The parts of the angled deck which appear to have been dropped from the design can be restored without any difficulty as they are only external steel structure. I suspect they were dropped to appease the politicians by saying "Look, we've cut big chunks off the ship, think how much money we've saved!" when in fact all they have cut is a few thousand tonnes of relatively cheap steel which can easily be put back later. The overhang is as large as it was before, it's just the small forward extension and aft round down that have been axed and they were just steel with no 'moving parts' anyway. None of the RN's previous eight angled deck carriers were built with angled decks and they coped very well with the additions. The US Essex and Midway classes were built as axial deck ships and also took to the angled deck very well, and they were all designed before the angled deck or steam catapult were even concieved. CVF has been designed with these modifications in mind so retrofitting them will not be nearly so difficult or expensive.
