​US Army has used up most of its long-range precision missile stockpiles in the Iran war, raising concerns over readiness for potential conflicts with China, Reuters report. Two sources said military leaders had warned Trump that stocks of systems including Patriot interceptors were falling. The news agency said it could not independently verify that figure.The pressure on stocks comes as the US defence industry attempts to increase production. Lockheed Martin, which manufactures ATACMS and PrSM, has been shifting production towards the newer PrSM as the Army phases out ATACMS. While some reports attributed the decision partly to military concerns over weapons supplies, a US official told Reuters that pressure from Gulf states was the reason he chose not to proceed.
