In 2013, Gazprom Space Systems Board decided on a new plan. It required two new spacecraft: Yamal-501 and Yamal-601.[6] In January 2014, Gazprom and Thales announced a contract for a new spacecraft, Yamal-601.[7][1] In 2015, the Yamal-401 history would repeat itself, and the contract of Yamal-601 with Thales was cancelled and was reassigned to ISS Reshetnev, but Thales was again allowed to keep the payload supply. However, in 2016, this decision to give the spacecraft bus development contract to ISS Reshetnev was reversed, and Thales Alenia Space ended up developing and building the whole satellite, bus and payload.[7][8]
Launch
The satellite was launched on 30 May 2019, at 17:42:00 UTC.[9] On 24 June 2019, the satellite was inserted into nominal geostationary orbit.[10]
Mission
The satellite is intended for the replacement of the Yamal-202 satellite and business development in the Ka-band. On 19 July 2019, the satellite was finally put into operation, transferring all the networks from the Yamal-202 satellite to it.[1]
