Yamal 203 (Russian: Ямал-203) was a geostationary communications satellite ordered by Gazkom to RSC Energia. It was to be a twin of Yamal 201 and was supposed to ride along with Yamal 204 on what would have been the third launch of the Yamal program. As a copy of Yamal 201, it would be the second iteration of the USP Bus.It would have been a 1,351 kg (2,978 lb) satellite with 4,080W of power (3.4 kW at end of life) on an unpressurized bus. It would have had eight SPT-70 electric thrusters by OKB Fakel for station keeping. Its payload was 9 C band and 6 Ku band transponders to be supplied by Space Systems Loral.
During 1997, even before the launch of their first satellites (Yamal 101 and Yamal 102), Gazkom 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 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.
