Water Filled Test Weight

DEPT OF DEFENSE.DEPT OF THE NAVY.NAVSEA.NAVSEA WARFARE CENTER.NUWC DIV NEWPORT · Response deadline: Tue, 13 Oct 2026

What the government is buying

The Naval Undersea Warfare Center (NUWC) Division Newport is procuring water filled test weights under a total small business set-aside. Water filled test weights are specialized equipment used in testing and calibration applications, particularly in maritime and undersea warfare contexts where precise weight measurements are critical for equipment validation and system testing.

NUWC Division Newport is the Navy's full-spectrum research, development, test and evaluation center for undersea warfare. The division conducts extensive work on submarine systems, undersea weapons, and related technologies, often requiring precise test equipment for laboratory and field validation. Test weights in this environment likely support buoyancy testing, pressure vessel calibration, torpedo and vehicle testing, or other undersea system verification activities.

The classification code 6635 (Physical Properties Testing and Inspection) further indicates this acquisition supports material testing, measurement, and quality assurance functions central to NUWC's mission.

Key facts

Who can bid

This opportunity is a total small business set-aside, meaning only small business concerns certified as small under NAICS code 332439 may bid. NAICS 332439 covers "Other Metal Container Manufacturing," which includes manufacturing of metal containers, tanks, and similar products—consistent with fabricating water-filled test weights that may incorporate metal components, valves, fill ports, and structural elements.

To qualify, your business must:

• Be registered and active in the System for Award Management (SAM.gov)
• Have a current small business size standard determination for NAICS 332439 (see the solicitation for the applicable size standard)
• Meet any applicable socioeconomic certifications if the solicitation includes additional requirements

How to put together a competitive bid

Given the specialized nature of defense test equipment, successful bidders on NUWC solicitations typically demonstrate:

Technical capability. NUWC test weights likely require precision manufacturing tolerances, corrosion-resistant materials suitable for maritime environments (stainless steel, coated alloys), and pressure ratings appropriate for undersea applications. Document your quality management system—ISO 9001 or AS9100 certification strengthens proposals for Navy test equipment.

Past performance. Highlight relevant deliveries to Navy commands, other DOD test facilities, or similar precision weight/metrology equipment contracts. NUWC evaluates track records with defense quality requirements and Navy-unique specifications.

Cost realism. Combined synopsis/solicitation notices often move quickly to award. Ensure your pricing accounts for material costs (specialty metals, precision machining), any required testing or calibration certificates, and compliance with DFARS clauses typical of Navy procurements.

Compliance precision. Navy warfare centers enforce strict solicitation requirements. Address every specification and clause; deviations risk automatic rejection.

Next steps

1. Read the full solicitation immediately on SAM.gov using solicitation number N6660427Q0006—the combined synopsis/solicitation format means the full request for quotation and applicable terms are available there.
2. Note the deadline: October 13, 2026, at 2:00 PM EDT—this is an unusually short response window typical of simplified acquisition procedures, leaving approximately one week from posting to respond.
3. Verify your SAM registration and small business status are current before preparing your offer.
