Yamal-300K (Russian: Ямал-300К) is a geostationary communications satellite operated by Gazprom Space Systems and built by ISS Reshetnev on the Ekspress-1000 satellite bus.[1] It was the first switch of satellite supplier in Yamal programme after Gazprom had disagreements on the schedule and cost of Yamal-301 and Yamal-302 with RSC Energia.[2][3] It is a 1,870 kg (4,120 lb) satellite with 5.6 kW of power on an unpressurized bus designed for direct geostationary orbit injection with 14 years of design life. Its payload was supplied by Thales Alenia Space and is composed of 8 x 72 MHz C-band and 18 x 72 MHz Ku-band transponders for a 36 MHz equivalent of 52 transponders.[4][5] Its transmitted power is 110 watts in C-band and 140 watts in Ku-band.[6]
