According to British intelligence, the restoration of the Rostov-on-Don submarine, which was damaged by a missile attack, will take a long time and require large financial costs. 

The intelligence report published by the UK Ministry of Defense on Twitter emphasizes that on September 13, a missile attack hit the Sevmorzavod shipyard on the territory of the Sevastopol naval base of the Russian Black Sea Fleet. The attack damaged the landing ship Minsk and the submarine Rostov-on-Don, which were undergoing maintenance in dry docks.

"Despite the fact that the Russian Ministry of Defense downplays the damage to the vessels, open source data indicates that the Minsk is almost certainly functionally destroyed and the Rostov has probably suffered catastrophic damage... Any attempts to bring the submarine back into service are likely to take many years and cost hundreds of millions of dollars," the report says.

This creates serious technical problems for the Russian Black Sea Fleet in the field of maintenance, the report emphasizes. According to British intelligence estimates, the task of removing the wreckage from the dry dock will take many months.

The report also emphasizes that the loss of the Rostov-on-Don submarine creates serious difficulties for the Russian Black Sea Fleet, depriving it of one of the four submarines capable of carrying cruise missiles. These submarines "have played an important role in striking Ukraine and expanding Russian influence in the Black Sea and Eastern Mediterranean."
