Satellite Images Reveal China's Accelerating Nuclear Program Expansion

• New satellite imagery shows significant expansion at several nuclear-related facilities in southwest China, indicating an acceleration in modernizing and enlarging its nuclear arsenal.
• At Zitong, engineers have added bunkers, reinforced ramparts, and new secured structures, with experts suggesting parts of the site may be used for testing high explosives for nuclear warheads.
• The Pingtong site's design is consistent with facilities manufacturing plutonium "pits," featuring a 360-foot ventilation stack and ongoing refurbishment.
• Upgrades across multiple nuclear locations have accelerated since 2019, signaling rapid growth in China's nuclear capabilities.
• China's nuclear expansion challenges global arms control efforts, as Beijing shows no interest in joining new agreements, while the US estimates its warhead count could reach 1,000 by 2030.
