  The Titan 4B placed the IUS upper stages and DSP-1 Block 14 ballistic missile launch detection satellite. payload into a 188 km x 718 km x 28.6 deg parking orbit. The first stage of the IUS burned at 18:14 GMT and put the second stage and payload into a geosynchronous transfer orbit. The IUS second stage fired at 23:34 GMT in order to place the spacecraft in geosynchronous orbit. However, at least one connector remained attached between the stages, and the second stage motor nozzle did not extend properly. When the stage fired, the vehicle tumbled wildly during the burn. Separation of the DSP was achieved. Although it could not perform its primary mission, it did provide a good test case in that the effects of radiation on its systems could be monitored as they underwent twice-daily passages of the Van Allen Radiation Belts. However after some weeks the hydrazine propellant aboard the satellite vented into space due to a broken fuel line. It was believed this had been induced by the wild ride aboard the IUS-2 stage.

• USA 149 - . Payload: DSP-1 Block 18 F20. Mass: 2,380 kg (5,240 lb). Nation: USA. Agency: USAF. Manufacturer: TRW. Class: Surveillance. Type: Early warning satellite. Spacecraft: DSP. USAF Sat Cat: 26356 . COSPAR: 2000-024A. Apogee: 35,790 km (22,230 mi). Perigee: 35,780 km (22,230 mi). Inclination: 0.00 deg.

  DSP-1 Block 14 ballistic missile launch detection satellite. Delivered by the two-stage IUS-22 solid rocket into geostationary orbit. Fullfilled mission of DSP 19 launched in 1999 into the wrong orbit when its IUS stage failed. Still in service as of March 2007. As of 2005 Apr 2 located at 8.05E drifting at 0.166E degrees per day.

• USA 159 - . Payload: DSP-1 Block 18 F21. Mass: 2,380 kg (5,240 lb). Nation: USA. Agency: USAF. Manufacturer: TRW. Class: Surveillance. Type: Early warning satellite. Spacecraft: DSP. USAF Sat Cat: 26880 . COSPAR: 2001-033A. Apogee: 35,780 km (22,230 mi). Perigee: 35,780 km (22,230 mi). Inclination: 2.90 deg. Period: 1,435.76 min.

  Launch postponed from February, then delayed from July 27. USA 159 was a US Air Force Defense Support Program infrared missile early warning satellite was placed by the Titan core into a 328 x 663 km x 28.7 deg parking orbit. The Boeing IUS-16 upper stage then fired its first solid motor to enter geostationary transfer orbit. The second IUS solid motor fired at around 14:00 GMT placing DSP Flight 21 in near-geosynchronous orbit. Still in service as of March 2007.

• USA 176 - . Payload: DSP-1 Block 18 F22. Mass: 2,380 kg (5,240 lb). Nation: USA. Agency: NSA. Manufacturer: TRW. Class: Surveillance. Type: Early warning satellite. Spacecraft: DSP. USAF Sat Cat: 28158 . COSPAR: 2004-004A. Apogee: 36,105 km (22,434 mi). Perigee: 35,852 km (22,277 mi). Inclination: 0.68 deg. Period: 1,445.94 min.

  DSP-1 Block 14 ballistic missile launch detection satellite. Last flight of the IUS upper stage. Launch delayed from November 4, 2003, and January 17, 2003. Planned IMEX piggyback payload cancelled. Still in service as of March 2007, expected to remain operational until 2017-2022. As of 2004 Feb 15 located at 96.66W drifting at 2.464W degrees per day.
