CAM RANH BAY, VIETNAM - Forty-five years ago, American cargo ships filled this vast harbor, unloading supplies day after day for U.S. troops fighting the Viet Cong.
Today, the bay's azure waters are largely empty, except for local fishing boats. The once-bustling U.S. air base here, formerly home to fighter squadrons and a combat hospital, is abandoned, a reminder of the U.S. military's exit from most of Southeast Asia after the Vietnam War.
But the Pentagon is plotting a return.
Sunday, Defense Secretary Leon E. Panetta flew to Cam Ranh Bay, the first Pentagon chief to come to this deep-water port 200 miles northeast of Ho Chi Minh City since the war. He recalled "the great deal of blood that was spilled in this war on all sides -- by Americans and by Vietnamese."
He also made clear that the United States hopes difficult history will not stand in the way of a U.S. return to the sheltered anchorage off the strategically important South China Sea.
"Access for United States naval ships into this facility is a key component" of the U.S. relationship with Vietnam, "and we see the tremendous potential here," Panetta said as he stood on the stern of a gray-hulled U.S. Navy supply ship undergoing maintenance.
The vessel is one of only a few U.S. ships the Vietnamese have allowed back to Cam Ranh Bay since diplomatic ties were re-established in 1995. But it is unarmed and sails with a largely civilian crew, a requirement imposed by the Vietnamese government that has prohibited military ships from docking since 2002.
U.S. warships have called regularly at other Vietnamese ports since the guided missile frigate Vandergrift made a port call in Hanoi in 2003.
