Vitro Corporation was a major United States defense contractor which became part of BAE Systems Inc. in 1999.
This business had positioned Vitro as a ready source of uranium during US military and scientific research efforts into nuclear energy during the Second World War.
In 1978 Automation Industries and its Vitro subsidiary were acquired by General Cable Corp, which renamed the new company GK Technologies.
By the early 1990s Penn Central had begun to focus on financial services and in 1992 announced it was divesting Vitro.
