主发动机：
推力为120t的液氧/煤油（Lox/Kerosene ）发动机，或
推力为50t的液氧/液氢（Lox/LH2 ）发动机

上面级：
推力为15t的液氧/煤油发动机，或
推力为8t的液氧/液氢发动机（长3A/B/C第三级的改进型，YF75）

共有3种基本模块：
直径2.25m：1台120t Lox/Kerosene
直径3.35m: 2台120t Lox/Kerosene
直径5.0m:  2台50t Lox/LH2

整流罩直径均为5.2m。可靠性为98%，现有长征系列为91%

China's family of new generation expendable launch vehicles were announced in
February 2001, and modified descriptions were provided at the Wuzhai Air Show
and IAC in late 2002. Propulsion system details and masses were released at th
e FAI in Bremen in September 2003. Boosters of various capabilities would be a
ssembled from three modular stages of 2.25 m, 3.35 m and 5.0 m diameter. These
would be powered by new variable-thrust 120 tonne thrust Lox/Kerosene engines
or 50 tonne thrust Lox/LH2 engines as follows:

2.25 m diameter module powered by one 120 tonne thrust Lox/Kerosene engine
3.35 m diameter module powered by two 120 tonne thrust Lox/Kerosene engines
5.0 m diameter module powered by two 50 tonne thrust Lox/LH2 engines
5.0 m diameter upper stage powered by two 8 tonne thrust Lox/LH2 engines (a de
rivative of the CZ-3B upper stage)
3.35 m diameter upper stage powered by four 15 tonne thrust Lox/Kerosene engin
es, evidently an indigenous Chinese development
2.25 m diameter upper stage for the light launch vehicle (probably the CZ-4A t
hird stage)

Common large payload fairing, 5.2 m in diameter and coming in three standard l
engths.

The new launch vehicles were said to be designed for a 98% reliability as comp
ared to 91% for existing Chinese designs. They were also said to be expected t
o be 20% cheaper than existing designs. Chief Designer for the new series was
Long Lehao.

The new family would use a unique 'direct-to-pad' integration concept using hi
ghly automated systems with a total cycle time of only 20 days. The launch veh
icle was to be assembled vertically on the launch pad as soon as the stages ar
rived at the site. It would be checked out in a mobile service tower (MST). In
parallel to this the payload would be integrated and encapsulated in a separa
te encapsulation facility. The encapsulated payload was to be transferred and
mated to the launch vehicle only three days before launch.
