Chinese orbital launch vehicle. The Long March New Generation Launch Vehicle series medium launcher would use the 3.35 m diameter module and a new 3.35 m diameter second stage as the core vehicle. Either two or four 2.25 m diameter modules would be used as strap-ons. Payload to low earth orbit would be three tonnes with two strap-ons and 10 tonnes with four strap-ons.

For geosynchronous or planetary missions the 5.0-m diameter HO fourth stage would be used. Payload to geosynchronous transfer orbit would be 1.5 tonnes with two strap-ons and six tonnes with four strap-ons. By late 2002 this version was no longer mentioned, then it re-emerged at the FAI in Bremen in 2003. However it was indicated that it had a lower priority since the payload range was covered by the existing CZ series of vehicles. Specifically it was said there was no plan to replace the CZ-2F as the launch vehicle for the Shenzhou manned spacecraft with the new series.

Number stage 0: 2. LEO Payload: 10,000 kg (22,000 lb) to a 200 km orbit at 42.00 degrees. Payload: 6,000 kg (13,200 lb) to a GTO.

Diameter: 2.25 m (7.38 ft). Span: 4.60 m (15.00 ft). Length: 25.00 m (82.00 ft). Propellants: Lox/Kerosene. No Engines: 1. Engine: YF-120t. Status: Development 2004. From top to bottom the 2.25-m Chinese new generation launch vehicle consists of a 42.3 cubic meter liquid oxygen tank, an intertank section, a 22.0 cubic meter kerosene tank, and an engine section with one gimballed LOX /Kerosene engines of 1200 kN vacuum thrust. The oxygen tank is pressurised using oxygen bled from the engine and helium is used to pressurise the kerosene tank. The engines can be throttled to 65% of rated thrust. Burn time shown assumes full thrust during engine burn.

Burn time shown assumes full thrust during engine burn.
  • Stage 3. 1 x CZ-NGLV-KO. Gross Mass: 60,000 kg (132,000 lb). Empty Mass: 7,000 kg (15,400 lb). Thrust (vac): 588.000 kN (132,187 lbf). Isp: 340 sec. Burn time: 300 sec. Diameter: 3.35 m (10.99 ft). Span: 3.35 m (10.99 ft). Length: 13.00 m (42.00 ft). Propellants: Lox/Kerosene. No Engines: 4. Status: Development 2004. Upper stage for the 3.35 m diameter core vehicle. Only information available are the types of propellants, total thrust, and number of engines. Therefore all values shown here except thrust are estimated. This launcher has a low priority since its payload capability overlaps existing Chinese launch vehicles, and it would not be developed until after 2010.
  • Stage 4. 1 x CZ-NGLV-HO. Gross Mass: 26,000 kg (57,000 lb). Empty Mass: 3,100 kg (6,800 lb). Thrust (vac): 156.000 kN (35,070 lbf). Isp: 448 sec. Burn time: 600 sec. Diameter: 3.35 m (10.99 ft). Span: 5.00 m (16.40 ft). Length: 12.00 m (39.00 ft). Propellants: Lox/LH2. No Engines: 2. Engine: YF-75. Status: Development 2004. The upper stage for the Chinese Next Generation Launch Vehicle is a modification of the CZ-3B upper stage. The stage uses a version of the Lox/LH2 YF-75 engine, simplified for improved reliability. The stage is of hammerhead form, with the upper LH2 tank with a diameter of 5 m, and the lower liquid oxygen tank with a diameter of 3.35 m. The total propellant is 22,900 kg with a burn time of over 600 seconds. Empty mass has not yet been released and is estimated.
