Aug. 8 (UPI) -- The Defense Department is pressuring U.S. military contractors to produce weapons and munitions "significantly faster" as the country's stockpile dwindles due to the Iran war, it was reported Saturday.

In a memo obtained by The Washington Post, the Pentagon told industry leaders to "drive significantly faster, more aggressive delivery schedules and/or increased production for critical capabilities."

Deputy Defense Secretary Steve Feinberg said contractors have 21 days to submit plans on how they plan to achieve that.

"Years-long development cycles are not acceptable," Feinberg wrote in the Wednesday memo obtained by The Post. "We must dramatically accelerate our program schedules and expand our production capacity now."
