The US is prodding its defense industry to accelerate weapons production as reports of diminished stockpiles emerged recently, mainly after the protracted Iran war. The Pentagon has swung into action on this count, aiming to boost the pace of weapons production, including those depleted in the Middle East conflict, the Associated Press reported. Trump was miffed after learning that U.S. missile stockpiles had been depleted far more severely than he had believed, according to the report. Deputy Defense Secretary Steve Feinberg has written to defense industry leaders on Wednesday seeking plans to accelerate production plans. The initiative to boost defense production comes in the wake of reports that recent fighting with Iran used up more of the US military's already diminished stockpiles of advanced missile interceptors.
