The Proton booster used to launch the Türksat-4B satellite is 4.1 m (13.5 ft) in diameter along its second and third stages, with a first stage diameter of 7.4 m (24.3 ft). The overall height of the three stages of the Proton booster is 42.3 m (138.8 ft).

The Proton vehicle has a heritage of over 400 launches since 1965 and is built by Khrunichev Research and State Production Center, one of the pillars of the global space industry and the majority owner of ILS.

The satellite is based on the Mitsubishi Electric’s DS2000 platform. It sports 36 transponders and has a 2084 MHz communications capacity. It is expected to have a lengthy 30 year lifetime in orbit.

Once operating in space, the satellite will provide telecommunication 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.
