Yamal 204 (Russian: Ямал-204) was a geostationary communications satellite ordered by Gazkom to RSC Energia. It was to be a twin of Yamal 202 and was supposed to ride along with Yamal 203 on what would have been the third launch of the Yamal program. As a copy of Yamal 202, it would be the second iteration of the USP Bus. It would have been a 1326 kg 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 18 C band transponders to be supplied by Space Systems Loral.
