151001-N-ZZ999-302 PACIFIC OCEAN (Feb.10, 2016) The 3-inch/50-caliber main battery of the U.S. Navy tugboat USS Conestoga (AT 54) is seen inside the shipwreck near the forecastle after the gun's support platform has fallen from its original position in front of the pilot house through the main deck. The gun was a key diagnostic artifact that served to identify the wreck as Conestoga. (U.S. Navy photo courtesy of NOAA/Released)
