China's Centrifugal Hypergravity and Interdisciplinary Experiment Facility (CHIEF) has launched the CHIEF1300, a hypergravity machine capable of generating over 1,200 g·tonne, surpassing the previous record held by the US Army Corps of Engineers. The CHIEF complex, located 15 meters beneath a university campus, was approved in 2021 with a budget of 2 billion yuan (US$285 million) and aims to enhance research capabilities and international collaboration.

The facility accommodates users from various sectors, including universities and industries. In conjunction with the hypergravity machine, China has also launched the Shenzhou-21 spacecraft, carrying four mice for a six-month experiment. The CHIEF1300 enables the study of physical phenomena by simulating extreme gravitational conditions, allowing researchers to analyze structural stability, such as that of a 300-meter dam using a scaled model.
