Development history
In February 2009, Gazprom ordered two Yamal-400 type satellites from Thales Alenia Space. The satellites were name Yamal-401 and Yamal-402. Thales Alenia Space was to be responsible for all aspects of the development and building of the satellites. Both satellites were to be based on Spacebus4000C3 satellite buses.[3]
However, in 2010, Gazprom changed their satellite order so that the Yamal-401 satellite would be developed by ISS Reshetnev and be based on their Ekspress-2000 satellite bus. Thales Alenia Space would deliver the payload for Yamal-401 as originally agreed (also, no changes on the payload side of things). There were no changes with the Yamal-402 satellite, with Thales Alenia developing and building the whole satellite as originally planned.[4]
Originally, both Yamal-401 and Yamal-402 were to be launched by Ariane 5, but the launches were changed to Proton-M launch vehicles.
Launch
International Launch Services (ILS) was contracted to launch Yamal-401, using a Proton-M / Briz-M launch vehicle. The launch took place from Site 81/24 at the Baikonur Cosmodrome, at 00:16:00 UTC on 15 December 2014. The satellite was deployed into the planned geostationary transfer orbit (GTO).
