Its payload will be supplied by Thales Alenia Space and is composed of 18 C band, 19 Ku band and 26 Ka band transponders for a 36 MHz equivalent of 52 transponders.[2] It will replace Yamal 202 on 49°E when it reaches its end of service around 2018.[4] HistoryIn 2013 Gazprom Board decided on a new plan. It required two new spacecraft: Yamal-501 and Yamal-601. In January 2014 Gazprom and Thales announced a contract for a new spacecraft, Yamal-601.[6][7] In 2015 the Yamal-401 history would repeat itself, and the contract of Yamal-601 with Thales was cancelled was assigned to ISS Reshetnev, but Thales was again allowed to keep the payload supply.[2] See also{{Portal |Spaceflight}}
