China is undergoing a significant expansion of its nuclear arsenal and infrastructure. Initial reports identified the construction of approximately 320 suspected intercontinental ballistic missile (ICBM) silos across three primary sites near Yumen, Hami, and Yulin. These silos are spread across several thousand square kilometers to complicate neutralization efforts, posing challenges to United States military strategies.

Satellite imagery and expert analysis now reveal that this expansion has extended to at least seven secretive sites, including Pingtong, Zitong, Lop Nur, Jiuquan, Mianyang, Jinta, and Guangyuan. These facilities are linked to nuclear warhead production, weapons research, explosive testing, and nuclear-material processing. At the Pingtong site in central China, analysts suggest the complex may be used to produce plutonium pits, which are essential components for nuclear warheads. At Lop Nur, the site of China’s first nuclear test, recent activity includes new tunnels and support facilities. Construction activities involve the development of entire towns, staff depots, and specialized equipment.

The Pentagon estimates China’s stockpile was approximately 620 warheads in early 2026, with projections suggesting the nation could possess more than 1,000 by 2030 and potentially 1,500 by 2035. While China maintains a “no-first-use” policy and calls for nuclear non-proliferation, the scale of these developments represents a major long-term investment in its nuclear capabilities.
