China Constructs Massive Laser-Fusion Facility, Surpassing U.S. Scale

Satellite images reveal China's new research center in Mianyang, designed to advance nuclear weapons research and explore clean energy potential.

China is building a laser-ignited fusion research facility in Mianyang, estimated to be 50% larger than the U.S. National Ignition Facility (NIF).
The facility's design includes four laser bays and a central experiment chamber to fuse hydrogen isotopes, potentially aiding both energy generation and nuclear weapons research.
Experts suggest the facility could improve China's ability to design advanced nuclear weapons without explosive testing, though its broader impact remains debated.
The project mirrors the U.S.'s $3.5 billion NIF, which achieved scientific breakeven in 2022 by generating more energy from fusion than was used to initiate the reaction.
The development highlights international competition in fusion research, with implications for both energy innovation and global security dynamics.
