telecommunications satellite, designed and built by Lockheed Martin [NYSE:
LMT] for SES AMERICOM, was successfully launched today from Cape Canaveral
aboard a Lockheed Martin-built Atlas IIAS rocket provided by International
Launch Services (ILS).

Initial contact with the satellite, called acquisition of signal, was
confirmed at 7:53 p.m. EST from the Lockheed Martin satellite tracking
station in Uralla, Australia.

"We are extremely proud to deliver mission success for such a loyal,
long-standing customer as SES AMERICOM," said Ted Gavrilis, president,
Lockheed Martin Commercial Space Systems (LMCSS). "AMC-10 is the ninth
A2100 that Lockheed Martin has built for SES AMERICOM as part of a
successful association that spans 25 years."

AMC-10 features 24, 36 MHz C-band transponders that will be used to provide
cable television services to the 50 United States, Mexico and the Caribbean.
AMC-10 will take the place of the retiring Lockheed Martin-built Satcom C-4
at orbital location 135 degrees West Longitude and will enhance SES
AMERICOM’s world-wide fleet of satellites, which provide global distribution
of cable, broadcast television and radio, telecommunications services,
business television and broadband data.

Based on the award-winning A2100 satellite series manufactured by Lockheed
Martin Commercial Space Systems, Newtown, Pa., AMC-10 has a predicted
service life of 15 years and represents the 23rd straight successful launch
of an A2100 spacecraft for customers worldwide.

"AMC-10’s C-band payload is fully committed to the top tier cable
programmers who are depending on us to distribute dozens of channels and new
high definition services to (over 80 million) American TV households, and
we’re depending on this Lockheed Martin A2100 to perform brilliantly for the
next 15 years," said SES AMERICOM President Dean Olmstead. "Since 1996,
AMERICOM has added nine A2100 satellites to our fleet, and we look forward
to adding the tenth when we launch AMC-11 in May."

The Lockheed Martin A2100 geosynchronous spacecraft series is designed to
meet a wide variety of telecommunications needs ranging from
Ka-band/broadband services, fixed satellite services in a C-band and Ku-band
payload configuration, high-power direct broadcast services using the
Ku-band frequency spectrum, and S-band payloads. The A2100’s modular design
features a reduction in parts, simplifying construction, increasing on-orbit
reliability and reducing weight and cost.

In recognition of the A2100’s reliability, Lockheed Martin received a 2003
award for "Product of the Year," by Frost & Sullivan. Calling it "the most
reliable and efficient of its class," Frost & Sullivan recognized the
LMCSS-built A2100 satellite platform for its "outstanding on-orbit
reliability record since it was first offered in 1996."
