Ughhh . . . yeah that was me some years ago. If we're really looking for non-canonical carriers, I kind of like the 850 meter Polaris-class Carrier that shows up in the Prophecy development material. The specs for that ship just feel right for the immediate post-WC2/3 era, especially with the ship's focus on ion weaponry, a type featured on the Midway-class, and its 250-ship fighter wing. It's a great mid-point between an older Concordia-class and a new Vesuvius-class. In my own head canon, I see these ships as being state of the art in 2668-9, with a few completing construction after the war. Then, by 2671, whatever were left on the slips were canceled and broken up as scrap due to the post-war funding situation. During their late-war heyday, I could easily see a Polaris give a Bhantkara a run for its money!
There's also the 1200 meter heavy carrier that show in one of the early drafts of Victory Streak, but I'm glad that didn't make it to print. This ship is something like 35,000 tonnes, which seems far too light for a ship of its size when measured up against every other carrier except the Armada Lexington.
I kind of envision a post-war navy looking something like this in 2680: 1 Midway-class CVX with 9 more under construction, 4-5 Vesuvius-class CVs, 10 other heavy CVs (Concordias, Lexingtons, Polaris?), 20 Light CVs (Eagle-class), 200 or so cruisers with fighter wings, and 1000 destroyers with fighter squadrons. But again, that's just in my head.
No worries, we all have our own head cannon which can be useful to fill in the blanks on certain items that haven't been given detail in the franchise. Those notes that you posted in combination with Capi's RPG Sourcebook proved useful a few years back when I was briefly toying with bringing back Against all odds. Sylvester, and I had a good test battle going at one point. Sadly though the forum that was hosting it got nuked when Zetaboards merged with Tapatalk.
