The satellites entered their designated orbit, continuing the phased deployment of China\u2019s satellite internet system and marking the 671st mission of the Long March rocket family.<\/p>\n<div style=\"width: 100%;max-width: 989px;margin: 0 auto;aspect-ratio: 16 \/ 9\"><iframe style=\"width: 100%;height: 100%;border: 0\" src=\"https:\/\/www.youtube.com\/embed\/pHMdZ0LVIuQ\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/div>\n<p>A commercial-launch subsidiary of China Aerospace Science and Technology Corporation served as the launch-services prime contractor. The Long March 12 was developed under the leadership of the Shanghai Academy of Spaceflight Technology, also known as CASC\u2019s Eighth Academy.<\/p>\n<p>The October 10 mission was the ninth launch of the standard Long March 12 configuration since the vehicle\u2019s debut in November 2024. CASC did not disclose the number of satellites aboard the rocket, their individual mass or configuration, the target orbit\u2019s altitude and inclination, or when the spacecraft are expected to enter operational service. The designation \u201c27th group\u201d refers to the deployment batch rather than the number of satellites carried.<\/p>\n<p>The flight extended a rapid sequence of numbered satellite internet deployments from Hainan. A Long March 12 launched the 24th group on August 16 and the 25th group on September 17, followed by a Long March 8A carrying the 26th group on September 23. Four consecutive groups were therefore deployed within 55 days, using three Long March 12 missions and one Long March 8A flight.<\/p>\n<h2>Long March 12 Supports Multi-Satellite Deployment<\/h2>\n<p>The Long March 12 is a two-stage liquid-propellant launch vehicle approximately 62 meters long. Its 3.8-meter core places it in China\u2019s 4-meter-class launcher category, making it the country\u2019s first single-core vehicle in that diameter class.<\/p>\n<p>The rocket\u2019s first stage uses four liquid oxygen-kerosene engines, each producing approximately 1,250 kilonewtons of thrust. CASC rates the vehicle to carry at least 12 metric tons to low Earth orbit or at least 6 metric tons to a 700-kilometer sun-synchronous orbit. These figures describe the launcher\u2019s overall performance and do not indicate the orbit used for the October 10 payload, which was not disclosed.<\/p>\n<p>Mission planners can select either a 4.2-meter- or 5.2-meter-diameter payload fairing, providing flexibility for single spacecraft, multi-satellite stacks and missions targeting different orbits. Fairing volume is particularly important for constellation launches because deployment adapters and separation systems must be accommodated alongside the satellites.<\/p>\n<p>The Long March 12 uses horizontal assembly, horizontal testing and horizontal transfer to the launch area. This ground-processing model is suited to repeat launch operations and the higher mission cadence required for large satellite constellations.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-90528 size-full\" src=\"\/wp-content\/uploads\/2026\/10\/Long-March-12-Rocket-in-Transit.webp\" alt=\"Long March 12 Rocket in Transit\" width=\"1080\" height=\"719\" srcset=\"\/blog\/wp-content\/uploads\/2026\/10\/Long-March-12-Rocket-in-Transit.webp 1080w, \/blog\/wp-content\/uploads\/2026\/10\/Long-March-12-Rocket-in-Transit-300x200.webp 300w, \/blog\/wp-content\/uploads\/2026\/10\/Long-March-12-Rocket-in-Transit-1024x682.webp 1024w, \/blog\/wp-content\/uploads\/2026\/10\/Long-March-12-Rocket-in-Transit-768x511.webp 768w\" sizes=\"(max-width: 1080px) 100vw, 1080px\" \/><\/p>\n<p><em>Long March 12 Rocket in Transit<\/em><\/p>\n<p>The rocket completed its maiden flight on November 30, 2024, during the first launch conducted from the Hainan Commercial Space Launch Site, China\u2019s first launch complex dedicated to commercial missions.
