The largest military ship of Ukraine was for repairs in Chernomorsk. This is reported TSN.
On the eve of the frigate "Hetman Sagaidachny" several hours were brought into the floating dock with the help of two powerful tugboats. Ship repairmen even had to cut out in the deck of the dock a special hole, so that the hull of the ship would become exactly there.
Under the water, the whole process was constantly monitored by four divers.
After all the water was pumped from the dock, the lower part of the ship's hull opened. It will be cleaned of the growths of marine organisms and will repair the steering screws.
The full repair plan is kept secret by the military.
