CHARLOTTESVILLE, Virginia, October 26, 2010 - Northrop Grumman Corporation (NYSE: NOC) today announced the introduction
of a new family of X-Band Coherent Radar (XBCR) systems designed primarily
for offshore patrol vessels (OPV) and other smaller combat ship platforms.

The SeaGuard XBCR systems are being developed by Northrop Grumman's
Sperry Marine business unit, in cooperation with Australian company CEA
Technologies Pty Limited, and are expected to be available for deliveries in
early 2012.

The system's Doppler signal processing enables detection of aircraft and
helicopters at ranges of 20 nautical miles over sea or land at altitudes up
to 6,000 feet, as well as high- and slow-speed surface targets such as
rigid-hull inflatables or periscopes. It also provides superior clutter
suppression, increasing the probability of detection of small targets under
extreme weather conditions.

Multiple user-selectable operating modes provide optimum performance for
different mission requirements, such as berthing, short- or long-range
surface or air search, and periscope detection. Special navalized features
include red first strike to identify fast-moving targets, helicopter control
vectors and search-and-rescue operations.

"The affordability and performance of the XBCR system make it an ideal
replacement for magnetron-based radars in a wide range of platforms,
satisfying multiple application-specific requirements, especially in the
littoral warfare environment," said J. Nolasco DaCunha, vice president of
Northrop Grumman Sperry Marine. "The integration of proven digital
signal-processing techniques ensures consistent performance at sea and over
land, generating confidence in both the operator and platform commander. The
solid-state nature of the radar provides savings in through-life support with
a modular design developed to achieve exceptional availability, reliability
and maintainability."

CEA Technologies specializes in the design, development and manufacture
of advanced radar and communications solutions, having supplied civil and
military systems into land, maritime and air environments. The company's
product range includes phased array radar for surveillance and missile fire
control applications, integrated communications, antenna design as well as
harbor and coastal surveillance systems. The company's head office is located
in Australia's capital city of Canberra, where the majority of CEA's staff is
located. The company also has production and manufacturing facilities located
across the country and currently exports to the USA, Europe, Middle East and
Pacific regions.
