Thanks. I have read the article. I don't see any prohibition on the use of vertical lift aircraft. If you notice the article links the decertification of the arresting gear to the prohibition of landing fixed wing planes. You don't need arresting gear to land Harriers.
"Last week the ship's arresting cable gear was decertified, meaning it can no longer land fixed-wing planes, only helicopters. Two of its four catapults also have been shut down. "
