How should Ukraine rebuild its navy after the war?
Short answerBuild for sea denial around the coastline retained: submarines, uncrewed systems, small attack craft, light amphibious capacity, and a strong reserve model.
NotesUkraine's future navy depends first on the territory and coastline it retains, especially access around Odesa. For a defensible Black Sea frontage, the proposed sea-denial force centers on submarines, UAVs and UUVs, fast attack craft, and light amphibious assets rather than a blue-water fleet. Finnish and Swedish influence could also encourage a small regular core backed by extensive national-service reserves. An aside distinguishes the labour pools needed by field forces and defence industry: armed services can train more general recruits, while industrial expansion relies heavily on technical-school and university graduates. Mobilization and production therefore do not draw from an identical population, even when both compete for scarce people.
