The battleship USS Iowa fires its 16-inch guns during duty in the Persian Gulf on December 16, 1987. In 1943, the Iowa ferried President Franklin Roosevelt home from the Teheran Conference, where post-WW II leaders divided up the world. The ship fought battles from the South Pacific to Korea and escorted convoys through the Persian Gulf. Forty-seven sailors died atop its deck when an explosion ripped through a gun turret. Now, the new port for the retired USS Iowa just might be the home of California's annual asparagus festival, the gritty agriculture port town of Stockton on the San Joaquin River, about 80 miles inland from San Francisco.
