CZ-7 (Chang Zheng-7)

CZ-7 (Tianzhou 3) [CCTV]

The CZ-7 series of rockets is a modular launch vehicle family to replace the CZ-2, CZ-3 and CZ-4 series.

The vehicle is fueled by Kerosene and LOX and features a 3.35 m core with two YF-100 engines. The stage 2 has the same diameter and uses the same fuels. The vehicle can be augmented by two or four 2.25 m boosters, each also powered by an YF-100 engine. A cryogenic upper stage is also available for high energy orbits.

The basic CZ-7 version with four boosters was initially called CZ-2F/H.

The initial launch site is the new Wenchang Satellite Launch Center in the Hainan province. The maiden flight is planned for the end of 2015 or early 2016.
