The agreement signed between the Armament Agency, representing the State Treasury of the Republic of Poland, and PIT-Radwar concerns the modernization of nine long-range radar stations, including six NUR-12ME radar systems under the basic order and three NUR-12M radar systems under the optional order.

The total value of the contract is approximately 806 million gross PLN, including 562.7 million PLN for the guaranteed order and 243.5 million PLN for the optional one.
The modernization work will begin in 2025, with completion of the basic order scheduled for 2032 and the optional order for 2035.
The scope of the modernization includes changes to the sounding system, the method of radar echo signal processing, and training for operators, instructors, and maintenance and repair personnel.
After modernization, the NUR-12M and NUR-12ME radar stations will operate using a distributed solid-state transmitter (a semi-active antenna with transmit–receive modules arranged in antenna rows) with electronic control of the position and shape of the transmit and receive beams in the elevation plane. The new transmitting system will ensure a low level of out-of-band emissions, in accordance with the requirements of the Radio Regulations (RR) of the International Telecommunication Union (ITU).
Thanks to the modernization, the NUR-12M and NUR-12ME radar stations will gain the capability to detect, track, and classify air-breathing targets (ABT); detect, track, and determine the launch and impact areas of tactical ballistic missiles (TBM); detect anti-radiation missiles (ARM) homing in on electromagnetic emissions from the radar; detect unmanned aerial vehicles (UAVs) and hovering helicopters; perform friend-or-foe identification (IFF) in the Mark XIIA system with an S-mode interrogator; and transmit data to air-surveillance information processing systems.
The NUR-12M is a three-coordinate long-range radar designed for airspace monitoring. It enables the detection of aerial objects, determination of their coordinates (azimuth, distance, altitude), automatic tracking of selected targets, electronic identification in the Mark XIIA system, and bearing of active jamming sources. The radar can transmit radar information to air-picture compilation and analysis systems (e.g., DUNAJ) in the ASTERIX data format. It is designed to operate in harsh weather conditions and under passive and active jamming, occurring separately or simultaneously.
As part of the modernization, the radar antenna will be adapted for the implementation of transmit–receive modules in the antenna rows.
