HMS Queen Elizabeth is the lead ship of the Queen Elizabeth-class of supercarrier, the largest warship ever built for the Royal Navy of the United Kingdom and capable of carrying up to 40 aircraft. The ship, named for Queen Elizabeth I in a July 2014 naming ceremony by Queen Elizabeth II, began sea trials in June 2017 and will formally be commissioned in December 2017. Her first Commanding Officer is Commodore Jerry Kyd, who had previously commanded the carriers HMS Ark Royal and HMS Illustrious. As Captain of HMS Queen Elizabeth, Kyd will wear the Royal Navy rank of Captain while retaining the substantive rank of Commodore.
HMS Queen Elizabeth has no catapults or arrestor wires and is instead 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 troop transports up to Chinook size and larger. She is the second Royal Navy vessel to bear the name Queen Elizabeth and is to be based at HMNB Portsmouth.
