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 U.S. Navy's Naval Supply Systems Command (NAVSUP) Weapon Systems Support Philadelphia office is soliciting bids for work related to aircraft engine blowers, specifically in the context of engineering and production support (EAPS) and repair or modification services. The formal title references "BLOWER,ENGINE,EAPS, IN REPAIR/MODIFICATION OF."
NAICS code 336412 covers the Aircraft Engine and Engine Parts Manufacturing industry. Companies in this classification typically manufacture, repair, overhaul, or modify aircraft engines and components—including auxiliary systems like blowers, which manage airflow for cooling, pressurization, or other engine functions. Blower assemblies in aircraft engines are critical components that require specialized technical expertise and often compliance with military specifications.
This solicitation contemplates contracting for technical services to repair or modify existing equipment rather than procurement of new manufactured items alone. The "EAPS" designation suggests the work involves ongoing engineering and production support, which in Navy aviation contexts typically encompasses technical data, logistics support, and sustaining engineering for fielded systems.

Who can bid
This solicitation is open to all responsible offerors; no small business set-aside applies. Large businesses, small businesses, and other eligible entities may compete.
Small businesses registered under NAICS 336412 with relevant capabilities should still consider bidding. Even in unrestricted competitions, small businesses can win Navy aviation contracts if they demonstrate:
- Technical competency in aircraft engine component repair/modification
- Access to qualified engineering personnel and specialized equipment
- Experience with military specifications (Mil-Spec) and defense quality systems
- Appropriate certifications (AS9100, NADCAP, or similar aerospace standards)
Firms without prior government contracting experience should verify their SAM.gov registration is active and that they hold any required Clearance and Certifications. See the solicitation for specific qualification requirements.
How to put together a competitive bid
Given the technical nature of aircraft engine blower repair and modification, bidders should focus on:
Technical approach: Clearly describe your repair methodology, inspection processes, and modification capabilities. NAVSUP WSS typically evaluates technical merit heavily for aviation sustainment contracts. Specify your engineering change proposal (ECP) process if design alterations are anticipated.
Quality and traceability: Emphasize your quality management system, material traceability procedures, and non-destructive testing (NDT) capabilities. Military aviation parts require rigorous documentation.
Past performance: Cite relevant contracts involving similar engine components, preferably for DoD or commercial aviation clients. Performance on previous NAVSUP or Navy contracts carries significant weight.
Pricing structure: Develop detailed cost breakdowns including labor rates (by skill category), material costs, and overhead. Repair contracts often use various pricing arrangements; see the solicitation for the specific contract type and pricing requirements.
Schedule and risk: Address your turnaround times, surge capacity, and how you manage long-lead or obsolete parts—common challenges in legacy military engine support.
