The Long March 12 carrier rocket (English: Long March 12) is a new-generation medium-lift liquid-propellant carrier rocket developed by the Eighth Academy of China Aerospace Science and Technology Corporation. It is China's first 3.8-meter diameter single-core liquid rocket. The rocket adopts a two-stage configuration design, with an overall length of approximately 62 meters and a takeoff mass of 430 tons. The first stage is equipped with four YF-100K liquid oxygen/kerosene engines, and the second stage uses two YF-115 liquid oxygen/kerosene engines. It is the first to use 130-ton class pump-fed liquid oxygen kerosene engines with thrust vectoring and coal-based aviation kerosene. Its low-Earth orbit (LEO) carrying capacity is no less than 12 tons, and its 700-kilometer sun-synchronous orbit (SSO) carrying capacity is no less than 6 tons, with standard 5.2-meter and 4.2-meter diameter fairings. On November 30, 2024, the Long March 12 completed its maiden flight at the Hainan Commercial Space Launch Site, successfully launching the Satellite Internet Technology Test Satellite and Technology Test Satellite 03, achieving the first launch from China's commercial space launch site. On August 4, 2025, the second rocket (Yao-2) launch was completed, sending the Satellite Internet Low-Earth Orbit Group 07 Satellites into orbit; on November 10 of the same year, it successfully launched the Satellite Internet Low-Earth Orbit Group 13 Satellites again, marking the seventh successful launch from that site. The rocket employs the "three horizontal" testing and launching mode, overcoming challenges in aluminum-lithium alloy tanks, hold-down release, and liquid oxygen-compatible cold helium pressurization technology, achieving a launch cycle within 10 days. In September 2025, it won the Grand Prize at the 25th China International Industry Fair.
