Russia is installing receivers for its Global Satellite Navigation System (GLONASS) on "smart" weapons, according to June 17 comments from Russian Deputy Defense Minister for Armaments Vladimir Popovkin. While specific information is unavailable, it is clear that Russia faces significant difficulties in operationalizing its efforts to incorporate satellite navigation guidance into its weapon systems. Nevertheless, the Russian military could be on the verge of turning a corner with precision-guided munitions (PGMs). Modern PGMs are an American invention rooted in U.S. military wartime experience. This is not to say that the Soviet military lacked guided weapons or failed to develop them during the Cold War.
