MOSCOW, April 9. /TASS/. Two frigates of project 22350 and two amphibious assault ships of project 11711 for the Russian Navy will be laid down at shipyards in St. Petersburg and Kaliningrad on April 23, Defense Minister Sergei Shoigu said on Tuesday.

"On April 23, several blue water ships will be laid - two frigates of project 22350 at the Svernaya Verf (Northern Shipyard) in St. Petersburg and two amphibious assault ships of project 11711 at the Yantar shipyard in Kaliningrad," Shoigu said at a distance conference on Tuesday.

"Alongside this the Northern Shipyard will couple two major hull units of the project 20386 corvette. It will be named after the military brig The Merkuriy, whose heroic feat will turn 190 in May," Shoigu said.

The frigates, amphibious assault ships and the frigate are to be provided for the Navy by 2025.

The Russian Navy currently has only one frigate of project 22350 - The Admiral Gorshkov, which entered service in July 2018. It is expected that the Russian military in December 2019 will receive a second ship of this type - The Admiral Kasatonov. The Northern Shipyard is building two more frigates of project 22350.

In June 2018, one amphibious assault ship of project 11711, The Ivan Gren, went operational. The Yantar shipyard is building another same type ship, The Pyotr Morgunov. The shipyard’s CEO Eduard Yefimov said at a certain point that the series of these ships would not be continued, but at the end of December 2018 the president of the United Shipbuilding Corporation, Alexei Rakhmanov, said that the Russian Navy would get another two or three ships of the same type, built according to an upgraded project.
