Mercury Systems
Mercury Systems (Nasdaq: MRCY) is an Andover, Massachusetts defense electronics company founded in 1981 that is a leading supplier of radiation-hardened processors, secure processing modules, and mission computing systems for defense satellite programs and space-based intelligence platforms. The company's OpenVPX-based processing architectures, secure enclave modules, and high-bandwidth RF signal processing boards are used in SIGINT (signals intelligence) satellites, EO/IR surveillance satellites, and ground-based tactical processing systems. Mercury specializes in "trusted" processing — electronics qualified for classified programs with supply chain integrity assurance and anti-tamper protection. With ~$1B revenue, Mercury occupies the critical mid-tier between defense primes (Lockheed, Northrop) and component suppliers, providing ruggedized commercial-off-the-shelf (RCOTS) processing that primes integrate into their space systems.
