General Motors Co.'s military offshoot has delivered its first shipment of parts for use in missiles made by global defense powerhouse Lockheed Martin, the Dallas-based company said Thursday, Sept. 17.

GM Defense made "housing components" for Lockheed's PAC-3 Missile Segment Enhancement missiles, which are used to shoot down enemy air attacks, in 22 days. The manufacture of such parts typically takes months or years, according to Lockheed.

"Our partnership with GM Defense is a concrete example of how we’re merging world-class commercial manufacturing with defense supply chain and production practices and rapidly translating that into battlefield readiness for the United States," Lockheed Missiles and Fire Control President Tim Cahill said in a statement.

The delivery comes as President Donald Trump calls for more weapons and more factories to build them. The Pentagon earlier this year spoke with Ford CEO Jim Farley and GM CEO Mary Barra about upping the Michigan automakers' role in U.S. defense manufacturing.

“We’re proud to support production of this country’s critical defense capabilities. Our partnership with Lockheed Martin leverages GM’s precision-fabrication expertise and ability to manufacture with quality at scale. We look forward to putting these strengths to work in support of our nation's security and the people who protect it,” GM Defense President and CEO Stephen duMont said in a statement.
