Defense & Military WireHarnesses & Cable Assemblies
Mission-critical wire harnesses engineered for ground combat vehicles, naval systems, avionics, UAV/UGV and C4ISR — M22759 wire, D38999 connectors, MIL-STD-1553 databus and EMI/EMP/TEMPEST shielding, built to MIL-STD-810 and SAE AS50881.
What makes a defense wire harness different
A defense and military wire harness has to do its job when nothing else gets a second chance — inside an armored vehicle taking ballistic shock, a fighter pulling sustained Gs, a radar array on a destroyer's mast, or a UAV operating at altitude. That means aerospace-grade M22759 PTFE/ETFE wire rated up to +260°C, MIL-DTL-27500 shielded multicore for clean signal, and connectors like D38999 and MIL-DTL-5015 with environmental backshells — not repurposed commercial cable. Every construction is built to SAE AS50881 wiring practices and IPC/WHMA-A-620 Class 3 workmanship, then validated against MIL-STD-810 environmental profiles for shock, vibration, thermal shock, humidity, salt fog and altitude.
Across a platform the harness changes job at every node: ruggedized power and weapons-station wiring in ground combat vehicles, MIL-STD-1553 / ARINC 429 / CAN databus integration for C4ISR and avionics, corrosion-resistant runs aboard ship, and EMI/EMP- and TEMPEST-controlled shielding for comms, radar and fire-control. We pair foil + braid + overall shielding with banded backshell grounding for electromagnetic hardening, and reach for shielded cable assemblies, high-temperature cable assemblies and coaxial assemblies wherever the mission demands. Quality runs under our ISO 9001 system and is built to AS9100 aerospace quality requirements, with full lot traceability and 100% electrical test on every unit.
Defense & military applications we wire
Purpose-built harnesses for every domain of modern defense systems
Ground Combat & Tactical Vehicles
Ruggedized power, signal and weapons-station harnesses for main battle tanks, infantry fighting vehicles, MRAPs and tactical wheeled platforms. Built to ride out ballistic shock, thermal extremes and continuous off-road vibration without intermittents.
Naval & Shipboard Systems
Corrosion-resistant cable assemblies for shipboard power distribution, combat-system racks, radar and sonar installations, and submarine electronics. Constructed to survive salt fog, condensation and shock loads aboard surface vessels and subs.
Military Avionics, UAV & UGV
Lightweight, high-reliability harnesses for cockpit avionics, mission computers, sensor pods, soldier-worn systems and unmanned air/ground vehicles. M22759 PTFE/ETFE wire keeps weight and bulk down while holding rating at altitude.
C4ISR, Comms, Radar & Fire-Control
RF, databus and control cable assemblies for tactical radios, satellite terminals, radar arrays, electronic-warfare suites, weapons and fire-control systems. Controlled impedance and layered shielding keep signals clean and TEMPEST-aware.
Built mil-spec, layer by layer
Conductors
Nickel- and silver-plated stranded copper sized for ampacity and weight, terminated with calibrated, force-monitored crimps to MIL-grade contacts for repeatable low-resistance joints.
Insulation
M22759 PTFE and ETFE primary wire rated to +150°C through +260°C, holding dielectric strength under high-temp, high-altitude and fluid-exposure conditions where general-purpose hook-up wire fails.
Shielding & Jacket
MIL-DTL-27500 shielded multicore with foil + braid + overall shield layers for EMI/EMP and TEMPEST control, plus abrasion-resistant jackets, convoluted conduit and heat-shrink boots for the field.
Connectors & Backshells
D38999 (MIL-DTL-38999), MIL-DTL-5015 and ARINC connectors with environmental backshells, banding and strain relief — sealed, grounded and bonded against shock, vibration and moisture ingress.
Military-grade technical capabilities
M22759 / MIL-DTL-27500 construction with D38999 connectors and EMI/EMP/TEMPEST shielding, built to SAE AS50881 and validated against MIL-STD-810 environmental profiles.

Defense wire harness FAQ
What wire and cable do you use for defense and military harnesses?
We build with M22759 (MIL-W-22759) PTFE- and ETFE-insulated aerospace wire and MIL-DTL-27500 shielded multicore cable. These constructions hold dielectric strength and mechanical integrity across a -65°C to +260°C range, at altitude, and under fuel, hydraulic-fluid and abrasion exposure where general-purpose wire degrades.
Which connectors and backshells do you terminate?
We terminate D38999 (MIL-DTL-38999) circular connectors, MIL-DTL-5015 connectors and ARINC interconnect, paired with environmental backshells, banding platforms and strain relief. Terminations are crimped on calibrated, force-monitored tooling and grounded/bonded for shielded, sealed defense assemblies.
Can you integrate MIL-STD-1553, ARINC 429 and CAN databuses?
Yes. We build harnesses to integrate MIL-STD-1553 dual-redundant databus, ARINC 429, CAN and RS-485 links, with controlled-impedance and properly shielded/terminated stubs and couplers so the bus meets its electrical requirements in the platform.
How do you handle EMI/EMP and TEMPEST requirements?
We construct foil + braid + overall shield architectures with banded backshell grounding and 360-degree shield termination for EMI/EMP-hardened and TEMPEST-aware wiring. Shielding approach is tailored to the platform requirement for C4ISR, radar, electronic-warfare and fire-control systems.
What standards do you build defense harnesses to?
We manufacture to SAE AS50881 aerospace wiring practices and MIL-STD-810 environmental requirements, with IPC/WHMA-A-620 Class 3 workmanship. Quality is run under our ISO 9001 system and built to AS9100 aerospace quality requirements. We build to these specifications rather than claiming third-party qualification of the end item.
Are your harnesses tested before they ship?
Yes — every harness gets 100% electrical test, including continuity and dielectric-withstand (Hi-Pot) checks, with crimp pull-force validation. We do not batch-sample. Environmental qualification testing to MIL-STD-810 profiles is available on request, with results documented in the delivery package.
What operating temperature and environment can the assemblies handle?
M22759 wire constructions are rated up to +260°C, and assemblies are built for high-altitude, salt-fog, humidity, shock and sustained-vibration service per MIL-STD-810 environmental profiles. Sealing, conduit and heat-shrink boots are specified to match the platform environment, from ground vehicles to shipboard and airborne systems.
What is your lead time and quantity range for defense programs?
We support prototype quantities for engineering and qualification builds, scaling to low-rate and full-rate production. Prototype harnesses typically ship in 7–10 days, with production lead times driven by connector availability and volume. Certificates of conformance and full test records accompany every delivery.
