Description
The four strap-on booster units of China’s Long March 3B launch vehicle. CNSA documents four boosters in the CZ-3B architecture but does not publish a narrower booster engine model in the cited page, so this remains an integrated booster identity.
CNSA identifies CZ-3B as a three-stage launcher with four strap-on boosters and N2O4/UDMH propulsion for the first and second stages; no narrower booster model is asserted.
