The Department of Defense, through the Naval Surface Warfare Center (NSWC) Crane Division, is issuing a Request for Information (RFI)/Sources Sought (SS) to gather insights on engineering services and supplies necessary for the sustainment and enhancement of the AEGIS Weapon System and AN/SPY Radar Signal Processor. This initiative aims to explore alternatives to a sole-source award to Lockheed Martin for a five-year Basic Ordering Agreement (BOA), which is being considered due to concerns over substantial duplication of costs and potential delays associated with competitive procurement. Interested contractors are invited to submit capability statements, product literature, and white papers to challenge the sole-source justification, with responses due by December 10, 2025, at 2:00 PM EST. For further inquiries, interested parties may contact Kathryn Muessig at Kathryn.m.muessig.civ@us.navy.mil or by phone at 812-381-7158.
