On March 28, Poland signed a $4.75 billion contract with the United States for the first phase of a Patriot air and missile defense system. According to one report, phase one of the deal has Poland receiving two Patriot batteries consisting of 16 launchers and a presently undisclosed number of sectored radars, PAC-3 Missile Segment Enhancement (MSE) missiles, and accompanying supplies and technical support. In phase two, Poland will purchase six more Patriot batteries and related materials. Patriot producer Raytheon will start deliveries of rockets and communication systems in 2022, and initial operational capability of the system is expected by early 2024. “It is an extraordinary, historic moment; it is Poland’s introduction into a whole new world of state-of-the-art technology, modern weaponry, and defensive means,” Poland’s President Andrzej Duda said during the signing ceremony. This is the largest weapons procurement deal in Polish history, and the first international purchase of the Integrated Air and Missile Defense Battle Command System (IBCS).
