The last in a series of 14 Defense Satellite Communications System (DSCS)
spacecraft built by Lockheed Martin for the U.S. Air Force was
successfully launched today from Cape Canaveral Air Station, Fla. The DSCS
constellation supported military operations during Operation Iraqi Freedom and
will continue to provide vital communications links to U.S. and Allied Forces
around the globe well into the future.

The satellite, designated DSCS III B6, is a super high-frequency (SHF)
communications spacecraft that features Service Life Enhancement Program
(SLEP) upgrades designed to provide improved and uninterrupted secure voice
and high data rate communications to its Department of Defense users.
Additional SLEP upgrades on B6 will provide increased downlink power and
improved connectivity to its antennas. This satellite will join the 13 other
DSCS satellites on-orbit, including DSCS A3, which was launched successfully
on March 10, 2003, and already is operational.

“For over two decades, the Department of Defense has entrusted DSCS to
provide reliable, secure, communications to deployed forces around the globe,”
said Leonard F. Kwiatkowski, vice president, Lockheed Martin Space Systems in
Sunnyvale. “During this period, the system has consistently demonstrated its
capabilities, ensuring that vital information was delivered into the right
hands at the right time. We are very proud of this historic milestone and the
men and women who have contributed to the program’s tremendous legacy of

Each DSCS III satellite has a design life of 10-years, although more than
half of the DSCS satellites on-orbit today have far exceeded their design life
expectancy and continue to perform with outstanding results. Last year, the
first DSCS III satellite, A1, reached 20 years on orbit. DSCS III A1 was
launched on Oct. 30, 1982 aboard a Lockheed Martin Titan 34D launch vehicle
from Cape Canaveral.
