The US says China is building a wide range of launch methods too.China has been fielding over 600 operational nuclear warheads since mid-2024, up from about 500 last year, according to an estimate by the Pentagon.That reported growth puts Beijing on track to hit 1,000 warheads by 2030, a prediction that US defense officials made in 2021.Those findings come from the Defense Department's 2024 China Military Power Report, an annual summary of Beijing's capabilities and an assessment of its ambitions for its armed forces.The Pentagon says China isn't just making more warheads — it's building a wide array of capabilities to launch them, too."When you look at what they're trying to build here, it's a diversified nuclear force that would be comprised of systems ranging from low yield, precision strike missiles, all the way up to ICBMs with different options at basically every rung on the escalation ladder," a senior defense official told reporters at a briefing on Monday.
