Russian ships are shelling targets in the suburbs of Odesa as naval activity ticks up in the Black Sea, the Pentagon said on Wednesday.
“We do see increased naval activity in the northern Black Sea,” a senior defense official told reporters on Wednesday.
We also have observed on our own the shelling of some town outside of Odessa near Odessa, but not in Odessa. We believe these are… from Russian warships in the Black Sea.
The official did not say if the shelling was a precursor to an amphibious landing near the port city.
“It could be that they are preparing the way for some sort of ground assault on Odesa,” the official said.
“We would not see them surprised in taking Odesa given its strategic location.”
The shelling follows a Tuesday mobilization of Russian amphibious warships off the coast of Odesa in the Black Sea that ultimately turned back to their staging area near Crimea.
Fourteen Russian ships were seen operating in off the southern coast of Ukraine, according to open-source analysts H I Sutton and Damien Symon earlier tracked a Russian amphibious assault group and two surface combatants operating near the coast of Odesa in the Black Sea.
“Two [groups] 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,” they wrote in Naval News.
In total, the pair saw 14 ships, led by a Russian minesweeper, approach the coast off Odesa and then turn back toward Crimea. Pentagon officials confirmed the basic details on Wednesday.
In late February, thousands of Russian troops landed on the Sea of Azov coast without resistance as part of the ongoing Mariupol siege. They have not yet made an amphibious landing in the Black Sea.
The Kremlin has moved six amphibious landing ships into the Black Sea since the start of the year to join landing ships that were already part of the Black Sea fleet.
These include three Ropucha-class tank landing ships, which are capable of landing 10 main battle tanks and 350 troops ashore. The larger Ivan Gren-class, also in the Black Sea, can move 13 main battle tanks and 300 troops while also fielding two attack helicopters.
According to notices to mariners, the sea approaches to Odessa and surrounding beaches are heavily mined, which would complicate a landing.
Russian amphibious forces aren’t skilled at contested amphibious landings and would need an uncontested beach to deploy vehicles and naval infantry.
