Decomissioned ship USS O'Brien sunk by USS Lake Erie (CG-70) and HMCS Vancouver (FFH-331) with 5" guns. (The ex-O'Brien had all of it's doors either removed or welded open to ensure a quick sinking.) Even before the shoot multiple bombs and harpoon missiles were fired at it. There WAS a foward mast and a bridge prior to the attack. All video was taken from a US Navy helicopter ...it's amazing how much it takes to sink such a ship even with the doors welded open!
