The Department of Defense, specifically the Naval Surface Warfare Center (NSWC) Crane Division, is issuing a Request for Information (RFI) and Sources Sought notice for the procurement of the pyrotechnic lead shock tube, MK 34 MOD 0. The government is seeking information from potential vendors who can provide this product, which is critical for supporting the Naval Sea Systems Command Program Executive Office-IWS3C, while also addressing the sole source basis for the anticipated contract with Ensign Bickford Aerospace and Defense Inc. Interested companies must demonstrate their capabilities, provide technical data, and show that they can meet the necessary safety and certification requirements without incurring additional testing costs. Responses are due by March 24, 2025, and should be directed to Heather Summers or Andrew Ficklin via the provided email addresses. Note that no funding is currently available for this effort, and participation does not guarantee a contract award.
