Vertical Launching System (VLS) Deck and Hatch Assembly

The Naval Surface Warfare Center, Port Hueneme Division is preparing to procure the Deck and Hatch Assembly for the MK 41 Vertical Launching System under a Firm Fixed Price Single Award Indefinite-Delivery-Indefinite-Quantity (IDIQ) contract with a five-year ordering period. The effort, identified by solicitation number N6339426R4002, falls under NAICS code 332999 with a size standard of 750 employees and is set for full and open competition without any socioeconomic set-asides. The Request for Proposal is anticipated to be issued around May 2026, with responses due by May 13, 2026, and will be accessible through the PIEE portal and SAM.gov, with technical drawings and data shared via the DoD SAFE system to registered requestors. The contract will require the full fabrication, assembly, and testing of the assembly, including eight cell hatches, one uptake hatch, mechanical operating components, and a deluge cooling system, all conforming to detailed Technical Data Package specifications and form, fit, and function criteria. Special requirements include strict adherence to counterfeit parts prevention standards per SAE AS5553 and AS6174, mandatory ITAR compliance with DDTC registration and controlled foreign national access, and prohibition of ozone-depleting substances like CFC-113 and 1,1,1-Trichloroethane. All materials must be traceable from raw stock to finished product with certified material test reports, and limited shelf-life components such as epoxies and adhesives require prominent labeling and expiration control. Welding must follow NAVSEA S9074-AQ-GIB-010/248 and /148 standards, with qualified welders and procedures, and machining requires 100% visual and non-destructive testing on critical surfaces. Quality systems must align with ISO 9001 or ANSI/ASQC Q9001, and a formal Quality Control Program Plan must be submitted and approved. Configuration management is stringent, requiring an As-Built Configuration List and full documentation via CDRLs A001 through A007, including delivery of technical data with Government purpose or unlimited rights. Final acceptance occurs at the contractor’s facility, documented via DD Form 250 and Program Quality Acceptance signatures, with the Government retaining inspection rights across all facilities and supply chain tiers.
