"Designed to be continuously deployed with minimal maintenance for up to two years and operate for 5000 hours per year"
I can't even imagine what kind of shape she'll be in after two years. Remember that American ship that finally returned to port after 11 months, and how dilapidated and rusted her hull and superstructure were? Doubling that, with "minimal maintenance" and likely minimal crew...yikes.
I'm also a lot bit surprised at how light the armament is for a ship of that size. 16 VLS cells, a 5" gun, eight NSMs, and two RAM launchers for point defense. That and a handful of machine guns. Compared to a Tico, which is a thousand tons lighter, but carries 122 VLS cells, eight Harpoons, two 5" guns, two CWIS, and six torpedo tubes. It's twice the firepower, if you load the 16 VLS on the F126 with quad-packs of SAMs, and almost eight times as much if you're loading full cell shots like cruise missiles, antiship missiles, ASROCs, or others - and the Tico can quad-pack enough ESSMs to turn an entire Air Force into aluminum confetti.
I get the idea of the multirole mission modules, but seriously, you're building a heavy cruiser by WWII's standards and you're only arming it to that level? Something feels left behind pretty dramatically.
