4 stage vehicle consisting of 1 x 8S810 + 1 x 8S811 + 1 x 8S812 + 1 x Briz-M

Family: orbital launch vehicle. Country: Russia. Engines: RD-253-14D14, 17D58E, S5.98M. Spacecraft: Raduga, Gorizont, Glonass, Spacebus 3000. Projects: Americom. Launch Sites: Baikonur, Baikonur LC81/24, Baikonur LC200/39. Stages: Proton K-2, Proton K-3, Proton M-1, Proton KM-4 Briz M. Agency: Chelomei bureau.



1999 July 5 - . 13:32 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton/Briz K/M. FAILURE: Second stage explosion.. Failed Stage: 2.
  • Raduga - . Payload: Raduga s/n 45L. Mass: 1,954 kg (4,307 lb). Nation: Russia. Agency: RVSN. Class: Communications. Type: Military communications satellite. Spacecraft Bus: KAUR-3. Spacecraft: Raduga. Apogee: 30 km (18 mi).

    Carried a Russian Defence Ministry communications satellite. First attempted flight of the Khrunichev Briz-M upper stage in place of the usual Block DM. After the second stage explosion the remainder of the vehicle survived for 45 seconds before breaking up. Debris landed near Karaganda. As a result of this accident the Kazakh government suspended launches from Baikonur pending Russian agreement to pay back part of rent owed.


2000 June 6 - . 02:59 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton/Briz K/M.
  • Gorizont - . Payload: Gorizont 45. Mass: 2,125 kg (4,684 lb). Nation: Russia. Agency: Svyaz. Manufacturer: Reshetnev bureau. Class: Communications. Type: Civilian communications satellite. Spacecraft Bus: KAUR-3. Spacecraft: Gorizont. Completed Operations Date: 2000-06-06 . USAF Sat Cat: 26372 . COSPAR: 2000-029A. Apogee: 35,798 km (22,243 mi). Perigee: 35,779 km (22,231 mi). Inclination: 0.3000 deg. Period: 1,436.20 min.

    Communications satellite. First successful Proton/Briz-M launch. The Proton placed the Briz-M/Gorizont payload stack into a suborbital trajectory. The stage then performed four maneuvers to put the satellite into geosynchronous orbit:

    • Burn 1 placed the stack into a 200 km, 51.6 deg parking orbit probably inclined at around 51.6
    • Burn 2 raised apogee to 6000 km and changed inclination slightly
    • Burn 3, at second perigee, four hours after launch put the stack in a 369 x 34,988 km x 48.8 deg transfer orbit. The Briz-M then jettisoned its empty toroidal supplementary fuel tank.
    • Burn 4, ten hours after launch, placed Gorizont No. 45L in near-geostationary orbit.

    Gorizont No. 45L was expected to be the final launch of that model of television broadcasting satellite. It carried 6 C-band transponders, one L-band, and one Ku-band transponder. The newer Ekspress satellites are replacing the system. Stationed at 145 deg E. Positioned in geosynchronous orbit at 145 deg E in 2000. As of 5 September 2001 located at 145.25 deg E drifting at 0.002 deg W per day. As of 2007 Mar 10 located at 144.69E drifting at 0.019W degrees per day.

2003 June 6 - . 22:15 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC200/39. LV Family: Proton. Launch Vehicle: Proton/Briz K/M.
  • AMC-9 - . Payload: Spacebus 3000B3. Mass: 4,100 kg (9,000 lb). Nation: USA. Agency: SES Americom. Manufacturer: Cannes. Program: Americom. Class: Communications. Type: Civilian communications satellite. Spacecraft Bus: Spacebus 3000. Spacecraft: Spacebus 3000. USAF Sat Cat: 27820 . COSPAR: 2003-024A. Apogee: 35,796 km (22,242 mi). Perigee: 35,778 km (22,231 mi). Inclination: 0.0000 deg. Period: 1,436.10 min.

    Launch delayed from December 2002, then to February 10, 2003, then to February 28, March 15, April 28 and May 19. Finally moved forward from June 12 and 7. Upper stage changed from DM3 after several failures. The fifth burn of the Briz-M upper stage placed the spacecraft in a geostationary transfer orbit of 6,445 km x 35,674 km x 17.2 deg. The satellite used its own engine to place itself in geosynchronous orbit at apogee. Alcatel Spacebus 3000B3 with C and Ku band communications for North America from a geotationary position of 72 deg W. Americom at the time of launch had become a subsidiary of Societe Europeene des Satellites (SES), Luxembourg, which operated the European Astra satellie constellation. As of 2007 Mar 10 located at 83.02W drifting at 0.008W degrees per day.


2003 December 10 - . 17:42 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC81/24. LV Family: Proton. Launch Vehicle: Proton/Briz K/M.
