This legislation establishes the Radar Next Program , tasking the Under Secretary, in consultation with the National Weather Service Director, to develop a comprehensive strategy for the future of the United States' weather radar network. The program requires the development of performance and coverage requirements for the network, including U.S. territories, and collaboration with the broader weather enterprise to identify potential solutions for updating the system. A key component of the program is the creation of a detailed plan to replace the existing Next Generation Weather Radar (NEXRAD) system . This plan must include estimates of quantifiable improvements, the development of a phased array radar for testing, and the establishment of a weather surveillance radar testbed to evaluate commercial options and provide technical assistance for gap-filling radars. The bill mandates that this replacement plan be fully implemented and executed by September 30, 2040 , ensuring continued and improved weather radar coverage. Furthermore, the bill introduces a "Radar-As-A-Service" provision, allowing the Under Secretary to partner or contract with external entities to fill data gaps in weather radar coverage. These partnerships aim to supplement low-level and wide-area coverage, ensure the network's continued performance, and enhance the detection of significant precipitation and severe weather across populated areas.
