Yamal-401 (russian: Ямал-401) is a Russian
geostationary communications satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth ...

Ku-band
The Ku band () is the portion of the electromagnetic spectrum in the microwave range of frequencies from 12 to 18 gigahertz (GHz). The symbol is short for "K-under" (originally german: Kurz-unten), because it is the lower part of the ori ...
transponders
In telecommunications, a transponder is a device that, upon receiving a signal, emits a different signal in response. The term is a blend of ''transmitter'' and ''responder''.

Development history
In February 2009, Gazprom ordered two Yamal-400 type satellites from
Thales Alenia Space
Thales Alenia Space () is a Franco-Italian aerospace manufacturer. A joint venture between the French technology corporation Thales Group (67%) and Italian defense conglomerate Leonardo (33%), the company is the largest satellite manufactur ...
. The satellites were name Yamal-401 and
Yamal-402
Yamal-402 ( Russian: ) is a Russian geostationary communications satellite. It was launched on 8 December 2012, 13:13:43 UTC from Site 200/39 at the Baikonur Cosmodrome in Kazakhstan. It was built by Thales Alenia Space, and is based on the ...
. 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.
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.
Originally, both Yamal-401 and Yamal-402 were to be launched by
Ariane 5, but the launches were changed to
