Turksat 4B satellite was made by Mitsubishi Electric Corp. (МЕLCO) based on DS200 platform. Weighting 4,924kg, it will provide telecommunications and direct TV broadcasting services over a wide geographic region between west of China and east of England, spanning Turkey, as well as Europe, Central Asia, the Middle East and Africa.

“This is the second ILS Proton launch for Mitsubishi Electric and Turksat, following the launch of Turksat 4A in February of last year. It has been an honor to be entrusted with these important satellites and to ensure their safe delivery to orbit. The teams at Mitsubishi Electric, Turksat, Khrunichev, and ILS are to be commended for their tireless work and dedication.” Kirk Pysher, President of the International Launch Services

Turksat 4B is a multi-band satellite with an expected on-orbit maneuver lifespan of 30 years. From its position of 50° East at geostationary Earth orbit it will provide high flexibility of switchability and connectivity among different service areas to its customers.
