The nuclear-powered attack submarine Albany was launched at Newport News, Va., as former Secretary of State Henry A. Kissinger questioned President Reagan's decision for a naval buildup in the Persian Gulf. "The political leaders of the United States must define the objectives that military force can serve, and those objectives cannot be open-ended," Kissinger said. After the launching, he said that the United States should "defend freedom of navigation when it is really threatened. . . . At this moment, I do not believe there is an immediate threat to the oil supply."
