GAO: Lockheed Martin struggling to build Navy hypersonic missile at scale

The GAO reports that Lockheed Martin is struggling to scale production of Navy hypersonic missiles, currently building only half of the Pentagon's requirements due to persistent quality and manufacturing issues. Additionally, the GAO warns that the Navy and Army risk wasting time and money without a unified hypersonic missile strategy. Specifically, the Navy is approximately two years behind schedule in modernizing Zumwalt-class destroyers as part of the broader $50 billion hypersonic effort.
