DEPT OF DEFENSE.DEPT OF THE NAVY.NAVSUP.NAVSUP WEAPON SYSTEMS SUPPORT.NAVSUP WSS PHILADELPHIA.NAVSUP WEAPON SYSTEMS SUPPORT · Response deadline: Mon, 23 Nov 2026
What the government is buying
The Navy's Naval Supply Systems Command (NAVSUP) Weapon Systems Support Philadelphia office is soliciting offers for repair and modification services related to a valve, ECS (Environmental Control System). This falls under broader aircraft parts and auxiliary equipment manufacturing and maintenance work. The Environmental Control System in military aircraft manages cabin pressure, temperature, and air quality—critical functions for crew safety and equipment performance.
Valve repair and modification contracts typically involve inspecting, overhauling, testing, and certifying components to meet strict military standards. Contractors may need to demonstrate capabilities in precision machining, welding, non-destructive testing, and adherence to NAVAIR or other military technical directives. The specific valve type and scope of repair versus replacement would be detailed in the full technical specifications.

Who can bid
This solicitation is open competition with no set-aside designation indicated in the metadata. Small businesses registered in SAM.gov with NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) may bid alongside other qualified offerors. Firms should verify their SAM registration is active and that any required small business certifications are current.
Given the technical nature of ECS valve repair, prospective bidders likely need experience with aerospace or defense component overhaul, relevant quality certifications (such as AS9100 or ISO 9001), and familiarity with military technical data and packaging requirements. The Defense Priorities and Allocations System (DPAS) may apply to this type of critical spare.
How to put together a competitive bid
For repair and modification solicitations without a set-aside, small businesses compete directly against larger firms on technical merit and price. Focus your proposal on:
Technical approach: Detail your repair methodology, turnaround times, and testing protocols. NAVSUP WSS prioritizes reliability and compliance with military specifications over rock-bottom pricing.
Quality systems: Highlight your AS9100D registration, NADCAP certifications for special processes, and any Navy-approved repair source status. Past performance on similar valve repairs strengthens your position.
Cost realism: Structure pricing to show thorough understanding of material costs, labor hours, and overhead. The Navy may evaluate for cost realism, not just lowest price.
Small business factors: Even without a set-aside, note any small business, veteran-owned, or HUBZone status in your proposal for potential subcontracting credit or source selection consideration.
Packaging and delivery: Military repair contracts have strict preservation, packaging, and marking requirements. Demonstrate compliance with MIL-STD-2073 or specific contract clauses.
Request the technical data package and any drawings early to assess feasibility and lead times for specialty materials.
