What the government is buying
NAVSUP Weapon Systems Support Philadelphia is soliciting for a control interlock for Department of the Navy use. Control interlocks are safety-critical mechanical or electromechanical devices that prevent equipment from operating unless certain conditions are met—commonly used in weapons systems, aircraft, shipboard machinery, and other defense platforms to ensure safe sequencing and prevent hazardous operations.
This procurement falls under NAICS 336413: Other Aircraft Parts and Auxiliary Equipment Manufacturing, indicating the item supports military aircraft or related aerospace systems rather than general industrial applications.

Who can bid
This procurement is full and open competition with no small business set-aside. Any responsible offeror—large or small business, including original equipment manufacturers (OEMs), aerospace/component specialists, and qualified distributors—may submit a bid.
Small businesses in NAICS 336413 should note the size standard for this industry to confirm eligibility for any future socioeconomic programs; see the solicitation for applicable thresholds. Firms without existing defense contracting experience should verify whether Defense Federal Acquisition Regulation Supplement (DFARS) clauses apply and whether they meet any qualification requirements for aerospace-grade components, such as:
- AS9100 quality management certification (common for aviation work)
- NADCAP accreditation for special processes (if applicable)
- ITAR registration for defense articles
How to put together a competitive bid
For aircraft parts manufacturing, bidders should prioritize:
Technical data package compliance: NAVSUP WSS procurements typically require strict adherence to military specifications (MIL-STD, MIL-SPEC) or OEM drawings. Request the complete technical data package early; deviations often require pre-approval.
Traceability and counterfeit prevention: DFARS 252.246-7007 and related clauses govern counterfeit electronic parts; physical interlocks require material/certification traceability. Document your supply chain controls explicitly.
Source of supply verification: NAVSUP WSS frequently manages items with diminishing manufacturing sources. Propose alternative or cross-referenced part numbers only if the solicitation permits; otherwise, provide exact-item capability.
Past performance documentation: Include relevant Navy, Air Force, or other DoD contracts for similar interlock/control components. OEM-approved supplier status strengthens competitiveness.
Pricing structure: Given no set-aside, expect competition from established defense contractors. Review Federal Supply Class 1680 (Aircraft Miscellaneous Components) pricing histories in FPDS or GSA databases if available; analyze should-cost for specialized machining, assembly, and testing.
Small business subcontracting plan: Required if offeror is other than small business and the contract exceeds the applicable threshold.
