PAC-3 MSE Poland: Why the U.S. Picked It for Patriot Repairs

Poland Chosen to Host European PAC-3 Missile Maintenance Facility for NATO’s Patriot Operators

The U.S. has picked Poland to host Europe’s PAC-3 MSE missile maintenance facility, where Lockheed Martin will repair and recertify NATO’s Patriot interceptors.

The United States has selected Poland to host the European PAC-3 Missile Maintenance Facility, a dedicated site for servicing the interceptors fired by the MIM-104 Patriot air defence system, with the Department of War announcing the decision on October 27 on the margins of a NATO Conference of National Armaments Directors meeting in Brussels. Lockheed Martin, which manufactures both the PAC-3 MSE and the older PAC-3 Cost Reduction Initiative missile, will establish the facility to provide repair, refurbishment, lifecycle support and recertification for allied interceptors, while Germany, the Netherlands and Sweden lead the integration of its supply chain. The site within Poland, the cost of the facility and the date it is expected to open were not disclosed. The choice places Patriot sustainment on NATO’s eastern flank, in the country that has made one of the largest Patriot purchases anywhere outside the United States.

Under Secretary of War for Acquisition and Sustainment Michael P. Duffey said that by investing in the facility “on NATO’s Eastern Front, Allies are sending a clear message: the Alliance is united, serious about deterrence, and ready to back our words with action.” The selection follows a government-to-government agreement signed by the United States, Germany, the Netherlands, Poland and Sweden on July 7 at the NATO summit in Ankara, which committed the five to explore a maintenance site in Europe, while Polish Prime Minister Donald Tusk stated that Poland had worked hard to win it against several competitors, according to Defense News. The decision comes as Lockheed Martin expands output considerably, with a January framework agreement aiming to triple PAC-3 MSE production capacity and the U.S. government having awarded the company $58.62 billion this year for multiyear production of a missile that costs between $4 million and $5.3 million per round by most estimates.

Poland’s own investment under the Wisła program explains much of the choice. A first phase contract signed on March 28, 2018 and valued at around $4.75 billion covered two Configuration 3+ batteries with 16 launchers and 208 PAC-3 MSE interceptors, and Warsaw announced in December 2025 that both batteries had reached full operational readiness. The second phase is significantly larger, with a sale notified by the U.S. Defense Security Cooperation Agency in June 2023 covering 48 M903 launchers, up to 644 PAC-3 MSE missiles and 12 Lower Tier Air and Missile Defense Sensor radars, and Poland’s Armament Agency expecting the final deliveries by the end of 2028.

European demand for the PAC-3 MSE has outpaced supply, with Ukraine’s shortage of Patriot interceptors the most visible consequence, and Germany, Poland and Ukraine have been among the states lobbying Washington for the missile to be produced in Europe. Those talks on local manufacturing are continuing separately, and the facility announced in Poland will repair and recertify interceptors rather than build them. France has meanwhile continued to expand its fleet of the rival SAMP/T NG system, ordering four more firing units in October to bring its planned total to 12, with ten of them expected in service by the end of 2030.
