The Bradley Fighting Vehicle program requires on-site technical support for up to sixty days, providing engineering, logistics, and subject matter expertise on the Improved Bradley Acquisition Subsystem (IBAS) and TOW 2 Subsystem (T2SS). Services include system integration, fault isolation, diagnostics, test validation, and real-time technical guidance at the Cherokee Nations facility in Huntsville, AL. This is a sole-source acquisition restricted to On Point Defense Technologies LLC, and it is not a request for competitive proposals. The effort will be issued under an existing contract, and the data needed for competitive procurement is not available economically or practically. Interested firms that can meet prequalification requirements are encouraged to seek source approval for future solicitations.
