Yamal 300K (Russian: Ямал-300К) is a geostationary communications satellite operated by Gazkom and built by ISS Reshetnev on the Ekspress-1000HTA plarform. 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. 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 x 72 MHz C band and 18 x 72 MHz Ku band transponders for a 36 MHz equivalent of 52 transponders. Its transmitted power is 110 W in C band and 140 in Ku band.
Yamal 300K was launched along Luch 5B November 2, 2012 at 21:04 UTC from Baikonur Site 81/23 by a Proton-M/Briz-M directly to GEO. The launch and satellite deployment was successful and Yamal 300K was commissioned into service. As of July 22, 2016 it is still in service, but has been moved to 177°E and later to 183°E.
