WEBF... "The sky is falling" scare-tactic headlines and grandstanding by officers who should know better aside, the reality is that the RN has the situation well in hand.
The reality is that there are currently RN personnel assigned to the various flight deck divisions on some USN carriers, others attending the LSO (Landing Signals Officer) school in the US, and the USN is working with the RN (currently in the early stages) to establish a full training program for the RN's flight deck crewmen.
By the time PoW is ready to land her first aircraft (F-35C, T-45C, or whatever) there will be a fully trained flight deck crew of RN sailors aboard... most of whom will have spent at least a little time aboard a USN CVN flight deck, working beside the American flight deck crew.
