What the government is buying
This is a manufacturing contract for a B-52 Regulating Valve, National Stock Number (NSN) 4820-00-860-4396. The item falls under Federal Supply Classification (FSC) 4820, which covers valves, nonpowered. This type of valve is used in aircraft fluid systems to control pressure, flow, or direction of hydraulic, fuel, or pneumatic systems. For the B-52 Stratofortress—an aging but still active bomber platform in the U.S. Air Force fleet—new manufacture of spare parts supports sustainment and readiness as original equipment manufacturers may no longer produce these legacy items.

Who can bid
This solicitation is open to all responsible sources with no small-business set-aside. Large businesses, small businesses, and nontraditional defense contractors may all submit offers. Under NAICS 336413, bidders typically need capabilities in aerospace precision manufacturing, including machining exotic alloys, fluid system component fabrication, and military specification compliance.
To bid competitively, you'll generally need:
- Quality systems: AS9100D certification is standard for aerospace manufacturers and often expected by DLA Aviation
- Defense contracting experience: Either past performance directing to DLA or similar military customers, or a credible teaming arrangement
- Manufacturing traceability: The ability to produce to military specifications and maintain lot control, material certifications, and test records
- Small business status: While not required here, if you qualify as small under NAICS 336413's size standard (typically 1,500 employees), you retain future set-aside eligibility
How to put together a competitive bid
No set-aside means price and technical merit drive award. Focus on these areas:
Technical proposal: see the solicitation for exact specifications, but generally demonstrate your understanding of the drawing package, material requirements (likely stainless steel or nickel alloy), and any pressure/fluid compatibility requirements. Include your quality plan, inspection procedures, and any relevant past performance producing valves or similar aircraft components.
Pricing strategy: Research historical pricing through DLA's DIBBS system or FPDS for this NSN if previously procured. Legacy B-52 parts sometimes command premium pricing due to limited sources, but DLA will compare against market data. Account for tooling, first article inspection, and any test fixture costs.
Source of supply: If you are not the original manufacturer or design owner, assess whether technical data package access is available. DLA Aviation contracts for "New Manufacture" typically provide sufficient drawings for competitive bidding, but verify data rights and any required licensing.
Past performance: Prepare at least three recent, relevant contract references—ideally aerospace manufacturing for defense customers. Include points of contact and value information.
Cybersecurity and compliance: Ensure your NIST SP 800-171 self-assessment is current and posted in SPRS if required for your contract tier.
