Bethesda, Maryland-based Lockheed Martin Corp today said that it will close plants in Arizona, Ohio, Pennsylvania and Texas, as well as four buildings in a California campus, by mid-2015, eliminating 2,000 jobs.
Another 2,000 positions will be cut in its information systems and global solutions, mission system and training and space systems units by 2014's end.
Work will be transitioned to other Lockheed plants, and some employees will move to other facilities.
