Mercury Systems, Inc.
A maker of rugged electronics that process radar, electronic warfare, and other signals on military aircraft and ships, Mercury Systems builds components, modules, and full subsystems for defense primes like Lockheed Martin and RTX. It was founded in 1981 in Massachusetts as Mercury Computer Systems by engineers including Jay Bertelli. The name nods to the fleet-footed Roman messenger god Mercury—fitting for a firm centered on speed.
