International Launch Services (ILS), a Lockheed Martin joint venture, has received authorisation from the U.S. Air Force to proceed with the launch of a military weather satellite on an Atlas V vehicle from Vandenberg Air Force Base, California, US.

The launch is scheduled for late 2007 with a spacecraft built for the Defence Meteorological Satellite Program. Both the Atlas vehicle and the satellite, known as DMSP-18, are built by Lockheed Martin.
This mission was assigned to Lockheed Martin through ILS under the Air Force's Evolved Expendable Launch Vehicle (EELV) program. This is the ninth of 16 assignments to be placed under a firm contract with go-ahead for launch.

"This will be the first flight of DMSP on Atlas V. We look forward to partnering again with our Air Force customer on an important mission that will aid and protect the men and women serving our country in all branches of the military" - Mark Albrecht, ILS President.

The Atlas V vehicle will launch in the "401" configuration, standing 57 meters tall with a 4-meter-diameter payload fairing. Atlas V vehicles in this configuration flew successfully in August 2002, May 2003 and August 2005.
DMSP spacecraft are used for strategic and tactical weather prediction to aid the U.S. military in planning operations at sea, on land and in the air. Equipped with sophisticated sensors that operate in both the visible and infrared spectra to peer through cloud cover, the satellite collects specialised meteorological, oceanographic and solar-geophysical information in all weather conditions. Since 1965, 43 Lockheed Martin-built DMSP satellites have been launched successfully by the Air Force.

Lockheed Martin has refurbished Space Launch Complex (SLC) 3-East at Vandenberg to accommodate the Atlas V vehicle. The first launch scheduled from the new pad is a mission for the National Reconnaissance Office in 2006. Launches from Vandenberg are used primarily to place satellites into low-earth, high-inclination orbits, such as polar and sun-synchronous orbits.
ILS markets and manages government and commercial missions on the Atlas V vehicle to customers worldwide. The company is headquartered in McLean, Va., a suburb of Washington, D.C.
