- CSIS report found the US has added 5,000 new vendors and pushed nontraditional contract obligations past $120 billion in FY 2025, but warned manufacturing lead times for vital weapons still stretch beyond 3 years.
- Pentagon committed $7.6 billion between 2025–2026 to build a rare-earth "mine-to-magnet" supply chain outside Chinese control, while seeking a defense budget request equal to 4.6% of GDP for FY 2027.
- Heritage Foundation's TIDALWAVE report warned the US faces an extreme "Triple Bind" supply failure within 25 to 120 days of conflict due to a two-year production lag, rocket motor bottlenecks, and reliance on imported Polish TNT — while China's NORINCO runs automated "smart factories" with 150%–250% wartime surge capacity.
- Seth Jones (CSIS, May 2026) estimated a Taiwan conflict alone would exhaust 3,000–5,000 JASSMs, 3,500–4,000 JASSM-ERs, and 400–1,000 Tomahawks within seven days, with Anderson and Press projecting 528 ALCMs and 120 Tomahawks for a preemptive Korean Peninsula strike.
- Hudson Institute and Stimson Center analyses warned US Pacific forward bases are unhardened and acutely vulnerable to Chinese precision strikes that could disable fuel lines, aboveground munitions storage, and runway operations within days, grounding sortie generation.
- Both nations share critical chokepoint vulnerabilities — the US remains dependent on Chinese rare earth minerals, while China's centralized rail-dependent distribution networks are uniquely susceptible to targeted cyber warfare and advanced semiconductor export sanctions.
Why it matters: The gap between announced US capacity ($120B in contracts, 5,000 new vendors, 4.6% GDP budget) and actual production timelines — over 3 years for vital weapons — means US stockpiles of JASSMs, Tomahawks, and ALCMs would be exhausted within the first week of a Taiwan conflict or within 25–120 days under the Heritage "Triple Bind" scenario, before factories can replenish them.
