President Donald Trump has invoked the Defense Production Act to address constraints in weapons supply and development for munitions production and supply chains, according to a memo made public on Tuesday.

“I hereby find that conditions exist which may pose a direct threat to the national defense or its preparedness programs,” Trump said in a June 11 memorandum to the Pentagon chief.

He cited “limited production capacity, fragile supply chains, long-lead dependencies, and related production bottlenecks.”
