What the government is buying
The U.S. Navy is soliciting offers for work on the USNS Earl Warren (T-AO 207), a John Lewis-class fleet replenishment oiler. The scope involves ROH/UWILD, which stands for Restricted Overhaul / Underwater Inspection in Lieu of Drydocking—a major maintenance period for naval vessels.
ROH work typically encompasses extensive repairs, modernization, and system overhauls while the ship remains waterborne, without needing full drydock entry. UWILD allows the Navy to defer drydocking by conducting underwater hull inspections using divers and specialized equipment. For a fleet replenishment oiler like the T-AO 207, this work generally includes hull preservation, tank maintenance, machinery overhauls, piping repairs, and various habitability and mission-system upgrades. see the solicitation for the complete statement of work and technical requirements.
NAICS 336611 covers Ship Building and Repairing, confirming this is vessel repair work performed at the industrial level required for active Naval Service Force ships.

Who can bid
This solicitation is full and open with no small-business set-aside, meaning any responsible source can compete—including large shipyards, mid-tier contractors, and small businesses with adequate capacity and past performance. However, the complexity of ROH/UWILD work on a fleet oiler creates substantial barriers to entry.
Bidders typically need:
- Active SAM.gov registration and valid CAGE code
- Facility clearances and waterfront access capable of accommodating a 746-foot replenishment oiler
- Navy vessel repair experience, preferably with Military Sealift Command or Naval Service Force ships
- MARMC-qualified production processes or equivalent quality systems
- Subcontractor relationships for specialized trades (diving/hull inspection, tank cleaning, propulsion system work)
Small businesses without direct waterfront capacity may still participate through mentor-protégé arrangements, subcontracting to a prime, or teaming agreements—particularly if they hold unique capabilities in areas like marine engineering, electronics, or specialized coatings.
How to put together a competitive bid
Review the technical requirements meticulously. ROH/UWILD solicitations typically include detailed specifications, drawings, and a Reserve Fleet Maintenance Activity Process Control Procedure. Identify every system and subsystem requiring overhaul, and map your capabilities against each.
Assess your waterfront infrastructure early. T-AO vessels require significant pier space, crane capacity, and laydown areas. If the performance location is in Yokosuka's area of responsibility, evaluate logistics for material movement and labor deployment.
Price the UWILD portion carefully. Underwater work involves contracted diving services, hull cleaning, non-destructive testing, and potential hull coating touch-ups. Sourcing qualified diving contractors in the theater affects both cost and schedule risk.
Highlight relevant past performance. Navy evaluators weight recent, similar ship repair contracts heavily. Document your experience with T-AO class ships, prior ROH periods, or comparable Military Sealift Command maintenance contracts.
Evaluate bonding and financing requirements. Major ship repair contracts carry substantial upfront material costs and extended performance periods. Confirm your surety capacity and cash flow projections align with the government's payment schedule.
