Yamal-300K

Yamal 300K (Russian: Ямал-300К) is a geostationary communications satellite operated by Gazkom and built by ISS Reshetnev on the Ekspress-1000HTA platform.[1] It was the first switch of satellite supplier in Yamal program after Gazkom 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 7.6 kW of power (5.6  kW for the payload) on an unpressurized bus designed for direct GEO injection with 14 years of design life. Its payload was supplied by Thales Alenia Space and is composed of 11 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 W in C band and 140  in Ku band.[6]
