The bill directs the Under Secretary (NOAA) to establish a “Radar Next Program” to design and implement a replacement for the National Weather Service’s Next Generation Weather Radar (NEXRAD) network. It requires development of performance and coverage requirements, collaboration with the weather enterprise to identify candidate solutions, and preparation of a detailed plan for replacing NEXRAD.
The bill also authorizes technology testing (including phased-array radars), a radar testbed to evaluate commercial and small gap-filling systems, and limited use of partnerships or contracts with non‑NOAA entities (a “radar-as-a-service” approach) to fill coverage gaps. It sets a hard implementation target — full execution of the plan by September 30, 2040 — and requires periodic updates to congressional committees.
At a Glance
What It Does
Establishes a NOAA-led program to define requirements, test technologies (including phased-array radars), evaluate commercial and small radar options in a dedicated testbed, and create a plan to replace the current NEXRAD network. It authorizes partnering with external entities to supplement radar coverage and data.
Who It Affects
NOAA and the National Weather Service, commercial radar manufacturers and service providers, mesonet and local radar operators, emergency managers and utilities that rely on radar data, and federal procurement and contracting offices. It also targets coverage improvements in U.S. territories and areas more than 75 miles from existing NEXRAD sites.
Why It Matters
Modernizing NEXRAD will alter the data backbone used for forecasts and warnings, open procurement and operations to commercial and local partners, and set technical requirements that will shape the market for weather sensors and data services for years.

What This Bill Actually Does
The bill creates a formal program inside NOAA, led by the Under Secretary with input from the National Weather Service, charged with replacing the aging NEXRAD radar network. The program must first define measurable performance and coverage standards so any new architecture can be judged against concrete goals for reach, accuracy, and low-level detection.
Those standards drive downstream choices about technologies and deployment patterns.
Once requirements exist, the Under Secretary must work with the “weather enterprise” — private vendors, academic researchers, and local operators — to identify candidate solutions. The bill mandates a phased-array radar development effort to nail down technical specifications and a separate testbed expressly for evaluating commercial radars and smaller, gap-filling systems.
The testbed is meant to answer practical questions that laboratory studies do not: how different vendor systems assimilate into operational models, how they perform in complex terrain, and how they hold up over time and scale.The statute authorizes NOAA to contract or partner with outside entities to fill gaps in coverage — the so-called radar-as-a-service model — and instructs the agency to consider mesonets, cooperative research agreements, and observational aids like weather cameras. The plan must spell out prioritized initial deployment sites, expected new sites (including those more than 75 miles from current NEXRAD stations), and quantified improvements in forecast and warning capability.
Finally, the Under Secretary must take steps to ensure the plan is implemented by September 30, 2040, and provide periodic implementation updates to the relevant congressional committees.
The Five Things You Need to Know
The bill requires the Under Secretary to develop quantifiable performance and coverage requirements for replacing NEXRAD, not just a technology wishlist.
It mandates a phased-array radar development program and testbed specifically to evaluate phased-array and commercial radar candidates before broader procurement.
The statute establishes a weather surveillance radar testbed to evaluate commercial radars and small gap-filling systems and to provide technical assistance to local partners.
The Under Secretary may use partnerships or contracts (radar-as-a-service) with non‑NOAA entities — including National Mesonet participants and commercial vendors — to supplement radar coverage and data assimilation.
The bill requires full implementation and execution of the replacement plan no later than September 30, 2040, and periodic updates to Senate and House science and commerce committees.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Provides the Act’s short name: the 'Radar Next Program Act of 2026.' This is a formal labeling provision and triggers the bill’s references in subsequent documentation.
Establish Radar Next Program
Directs the Under Secretary (per the Weather Research and Forecasting Innovation Act definitions) to establish the program in consultation with the National Weather Service. This creates a designated office-level responsibility inside NOAA to coordinate technical, procurement, and partnership activity rather than leaving modernization to ad hoc projects.
Define requirements and collaborate with the weather enterprise
Requires NOAA to develop specific performance and coverage requirements for the United States radar network (including territories) and to collaborate with private, academic, and local stakeholders to identify solutions that meet those requirements. Practically, this forces NOAA to produce objective metrics that will frame procurement specifications and vendor evaluation criteria.
Plan to replace NEXRAD with required elements and deadline
Obligates NOAA to prepare a plan that: estimates quantifiable performance gains for candidate replacements; runs a phased-array radar development track; implements the November 15, 2023 NESDIS Science Advisory Board report recommendations when applicable; establishes a testbed for commercial and gap-filling radars; gathers stakeholder input (academia, emergency managers, utilities); prioritizes deployment sites; identifies expected new sites (including those >75 miles from existing NEXRAD stations); and estimates forecast/warning data improvements. It also requires NOAA to take actions necessary to fully implement the plan by September 30, 2040, making the planning exercise tied to a concrete procurement/implementation schedule.
Authority for radar-as-a-service partnerships
Authorizes NOAA to partner or contract with entities outside the agency to fill radar data gaps and maintain network performance. The provision explicitly contemplates leveraging testbed participants, the National Mesonet Program, cooperative research agreements, and weather camera systems. This creates a formal contracting pathway for external data providers and clarifies the types of technologies NOAA may integrate.
Reporting and definitions
Requires periodic implementation updates to the Senate Committee on Commerce, Science, and Transportation and the House Committee on Science, Space, and Technology. It also adopts existing statutory definitions for 'Under Secretary' and 'weather enterprise' from the Weather Research and Forecasting Innovation Act of 2017, anchoring governance and collaboration expectations in prior law.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- National Weather Service and NOAA — Receive a mandate and budgetary focus to replace aging infrastructure, clearer technical requirements to guide modernization, and authority to pilot new architectures and partnerships.
- Commercial radar manufacturers and service providers — Gain a predictable market signal and formal testbed to demonstrate systems to NOAA, increasing opportunities for procurement and for providing radar-as-a-service contracts.
- Local and state mesonet operators, tribal governments, and utilities in radar-gap regions — The bill funds evaluation of small, gap-filling radars and technical assistance that can improve low-level and localized detection where large radars are ineffective.
- Emergency managers, public safety agencies, and weather-dependent industries (aviation, energy, agriculture) — Should receive better spatial and temporal radar coverage and higher-fidelity precipitation and severe-weather data once replacements are specified and deployed.
- Academic and research institutions — Benefit from formal consultation requirements, testbed access, and clearer data streams for modeling and verification work.
Who Bears the Cost
- NOAA/Under Secretary — Must plan, run development and testbed efforts, manage partnerships, and meet a 2040 implementation deadline without dedicated appropriations in the text; this creates resource and execution risk for NOAA operations.
- Federal procurement and contracting offices — Face complex solicitations and oversight demands for hybrid architectures and radar-as-a-service contracts, increasing transaction costs and acquisition complexity.
- Local partners and small mesonet operators — May need to meet interoperability and data-standard requirements to participate in federal systems or contracts, requiring investment in instrumentation and data pipelines.
- Commercial vendors — Must invest in demonstration projects and meet technical/performance criteria under testbed evaluations before winning contracts; this front-loads R&D and compliance costs even as it expands market opportunity.
Key Issues
The Core Tension
The bill forces a classic trade-off: accelerate and broaden radar coverage by embracing commercial partners and small gap-fillers, or preserve federal control and continuity by investing in a wholly government-owned replacement system. Speed, cost, and market stimulation pull toward public‑private approaches; control, standardization, and long-term data quality pull toward federally owned and operated systems — and the bill provides authority for both without resolving which will dominate.
The bill frames a comprehensive modernization program but leaves key implementation levers unspecified. It mandates requirements, testing, and a 2040 implementation target without attaching funding or specifying procurement authorities beyond permissive contracting language.
That gap means modernization depends on future appropriations and detailed acquisition strategy; the program could be under-resourced or delayed if funding does not match the statutory ambitions.
Relying on commercial providers and radar-as-a-service partnerships trades federal control for faster, potentially lower-cost coverage, but raises data quality, continuity, procurement integrity, and vendor‑lock concerns. The statute requires a testbed and phased-array development, but it does not define evaluation metrics, data standards, or how vendor-generated data will be certified and integrated into operational models.
Those choices determine whether a hybrid architecture actually improves forecasts or merely adds disparate data streams that increase assimilation complexity and maintenance overhead.
