A sea-denial navy for Ukraine

What shape should a future Ukrainian navy take?

It should emphasize conventional submarines and fast attack craft for sea denial rather than trying to match Russia with large surface combatants.

The proposed force is designed around sea denial rather than matching Russia ship for ship. Conventional submarines and fast attack craft could threaten approaches to Odessa and make coastal operations more expensive for the Black Sea Fleet. That naval pressure would free Ukrainian ground forces from maintaining as large a coastal defence commitment. The exact fleet would still depend on the coastline, ports and resources left under Ukrainian control after the war.
