The US government, Lockheed Martin and European allies have selected Poland to host a maintenance facility for Patriot Advanced Capability-3 (PAC-3) missiles.

The announcement was made on the margins of a meeting of Nato’s Conference of National Armaments Directors (CNAD).

According to a 27 October Department of War (DoW) statement, Germany, the Netherlands and Sweden, the original signatories of the agreement alongside the US and Poland, will support the facility through the transatlantic supply chain.

The PAC-3 Missile Maintenance Facility (MMF) will carry out repairs, refurbishment, lifecycle support and re-certification for PAC-3 interceptors. It is intended to provide maintenance and testing capacity closer to the Nato allies operating the system.

Lockheed Martin indicated that the new facility will operate within Poland’s current defence industry network, supporting the development of specialised roles, broadening prospects for domestic suppliers, and contributing to local community investment to strengthen the alliance’s industrial capacity.

Lockheed Martin missiles and fire control president Tim Cahill said: “For more than 75 years, Lockheed Martin has been a trusted partner to Europe— strengthening regional sustainment, expanding production capacity and accelerating the delivery of critical missile defence capabilities.

“The PAC-3 MMF represents the next evolution of that partnership, bringing essential sustainment support to our European allies and ensuring these advanced defence systems remain available when and where they are needed most.”

The announcement aligns with defence industrial targets agreed at the Ankara Summit in July 2026 as part of the “Nato 3.0” initiative.

Nato members have increasingly focused on localising defence maintenance capabilities, with the Polish facility intended to reinforce supply security and efficient operational support in Europe’s eastern theatre.

DoW acquisition and sustainment under secretary Michael Duffey said: “By investing national resources to establish this critical sustainment capability 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 of Poland to host PAC-3 MMF follows the increasing demand for PAC-3 MSE.

In July, Lockheed Martin said it would triple PAC-3 MSE interceptor production by 2030 after receiving a new seven-year contract modification worth up to $53.86bn from the US government.

Combined with an earlier $4.7bn contract, this brings the multiyear total to $58.62bn.

Earlier this month, Lockheed Martin unveiled PAC-3 Edge, an interceptor competing in the US Army’s Future Interceptor programme.

Development and testing are scheduled to begin in 2027, with deployment planned after 2031.
