[Yo-Yo]

No angled flight deck? I wonder why.

An angled flight deck is for arrested landings of conventional takeoff and landing aircraft. This ship will use the F-35B short takeoff/vertical landing aircraft.

The F-35B will take off without a catapult by using a short rolling takeoff off of the bow ski jump, and land vertically on one of those white checkmark spots.

The carrier was designed to have an angled deck if for any reason the Royal Navy decided to go with a catapult takeoff/arrested landing (CATOBAR) aircraft. For the angled deck, pretty much all you have to do is repaint the lines. (And add the arrestor gear, and the catapults, and...)

Here is a pic of the CVF in both forms:

The 'impact' area of the deck will need to be strengthened, and there will need to be extensions aft and port forward (visible in the comparison pics you posted).

The catapults will be ... interesting. I'm assuming that they wouldn't go with steam, because that would require major plumbing changes PLUS a source for steam (since the ships will be gas-turbine powered). That leaves hydraulic or, more likely, electro-magnetic of the variety being put into CVN-78. Electro-magnetic catapults will require LOTS of additional electric power, however. I'm assuming that the ships are designed to be upgraded for the extra required capacity ...

That will be interesting. The Harrier has nozzles that can rotate to angle with the ramp whereas the F-35 Aft nozzle rotates to a straight down position and the lift fan blows directly down. Not sure if this makes a difference but the F-35 shouldn’t need a ramp.
