ECP 6315C3 Navigation Warfare NAVWAR A-Kits for F/A-18E/F Aircraft
DEPT OF DEFENSE.DEPT OF THE NAVY.NAVAIR.NAVAIR HQS.NAVAL AIR SYSTEMS COMMAND · Response deadline: Mon, 28 Dec 2026
What the government is buying
The Naval Air Systems Command (NAVAIR) is seeking proposals for Navigation Warfare (NAVWAR) A-Kits for F/A-18E/F Super Hornet aircraft. NAVWAR systems protect military aircraft from GPS interference, jamming, and spoofing threats while maintaining reliable positioning, navigation, and timing capabilities. A-Kits in this context typically refer to installation hardware and structural provisions that enable integration of electronic warfare or navigation systems onto aircraft platforms.
This requirement supports the F/A-18E/F, the Navy's primary carrier-based strike fighter. The "ECP 6315C3" designation indicates this is an Engineering Change Proposal, meaning it modifies the existing aircraft configuration to accommodate new or updated NAVWAR capabilities. The work centers on aerospace manufacturing and integration at the component level.

Who can bid
This is a full and open competition with no set-aside preference for small business or socioeconomic categories. Any qualified contractor may submit a proposal, including large businesses, small businesses, and nontraditional defense contractors.
Bidders should note the NAICS code 336413, which covers manufacturing of other aircraft parts and auxiliary equipment. The Small Business Administration's size standard for this NAICS typically applies to all revenue-based eligibility determinations for small business programs—though since no set-aside is used, size status does not restrict participation here.
Given the specialized nature of NAVWAR systems and F/A-18 integration, successful bidders likely need:
- Existing security clearances or ability to obtain them (see the solicitation)
- Experience with military aerospace hardware
- Familiarity with NAVAIR's technical data packages and A-Kit provisioning processes
How to put together a competitive bid
For NAVWAR A-Kit manufacturing competitions, focus on these elements:
Technical approach: Demonstrate understanding of ECP implementation, including physical integration with F/A-18E/F airframe structures, wire routing, and interface with existing mission systems. Detail your quality management system for aerospace hardware, particularly AS9100 certification expectations.
Manufacturing capacity: Address your ability to produce precision aerospace components to military specifications, including traceability requirements for flight-critical parts. Saint Louis, Missouri has established aerospace manufacturing infrastructure; bidders should explain how their facility or supply chain leverages or connects to this ecosystem.
Past performance: Cite relevant NAVWAR, electronic warfare, or F/A-18 modification programs. Navy evaluators heavily weight demonstrated success with NAVAIR contracting processes, including CECOM/PEO-Tactical Air Programs familiarity.
Cost realism: A-Kit proposals require detailed bottoms-up estimates. Be prepared to substantiate labor rates, material costs, and learning curve assumptions for production quantities (see the solicitation for actual quantities).
Schedule compliance: ECPs typically have fleet readiness drivers. Show credible production and delivery schedules that align with NAVAIR's program milestones.
