Angled deck or not....?
I'm just a crab onlooker in the carrier/Dave ? saga (although I am pro carrier), however.
This link seems to imply that when it was intended as a conventional carrier it had an angled deck:

But once we went STOVL it would appear the angled deck disappeared, see about 4 photos down (note the date):

But then again, both of these are from open sources which have a history of getting things wrong!
