There are a shit load of heli platforms and pseudo VSTOL acreage swimming into the HW.
The great big wild card will be the UK mega heli carriers. Based out of the gulf these are ideal for trouble making in the western HW region.
I always reconned that they would be NATO staffed but there is a goodly chance that they might have maritime mercs under the flag. Looked at as nothing more than a great big mobile air base these things could be rented out to expeditionary forces in the immediate area for selected commercial operations. I don't mean sovereign forces either. This is the age of John Company again.
Whatever trouble is planned the area around the UK will not need a RN presence. The kill zone is to be far, far away.
