Ukrainian armed forces named the Russian landing ship they say they attacked and destroyed in Berdyansk as the "Saratov," in a statement on Friday.
In earlier reporting, the ship was named as the "Orsk."
“In the Azov operational zone, according to updated information, a large landing ship 'Saratov' was destroyed during the attack on the occupied Berdyansk port," the statement said.
The statement identified the two other large landing ships -- the "Caesar Kunikov" and "Novocherkassk" -- that were also said to have been destroyed during the attack.
"Other losses of the enemy are being clarified," the statement said.
The port, which had recently been occupied by Russian forces with several Russian warships in dock, was rocked by a series of heavy explosions soon after dawn.
Social media videos showed fires raging at the dockside, with a series of secondary explosions reverberating across the city.
Several Russian ships had been unloading military equipment at Berdyansk in recent days, according to reports from the port by Russian media outlets.
