What the government is buying

The Department of the Navy, through Naval Supply Systems Command (NAVSUP) Weapon Systems Support in Mechanicsburg, is soliciting offers for wiring harnesses under solicitation number N0010427QNA45. Wiring harnesses are bundled assemblies of wires, cables, and connectors that transmit electrical power and signals in military equipment—commonly used in aircraft, ships, vehicles, and weapon systems to organize wiring, reduce vibration damage, and simplify maintenance.

NAICS code 335311 classifies this as Power, Distribution, and Specialty Transformer Manufacturing, though wiring harness production often serves as a specialized subsector within electrical equipment manufacturing for defense applications. The federal supply classification code 6150 confirms this as "Miscellaneous Electric Power and Distribution Equipment," a category that encompasses wiring harness assemblies for military platforms.

Given NAVSUP WSS's role as the Navy's primary inventory control point for aviation and maritime weapon systems, this requirement likely supports sustainment of fielded systems rather than new development. See the solicitation for specific technical requirements, quantities, and approved configurations.

Key facts

Who can bid

This is a full and open competition with no set-aside program designated. Any responsible offeror—regardless of size—may submit a bid, including large manufacturers, small businesses, and nontraditional defense contractors.

Small businesses interested in competing should verify their size standard for NAICS 335311 against the Small Business Administration's Table of Size Standards. Given the technical nature of military-grade wiring harnesses, offerors typically need capabilities in: MIL-SPEC cable assembly, precision crimping and soldering, electromagnetic shielding, environmental sealing, and quality systems certified to aerospace or military standards (such as AS9100 or ISO 9001).

How to put together a competitive bid

Understand the technical baseline. Wiring harness solicitations often reference specific military specifications (MIL-W, MIL-C, or SAE AS standards), connector families, and configuration control drawings. See the solicitation for the exact technical data package, including any first article test requirements or qualification testing.

Assess your supply chain. Critical connectors, specialty wire, and shielding materials may have long lead times or sole-source constraints. Document your sourcing plan and any proposed alternates with full equivalency data.

Price strategically. NAVSUP WSS solicitations frequently evaluate on lowest price technically acceptable (LPTA) or best value criteria. Analyze historical procurement data in SAM.gov or FPDS to understand competitive price ranges. Include all costs: engineering labor, materials, testing, packaging for military shipment, and any tooling amortization.

Demonstrate quality systems. Emphasize your quality management certification, inspection protocols, and traceability systems. Military harnesses require lot control, material certifications, and often confirmatory testing for continuity, insulation resistance, and environmental durability.

Address delivery and packaging. NAVSUP WSS requires defense-specific labeling, preservation, and packing per MIL-STD-2073. See the solicitation for required delivery schedules and shipment destinations.
