VANDENBERG AIR FORCE BASE, Calif., Oct. 5, 2001 — A Lockheed Martin-built
Titan IV B rocket successfully launched a national security payload for the
U.S. Air Force and the National Reconnaissance Office today at 2:21 p.m.
PDT. The launch was from Space Launch Complex Four East (SLC-4E) at
Vandenberg Air Force Base, Calif.

“Score another Mission Success for the U.S. Air Force/Lockheed Martin Titan
IV team,” said G. Thomas Marsh, president of Lockheed Martin Space Systems
Company-Astronautics Operations. “Thanks to all of the companies and
organizations that contribute to the Titan IV team, we can be proud of
orbiting another important national security payload for the NRO.”

This was the 33rd Titan IV launch overall. Eleven Titan IVs have been
launched from Vandenberg, 22 from Cape Canaveral Air Force Station, Fla.
Titan IV, the nation’s largest, most powerful expendable launch vehicle, is
built by Lockheed Martin Space Systems Company-Astronautics Operations in
Denver, Colo. The Titan IV B is capable of boosting payloads weighing 38,800
pounds into low-Earth polar orbit, 47,800 pounds into low-Earth equatorial
orbit, or more than 12,700 pounds into geosynchronous orbit.

This was the third Titan IV B launch this year. The earlier launches were
from Cape Canaveral including a Titan IV B flight Feb. 27, carrying a
Milstar II military communications satellite and a Titan IV B mission Aug.
6, carrying a Defense Support Program (DSP) satellite used to provide early
warning of missile launches worldwide. The next Titan IV B is scheduled for
launch in January 2002 from Cape Canaveral, Fla.
