ATK Composites, Clearfield, Utah, manufactured the 12-foot diameter heat
shield assembly, which surrounds the Atlas V 400 RD-180 main engine. The
company also manufactures the composite Centaur interstage adapter and
boattail, which are components on the Atlas V 500 rocket scheduled to fly for
the first time later this year. The parts are fabricated at the company’s
Utah Composites Center in Clearfield and Southern Composites Center in Iuka,

In its first mission, the Atlas V rocket successfully placed the newest
Eutelsat HOT BIRD satellite into supersynchronous transfer orbit, where it
will deliver analogue and digital television channels to viewers in Europe,
North Africa, and the Middle East.

Lockheed Martin developed the Atlas V rocket to meet the needs of the U.S.
Air Force’s Evolved Expendable Launch Vehicle (EELV) program and the growing
needs of International Launch Services (ILS) for its commercial and government
satellite customers throughout the world. ILS is a joint venture of Lockheed
Martin and the Russian firms Khrunichev and Energia.
