The NATO missile defense system is a missile defense system being constructed by the North Atlantic Treaty Organization (NATO) in several member states and around the Mediterranean Sea. Plans for this system have changed several times since first studied in 2002, including as a response to Russian opposition.
A Missile defence Feasibility Study was launched after the 2002 Prague Summit. The NATO Consultation, Command and Control Agency (NC3A) and NATO’s Conference of National Armaments Directors (CNAD) were also involved in negotiations. The study concluded that missile defence is technically feasible, and it provided a technical basis for ongoing political and military discussions regarding the desirability of a NATO missile defence system. The United States negotiated with Poland and the Czech Republic over the course of several years after on the deployment of interceptor missiles and a radar tracking system in the two countries. Both countries' governments indicated that they would allow the deployment.
In April 2007, NATO's European allies called for a NATO missile defence system which would complement the American national missile defense system to protect Europe from missile attacks and NATO's decision-making North Atlantic Council held consultations on missile defence in the first meeting on the topic at such a senior level. In response, Russian Prime Minister Vladimir Putin claimed that such a deployment could lead to a new arms race and could enhance the likelihood of mutual destruction. He also suggested that his country would freeze its compliance with the 1990 Treaty on Conventional Armed Forces in Europe (CFE)—which limits military deployments across the continent—until all NATO countries had ratified the adapted CFE treaty. Secretary General Jaap de Hoop Scheffer claimed the system would not affect strategic balance or threaten Russia, as the plan is to base only ten interceptor missiles in Poland with an associated radar in the Czech Republic.
