Right, but anyway, I find thinking about it fascinating. Take Brazil, for example. (Or Spain or Italy really). You only have one carrier. If you base your naval objectives around it, you better be dammned sure it is protected. You buy all that protection, and still, you are scared to employ the carrier anywhere that it might face danger. When all is said and done, maybe you would have been better with a couple of Ticonderoga cruisers.
Anyway, the Thai carrier makes a lot of sense given the intense need to be able to patrol their waters to protect merchant shipping from Pirates.
What I was surprised about with the Spain Asturias is that it only has one prop. Pretty risky that.
Also, with one carrier, it is necessarily only going to be available about 30-40% of the time with training, maintenance, refits, yard time, etc. That's why we keep twelve, so that any one time we will have five available...and the ability to surge seven or eight total.
A lot to do with politics and national pride for the single carrier nations.
