Rugged Electronic Enclosures, VPX Chassis & Backplanes for Military and Defense Applications

Atrenne Computing Solutions is a leading developer of rugged computing and electronics solutions for military and aerospace applications.

We have provided mission-critical products to defense contractors and vendors for over 50 years, and our battle-proven electronic chassis enclosures and backplanes can be found in hundreds of Department of Defense (DoD) programs.

In addition to our COTS products, we also specialize in bespoke military electronics enclosure design. We have extensive experience with all military computing standards and specifications, and can create bespoke solutions that meet challenging requirements for SWaP, cooling, EMI/EMC, and more.

Military Electronics Enclosures

Mil Spec ATR Chassis

Our mil-spec ATR (Air Transport Rack) chassis are ideal for a variety of military manned and unmanned aircraft applications, including ISR (intelligence, surveillance and reconnaissance), electronic warfare, SIGINT, and radar.

A variety of architectures and form factors are supported, including SOSA VPX, OpenVPX, CompactPCI and VME. Cooling options include conduction and forced-air conduction, liquid, convection, and air-flow-through.

Small Form Factor Enclosures

Our small form factor (SFF) chassis are designed for military vehicles and platforms where space and weight are at a premium. The rugged conduction-cooled enclosures are engineered to withstand the harshest of conditions, including dust, salt, fog, extremes of temperature, and high levels of shock and vibration.

Supported architectures include Open SOSA VPX, VPX-REDI, CompactPCI and COM Express architectures. Specialized enclosures are also available that enable the use of commercial Mini-ITX systems in harsh environments.

Lab Development Chassis

We provide a range of chassis enclosures for laboratory, development and demonstration environments, designed to support engineering developers at every stage of the development-to-deployment program (D2D) lifecycle. The versatile chassis can be easily reconfigured as projects move between phases, and are ideal for flight tests and field trials.

Open-frame, portable, desktop and rackmount systems are available, with options that support 3U and 6U module form factors, air and forced-air conduction cooling, and the industry’s widest selection of backplane topologies.
