This is a notice of intent to sole source, not a request for quote, and no RFQ will be issued. The Naval Air Warfare Center Weapons Division, China Lake, intends to award a firm-fixed-price contract to Ott HydroMet Corp. for Annual Leads 8.X Services and Support Services. The sole-source rationale is that Ott HydroMet’s Weather Analysis Data System software is proprietary and no other source can provide compatible upgrades and fixes. The original period of performance is 10/2/2026 to 9/30/2027.
