AI Contract Overview
The National Oceanic and Atmospheric Administration’s Acquisition and Grants Office, Eastern Acquisition Division-Kansas City, intends to award a sole source purchase order to Vaisala for replacement RS41-SGP radiosondes to be delivered to the National Logistics Support Center in Grandview, Missouri. This procurement is authorized under FAR 6.103-1 due to Vaisala’s exclusive status as the manufacturer of the Line Replaceable Units integrated into the Automatic Radiosonde Observing Systems used by the National Weather Service since its inception. These radiosondes are essential for collecting critical atmospheric data—including temperature, humidity, barometric pressure, and wind—at various altitudes during weather balloon launches, directly supporting the accuracy of weather forecasts and forecasting models. The procurement is non-competitive and driven by the unique technical integration and proprietary nature of Vaisala’s components, which cannot be replicated by other vendors. This pre-solicitation notice does not constitute a request for competitive proposals, and no formal solicitation package is available. However, any firm asserting the ability to meet the government’s requirements may submit substantiating documentation or a request for additional information in writing to Contract Specialist Nikki Smith no later than July 25, 2026. Submissions will be evaluated solely to determine whether a competitive procurement is warranted, though the decision to proceed non-competitively remains at the government’s sole discretion. Oral communications are not accepted, and responses must be in writing. The contract will be managed under NAICS code 334519, with performance located in Grandview, Missouri, and all correspondence directed to the designated point of contact in Norfolk, Virginia.
