Associated space launch
The Ekspress series spacecraft for Data transmission, TV & radio-broadcasting, communications, Internet, video-conference closely resembled the Gals spacecraft and shared a similar spacecraft bus. Ekspress was to replace the widely used Gorizont spacecraft, and plans called for deployments at 13 locations (40 degrees, 53 degrees, 80 degrees, 90 degrees, 96.5 degrees, 99 degrees, 103 degrees, 140 degrees, 145 degrees, 205 degrees, 322.5 degrees, 346 degrees, and 349 degrees, all East longitude) for domestic needs and to support the Intersputnik Telecommunications Association.
SL-12 R/B(2) was lifted into orbit during the mission ‘Proton-K/DM-2M | Ekspress 2’, on board a Proton-K/DM-2M space rocket.
The launch took place on Sept. 26, 1996, 5:50 p.m. from 200/39 (200L).
