Mission Critical Military Applications

Sealevel specializes in rugged hardware designed to withstand environmental challenges including hazardous locations, shock & vibration, and temperature extremes. With COM architecture, the connectors are mounted directly to the carrier board, eliminating cable connections and enabling maximum reliability. COM modules are available with a -40°C to +85°C operating temperature change, allowing for fanless operation. Sealevel has exceeded our defense customers’ expectations. We have consistently provided innovative hardware and software products enabling computer connectivity and control to every major US and Allied military contractor including Northrop Grumman, Raytheon, BAE, Boeing, L3Harris, General Dynamics, NAVWAR, NAVAIR and SOCOM.

Sealevel delivers proven, COTS, mission-ready products and customized solutions for advanced systems, achieved by leveraging over 35 years of engineering and manufacturing experience serving military, government, and commercial customers. From complex laptop docking stations to high-speed communication adapters, Sealevel’s electrical and mechanical design expertise delivers unparalleled performance while meeting stringent MIL-STDs. 

Some of our most rewarding projects have been in partnership with military contractors. We’ve designed interfaces to allow communication between various devices – across different branches of service, computers that exceed military standards for temperature and vibration and more.
