Türksat 4B is a Turkish communications satellite, which will be operated by Turksat.

According to the in-orbit delivery contract signed in early 2011, Mitsubishi Electric (MELCO) of Japan is in charge of the construction of the satellite's base MELCO DS2000,[1] and the American-Russian joint-venture company International Launch Services (ILS) will provide the launch of the spacecraft atop a Russian Proton-M space launch vehicle from Baikonur Cosmodrome in Kazakhstan scheduled in late 2014. In the scope of the contract, Turkish engineers will collaborate in the production of the satellite.[2][3][4][5] The production of Türksat 4B at the Mitsubishi Electric Facility in Kamakura was completed in June 2014.[6]

Türksat 4B is part of the Turksat series of satellites, and will be placed in geosynchronous orbit at 50°E to 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.[3][4][7]

Türksat 4B will have a mass of approximately 3,800 kg (8,400 lb) and an expected on-orbit life time of 15 years.[3][4]

Türksat 4A and Türksat 4B are projected to enable a capacity increase because the satellites currently in service, namely Türksat 2A and Türksat 3A, are at 90% occupied.[3][8]
