When Queen Elizabeth embarks on its first deployment in 2021, its airwing will include a mix of U.S. Marine Corps and Royal Navy F-35B fighters, as well as a support team comprised of U.S. Navy aviation ordnance personnel from the Nimitz-class aircraft carrier USS John C. Stennis (CVN 74), a communications specialist from Norfolk's Navy Computer and Telecommunications Master Station Atlantic, and a Personnel Exchange Program (PEP) officer attached to the UK CSG staff as a Strike Warfare Plans Officer. The Arleigh-Burke destroyer USS The Sullivans (DDG 68) is also scheduled to deploy to support the UK’s CSG.
