TEXT: DOD PRESS RELEASE ON FIRST FLIGHT OF GLOBAL HAWK

(Newest reconnaissance aircraft) (650)



Washington -- The Department of Defense announced that Global Hawk,
the department's newest reconnaissance aircraft, completed its first
flight on February 28 at Edwards Air Force Base in California. The
"high-altitude, long-endurance unmanned air vehicle" performed the
entire mission autonomously, including take-off and landing.


Global Hawk will provide military field commanders with
high-resolution, near-real-time imagery of large geographic areas,
according to DOD. "This is a key milestone towards giving warfighters
a powerful new capability," said Colonel Doug Carlson, U.S. Air Force,
program manager of the Defense Advanced Research Projects Agency,
developer of Global Hawk.

GLOBAL HAWK COMPLETES FIRST FLIGHT



Global Hawk, the Department of Defense's newest reconnaissance
aircraft, successfully flew for the first time at Edwards Air Force
Base, Calif., on Saturday, Feb. 28.


Global Hawk air vehicle number one, a high-altitude, long-endurance
unmanned air vehicle (UAV), took off from the Edwards Air Force Base
main runway at 7:43 a.m. (PST) and flew for 56 minutes. The UAV
reached altitudes up to 32,000 feet before landing on the base's main
runway. Global Hawk, with a 116-foot wingspan, navigated along a "bow
tie" track within restricted air space. The entire mission, including
the take-off and landing, was performed autonomously by the aircraft
based on its mission plan. The Launch and Recovery Element of the
system's ground segment continuously monitored the status of the
flight.


The flight was the first of numerous air worthiness evaluation and
payload demonstration flights planned. The Defense Advanced Research
Projects Agency (DARPA) is developing Global Hawk to provide military
field commanders with a high-altitude, long-endurance system that can
obtain high-resolution, near-real-time imagery of large geographic
areas.


"Today's flight was an exceptional accomplishment for the Global Hawk
team. This is a key milestone towards giving warfighters a powerful
new capability," said DARPA's program manager Col. Doug Carlson, USAF.
"Not only did Global Hawk perform beautifully, but the successful
flight demonstrated how government, military and contractor personnel
can work together on a challenging development program. I am
especially pleased with the excellent support we have received from
the Edwards Air Force Base team, and I look forward to working with
them as the program proceeds."


The new aircraft has been designed to operate with a range of 13,500
nautical miles, at altitudes up to 65,000 feet and with an endurance
of 40 hours. During a typical reconnaissance mission, the aircraft can
fly 3,000 miles to an area of interest, remain on station for 24
hours, survey an area the size of the state of Illinois (40,000 square
nautical miles), and then return 3,000 miles to its operating base.
During a typical mission, a Synthetic Aperture Radar/Moving Target
Indicator and Electro-Optical and Infrared sensors on board the
aircraft can provide near-real-time imagery of the area of interest to
the battlefield commander via world-wide satellite communication links
and the system's ground segment.


Global Hawk air vehicle number one has been located at Edwards Air
Force Base since August 1997. Air vehicle number two, which is nearing
completion, will be flown primarily to validate the performance of the
system's sensors and communication systems; its testing will begin at
Edwards Air Force Base later this year.


The Global Hawk program is managed by DARPA for the Defense Airborne
Reconnaissance Office. Teledyne Ryan Aeronautical is the prime
contractor. Principal suppliers on the contractor team include
Raytheon Systems, which is developing the ground segment and sensors;
Allison Engine Co., which builds the aircraft's turbofan engine;
Boeing North American, which builds the carbon fiber wing; and L3 Com,
which is developing the communication systems.
