The companies will build a plant with an annual capacity to produce up to 10,000 MARK I missiles that they are developing to counter unmanned aerial vehicles."This is a significant development because, given the ongoing conflict in the Middle East and in Ukraine, Poland will have the capability to produce low-cost missiles capable of countering slow-flying drones," PGZ board member Marcin Idzik told a news conference.The agreement also sets out a framework for developing the next‑generation MARK II interceptor, which is expected to extend MARK I's effective range to 5-8 km (3-5 miles).Frankenburg Technologies' CEO Kusti Salm said that the defence sector must operate on an industrial scale if it is to counter "the Russian threat in this part of the world, which every one of you feels every day."The companies did not disclose the planned investment, specific plant location or expected production start date.
