The one at the back is HMS Illustrious or HMS Ark Royal. With Invincible being moth balled as we can no longer afford to keep these vessels afloat... Still, at least we're spending our money on worthwhile social engineering projects instead [I can just imaging (insert any moderator name) saying "shut it").
I would say as this was most likely a Gulf operation between the Royal Navy and our 'allies'. Due to the length of the ski ramp I would say it is most likely the Ark.
The front vessel, I don't know.
