Russia's proposed fifth-generation nuclear submarines will be armed with both ballistic and cruise missiles, a senior Navy source told RIA Novosti on Saturday.
He did not specify the names of the missiles.
Russia is planning to develop its newest fifth-generation submarine by 2020 under a 2011-2020 arms procurement program, First Deputy Defense Minister Vladimir Popovkin said last month.
Russia also plans to build eight fourth-generation strategic nuclear submarines by 2020 and equip them with Bulava submarine-launched ballistic missiles, which are expected to be put into service this year.
Defense Ministry submitted the 19 trillion ruble ($651 billion) arms procurement spending plan for 2011-2020 to the government in December. Some 80% of the funds will be spent on buying weapons and 10% will be spent on scientific research.
