The Naval Surface Warfare Center Dahlgren Division intends to sole-source procure software from Green Hills Software, LLC, as an alternative brand would lead to substantial duplication of costs. The required software must be compatible with the currently installed system, and all costs including shipping to Dahlgren, VA 22448-5114 must be included in the quoted price. Offerors must provide documentation confirming they are an authorized reseller or distributor of the brand-name item. Award will be made on a Lowest Price Technically Acceptable basis, and firms must be registered in the System for Award Management (SAM). The anticipated award date is by 8 August 2026.
