Preliminary analysis of the vessels suggests 3 groups. Two are made up of combatants, and one has several landing ships. The landing ships appear to have sailed directly from their staging position off the Crimean coast. Analysts are searching the imagery for more vessels.
The northern group, in a line-astern formation, appears to be led by a tug boat. Behind it are two Ropucha class landing ships, another tug boat and a trailing Ropucha.
The second group, in the middle, are in a square formation. These appear to be smaller warships such as missile corvettes.
The southern group is led by the Slava Class cruiser Moskva. This appears to have two Alligator class landing ships, and the Ivan Gren class landing ship Pyotr Morgunov. There is also a smaller warship, possibly a Buyan-M class missile corvette.
