Missile Defense. Raytheon is building the sensor payload. Additionally, the El Segundo site is the company center of excellence for the development and production of laser products. Raytheon company's Navy Multiband Terminal (NMT) is the first advanced, next-generation satellite communications (SATCOM) system to successfully log on to and communicate with the U.S. government's Milstar SATCOM system using low and medium data rate waveforms. The system provides naval commanders and sailors with greater data capacity, as well as improved protection against enemy intercept and jamming. Visible Infrared Imaging Radiometer Suite (VIIRS), was developed by Raytheon Space and Airborne Sensors and is currently in operation on the Suomi NPP satellite. Future deliveries of VIIRS will fly onboard JPSS to continue the operational space based climate and weather sensing legacy of the MODIS sensors. Communications Raytheon's Universal Control System (UCS) is an unmanned aerial system (UAS) "cockpit" that improves operator awareness and efficiency, while providing the ability to control multiple unmanned aircraft, and reduce potential accidents. The company also makes several software radio and digital communication systems for military applications such as Cooperative Engagement Capability (CEC), is participating in Navy-Marine Corps Intranet (NMCI), ECHELON and the Joint Tactical Terminal (JTT) programs. Digital Multimedia Watchdog, a tool used by the FBI to record phone calls and Internet communications. Radioactive materials detection system As part of the company's growing homeland security business and strategic focus, Raytheon has teamed with other contractors to develop an Advance Spectroscopic Portal (ASP) to allow border officials to view and identify radioactive materials in vehicles and shipping containers more effectively. Semiconductors Raytheon also manufactures semiconductors for the electronics industry in sites in the US and UK. In the late 20th century it produced a wide range of integrated circuits and other components, but as of 2003 its US semiconductor business specializes in gallium arsenide (GaAs) components for radio communications as well as infrared detectors. It is also making efforts to develop gallium nitride (GaN) components for next-generation radars and radios. The UK arm specialized in CMOS on silicon carbide (SiC) development and foundry work but is no longer taking on new orders, having been on the premises for 57 years. Missile defense systems In the framework of Ground-Based Midcourse Defense, Raytheon is developing a Ground Based Interceptor (GBI) that includes a booster missile and a kinetic Exoatmospheric Kill Vehicle (EKV), along with several key radar components, such as the Sea-Based
