Polish state-owned company PGZ and Estonia's Frankenburg Technologies will partner to produce ultra‑short‑range air defence systems in Poland. The move is part of efforts to expand Europe's capabilities against drones. The companies will create a plant with an annual capacity to produce up to 10,000 MARK I missiles that they are developing to counter unmanned aerial vehicles. The agreement also outlines a framework for developing the next-generation MARK II interceptor.
