EMI CHAMBER

DEPT OF DEFENSE.DEPT OF THE NAVY.NAVSEA.NAVSEA WARFARE CENTER.NSWC DAHLGREN · Response deadline: Thu, 05 Nov 2026

What the government is buying

The Naval Surface Warfare Center Dahlgen Division (NSWC Dahlgren) is seeking an Electromagnetic Interference (EMI) chamber. This falls under NAICS code 332313, which covers Plate Work and Fabricated Structural Product Manufacturing. In practice, EMI chambers are specialized enclosed structures designed to block electromagnetic interference for testing sensitive electronic equipment—common in defense and aerospace applications. These facilities require precision fabrication with conductive shielding materials, filtered power entry points, and RF-tight doors or access panels to maintain controlled electromagnetic environments.

The government released this as a Combined Synopsis/Solicitation, meaning the notice serves as both the announcement of the requirement and the formal solicitation document. No separate request for proposals is expected to follow for this procurement action.

Key facts

Who can bid

This procurement is full and open competition with no small business set-aside. Any responsible offeror—large or small business—may submit a bid. Firms in NAICS 332313 or related specialties with experience in precision metal fabrication, shielded enclosure construction, or anechoic/RF testing facilities should evaluate this opportunity.

Small businesses without cage codes or SAM registration must complete these prerequisites immediately. The deadline is tight: responses are due seven days after posting. New SAM registrants should not expect same-day activation.

How to put together a competitive bid

For fabricated structural products like EMI chambers, evaluators typically scrutinize technical specifications, past performance, and price. Prepare accordingly:

• Request specifications early. Contact the contracting officer listed on SAM.gov for any drawings, shielding effectiveness requirements, or chamber dimensions not apparent in the synopsis. EMI chambers vary enormously—anechoic versus reverberation, size from benchtop to walk-in, frequency range coverage. These details govern material selection and cost.

• Document relevant experience. Prior Navy, Army, or aerospace shielded enclosure contracts strengthen credibility. Be prepared to demonstrate understanding of MIL-STD-285, IEEE 299, or applicable test standards for shielding effectiveness verification.

• Assess subcontracting needs. If your firm lacks RF door manufacturing, ferrite tile installation, or specialized ventilation waveguide capability, identify subcontractors now and secure teaming agreements or letters of intent.

• Validate delivery feasibility. Fabricated structural products often face long lead times for specialized steel, copper, or nickel-loaded materials. Confirm supply chain capacity against any required delivery schedule—see the solicitation for specifics.

• Price strategically. Full and open competition against large defense contractors means cost realism matters. Review the commercial item determinations if applicable; defense EMI chambers often blend commercial and military-unique features.

Next steps
