the USS New Jersey battle ship.

Read here on the history of the USS IOWA and the tragic accident that claimed 47 lives:

H-029-4 USS Iowa Turret Explosion

I am sure there are different accounts of the facts. But regardless, so sad what happened in Turret 2 that day on 19 April 1989.
I remember this incident well. The Navy tried to blame Hartwig in an attempted CYA to cover up the disgraceful lack of training and following of safety protocols, processes and procedures. After 22 years of active service in the Navy I learned that 'big Navy' never admits fault to anything and always tries to find a scapegoat.
