Queen Elizabeth-class aircraft carrier

The Queen Elizabeth-class aircraft carriers of the United Kingdom's Royal Navy consists of two vessels. The lead ship of her class, HMS Queen Elizabeth, was named on 4 July 2014 in honour of Elizabeth I and was commissioned on 7 December 2017. Her sister ship, HMS Prince of Wales, was launched on 21 December 2017, and was commissioned on 10 December 2019. They form the central components of the UK Carrier Strike Group. The contract for the vessels was announced in July 2007, ending several years of delay over cost issues and British naval shipbuilding restructuring. The contracts were signed one year later on 3 July 2008, with the Aircraft Carrier Alliance, a partnership formed with Babcock International, Thales Group, A&P Group, the UK Ministry of Defence and BAE Systems.
