Russia is building at least six new nuclear submarines equipped with long-distance cruise missiles, according to state-connected news agency Itar-Tass. One is expected to be on line by 2011, the rest by 2017. A Russian defense ministry source say the missiles, capable of carrying low-capacity nuclear warheads, "would be designed for strikes on aircraft carriers of the enemy" as well as land targets.

Russia has said boosting its nuclear arsenal is necessary to counter a massive NATO advantage in conventional weapons. (Read more Russia stories.)
