China Successfully Launches Three Shiyan 32 Test Satellites from Sea

China has once again demonstrated its advanced capabilities in space technology with the successful launch of a new group of test satellites. The mission, which took place from a sea-based platform, underscores the nation's ongoing efforts in orbital experimentation and its growing expertise in maritime space launches.

Successful Offshore Launch

On Sunday, November 9, 2025, at 5:01 a.m. Beijing Time, China successfully launched three Shiyan 32 test satellites into preset orbit. The launch was conducted from waters off the coast of Haiyang, East China's Shandong Province, utilizing a Long March 11 carrier rocket. This mission was overseen by the Taiyuan Satellite Launch Center. The successful deployment of these satellites marks the 606th flight mission of the Long March carrier rocket series.

Purpose of Shiyan 32 Satellites

The primary objective of the Shiyan 32 test satellites is to conduct experiments in space-based technologies. While official statements often describe Shiyan satellites as being for 'agricultural monitoring and space environment observation,' their classified nature suggests a broader range of experimental purposes, including 'orbital technological testing.' The 'Shiyan' program itself, meaning 'experiment' in Chinese, encompasses a variety of test satellites designed for diverse missions, from rendezvous proximity operations to Earth imaging.

Strategic Importance of Sea Launches

The launch from a sea-based platform off Haiyang highlights China's strategic development in space launch capabilities. Sea launches offer several advantages, including increased flexibility in launch trajectories and the ability to launch closer to the equator, which provides an additional boost due to Earth's rotational speed, thereby reducing fuel requirements. Haiyang has emerged as a significant hub for these maritime operations, with China having conducted its first sea launch on June 5, 2019, also using a Long March 11 rocket. This approach complements land-based launch sites and supports China's expanding commercial and experimental space endeavors.
