TEWKSBURY, Mass., April 2, 2013 /PRNewswire/ -- The Raytheon Company (NYSE:
RTN)-led Cobra Judy Replacement (CJR) program surpassed expectations during
its first tests against a live rocket launch on March 19. From approximately
100 miles off the Florida coast, the powerful X- and S-band radars integrated
onboard the USNS Howard O. Lorenzen (T-AGM 25) successfully acquired and
tracked both stages of an Atlas V rocket launched from Cape Canaveral and
collected all associated data.


The exceptional demonstration of CJR's performance validates its mission
capability, advancing the program on schedule toward Initial Operational
Capability (IOC) in January 2014. To be deployed as a strategic, global asset
for ballistic missile monitoring, data collection and treaty verification, the
large-scale, complex dual-band radar suite of CJR consists of X- and S-band
phased-array sensors, a common radar suite controller and other related
mission equipment.

"CJR continues to excel at each stage of development and testing – no small
feat for a new program with its level of scale and complexity," said U.S. Navy
Captain Rod Wester, CJR program manager, Program Executive Office – Integrated
Warfare Systems (PEO IWS 2I). "The performance of the radars – and the
platform as a whole – has been outstanding and it is a testament to the skill,
experience and dedication of the government-industry team of experts, working
together to bring this critical capability closer to deployment."

Raytheon is the prime contractor for the CJR mission equipment and principal
on an industry team that includes Northrop Grumman Electronic Systems. The
team has been a model of collaboration, focused on the delivery of a
high-performing shipboard radar capability that the U.S. Navy, the U.S. Air
Force and the nation can rely upon as a critical global asset.

This live-launch exercise follows a series of achievements for this true
dual-band, active phased-array radar suite. Since at-sea testing began in July
2012, the program team has been incrementally testing and fine-tuning the
radars against targets of increasing complexity. In late 2012, two critical
firsts were achieved: the demonstration of full-power radiation capability of
the high-sensitivity shipboard X- and S-band radars; and the successful
dual-band acquisition and tracking of satellites under the control of the CJR
common radar suite controller.

About CJR

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. Raytheon completed the shipboard
installation of CJR mission equipment at Kiewit Offshore Services, Corpus
Christi, Texas, in October 2011, ahead of plan. The mission of the CJR program
is to provide the government with long-loiter ballistic missile data
collection capability in support of international treaty verification. CJR
replaces the original Cobra Judy, USNS Observation Island, also developed by
Raytheon and in service since 1981. CJR is planned to enter service in January
2014; the U.S. Navy will take delivery of CJR and transfer to the U.S. Air
Force for operational ownership.

Raytheon's Radar Expertise

Raytheon's skill and experience working with large-scale, active phased-array
radars spans the frequency spectrum and dates back to the original Cobra Judy
and Early Warning Radar programs -- continuing today with the advanced Dual
Band Radar, AN/TPY-2 and Cobra Judy Replacement programs.

The company has a long heritage of developing and producing some of the
world's most capable air and missile defense radars, dating back to the 1940s.
Raytheon has produced more than 1.8 million AESA (active electronically
scanned array) T/R modules to date and has decades of experience working with
adaptive beamforming technologies. Raytheon is also the industry leader in
high-performance GaN technology.
