PHOTO: An overhead view of the battleship USS IOWA (BB-61) firing all 15 of its guns (nine 16-inch and six 5-inch) during a target exercise near Vieques Island. Careful observation of the three main turrets shows the barrels in various states of recoil.
The USS Iowa saw action in World War 2 and the Korean War. She was reactivated in 1984 as part of the 600-ship Navy. In April 1989, an explosion in her No. 2 gun turret killed 47 sailors. The USS Iowa was decommissioned for the last time in 1990.
