Model: Commercial Titan 3. Year: 1990. Family: Titan. Country: USA.

Commercial version of Titan 34D military booster. It differed in having a lengthened second stage and a 4 m diameter payload shroud to handle shuttle-class or Ariane-type dual payloads.

The design originated as the losing Martin submission for the USAF Medium Launch Vehicle competition (which was awarded to Douglas for their Delta 7000 series in January 1987). However commercial buyers had already booked flights on the booster in September 1986. Availability was however restricted due to renovaton of Cape Canaveral pad 40 from July 1990 to 1992.

1990 March 14 - 11:52 GMT - Launch Site: Cape Canaveral. Launch Complex: LC40. Launch Pad: LC40. Launch Vehicle: Titan 34D. Model: Commercial Titan 3. LV Configuration: Commercial Titan 3 CT-2. FAILURE: Second stage failed to separate due to a wiring error in the stage separation electronics, stranding the payload in low earth orbit.
  • Intelsat 6 F-3 Nation: International. Program: Intelsat. Payload: Intelsat 603 / Orbus-21S. Mass: 4,215 kg (9,292 lb). Class: Communications. Spacecraft: HS 393. Agency: INTELSAT. Perigee: 35,786 km (22,236 mi). Apogee: 35,790 km (22,230 mi). Inclination: 0.00 deg. Period: 1,436.20 min. COSPAR: 1990-021A. USAF Sat Cat: 20523. 38 C-band and 10 Ku-band transponders. Placed in unusable low earth orbit after second stage separation failure. In May 1992 shuttle STS-49 snared the satellite, and in three EVA's the crew attached a new perigee boost motor, which then reboosted the satellite to geosynchrounous orbit. Positioned at 34 deg W in 1992-1997; 24 deg W in 1997-2001. Later assigned to Intelsat spin-off New Skies, which positioned it at 340º East, from where it provided C-band coverage of the entire Atlantic region, including virtually all of Latin America, Europe, Africa, the Middle East, and the eastern half of North America. As an inclined orbit satellite, IS-603 was best suited for voice/data trunking and video contribution, but could also be used for carrier-scale IP services, notably network bridging and expansion. It supplemented the prime Atlantic region coverage provided by the station-kept NSS 7 satellite, located at 338º East. As of 2007 Mar 11 located at 19.96W drifting at 0.012W degrees per day.References: 1, 2, 5, 6.
