USS San Diego

The USS San Diego lies upside-down on the bottom in 110 feet of water off the coast of Fire Island, New York. She sank on July 19th 1918 in WWI most likely the victim of a mine laid by the German sub U-156. Before her demise she was actually originally commissioned as the USS California and had the illustrious distinction of serving in Teddy Roosevelt's Great White Fleet sailing around the world in a demonstration of US Naval might. During WWI, after being renamed the San Diego, she served convoy escort duty from New York to Europe. She carried a compliment of 4 eight-inch guns, 14 six-inch guns, 18 three-inch guns and two torpedo tubes. The six and three inch guns are the only ones visible today being mounted in side turrets. At over 500 feet long she makes for a spectacular dive. The images on this page were taken on a dive on July 12th, 2001 on our way back to port after diving the Andrea Doria.
