The last USS Arizona 14-inch gun barrel begins its move from the Naval Surface Warfare Center Dahlgren Division in Virginia to Phoenix, Ariz., April 10. The gun barrel -- removed from the USS Arizona to be relined before World War II -- was at the Dahlgren Naval Proving Ground for proof testing when the attack on Pearl Harbor occurred on Dec. 7, 1941.

Tripod foremast and conning tower structure of USS Arizona after her devastating explosion. Once the fires finally burned out, a couple days after the attack, navy divers swam out to explore the wreckage. In this area was where RADM Isaac C. Kidd had commanded to his final moments (earning a posthumous Congressional Medal of Honor). Within this charred conning tower, RADM Kidd's academy ring was found... fused to a bulkhead. It was chiseled out by a diver and returned to the Kidd family.
