Raytheon Adapts Common Ground System to KillerBee(R) Unmanned Aircraft System

Open, non-proprietary ground system provides best long-term capability

PARIS, June 16, 2009 /PRNewswire/ -- Raytheon Company (NYSE: RTN) has tested a
proven, open- software architecture unmanned ground system that enables one
ground station to control multiple KillerBee Unmanned Aircraft Systems (UAS).

"We have taken a ground system, which is a variant of the U.S. Navy's Tactical
Control System, and adapted it to a Linux operating system to make it hardware
independent and fully scalable," said Mark Bigham, Raytheon Intelligence and
Information Systems business development director. "Our Small Tactical
Unmanned Aircraft Systems (STUAS) ground station solution is aligned with the
Office of the Secretary of Defense's path for a common ground system
capability, reducing training costs and controlling multiple air vehicles."

In a recent demonstration, Raytheon controlled the KillerBee aircraft while
simultaneously providing a manned, anti-tank guided weapon target information
from the aircraft. This significantly shortens the kill chain by leveraging
the bird's-eye view from the KillerBee to pass target-marking information to
the shooter on the ground, such as a soldier equipped with a Javelin anti-tank
guided weapon. Cross-cueing provides the soldier a machine-to-machine data
transfer to mark the direction to a potential target for possible use in a
busy urban terrain.

The Raytheon team has developed and tested a number of new capabilities,
including adapting full control of three electro-optical infrared laser
sensors, full control of all phases of flight, including landing and takeoff,
plus several other significant new features, applications and integrations.
System features include running the flight system on a laptop control and the
ability to run the hardware on a platform-agnostic Linux-based operating
system.

"The ground system can be flown using either a joystick or a game pad
controller used by many gaming enthusiasts today," Bigham added. "Furthermore,
it provides the Navy and Marine Corps with the first open Universal Control
System, capable of flying KillerBee, MQ-8 Fire Scout and other UASs
simultaneously."

The TCS variant ground system will be compatible with the U.S. Marine Corps
Combat Operations Center, as well as being common to both a shipboard- and
land-based systems.

KillerBee is designed to provide the Navy and Marine Corps with a UAS for
their respective STUAS and Tier II missions, which require UAS launch and
recovery aboard a ship. KillerBee is ideally suited for force protection in an
expeditionary environment and represents a major upgrade to today's embedded
airborne surveillance, reconnaissance and target acquisition capability.
