The first liquid-propellant stage of China’s Long March 3B launch vehicle, using N2O4/UDMH propellants. Official CNSA material does not assert a narrower engine model here, so this remains an integrated stage identity.

Description
The first liquid-propellant stage of China’s Long March 3B launch vehicle, using N2O4/UDMH propellants. Official CNSA material does not assert a narrower engine model here, so this remains an integrated stage identity.
CNSA identifies CZ-3B as a three-stage launcher with N2O4/UDMH on stages 1–2, LOX/LH2 on stage 3, and four strap-on boosters; no narrower stage-1 engine model is asserted.
