==Turret explosion==

On 19 April 1989 while conducting gunnery excersizes in the Atlantic, an explosion of undetermined cause ripped through her number two sixteen-inch gun turret killing 47 crewmen.  Within weeks blame for the incident centered on Gunners Mate 2nd-Class Clayton Hartwig, the gun captain of Turret Two's center gun, who the Navy stated was suicidal and depressed following the breakup of an alleged homosexual affair with another sailor [http://www.nytimes.com/1990/05/27/us/their-hearts-said-navy-erred-about-iowa-blast.html].  Despite vehement denials from the Hartwig family and many others, the Navy stuck by its "official" version of the explosion until Congress forced the Navy to conduct tests on the 16-inch powder bags used in the firing of ''Iowa's'' big guns.  At Sandia National Laboratories, New Mexico and the Naval Surface Warfare Center at Dahlgren, Virginia, drop tests were done on several powder bags from a height of fifteen feet, simulating the approximate speed of what was suspected by critics of the Naval investigation to be the prime cause of the explosion: an over-ram into the gun's breech as the powder was mechanically inserted.  The resulting test explosions caused the Chief of Naval Operations, Admiral Frank B. Kelso III, to publicly apologize to the Hartwig family and state there was no proof that Hartwig caused the explosion.
