United Launch Alliance Successfully Completes First Operational Delta IV Heavy Launch

Nov 11, 2007, 00:00 ET from United Launch Alliance

    CAPE CANAVERAL, Fla., Nov. 11 /PRNewswire/ -- United Launch Alliance
 successfully launched the first operational Delta IV Heavy expendable
 launch vehicle for the U.S. Air Force yesterday from Space Launch
 Complex-37 Nov. 10, 8:50 p.m., EST, carrying the service's Defense Support
 Program-23 satellite. A Delta IV Heavy demonstration flight was launched
 from SLC-37 in December 2004. The launch also marks the fourth ULA mission
 conducted for the Air Force this year and the 10th ULA mission in 2007.
     Weighing 5,200 pounds, the DSP-23 satellite completed a 6 hour, 20
 minute mission and was deployed into its proper orbit at 3:10 a.m. EST,
 today. The DSP-23 launch completes the deployment of this important
 constellation of satellites. DSP satellites provide early warning for
 intercontinental ballistic missile launches and have been used by the
 military for more than 30 years.
     "Following the Delta IV Heavy test flight three years ago, the hard
 work and dedication of the team to prepare to launch our first operational
 mission was phenomenal," said Mark Wilkins, ULA vice president, Delta
 Programs. "We appreciate the support from our Air Force customer in
 achieving this milestone, and ULA is pleased to welcome the Delta IV Heavy
 as a member of our operational vehicle family."
     DSP satellites use infrared sensors to detect heat from missile and
 booster plumes against the Earth's background. Operated from the Space
 Based Infrared Systems Mission Control Station at Buckley Air Force Base,
 Colo., DSP satellites provide accurate and reliable launch detection data
 to the warfighter.
     The ULA Delta IV Heavy vehicle featured a common booster core with two,
 strap-on common booster cores. Each common booster core was powered by the
 Pratt & Whitney Rocketdyne RS-68 cryogenic engine. An RL10B-2 cryogenic
 engine, upgraded from the RL10 engine that has been in use for more than
 four decades, powered the second stage. The payload was encased by a
 5-meter diameter (16.7-foot diameter) aluminum, tri-sector payload fairing.
     ULA constructed the Delta IV launch vehicle in Decatur, Ala. By May
 2003, all three common booster cores arrived at Cape Canaveral Air Force
 Station from Decatur. The vehicle was moved from the Horizontal Integration
 Facility and erected on the stand at Pad 37 using the fixed pad erector for
 this launch June 19. Hundreds of ULA technicians, engineers and management
 worked to prepare the vehicle for the DSP-23 mission.
     ULA's next launch, currently scheduled for no earlier than Dec. 5, is
 the commercial COSMO-2 launch aboard a Delta II from Space Launch Complex 2
 at Vandenberg Air Force Base, Calif.
     ULA program management, engineering, test and mission support functions
 are headquartered in Denver, Colo. Manufacturing, assembly and integration
 operations are located at Decatur, Ala., Harlingen, Tex. and San Diego,
 Calif. Launch operations are located at Cape Canaveral Air Force Station,
 Fla., and Vandenberg Air Force Base, Calif.
