AIR FORCE SAYS IUS-13 PERFORMANCE 'SUPERB'
SEATTLE, Feb. 15 /PRNewswire/ -- The U.S. Air Force has awarded Boeing (NYSE: BA) a full mission success incentive award of $800,000 for the Inertial Upper Stage (IUS) booster rocket's accuracy in delivering a NASA communication satellite to its precise target orbit 22,300 miles above Earth. On Jan. 13, the Boeing-built IUS began its second decade of launching spacecraft by successfully deploying a NASA Tracking and Data Relay Satellite (TDRS-F) from Space Shuttle Endeavour, during mission STS-54. "The performance of IUS-13 was superb," said Air Force IUS Contracting Officer Renay Campbell-Labriola, in a letter to Boeing. "The mission is considered to be a complete success, and Boeing is authorized the full mission success incentive." The IUS gave TDRS-F such an accurate boost, that only 35 pounds of the 129 pounds of spacecraft fuel was used to position TDRS-F into its final orbit. That means the spacecraft will have more fuel to maneuver in space and could enable it to operate longer than planned. The launch of TDRS-F gives NASA two fully operational satellites and a reserve satellite to meet the nation's growing demand for communication capabilities. Developed by Boeing Defense & Space Group in Seattle, the IUS is a two-stage, solid-fueled rocket that can launch spacecraft into a high Earth orbit from either the NASA space shuttle or the Air Force Titan rocket. During the past 10 years, the IUS has supported six military missions. The first IUS was launched from Cap Canaveral Air Force Base in October 1982. The 17-foot-long booster was tucked inside a Titan 34D's payload fairing along with tow military communications satellites. NASA has used the IUS boosters for each of the five sophisticated communications satellites the agency has successfully orbited. IUS also sent three interplanetary probes on their way through the solar system. Since 1982, Boeing Defense & Space Group has built 23 IUS vehicles and has a production contract to build three more for the U.S. Air Force and NASA. -0- 2/15/93 /NOTE TO EDITORS: A color photograph showing the Jan. 13 IUS deployment of TDRS-F from the Space Shuttle Endeavour cargo bay is available upon request./ /CONTACT: Cindy Naucler of Boeing, 206-773-2816/ (BA)
