The Naval Surface Warfare Center Dahlgren Division intends to award a sole-source contract to Worldwide Counter Threat Solutions (WCTS) for specific weaponeering training courses and materials. The requirement is for the delivery of these products to Dahlgren, VA 22448-5114, with all associated shipping and duty costs included in a firm fixed price. Proposals are due by 12:00 p.m. EST on January 9, 2026, with an anticipated award by January 15, 2026. The justification for sole source is that the required software is exclusive to WCTS, and changing providers would disrupt instructional consistency and increase costs. To be considered, an offeror must be an authorized reseller of WCTS, registered in SAM, and the award will be made on a Lowest Price Technically Acceptable basis.
