"CZ" = Chang Zheng (Long March) 
CZ-12B = A LOX/Kerosene 2-stage rocket with 4.37 m diameter tanks 
         and nine YF-102R first stage engines.  CZ-12B is not a 
         CZ-12 variant!  CZ-12 is 3.7 m diameter and uses four 
         YF-100K first stage engines.  CZ-12B first flew from the 
         new commercial pad at Jiquan on June 1, 2026.  Plans call 
         for first stage landing and reuse in future.  CACL 
         developed CZ-12B.
