Raytheon to Provide Primary Sensor Payloads for Missile Defense Agency's Space Tracking and Surveillance System (STSS) program

Press Release From: Raytheon Company
Posted: Thursday, December 19, 2002

Raytheon Company is making preparations to provide the primary sensor payload for the Space Tracking and Surveillance System (STSS) missile defense system, formerly known as Space-Based Infrared System Low (SBIRS Low), to prime contractor Northrop Grumman. Both companies have signed a contract valued at approximately $200 million for the delivery of sensor payloads.

As the prime contractor for the STSS program, Northrop Grumman was previously awarded an $868 million contract from the Missile Defense Agency (MDA) to begin development of the STSS system. The contract defines the efforts associated with Block 06 of the STSS development that provide the initial space and ground segment assets.

The Raytheon STSS sensor payload was developed for the continual observation of ballistic missiles in the boost, midcourse, and reentry phases of flight. Composed of an acquisition sensor, a tracking sensor, and processing subsystem, the STSS sensor payload will provide protection from evolving threats to national security. These state-of-the-art components have successfully demonstrated performance in thermal vacuum tests against simulated targets.

"We are pleased to have been selected by the MDA-Northrop Grumman team to provide the critical spaceborne infrared payloads for the Ballistic Missile Defense System Testbed," said Stephen Nordel, Raytheon's program executive for STSS. "Our acquisition and tracking sensors will demonstrate the value of space-based IR for midcourse discrimination and counter-counter measure challenges. Our STSS payload enables a layered defense against ballistic missile threats and complements Raytheon's ground-based radars and enhances our EKV [Exo-Atmospheric Vehicle] fire control solution."

Raytheon is a leader in a broad range of missile defense technologies and initiatives, including the Exoatmospheric Kill Vehicle, the Ground-Based Radar-Prototype, X-Band Radar, Upgraded Early Warning Radar and the PAVE PAWS Early Warning Radar for the Ground-based Midcourse Defense Segment. The company also supports Sea-based Midcourse and Terminal Defense, provides the Ground-Based Radar element for the Theater High-altitude Area Defense program, and its Patriot systems continue to be mainstays for theater ballistic missile defense. Raytheon is the prime contractor and integrator for the PAC-3 system and continues to provide the Patriot Air and Missile Defense System for many U.S. and allied forces.
