There are only few countries in the world that really have a use of an aircraft carriers at all. As for the rest, it is totally needless and it's nothing but trying to compensate for their other short comings. Really, what is Turkey going to do with an aircraft carrier that may only ever carry helicopters and one or two F-35's, since the whole F-35 project is not a certainty to produce the aircraft numbers it wanted to produce as more countries are reducing their orders due to astronomical cost per aircraft. Even if Turkey did pay and receive 100 F-35s she put in an order for, just how many F-35s would she dare to put on an aircraft carrier which will become the major target for Turkeys enemies in a war. This carrier would also need several support ships to sail with her.
Aircraft carriers are used to protect lands belonging to countries far away from home. What major land does Turkey have far away from home that she needs an aircraft carrier to protect? I can't think of any. The other purpose of an aircraft carriers to be used in wars far away from home. Turkey cannot even dare to pick a war with her immediate neighbours, let alone pick a war in far distances away from home. Overall, it is money down the drain for Turkey building this carrier for $3 Billion USD. This money can be best spent to give the TCs in the north a totally free healthcare system, specially if they can't get one in the RoC any longer.
