was planning the second generation. At that time, they planned a 24 satellites of the second generation. This extremely aggressive plan was scaled back by 2001 with a plan to launch four Yamal-200 series satellites. The first two, Yamal-201 and Yamal-202 would be launched by 2001 and the second pair, Yamal-203 and Yamal-204 by 2004. Yamal-201 and Yamal-203 would be identical and be positioned at the 90° East orbital position and Yamal-202 and Yamal-204 would also be twins and be positioned at the 49° East.

On 5 June 2014, Yamal-201 failed and the clients had to be moved to other satellites of the network. The satellite lasted 10 years and 6.5 months, short of the design life of 12 years.
