The loss of Russian dominance in the Black Sea is a major consequence of the Ukraine war.
As successful as this is, like the new drone ware far is effecting the ground wars, sea drones are a new threat to all navies and give capabilities to nations without navies and a lot of money to cause tremendous damage.
Imagine a ship at port, crew on shore pass and a terrorist group gets/ makes one of these and launches it, esp if ship is not at a naval port, but even so are our bases prepared for this kind of threat. Add a few airborne drones say targeting an aircraft on deck or flying into the hanger deck.
Gonna get real interesting very soon IMO
