Lockheed Martin Corporation, an advanced technology company, was formed in March 1995 with the merger of two of the world's premier technology companies, Lockheed Corporation and Martin Marietta Corporation. Headquartered in Bethesda, Md., Lockheed Martin employs nearly 130,000 people throughout the world and is engaged in the research, design, development, manufacturing and integration of advanced technology systems, products and services. As a lead systems integrator and information technology company, nearly 80 percent of Lockheed Martin's business is with the United States Department of Defense and the U.S. Federal Government Agencies. In fact, the company is one of the largest providers of information technology services, systems integration and training to the U.S. government. The remaining portion of Lockheed Martin's business is comprised of international government and some commercial sales of products, services and platforms.
