Head of the United Coordination Press Center of Southern Defense Forces Natalia Humeniuk stated this live on air of national TV marathon.
In the last 24 hours, Russia reduced the number of missile carriers in the Black Sea - from six to five.
"One of the submarines returned to the base, and this could indicate many things: problems, response to the storm or re-equipment. We still cannot identify certain moments from the last missile attack (January 14 - ed.)."
Activity of Russian UAVs has increased in recent days, and this may indicate preparations for a new massive missile attack on Ukraine.
"Total grouping consists of 11 warships, including those that launch reconnaissance drones," spokeswoman of OC South said.
On January 15, Natalia Humeniuk reported that during the massive missile attack on Ukraine on January 14, Russia used only half of Kalibr missiles that it had prepared in the Black Sea for the strike.
As of January 19, OC South reported: despite the storm, Russian invading forces continue to keep missile carriers in the Black Sea: 6 ships with a total volley of up to 40 Kalibrs are on combat duty.
