3G Shielding Specialties has supplied EMI/RFI shielding for aerospace and defense electronics since 1994. From avionics line-replaceable units to radar front-ends and satellite payloads, our US-based team builds enclosure-level gaskets, board level shields and Wavexorb microwave absorbers that help programs pass MIL-STD-461 the first time.

Where 3G Shielding Is Used in Aerospace & Defense

• Avionics LRUs and cockpit displays — enclosure gasketing and board level shields for units qualified to MIL-STD-461 and RTCA/DO-160 emissions and susceptibility sections.
• Radar, EW and RF front-ends — cavity resonance absorbers to kill oscillations inside shielded modules from 1–20 GHz.
• Satellites and smallsats — lightweight multi-cavity board level shields that cut mass while isolating dense payload electronics.
• UAV / UAS platforms — thin, light low-frequency absorbers and fabric-over-foam gaskets where every gram counts.
• Ground vehicle and C4ISR systems — rugged knitted wire mesh gaskets with environmental sealing for shock, vibration and salt-fog exposure.
• Secure communications enclosures — high shielding-effectiveness gasketing for classified processing hardware.

MIL-STD Context: What Your Shielding Has to Do

Most airborne and ground-based defense programs verify electromagnetic compatibility against MIL-STD-461 (equipment-level) within a MIL-STD-464 system-level environment. Two requirements drive most shielding decisions:

• RE102 (radiated emissions) — the enclosure, its apertures and every gasketed seam determine whether internal clocks and switching noise stay inside the box.
• RS103 (radiated susceptibility) — the same shield has to keep high external field strengths from upsetting sensitive circuits.

Conductive elastomer gaskets for these programs are typically specified to MIL-DTL-83528, which defines material classes, shielding performance and environmental durability. 3G supplies conductive elastomers, fabric-over-foam and knitted wire options — and our engineers will flag galvanic-compatibility issues (for example, nickel-copper fabric against untreated aluminum flanges) before they become corrosion problems in the field.

Aerospace & Defense Shielding FAQs

Can 3G work with ITAR-controlled drawings?

Yes. 3G Shielding Specialties is ITAR registered and routinely manufactures to ITAR-controlled drawings and specifications for US defense programs.

Which gasket material is best for MIL-STD-461 RE102 compliance?

It depends on the joint. Knitted wire mesh and MIL-DTL-83528-type conductive elastomers are common for external enclosure seams; fabric-over-foam suits low-closure-force internal panels. Our engineers review your flange design, plating and environmental exposure before recommending a material.

Does 3G supply materials for satellite and space programs?

Yes. Lightweight board level shields and low-outgassing material options are available for satellite and smallsat payloads — ask an engineer about your specific environment.

How fast can we evaluate materials?

Free samples ship within 48 hours, and a sample kit can be requested online. Engineering questions are answered the same business day.
