Can these ships operate VSTOL aircraft?
Probably not. The only country making them is the U.S. with the F-35B and the deck would need to be built out to handle the heat and stress. I doubt it was.
On the other hand, they *can* operate some pretty nasty Russian helicopter gunships from them... and since Egypt got the amphibious assault carriers that Russia was going to put their Ka-52K scout/gunships on, Russia has sold Egypt the Ka-52Ks that Russia was going to put on the Mistrals. An additional 46 or so Ka-52 land-based variants have been ordered to go along with them.
