Looks like the USMC will be visiting at some point this year:
This year we will be operating F-35s, V-22 Ospreys, drones and the RN Merlin helicopters – pushing the boundaries of naval aviation and UK Carrier Strike capability as we progress towards a global deployment in 2025.
(...)Once the ship has completed her propulsion trials, she will bring her flight deck back to life before returning to Portsmouth to prepare for her autumn deployment to the USA.
