the second dual launch of the Yamal programme and the second iteration of the USP Bus. It was a satellite with 4,080 watts of power (3.4 kW at end of life) on an unpressurized bus. It had eight SPT-70 electric thrusters by OKB Fakel for station keeping. Its payload was 9 C-band and 6 Ku-band transponders supplied by Space Systems/Loral.

), Gazprom Space Systems 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
