The contractor delivers programmed dry-docking, cyclic maintenance, structural repairs, painting, and system modernization for a range of naval and Army watercraft, including Modular Warping Tugs, Causeway Ferries, Landing Craft Utility vessels, and small tugs. Their technical proficiency spans hull integrity restoration, propulsion system overhauls, corrosion control, and mission-critical modifications to extend vessel service life. Yokohama Engineering Works demonstrates consistent capability in executing complex, time-sensitive repairs under operational constraints, with particular skill in integrating modernization upgrades into legacy platforms without disrupting mission readiness. The company maintains an exclusive relationship with the Department of Defense, providing sustained support across Army and Navy maritime assets. Their work focuses on sustaining tactical mobility platforms used in logistics, amphibious operations, and harbor operations, indicating a trusted, long-term partnership built on reliability and adherence to military engineering standards. Yokohama Engineering Works is singularly focused on the shipbuilding and repair sector, with no diversification into other NAICS categories. They operate as a niche provider for military maritime infrastructure, specializing in the lifecycle management of small to medium-sized naval auxiliaries and support craft. Their market positioning is defined by precision execution in maintenance-intensive environments and a proven ability to deliver mission-critical repairs on demanding schedules. As a Japanese entity headquartered in Yokohama-shi, Kanagawa, the company operates under an X6 corporate structure with no federal certifications on record. While geographically based outside the United States, it maintains a dedicated presence in the U.S. defense supply chain, serving as a specialized offshore provider for high-value, technically demanding vessel sustainment work.

Multiple Ship Sustainment Partnership (MSSP) Single Award Indefinite Delivery Indefinite Quantity (SA-IDIQ) Contracts for Fleet Maintenance Availabilities and Incremental Selected Restricted Availabilities on DDG-51 Class Ships Homeported in Norfolk, VA
Solicitation # N0002426R4439
The Naval Sea Systems Command (NAVSEA) is preparing to establish a Multi-Ship Sustainment Partnership (MSSP) program for the DDG-51 class destroyer fleet through a Single-Award Indefinite Delivery/Indefinite Quantity (SA-IDIQ) contract vehicle, with performance centered at the Southwest Regional Maintenance Center in San Diego, California, and the Mid-Atlantic Regional Maintenance Center in Norfolk, Virginia. This initiative seeks to build long-term partnerships with qualified contractors to deliver consistent, responsive maintenance, modernization, and repair services by leveraging a pre-priced task menu for routine work and a structured Level of Effort (LOE) clause for emergent needs, aiming to reduce procurement delays and enhance operational readiness. Industry feedback is being actively solicited on key elements such as task order competition under a single-award structure, small business participation goals, pricing for time-based costs like temporary services, and the design of award and incentive fee structures at the task order level. The acquisition strategy prioritizes deep platform expertise, continuous repair learning, and industrial base stability, requiring contractors to hold a Tier 2 NAVSEA Master Ship Repair Agreement (MSRA), maintain Cybersecurity Maturity Model Certification (CMMC) compliance, and demonstrate proven past performance on Integrated Ship Repair Activities or Contractor Maintenance Availabilities lasting over 70 days within the past three years. Contractors must possess or have ready access to piers capable of accommodating DDG-51 vessels in either San Diego, Norfolk, or both, and provide detailed information on their workforce capacity, facility infrastructure, and organizational controls for quality assurance, production management, and safety. All participants are required to disclose their business size under NAICS code 336611—defined as small if the company has 1,300 employees or fewer—and must outline their plans for subcontracting to small businesses. Submitting a Notice of Interest is mandatory for participation in the market research phase, with requirements including company name, CAGE code, Unique Entity Identifier (UEI), primary homeport interest, and employee counts at each location. The Government has issued multiple sources-sought announcements and is holding a virtual industry day to refine its acquisition approach before issuing the formal Request for Proposal; responses to these pre-solicitation actions are limited to ten to fifteen pages and must be submitted via email to designated NAVSEA contracting personnel. The program emphasizes fixed-price structures, predictability, and efficiency, and no contract award or financial commitment is guaranteed at this stage, as this remains
