ThalesRaytheonSystems Improved Sentinel Radar Performs Successfully During
Recent Army Demonstrations
Shows higher power for greater counter rocket, artillery and mortar
capabilities

WASHINGTON, Oct. 8, 2009 /PRNewswire/ -- A ThalesRaytheonSystems (TRS)
AN/MPQ-64 Improved Sentinel Multi-Mode radar has performed successfully during
recent demonstrations held with the U.S. Army.

"The demonstrations are a positive step toward development of next-generation
radar capabilities that are critical for the Army," said Kim Kerry, chief
executive officer of ThalesRaytheonSystems, U.S. Operations. "This advanced
capability will ensure that Sentinel radar systems continue to maintain
mission-critical status in the fight against terrorism and in areas of
operation where their ability to detect and counter a variety of 21st century,
tactical threats is necessary."

In a joint initiative with the U.S. Army Cruise Missile Defense Systems
program office, TRS successfully demonstrated a version of the U.S. Army's
Sentinel air defense radar that operates at a higher power and fulfills a
variety of mission roles, including 360-degree counter rocket, artillery and
mortar capabilities. It also provides greater performance on missions against
unmanned aerial vehicles. In a modification of the U.S. Army's existing
AN/MPQ-64 Improved Sentinel, the radar increases the Sentinel baseline from
two power amplifier modules to four.

As the premier air surveillance and target acquisition-tracking sensor for the
Army's Cruise Missile Defense Systems program, the Sentinel radar's primary
mission is protecting maneuver forces and critical assets from cruise missile,
unmanned aerial vehicle and rotary and fixed-wing threats. The Sentinel
accurately acquires targets far enough forward of friendly troops to provide
sufficient reaction time for the air defense weapons to engage hostile targets
at optimum ranges.
