Russia is alarmed by the U.S. Navy’s decision to deploy low-yield nuclear missiles on submarines since they heighten the risk of a limited nuclear war, a Russian official said on Wednesday. Deputy Foreign Minister Sergei Ryabkov said the deployment of the W76-2 warhead in the name of strengthening deterrence had caused Russia great concern over U.S. nuclear strategy, Russian news agencies reported. The U.S. Defense Department said on Tuesday the Navy had fielded a low-yield, submarine-launched ballistic missile warhead, something the Pentagon says is needed to deter adversaries like Russia.
