UK Ministry of Defence says Warsaw plan sets out missile and ammunition cooperation with Poland
The UK and Poland signed a Warsaw Defence Plan on October 27, 2026, covering cooperation on next-generation air-defence missiles, drones, counter-drone systems and ammunition production. BAE Systems and Poland's PGZ will expand large-calibre ammunition capacity, while the governments pursue closer procurement coordination building on the Narew air-defence programme. The three-year plan implements the countries' security and defence partnership treaty and also covers cybersecurity, training and industrial workforce cooperation. Naval activity will draw on the common design of Britain's Type 31 and Poland's Miecznik frigates, with additional Baltic exercises and coordination to protect maritime communications.
