Ukraine's Black Sea drone campaign (2022-2024)
With no real navy, Ukraine built cheap sea drones and used them to sink or damage Russian warships. The strikes pushed Russia's Black Sea Fleet out of its main base in Sevastopol and reopened a grain export corridor.
Russia pulled major surface ships east and lost freedom of movement in the western Black Sea.
Ukraine proved a land power can contest a sea with drones alone, a template it now reuses.
The Caspian strike is the same playbook, moved to a new sea more than 1,000 miles from Ukraine.
