Northrop Grumman’s Space Park campus in Redondo Beach, California, is a space-systems engineering and manufacturing site. Current Northrop Grumman material describes high-volume production of proliferated low-Earth-orbit tracking and transport-layer satellites, protected military satellite-communications work including the COOLR programme, and a Space Park microelectronics foundry that designs and manufactures III-V compound semiconductors and microwave and millimetre-wave integrated circuits. The campus also supports civil and national-security spacecraft, payloads, sensors and other integrated space systems.
