Timeline of 2022 Ukraine Invasion: War In The Black Sea
Reflecting on the first year of the war, I am putting together a timeline of the most relevant events in the Black Sea. This will not be exhaustive, but should provide a useful overview. Hopefully this will be of benefit to those interested in studying the war at a later date.
If I have missed anything significant please let me know. The usual caveats apply
Build -up phase
Jan-Feb 2022: Russia builds up a force in the Mediterranean. Under Russian doctrine this is to counter the NATO presence there and deter intervention.
Jan: Russia transports several Raptor assault boats from Baltic fleet to Black Sea via road. Candid video shared Jan 30.
Feb 8-9: Six Russian warships enter the Black Sea as part of build up, transiting the Bosporus. Mainly landing ships and an Improved KILO class submarine.

Feb 15: Russia deploys Tu-22M3 BACKFIRE-C bombers and MiG-31K FOXHOUND fighter jets to Khmeimim in Syria. These are to threaten NATO warships in the Mediterranean. Russia reports that the Kinzhal hypersonic missile carried by the Mig-31K can attack aircraft carriers. The Tu-22M3s are observed with legacy AS-4 KITCHEN missiles.
Feb: Russian Navy moves trained dolphin pens deployed to Sevastopol harbour entrance.
Early Invasion - The 3 Day War
Feb 24: Invasion begins.
Feb 24. Russian Navy captures strategic island of Snake Island. The SLAVA Class cruiser Moskva plays a prominent role. Reputedly, the Ukrainian garrison replies to suggestions to surrender with “Russian Warship, go ?!?% yourself”.
Feb 24: Russia declares a prohibition on navigation in the North-Western part of the Black Sea. Defined area down to the parallel 45-21 N, and from 0400 hours on 24 February 2022. Several third-country merchant ships were subsequently attacked, attributed to Russia. This blockade is total.
Late Feb: Anti-invasion naval mines laid off northern Black Sea coast, likely by Ukraine. Possibly some by Russia.
Feb 28: Bosporus closed to naval traffic. This prevents Russia transferring any of the remaining warships in the Mediterranean to the Black Sea. Russia had plans to send one, possibly two, more SLAVA class cruisers to Black Sea.
Before March 3: Majority of Ukrainian Navy warships, captured, sunk or scuttled at onset of invasion. Notably, the scuttled vessels include the frigate Hetman Sahaidachny. Ukraine, whose fleet was massively out-gunned, is left with only a few smaller vessels.
Feb-Mar: Russian Navy warships bombard Ukrainian coastline off Odesa.
Feb-Mar: Russia performs multiple amphibious demonstrations where landing ships, supported by minesweepers and other warships, threaten amphibious landings near Odesa. The landings were considered a serious threat but ultimately never come.
Mar 1: Belarusian president Alexander Lukashenko revealed plans for an amphibious landing near Odesa in a televised security council meeting. The landings did not materialize.
Mar 7: Reports that Ukraine hit and sunk a Russian patrol ship, Vasily Bykov, with rocket fire off Odesa. These reports subsequently shown to be incorrect, the first of several ‘wishful sinkings’.
Mid-Mar: Russia starts removing the hull numbers from its warships in the Black Sea to frustrate attempts to gather intelligence on movements. This can be viewed as a sensible precaution taken late.
March: Subsequent reports that the Russian frigate Admiral Essen was hit by a Neptune missile off Odesa. There were several 'wishful sinkings' at the time, however indications are that this occured. Missile did not hit cleanly, limited damage.
Mar 22: Russian Raptor class assault boat hit by Ukrainian anti-tank missile near Mariupol.
Mar 24: Russian Navy Alligator class landing ship Saratov hit while unloading at Berdyansk on Sea of Azov. Possibly hit by a Ukrainian ballistic missile. The ship explodes, damaging two Ropucha class landing ships which manage to escape. The ship sinks at the quay. Russia stops using the port for reinforcements.

Apr 7: Reported in Naval News that SLAVA class cruiser Moskva is operating predictably. Precursor of things to come.
Apr 13. The SLAVA class cruiser Moskva, the flagship of the Black Sea Fleet and most powerful warship in the area, is hit by two Ukrainian Neptune anti-ship missiles. It sinks the next day.

Post Moskva Sinking
Apr 21: “Sapphire” Ukrainian search and rescue vessel was returned to Ukraine following its capture on Feb 26, as part of the first prisoner of war exchange.
May: Fighting intensifies around Snake Island. Ukrainian TB2 drones play a major role, hitting two Raptor assault boats and sinking a landing craft at the jetty. Russian attempts to reinforce and supply it begin to appear more precarious. On at least one occassion Ukraine deploys a BM-27 Uragan MLRS on a barge to bombard the island.
May 6: incorrect reports that Admiral Makarov was hit by missiles off Odesa. Subsequently not supported by evidence.
May: Russia takes at least one captured Ukrainian Navy Gyurza-M gunboat into operational service. It was one of several captured vessels transferred from Sea of Azov to Novorossiysk than month.
Late May: Harpoon and Brimstone missiles supplied to Ukraine. These threaten Russian Navy warships.
Late May: Smaller Russian warships, including gunboats, involved in capture of Mariupol.
Jun 10: Ukrainian Navy landing ship Yuri Olefirenko attacked by Russian rockets near Ochakiv. The ship, the largest remaining in the Ukrainian Navy, survives.
Jun 17: Russian ship Vasiliy Bekh, carrying a SA-15 GAUNTLET (Tor) air-defense missile system, is sunk by Harpoon or Neptune missiles.
Jun 20: Ukraine attacks Russian controlled gas platforms in mid-Black Sea with Harpoon or Neptune missiles. One platform still burning as-of Feb 2023.
Jun 29: Two target barges, normally resident in the Russian naval base at Novorossiysk, were towed to Kerch. They are positioned as decoys to protect the bridge from attack.
Jun 30: Russia abandons Snake Island.
Jul: Threatened by Harpoon and Neptune, Russian ships largely withdraw from western side of northern Black Sea. This is a significant change in the balance.
Jul 7: Ukrainian forces briefly land on Snake Island. Special Forces from 73rd Naval Special Purpose Center used underwater vehicles in this mission.
Jul 27: Black Sea Grain Initiative (BSGI) agreed, effectively breaking the blockage of Odesa.

Several USVs penetrate the harbour and two warships, the minesweeper Ivan Golubets and frigate Admiral Makarov, are hit by 'Mykola' USVs. Neither ship is sunk. However Russia withdraws fleet into bases and starts initiating increased defenses.

Feb 10: Russia deploys its own explosive USVs, with one targeting the bridge at Zatoka, south of Odesa.
Feb 28: Ukrainian UAV attack on oil facilities at port of Tuapse, north of Sochi. This is notable for its distance from Ukrainian controlled territory and strategic relevance. Russia deploys air defenses there, observed Mar 6.
