NUWCDIVNPT intends a sole-source award to Woods Hole Oceanographic Institution (WHOI) in Woods Hole, MA for a Cost Plus Fixed Fee and Cost Only IDIQ contract supporting REMUS Autonomous Undersea Vehicle systems and advanced undersea communication subsystems across submarine and surface ship classes. Tasking includes evaluating REMUS hardware, firmware, and software plus design analysis and prototype assessment, with an anticipated 113,000 man-hours over a five-year ordering period. The sole-source rationale is that WHOI is the sole designer, original developer, and proprietor of core REMUS 600/3000 technologies and owns proprietary acoustic/optical communications source code, including NSA-approved encryption supporting Navy ATO compliance. The government states competition would be technically infeasible and cost-prohibitive and could cause a three- to five-year delay and mission gap. Further details are anticipated with solicitation issuance in December 2026, and responsible sources may submit capability statements, proposals, or quotations for consideration.
