sea for the very first time. This floating fortress is by far the most powerful ship ever built in Britain that will enable us to tackle multiple and changing threats across the globe.
HMS Queen Elizabeth is an enduring example of British imagination, ingenuity, invention that will help keep us safe for decades to come. She is built by the best, crewed by the best and will deliver for Britain.
For the next fifty years she will deploy around the world, demonstrating British power and our commitment to confronting the emerging challenges from a dangerous world. The whole country can be proud of this national achievement.”
Admiral Sir Philip Jones First Sea Lord and Chief of Naval Staff said:
“This is a hugely significant moment for the Royal Navy, for all our Armed Forces and for our island nation. Once in service HMS Queen Elizabeth will be the largest aircraft carrier in the world outside the United States, and the first designed from the outset to operate a fifth generation aircraft.
Already this ship represents the best of the UK’s industrial and engineering expertise, and once in service she will symbolise our military power and authority in the world for decades to come. There is still much work to do between now and then, but be in no doubt: a new era of British maritime power is about to begin.”

The carrier will now conduct a series of trials as she is put through her paces on the journey to become an operational warship.
The Queen Elizabeth Class aircraft carriers will be the largest surface warships ever constructed for the Royal Navy and will represent a significant increase in capability. The vessels will be utilised by all three branches of the UK Armed Forces and will provide eight acres of sovereign territory. Both ships will be versatile enough to be used for operations ranging from high intensity conflict to providing humanitarian aid and disaster relief.
The class will have increased survivability as a result of the separation and distribution of power generation machinery throughout each ship. The class has been designed with twin islands, which separates the running of the ship from the flying operations resulting in greater visibility of flying operations.
Instead of a traditional single island, the has two smaller islands. The forward island is for ship control functions and the aft (FLYCO) island is for flying control.
The reason for two bridges is, simply put, due to the gas turbine exhausts. The design would have either had two small islands or one large, long island. The two smaller islands were chosen. The location and alignment of the islands are based around the 2.4 metre diameter gas turbine exhausts which were pre-fitted in the island and below in the ship superstructure.
Advantages of the two island configuration are primarily increased flight deck area and reduced air turbulence. Flight control in the aft island is positioned perfectly for aircraft approaches and deck landings.
Surprisingly for their sheer scale, each ship will only have a total crew of 679, only increasing to the full complement of 1,600 when the air elements are embarked. This is made possible by extensive automation of many systems.
Queen Elizabeth is due to be handed over to the RN in 2017.
She’ll begin flying training with helicopters later this year and this will be followed by F-35B jets from 2018.
