TEWKSBURY, Mass., 19 Oct. 2011. The Raytheon Co. (NYSE: RTN) Integrated Defense Systems segment in Tewksbury, Mass., has installed upgraded X- and S-band radar antennas aboard the nation's newest missile range instrumentation ship, which will aid U.S. intelligence experts with space and ballistic-missile tracking from mobile platform able to operate in all the world's oceans.The installation is part of the Cobra Judy Replacement (CJR) program, and involves massive active phased-array radar antennas, each weighing more than 500,000 pounds, Raytheon officials say. Engineers installed the antennas aboard the USNS Howard O. Lorenzen (T-AGM 25) missile range instrumentation ship, which when it enters service is scheduled to replace the USNS Observation Island (T-AGM-23).
Cobra Judy is the sea component of the U.S. Department of Defense Cobra program for monitoring missile launches and outer space. The DOD's Cobra program involves the Cobra Judy surveillance ship, as well as the Air Force Cobra Dane active electronically scanned array (AESA) radar at Eareckson Air Station, Alaska, for ballistic missile intelligence gathering; the Air Force Cobra Ball signals intelligence system aboard the RC-135S aircraft for observing ballistic missile flights at long range; and the Cobra Eye system aboard an RC-135X surveillance aircraft for tracking ballistic missile reentry vehicles.
"The Cobra Judy Replacement program marks the first shipboard integration of a true dual-band active phased-array radar suite," says Kevin Peppe, vice president of seapower capability systems at Raytheon Integrated Defense.
The CJR program is to provide long-loiter ballistic missile data collection capability. Its dual-band radar suite consists of X- and S-band phased-array sensors, a common radar suite controller, and related equipment. Now that all of CJR's mission equipment has been installed onto the ship, Raytheon starting shipboard dual-band radar integration and testing.
Raytheon is the prime contractor for the CJR mission equipment and principal on an industry team that includes Northrop Grumman Electronic Systems, General Dynamics SATCOM Technologies, VT Halter Marine, and KOS.
Work on the CJR program is primarily performed at the Raytheon IDS Surveillance and Sensors Center, Sudbury, Mass.; Northrop Grumman Electronic Systems, Baltimore, Md.; and Kiewit Offshore Services. The T-AGM 25 ship was built for the Navy by VT Halter Marine, Pascagoula, Miss.
