Both of those countries have unimpeded access to open ocean, two of our three seas have no use for carriers, and the other one is boxed in (as vast as it is) by Gibraltar and Suez. Good luck getting an aircraft carrier out on the ocean if the tide turns and they decide to close the gates on us.
This AC is more of a vanity project than an absolute necessity in my eyes. We barely have overseas presence far away to justify it, and what we have we'd be far better served by having permanent military/naval bases on those countries. Several billions we are going to have to spend to build the carrier, warships to protect it and auxiliaries to support it (on top of planes) would be far better served expanding our warships and submarines or diverting those resources to other branches. Hell, you can probably make Trakya and 2 more like it focused on drones for the price one carrier alone let alone multiple.
And what longer game are you talking about? We aren't even the dominant power in our region, what game necessitates using our limited resources on more than one carrier?
I fully agree with you with respect to the unnecessity of a Carrier for our Navy. More than a vanity project it is probably a political project though.
However, even the study of the project will open our horizons.
2 LHDs,, one of them a UAV carrier, and at least 2 more LSTs would normally suffice for us.
But this political move now is in a way godsend to us. For one thing this aircraft carrier we are talking about, won’t happen before 2040. (Look at the TF2000 example). But come 2030’s and further, both our economical standing should improve and the world sociopolitical outlook will change. To be ready to project force away from our own seas and protect our overseas concerns and assets will come in real handy.
With respect to being locked in to the Mediterranean, I again agree with you. But Italy has the same situation. After 1960, they no longer have any overseas territory. So they too don’t need a carrier. Yet they have a carrier in hand. (Garibaldi was recently decommissioned)
They don’t really need to project power overseas. They definitely don’t need a carrier for Sardinia and Sicily. LHDs would have sufficed.
But they want to be able to keep the expertise of high end ship building alive in the country and be a part of the world community to protect NATO and European assets.
