HMS Bulwark will be doing assaults with Ark Royal and Mounts Bay in the SW, called Ex South West Sabre. The usual set up for an assault ship getting ready for deployments.
You are right, see
here.
Amphibious forces are good intruments for power projection, and can be used in imaginative ways, for example
Bulwark's
deployment to the Gulf last year, or
Ocean's recent deployment to the Carribean. However, we must remember that they are high value assets (much the same as a carrier is), and would need to be defended in a conventional war scenario. We should be very wary of any further cuts to the RN Fleet.
