Military & Aerospace

Choose from an array of COTS products or partner with us to create a custom military and/or aerospace solution ideally suited to your application.

Mission Critical Military Applications

Military applications often require custom adaptations of COTS products and, for over 35 years, 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.

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.
