USS Michael Monsoor
The Zumwalt-class guided-missile destroyer USS Michael Monsoor passes under California’s Coronado Bridge in San Diego Bay, Dec. 7, 2018. Large combat equipment such as this is often made by major defense contractors. Many small businesses, that bring new technologies to the Defense Department on their own, are also involved in the contracts to build such equipment .
