GuoWang small satellite platforms launched on Long March 8A and Long March 12 weigh about 695 kilograms each.
The Long March 12 has deployed nine GuoWang spacecraft per launch using a 5.2-meter-diameter fairing.
LeoLabs analysis indicates near-polar GuoWang groups launched by Long March 6A and Long March 5B are probably using the larger satellite platform while groups launched by Long March 8A and Long March 12 are probably using the smaller platform.
LeoLabs found a median radar cross section (RCS) of 3.8 square meters for GuoWang satellites launched by Long March 12.
Long March 12 (CZ-12) launches are not planned from Wenchang Spaceport due to preparations for Long March 10B (CZ-10B) at the same pad.
Two missions have taken place at Wenchang in 2026: a Long March 8A and a Long March 12.
China conducted Long March 12 and 12A launches in December 2025 from commercial spaceports.
Long March 12 Y5 launched SatNet LEO Group 19 from Hainan.
Four YF-100K engines power the Long March 12 first stage, producing a combined thrust of 510 tons while burning liquid oxygen and rocket-grade kerosene.
The Long March 12 is a two-stage launch vehicle developed by the Shanghai Academy of Spaceflight Technology whose both stages burn rocket-grade kerosene and liquid oxygen.
The Long March 12 received a small performance boost through weight savings in structures, electrical and networking cables, and various system interfaces.
The CZ-12 is more capable than the A62.
The Long March 12 Y4 launched the SatNet LEO Group 16.
Long March 12 is well into propellant loading at around T-1 hour.
The Long March 12 has only flown from the Wenchang Commercial Space Launch Site on Hainan province’s east coast to date.
A Long March 12 lifted off from Commercial Launch Pad 2 at the Wenchang Commercial Space Launch Site at 15:48 China Standard Time (07:48 UTC) on January 19, 2026, heading into low Earth orbit with a group of satellites.
China's Long March 12 Y4 lifted off from Hainan at 23:00 UTC on December 11.
The Long March 12 stands 62.6 meters tall on the launchpad and has first- and second-stage diameters of 3.8 meters.
The January 19, 2026 mission was the 5th launch of a Long March 12 vehicle.
The stock Long March 12 rocket will likely be utilized in the short term.
