Modern navies need more proven hulls before exotic new types

Which new warship concept is most worth building: a ground-effect craft, stealth carrier, or arsenal ship?

None is the first priority; most navies need more of their existing ships, followed by useful uncrewed or support variants.

Ground-effect craft, stealth carriers, and arsenal ships all attract attention, but none solves the immediate shortage of hulls. Novel labels can create fresh research, training, funding, and integration burdens before they add usable capacity. More examples of proven designs would give navies ships they already know how to crew and support. Uncrewed derivatives and support-oriented sloops are plausible additions once the basic force has sufficient numbers. Novelty is a poor procurement priority while established fleets remain too small.
