If DzKK is not prepared to cut up the runway, then the whole project is a non-starter. I can’t see how they intend to land a UAV on such a short runway?
They will (probably) do additions which can be removed later, and i am sure our guys will find solutions to insert those without damaging the coating, or damaging in the limited areas to not affect future possibilities. There are several openings on board sides which can possibly used to install wires and hydraulics.
DzKK plans another ship to specifically focus on AC operations. When it is commissioned Anadolu will return to pure LHD or LHD with STOVL (UAV more likely) to aid in amphibious operations. The second ship likely will have launch and arrest systems mounted since the beginning. And a secondary runway to take off.
So a hydraulic system that can handle light weight planes will have to be designed.
Entire project could be about this actually. A lighter arresting system which can be mounted on deck and occupy less area compared to a large one. since this particularly will be catching small tactical drones. from simple assumption of kinetic energy, a lighter drone-like system would have slower landing speed and lighter mass and probably exert 1/50th (estimating) of the force to be exerted by a fighter.
Also installing a fully fledged arresting system could render stern elevator useless. Moreover the stepped platform on stern and also the elevator (since i don't assume it will be good if an airplane touches down at the elevator while landing) can make landing slightly harder too. Typical aircraft carriers have a smoother runway extending upto the stern.
Also frequency of aircraft operation will probably shrink down:
In proposed solution:
An aircraft touches down and possibly stops around the island, towed to the elevator on fore side, meanwhile another aircraft will be taken out from hangar just after another has touched(for safety it will be kept in hangar just in case), placed on elevator, taken up, and took off.
However in STOVL:
An aircraft is prepped on runway while another takes its landing position on its location, simultaneously one takes off, possibly another follows without waiting the landing of the earlier one.
Also landing spot is off the run way, so the airplane can easily wait for take off to be completed to be towed in hangar.
So proposed solution is only better than nothing, to save the day, if there isn't any further solutions to make TB2 a STOVL.
A picture clearly shows what i mean about the stern elevator.
