Palantir CTO Warns U.S. Has Only 8 Days of Weapons Against China
Palantir's CTO warns America holds just eight days of munitions for a war with China — and a live conflict in Iran is burning through stockpiles that will take years to rebuild.
Shyam Sankar knows how the U.S. military fights because his company's software runs inside every major Pentagon system. That's why his warning lands so hard: America has eight days of weapons left before it runs out of ammunition in a full-scale war with China.
Sankar, chief technology officer of Palantir Technologies, delivered the stark assessment in an exclusive Fox News interview published April 3. His company's Gotham platform operates within U.S. military and intelligence agencies, giving him singular insight into the nation's defense capabilities. "We have eight days of weapons on hand for a major fight against China," Sankar told 24/7 Wall St. on March 18. "That's not deterrence. You need 800 days of weapons."
The Iran war has already put that fragility on full display. Operation Epic Fury, launched Feb. 28, saw the Pentagon fire over 2,000 munitions at nearly 2,000 targets in its first 48 hours. Payne Institute estimates show the U.S. burned through more than 6,000 defensive and offensive munitions in the conflict's first 16 days — depleting nearly 46 percent of America's ATACMS and Precision Strike Missiles inventory and nearly 40 percent of THAAD interceptors.
Replenishing those losses is not a matter of ramping up a factory. It is a matter of years. Lockheed Martin produces about 96 THAAD interceptors annually, with plans to increase to 400 per year. No THAADs have been delivered to U.S. inventory since July 2023, and the next shipment isn't expected until April 2027. Tomahawk missile production runs at about 90 per year, with an agreement to increase to more than 1,000 annually — yet replenishing the 535 Tomahawks fired in Iran would still take more than five years.
Against that backdrop, China's industrial advantage is staggering. The communist nation holds 232 times the shipbuilding capacity of the United States. One Chinese firm built more ships by tonnage in 2024 than the U.S. has constructed in the 80 years since World War II. "In the present moment, the Chinese are the best at mass production," Sankar said. "And now we look like the Germans."
Sankar argues that America has the calculus of deterrence fundamentally wrong. "The U.S. is wrong about military deterrence," he told Fox News. "America relies on the threat of its large weapons stockpiles to discourage aggression, but the real deterrent is production capacity — the ability to generate the stockpile." He described current U.S. munition usage patterns as both "precious about using them and worried about rebuilding them" — a posture that leaves the nation exposed on both ends.
Defense experts corroborate that assessment with equal urgency. "The major risk is not that we're going to run out for this war, but that the inventories are inadequate for a possible conflict with China," said Mark Cancian, a CSIS senior advisor and retired Marine colonel. "THAAD is probably the worst in terms of depletion. We didn't have a large inventory to begin with, and between what we shot last year and what we've shot so far this year, we may have shot half the inventory."
The geography of a potential next conflict makes those numbers even more sobering. Lt. Col. Jahara "Franky" Matisek of the Payne Institute and U.S. Northern Command warned that South China Sea scenarios expose the vulnerability most acutely. "A South China Sea crisis is exactly the kind of scenario where long-range strike and high-end air/missile defense become decisive quickly," Matisek said. "It's not looking good."
President Donald Trump's rhetoric of a "virtually unlimited supply" of munitions collides with that industrial reality. While the administration announced agreements to "quadruple" production of key systems, those increases remain years from materializing. Patriot PAC-3 missile production runs at about 600 per year, with a new deal to increase to 2,000 annually over seven years. Precision Strike Missile production could reach 390 per year, but Lockheed Martin's announced "quadrupling" agreement has yet to translate into actual production increases.
Sankar argues that artificial intelligence integration in defense production offers the only viable path forward — and that the answer is not simply copying China's model at home. "We're not going to re-industrialize symmetrically," he said. "We're not just going to take the things they're doing as they're doing them and bring them here. No, we're going to do them in entirely different ways that help us close the business case on bringing all of these capabilities in production back home."
The strategic stakes extend well beyond the current stockpile shortfall. China has been planning its military buildup since the first Gulf War, and the Iran war hands Beijing real-time intelligence on U.S. military performance and stockpile vulnerabilities. Every munition expended in the Middle East is one China does not have to destroy — it simply watches, learns, and waits.
Sen. Roger Wicker, chair of the Senate Armed Services Committee, acknowledged the problem during a March 24 hearing. "Our defense industrial base has struggled to keep pace," Wicker said, noting that the U.S. deploys $4 million Patriot interceptors to shoot down Iranian drones costing a fraction of that price. That mismatch between expenditure and production capacity is what Sankar calls an "undeclared emergency" — one that could decide the next great power conflict before a single shot is officially fired.
