Advanced EHF is the next generation of protected military satellite communications satellites and provides vastly improved global, survivable, highly secure, protected communications for strategic command and tactical military personnel operating on ground, sea and air platforms. AEHF also serves international partners including Canada, the Netherlands and the United Kingdom.

COM DEV is under contract to Northrop Grumman Aerospace Systems, to supply six flight sets of electromechanical switches, passive microwave filters and Beam Select Switch assemblies. Beam Select Switch assemblies provide high-speed switching, selectable attenuation and filters that reject undesired signals and provide the ability to adjust the level of the transmitted signals.

The fifth and sixth flight sets of AEHF hardware are currently in production at COM DEV's facilities at Cambridge, Ontario and Aylesbury, U.K. The AEHF team includes the U.S. Air Force, Lockheed Martin Space Systems Company in Sunnyvale, California, as the AEHF prime contractor, space and ground segments provider as well as system integrator, with Northrop Grumman Aerospace Systems in Redondo Beach, California, as the payload provider.
