The contract involves the GCA-2000 radar model, which provides air traffic control support, accurate approach guidance, and precise landings for aircraft.

In its mobile configuration, the radar can be powered by electric generators without needing a base power supply.

The system is also available in a fixed configuration.

The principal contractor will be Florida-based L3Harris, the Pentagon said.

The U.S. Defense Security Cooperation Agency (DSCA) said in a statement: “This proposed sale will support the foreign policy goals and national security of the United States by improving the security of a NATO Ally that is a force for political and economic stability in Europe.

“The proposed sale will improve Poland’s capability to meet current and future threats by bolstering its capabilities in air traffic control and reinforcing its commitment to provide secure and effective aviation services in accordance with international norms, while expanding its national defense capabilities and supporting the common defense of NATO.”

It added: “Poland will have no difficulty absorbing these additional systems into its armed forces.” Poland had previously expressed the need for nine units of this equipment back in 2012, tvp info, a website of the news channel run by the Polish public broadcaster TVP, has reported.

At that time, the contract was valued at $200 million, with the main contractor being ITT Exelis Inc., based in California.
