Description
The United Kingdom Carrier Strike Group 21 (CSG21) is a British-led naval force currently deployed on Operation Fortis since May 2021. The Carrier Strike Group is seen as the beginning of the British Government's tilt towards the Indo-Pacific region in terms of defence and foreign policy, that had been announced in March through the Integrated Review. It is the first strike group deployment for the Queen Elizabeth-class aircraft carriers, and the first operational deployment of the UK Carrier Strike Group since 2011. The deployment is the largest single deployment of F-35 fighter aircraft since the programme started in 2006, and the largest fifth-generation fighter carrier air wing in the world. Furthermore, HMS Queen Elizabeth sees the largest number of personnel embarked since she entered service, and the group will contain the largest number of Royal Navy maritime helicopters deployed in over 10 years.
