In response to dwindling stockpiles of munitions, particularly those depleted during the ongoing conflict with Iran, the US Defense Department has urged domestic defense industries to expedite production. The Pentagon's call for increased output aims to replenish its depleted arsenal and better cater to the evolving threat landscape. Deputy Defense Secretary Steve Feinberg sent letters to industry leaders on Wednesday, requesting proposals for faster delivery schedules or expanded production capacity within a 21-day timeline. The urgency stems from recent military engagements with Iran, which have further depleted the US military's stockpiles of advanced missile interceptors. Experts warn that shortages in both offensive and defensive weapons could compromise the security of US forces, as reduced inventories of Patriot and THAAD interceptors may necessitate increased risk-taking to preserve air defenses. The Department of Defense has recently signed deals with defense giants Lockheed Martin and Northrop Grumman to boost production capacity for missile defense system parts due to the scarcity of interceptors. Despite President Trump's denials, experts predict it will take at least three years to restore Patriot and THAAD interceptor stocks to pre-war levels, even with increased funding. The current defense spending bill is stalled in Congress, as lawmakers debate Trump's military actions against Iran and resist substantial increases in Pentagon spending.
