The USS Iowa turret explosion occurred in the Number Two 16-inch gun turret of the United States Navy battleship USS Iowa (BB-61) on April 19, 1989. The explosion in the center gun room killed 47 of the turret's crewmen and severely damaged the gun turret itself. The first investigation into the explosion, conducted by the US Navy, concluded that one of the gun turret crew members, Clayton Hartwig, who died in the explosion, had deliberately caused it. During the investigation, numerous leaks to the media, later attributed to Navy officers and investigators, implied that Hartwig and another sailor, Kendall Truitt, had engaged in a homosexual relationship and that Hartwig had caused the explosion after their relationship had soured. In its report, however, the Navy concluded that the evidence did not show that Hartwig was homosexual but that he was suicidal and had caused the explosion with either an electronic or chemical detonator.
