The CZ-12 had its 5th launch today, a bit under 14 months since its inaugural launch.
Two YF-115 engines power the Long March 12 second stage, producing 36 tons of thrust while burning liquid oxygen and rocket-grade kerosene.
Nineteen groups of GuoWang spacecraft have been launched, with nine satellites placed into orbit on the January 19, 2026 Long March 12 flight.
Every Long March 12 launch of GuoWang has carried nine satellites per mission.
CZ-12 lifted off from Wenchang Commercial.
The Long March 12 has a payload capacity of 6,000 kilograms to a 700-kilometer sun-synchronous orbit.
Fully fueled, the Long March 12 is believed to weigh 433,000 kilograms.
A Long March 12 lifted off from Hainan at 0748 UTC on January 19, 2026, delivering the 19th group of Guowang satellites into orbit.
The Long March 12 fairing has options for 3.8-, 4.2-, or 5.2-meter diameters depending on mission needs.
Long March 12 Y5 launched SatNet LEO Group 19 from Hainan at 07:48 UTC on January 19, 2026.
The process of moving the Long March 12 from its assembly building to testing, preparations on the launch pad, and flight has been shortened to four days.
The 5th Long March 12 is slated for launch on January 19, 2026 at approximately 07:48 UTC.
Two different satellite variants are believed to be in use for the GuoWang constellation, with a larger variant launched on vehicles like the Long March 5B and smaller variants launched on rockets such as the Long March 12 and Long March 6A.
The Long March 12 has a payload capacity of 12,000 kilograms to low Earth orbit.
The Long March 12B’s development aimed to achieve equal or greater capability than the expendable Long March 12.
The 5th Long March 12 rocket is scheduled for launch on January 19, 2026 at approximately 07:48 UTC.
CALT has compatible rockets CZ-10 and CZ-12/12A.
The Long March 12 completed its maiden flight on December 12, 2025.
CALT's compatible rockets for WCLC include CZ-10B, CZ-12, CZ-12A, CZ-12B, KZ-6, HB-3, HB-3B, LJ-2, TL-3, ZQ-2, ZQ-3, XYZ-2, HY-1, and AS-1.
The GuoWang constellation includes two satellite variants, with larger ones launched on vehicles like the Long March 5B and smaller ones on the Long March 12 or Long March 6A.
