Raytheon achieves critical firsts for US Navy dual-band radar
Raytheon Co. has achieved two significant milestones on the Cobra Judy Replacement program, meeting critical performance requirements to advance ongoing system integration. For the first time, the company demonstrated the full-power radiation capability with the high sensitivity CJR shipboard X- and S-Band active phased-array radars. In addition, both the X-Band and S-Band radars successfully acquired and tracked satellites under the control of the CJR common radar suite controller. Both critical firsts were realized at sea during testing onboard the USNS Howard O. Lorenzen (T-AGM 25).
"These operational successes validate the exceptional design of these radars and significantly advance our progress toward completing integration," said U.S. Navy Captain Rod Wester, CJR program manager, Program Executive Office – Integrated Warfare Systems (PEO IWS 2I). "The dedication of the

Integrated onboard this complex, mission-critical platform, the massive X- and S-Band active phased-array antennas of CJR are each approximately four stories tall and weigh more than 500,000 pounds. The mission of the CJR program is to provide the government with 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 other related mission equipment.
Work on the CJR program is primarily performed at Raytheon Integrated Defense Systems' 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
