    ST. LOUIS, Feb. 14 /PRNewswire-FirstCall/ -- On the final mission for the
 program, a Boeing (NYSE:   BA) Inertial Upper Stage (IUS) payload booster
 vehicle successfully deployed a U.S. Air Force Defense Support Program (DSP)
 satellite today.
     The IUS-10 and its integrated payload, DSP-22, were launched aboard a
 Titan IV B rocket, that also flew with a Boeing-made fairing.  Liftoff
 occurred at 1:50 p.m. EST from Space Launch Complex 40 at Cape Canaveral Air
 Force Station, Fla.
     Upon separation from the rocket, IUS-10 fired its two stages to propel the
 spacecraft toward its geosynchronous orbit.  Following roll maneuvers, the IUS
 successfully deployed the spacecraft.
     "This last IUS mission added a critical asset to our nation's military
 space program with the successful launch of DSP-22," said Bill Benshoof,
 Boeing IUS program manager.  "The flight of IUS-10 concludes a 22-year journey
 for one of the most successful upper stages ever built and flown."
     The Boeing IUS program has supported national security, telecommunications
 and science missions with successful spacecraft deployments for the U.S.
 Department of Defense, the original Tracking and Data Relay Satellite
 constellation, and the Magellan, Galileo, Ulysses and Chandra missions for
     Adding to the celebration of today's successful last flight of the IUS,
 the Boeing IUS team received honors this week by the Air Force Association at
 the AFA's Air Warfare Symposium in Orlando, Fla., for its significant
 contributions to the advancement of Air Force space activities in the last 50
     The Boeing IUS has been launched from the space shuttle and Titan IV
 rockets.  There have been 24 IUS missions flown to date - 15 launched from the
 shuttle and nine launched from the Titan IV.
     A typical IUS mission launched from a Titan IV involves IUS separation
 from the rocket's second stage booster approximately nine minutes into flight.
 The IUS takes over responsibility for the remainder of the powered portion of
 the flight.
     For the next six hours and 45 minutes, the IUS autonomously performs all
 functions to place the spacecraft into its proper orbit.
     The first IUS engine burn occurs a little over one hour into the IUS
 booster's flight.  The second solid rocket motor ignites about six-and-a-half
 hours into flight followed by a coast phase, and then, separation of the
     IUS vehicle production was completed at Boeing in Kent, Wash.  Spacecraft
 integration, checkout, ground operations and launch preparation activities
 were conducted at Cape Canaveral.
     Boeing also produces the payload fairing for the Titan IV program.  A 56-
 foot long fairing was used for the DSP-22 mission.  Boeing-built fairings have
 flown on all 37 Titan IV launches to date and will fly aboard the remaining
 two Titan IV launches.
     "This successful launch continues the 100 percent mission success record
 for the Titan IV payload fairing," said Richard Peters, program manager and
 chief engineer, Boeing Titan fairing program.
     The fairing for the DSP-22 mission was produced at Boeing in Huntington
 Beach, Calif., with the fairing's thermal protection system applied at Boeing
 in Pueblo, Colo.
     The Boeing IUS and Titan fairing programs are managed by Boeing Expendable
 Launch Systems in Huntington Beach.
