Defense and aerospace giant Lockheed Martin Corp. of Bethesda, Md., is trying to drum up U.S. government interest in a system that would defend American territory against missiles launched from ships lurking offshore. The U.S. Department of Defense is deploying a rudimentary system to protect the nation against intercontinental ballistic missiles (ICBMs), but there is no program under way to guard against sea-based threats. With approximately 20,000 kilometers of coastline, the United States is highly vulnerable to such an attack, according to David Kier, Lockheed Martin vice president and managing director of protection systems. Approximately 75 percent of the U.S. population and 75 percent of U.S. military bases are located within 322 kilometers of a coast, putting them within range of missiles fired from offshore, Kier told reporters at a July 28 luncheon at the National Press Club here.
