Long March 7A 1.2 meters high 1:50 scale multi-part print Long March 7A Launch Vehicle China Aerospace

The Long March 7A launch vehicle (referred to as LM-7A) is a new-generation three-and-a-half-stage liquid-propellant bundled medium-lift high-orbit launch vehicle developed by the China Academy of Launch Vehicle Technology (CALT) under China Aerospace Science and Technology Corporation (CASC), using a combination of YF-100, YF-115, andYF-75 engines. With a total height of 60.1 meters and a geostationary transfer orbit (GTO) payload capacity of 7 tons, it fills a gap in China's GTO launch capability for payloads ranging from 5.5 to 7 tons. This rocket is an improvement based on the Long March 7, inheriting the third-stage modules of the Long March 3A series, adapted to a 4.2-meter fairing configuration, and capable of launching one satellite per mission and two primary satellites per mission. It primarily performs missions at the Wenchang Spacecraft Launch Site.

The rocket completed its maiden flight on March 12, 2021, successfully launching the Shiyan-9 satellite, carrying the Zhongxing-1E satellite into space on September 13, 2022, and placing the ShiJian-23 satellite and Communication Technology Test Satellite 10 into orbit on January 9 and November 3, 2023, respectively. On March 30 and May 20, 2025, it will successively execute launch missions for the Communication Technology Test Satellite 16 and Zhongxing-3B satellite. The project team continues to enhance the rocket's overall performance through technological improvements such as optimizing launch procedures, applying intelligent shutdown technology, and using new sensors.
