About this opportunity
The 55th Contracting Squadron at Offutt Air Force Base, Nebraska is conducting sources sought market research on behalf of Air Force Weather (AFW) for a firm-fixed-price software steward for its next-generation Numerical Weather Prediction (NWP) model verification and development, with responses due November 12, 2026. No set-aside is used, and no solicitation exists; the notice does not commit the Government to an acquisition approach. The notice is posted under Department of the Air Force Air Combat Command and is classified under NAICS 541512. The contractor would serve as the unified, authoritative software steward for AFW's core modeling and data assimilation baselines, with the stated aim of avoiding forked or branched codebases. The Government welcomes responses from potential IDIQ prime contractors and from specialist small-business software and computational-engineering firms offering defined work packages as subcontractors or team members. Stated contribution areas include Python/C++ scientific software development, numerical-method implementation, test automation, model-output analysis, verification tooling, and integration support. The Q&A file identifies UCAR as the current incumbent. Questions closed November 6, 2026 at 4:30 p.m., and answers were released November 10, 2026. Submissions must be made on behalf of a single entity, and responses must address the posted Sources Sought Questions. Submissions are voluntary and uncompensated, and the Government will not respond to requests for a solicitation.
