Amid reports of depleting war munitions, the US Pentagon is reportedly pushing the country's defense industry to ramp up production of war resources as stockpiles diminish.The memo to defense industries comes after a recent study revealed the US military's declining stockpiles of Patriot and THAAD interceptors amid the ongoing conflict with Iran. (Representational/Reuters)Previous reports suggested that the country's ongoing conflict with Iran has significantly depleted the military's arms stockpiles. The White House and President Donald Trump, however, have repeatedly refuted the claims and indicated instead towards a pre-meditated need to expand defense production.Pentagon's push for munitionsPentagon spokesman Sean Parnell said in a statement on Saturday that the department was actively focused on boosting munitions acquisitions to provide "the weapons our warfighters need at the pace the threat demands."Despite confirming the efforts to boost production last week, Parnell insisted that the move was part of a larger modernisation effort within the defense industry which predated the country's ongoing war with Iran.Also Read I Iran war depleting US weapons stocks? Pentagon urges accelerated production; all you need to knowDeputy Defense Secretary Steve Feinberg wrote to industry leaders on Wednesday, setting a 21-day limit for them to submit plans to "drive significantly faster, more aggressive delivery schedules and/or increased production for critical capabilities," as revealed by a memo received by The Washington Post.“Years-long development cycles are not acceptable. We must dramatically accelerate our program schedules and expand our production capacity now," he wrote.Parnell affirmed Feinberg's memo on Saturday, adding that it “will inform the fiscal year 2028 budget submitted to Congress for funding, and it is entirely consistent with our ongoing push to rebuild the defense industrial base”, as per AP's reports.A defense spending bill has currently been stalled by the US Congress which had previously passed a resolution condemning the President's war against Iran. This has drawn opposition to the White House's request to increase Pentagon spending to USD 1.5 trillion, up from about USD 900 billion last year.Also Read I Pentagon UFO files: 5 biggest revelations from the latest declassified document dumpPatriot and THAAD interceptor stockpiles depleteThe memo to defense industries comes amid a recent study by the Centre for Strategic and International Studies (CSIS), a Washington think tank, which revealed the US military's declining stockpiles of Patriot and THAAD interceptors amid the ongoing conflict with Iran.These shrunken inventories, as per the analysis, may force the US and its Middle Eastern allies to take more risks to conserve air defences which may increase the possibility of a missile launched by Iranian forces getting through to its target.Last month, the Pentagon had struck a $58.6 billion deal with Lockheed Martin Corp, a Maryland-based defense contractor, to triple the production of Patriot interceptor missiles over the next seven years. This shift from the current annual $4.7 billion contract is expected to expand the production of Patriot missile units from 600 units to 2,000 units a year by 2030.The number of Patriot interceptors fell from 2,330 before the war to 1,030 when the April ceasefire took effect, CSIS estimated last month. Following recent fighting, the stockpile is now estimated to be between 759 and 827, a decrease of at least 65% since before the conflict started.Also Read I US-Iran war latest: JD Vance says US weighing safe Hormuz route for ships as Iran reiterates demandsThe number of THAAD interceptors fell from 452 before the war to between 232 and 262 at the start of the April ceasefire, CSIS said. The US was able to replenish some of the inventory to between 234 and 278 interceptors. But the stockpile is still at least 38 per cent smaller than it was before the conflict.President Trump, however, has consistently refuted any claims of a munition shortage in the US military, even claiming “massive amounts” of arms in a Truth Social post. He further alleged that "large amounts are being manufactured and shipped to the US as needed."
