The F-35 has been the subject of intense scrutiny and criticism over spiraling costs, production delays and safety issues. Those concerns were aired at a November congressional hearing at which the Department of Defense said it would not offer Lockheed a multiyear contract for production of the jets until it resolved some safety issues. Amid the criticism, though, the Pentagon has continued to award large contracts for F-35 projects. In 2018 Lockheed received a $7.47 million contract to move ACURL from Fort Worth, Texas, to Eglin.
