Also on Wednesday, Russian Defense Minister Sergei Shoigu revealed plans to arm its strategic nuclear submarines with long-range precision weapons.

"This will significantly enhance the possibility of using submarines as a strategic deterrent," Shoigu told a meeting with the Pacific Fleet's submarine command.

Russia plans to build eight Borei-class submarines to form the core of its nuclear deterrence strategy by 2020, which will replace the Project 941 (Typhoon by NATO classification) and Project 667 submarines.
