MOSCOW, Nov. /TASS/. 7. The Pacific Fleet’s Ufa submarine, armed with Kalibr missiles, is making a call to the Indonesian port of Surabaya, the fleet said in a statement.

It is escorted by the rescue tug Alatau.

"While at the Indonesian port, Russian sailors will hold a number of formal events such as meetings with representatives of the Indonesian Navy, friendly volleyball matches, and will visit local attractions," the statement said.

The Ufa is heading from the Baltic Sea to join the Pacific Fleet.

Earlier, a flotilla of Russian naval ships including the corvettes Gromky, Rezky and Hero of the Russian Federation Aldar Tsydenzhapov called at Surabaya for the first joint exercise of Russian and Indonesian warships, which is called Orruda-2024.
