BOLSHOI KAMEN /Primorye/, March 7. /TASS/. Project 949A Antey nuclear-powered submarines will be rearmed with Kalibr missile systems after a profound upgrade at the Zvezda shipyard in the Russian Far East, Deputy Defense Minister Yuri Borisov said on Tuesday.

"The Zvezda shipyard is carrying out profound modernization of Project 949A nuclear submarines, including the replacement of armament with the Kalibr missile complex and also the replacement of navigation, life support and other systems," Borisov said.
