Thanks for your comments, As for the size of the ship, this would be alot more desirable to send something like this in littoral waters then a full carrier. Also i was not sure the size of the wing so yes maybe if I remove the helo I can fit the UAV in also the lift is centre behind the Superstructure as that is set off centre to starboard.
For Littoral ops a helo is going to be worth a lot more than the additional UAV that would replace it.
A general rule of thumb is that you can get a single embarked aircraft for every 1000-2000 tons of displacement. This ship can't be more than 6000 tons or so, hence a wing of 5-7 aircraft is the probable level.
