HMS Queen Elizabeth is the lead ship of the of aircraft carriers built for the Royal Navy. Capable of carrying 60 aircraft including fixed wing, rotary wing and autonomous vehicles, she is named in honour of the first , a World War I era super-dreadnought, which in turn was named after Queen Elizabeth I. The carrier Queen Elizabeth carries her namesake ship's honours, as well as her Tudor rose-adorned crest and motto.

Queen Elizabeth commenced her sea trials in June 2017, was commissioned on 7 December 2017 and entered service in 2020. Her first seagoing commanding officer was Commodore Jerry Kyd who was appointed in 2014 but did not take command until May 2016, having previously commanded the carriers and . , her commander is Claire Thompson.

The ship is designed to operate V/STOL aircraft. The air wing will typically consist of F-35B Lightning II multirole fighters and Merlin helicopters for airborne early warning and anti-submarine warfare. The design emphasises flexibility, with accommodation for 250 Royal Marines and the ability to support them with attack helicopters and large troop transports such as Chinooks. She is based at HMNB Portsmouth.

Queen Elizabeth will deploy as the central part of a UK Carrier Strike Group with escorts and support ships in order to deliver carrier-enabled power projection.

Design and construction On 25 July 2007 Defence Secretary Des Browne announced the order for two new carriers. At the time of approval the first carrier was expected to enter service in July 2015 and the budget was £4.085 billion for two ships. The financial crisis led to a political decision in December 2008 to slow production, delaying Queen Elizabeth until May 2016. This added £1.56 billion to the cost. By March 2010 the budget was estimated at £5.9 billion and in November 2013 the contract was renegotiated with a budget of £6.2 billion. The in-service date was further extended to 2020 in the Strategic Defence and Security Review in October 2010.

Construction of Queen Elizabeth began in 2009. The assembly took place in the Firth of Forth at Rosyth Dockyard from nine blocks built in six UK shipyards: BAE Systems Surface Ships in Glasgow, Babcock at Appledore, Babcock at Rosyth, A&P Tyne in Hebburn, BAE at Portsmouth and Cammell Laird (flight decks) at Birkenhead. Two of the lower main blocks, together weighing more than 6,000 tonnes and forming part of the base of the ship, were assembled and joined into one piece on 30 June 2011.

On 16 August 2011, the 8,000-tonne Lower Block 03 of Queen Elizabeth left BAE Systems Surface Ships' Govan shipyard in Glasgow on a large ocean-going barge. After travelling around the northern coast of Scotland, the block arrived at Rosyth on the evening of 20 August 2011.

On 28 October 2012, an 11,000-tonne section of the carrier began a lengthy journey around the south coast of England, avoiding bad weather, from the shipbuilding hall at Govan to the Rosyth dockyard; it arrived on 21 November. The forward island was constructed at BAE Portsmouth and attached on 14 March 2013; the aft island was attached in June 2013. The ski jump was added in November 2013, leaving just the lifts and radar to be lifted into place. By September 2013 Queen Elizabeth was 80% complete internally.

The carrier is three times the size of the Invincible-class, and has the ability to carry approximately three times as many aircraft. Despite this, Queen Elizabeth has marginally fewer crew than the Invincible-class. The ship has two superstructures, or islands, one for navigation and ship's operations and the other for flight control and aerial operations. The islands can take on each other's function if one is incapacitated.

Naming ceremony

Queen Elizabeth was christened at Rosyth on 4 July 2014, by Queen Elizabeth II, who said that the warship "marks a new phase in our naval history". Instead of smashing the traditional bottle of champagne on the hull, she used a bottle of whisky from the Bowmore distillery on Islay.

The ceremony was attended by Prince Philip, Duke of Edinburgh (the Lord High Admiral), Admiral George Zambellas (First Sea Lord), senior naval officers from the United States and France, and by politicians including David Cameron and Gordon Brown (the Prime Minister and his immediate predecessor) and Alex Salmond (the First Minister of Scotland). The official piece of music HMS Queen Elizabeth March, composed by WO2 Bandmaster John Morrish, was performed at the naming ceremony by the Band of HM Royal Marines Scotland. This piece of music is a competition-winning march chosen by the Carrier Alliance Group, performed and recorded by the Royal Marines Massed Bands.

The ceremony also featured a fly-past by the Red Arrows and a second comprising Royal Navy, Royal Air Force and British Army helicopters. was berthed adjacent to Queen Elizabeth during the ceremony.

The ship was floated out of dry dock on the morning of 17 July 2014. Fitting out was completed at the end of 2015 and the crew moved aboard in May 2016.

Sea trials

Sea trials were planned beginning in March 2017 with delivery expected in May 2017, but technical issues delayed her trials. Prior to her departure from Rosyth, an extensive survey was carried out of the Firth of Forth by and 42 Regiment, Royal Engineers to gather information on the tides, the depth of the river bed, and the height of the three river crossings (Forth Bridge, Forth Road Bridge, and Queensferry Crossing). This was necessary as the most recent data available were 60 years old.

Queen Elizabeth sailed on 26 June 2017 to undergo sea trials. The first stage of the operation was to move the ship from inside the fitting out basin, via one of the access gates, into the Firth of Forth itself, before taking her under the three Forth bridge crossings. Once this was accomplished, the ship took to the open sea off the east coast of Scotland to undertake the first set of trials, including handling and speed tests. During this period, Queen Elizabeth was accompanied by a pair of Type 23 frigates, and , acting as escorts. The first aircraft to land on the ship was a Merlin HM.2 helicopter of 820 Naval Air Squadron on 3 July. Queen Elizabeth arrived at her first stopover at Invergordon, where the ship was fuelled and provisioned. At this point inspections of the hull were carried out. This opportunity allowed defect rectification to be carried out prior to the ship returning to sea.

On 8 August 2017, Queen Elizabeth diverted from her sea trials to rendezvous with the ships engaged in Exercise 'Saxon Warrior'; this allowed for a photo exercise in company with the American and her Carrier Strike Group (CSG), comprising , , , and HNoMS Helge Ingstad.

Queen Elizabeth was scheduled to return to Rosyth at the end of July for rectification work based on the results of the ship's first sea trials, before putting to sea for a second time to undergo a series of mission system tests, prior to being handed over to the Royal Navy. This plan was abandoned and she instead steered for her home port, Portsmouth.

Queen Elizabeth arrived at HMNB Portsmouth for the first time on 16 August 2017 and berthed at the newly renamed Princess Royal Jetty (formerly Middle Slip Jetty).

On 30 October 2017, the ship departed Portsmouth for the first time for the second phase of her sea trials off the south and south-west coasts of England. For part of this second period of sea trials, she was accompanied by the Type 45 destroyer . Queen Elizabeth returned to Portsmouth on 21 November 2017 to prepare for her official commissioning ceremony, which was held on 7 December 2017. Following the ship's commissioning, she underwent a period of defect correction in Portsmouth; one instance was a leak through a seal in one of the propeller shafts, which the Royal Navy stated was not serious enough to keep Queen Elizabeth from her planned programme.

Operational history On 2 February 2018, Queen Elizabeth sailed from Portsmouth for a second time, for a six-week deployment to undergo the first phases of operational training; initially, the ship was scheduled to head into the Western Approaches to undertake her initial Operational Sea Training (OST) programme. Once complete, Queen Elizabeth was then taken into the North Atlantic for both heavy weather testing and operations to begin helicopter certification, including with Merlin Mk2 and Mk3 and Chinook helicopters. During this deployment, the ship made her first overseas port visit, stopping over in Gibraltar from 9 to 12 February. During this, the ship also began initial amphibious assault trials, with Royal Marines from 42 Commando embarked to simulate an air assault scenario. Queen Elizabeth was also scheduled to undergo a first replenishment at sea from ; although the actual replenishment had to be abandoned due to bad weather, the rendezvous allowed both ships the opportunity to simulate the scenario in detail. Queen Elizabeth returned to Portsmouth on 27 February 2018, berthing at Princess Royal Jetty. On 2 March 2018 in Portsmouth Harbour, Queen Elizabeth successfully tested her port side Marine Evacuation System (MES), a series of bright orange inflatable escape chutes and rafts.

Queen Elizabeth departed Portsmouth for a third time on 10 June 2018, heading to the coasts of Cornwall for a second phase of helicopter flight trials. After the trials were completed, Queen Elizabeth headed for home and performed her first replenishment at sea (RAS) refuelling operation with Tidespring on 21 June 2018 in the English Channel, then returned to Portsmouth on 23 June 2018. On return from the initial OST and helicopter certification work, further work was undertaken to prepare the ship for the operation of fixed-wing aircraft, in conjunction with regular maintenance and installation of her final weapons fit.

2018: Westlant 18 Queen Elizabeths first significant deployment took place during autumn 2018, when the ship travelled across the Atlantic to begin flying trials with her fixed-wing aircraft. Although the programme covered a range of areas, including the continued workup of the Commander UK Carrier Strike Group and his staff, embarked for a deployment for the first time, and small-scale exercises to test the ship's ability to land troops in the secondary amphibious role, the primary purpose was the first phase of fixed-wing flying trials involving the F-35B over two separate periods of approximately 3–4 weeks each starting in mid-September, utilising a pair of the instrumented development aircraft from VX-23, the US Navy's air testing unit at NAS Patuxent River. The testing programme saw the first launch of an F-35 from a ski-jump at sea (the F-35B has operated from the US Navy's assault ships, but these are not fitted with ski-jumps), and the first demonstration of the shipborne rolling vertical landing technique.

In addition to the F-35 trials, Queen Elizabeth also began qualifications for types of aircraft operated by the US armed forces, including the V-22 Osprey. As part of the deployment, the ship made her first overseas port visit to New York City in October, in between layovers at Naval Station Norfolk, some operations in the Caribbean possible, to test the ship's hot weather performance, as well as being on hand if needed for any disaster relief operations during the hurricane season. Queen Elizabeth was scheduled to return to the UK in December.
