On April 19, 1989 turret 2 of the USS Iowa exploded, killing 47 men. In a strange coincidence, on that same day I found myself in the turret 2 gun house of the battleship USS Missouri doing maintenance work on the small fire control computer. I had only been aboard the Missouri a short time and I was just becoming familiar with all of the fire control equipment assigned to my workcenter.
This video shows the inside of turret 2 on the Iowa and it talks about what is known about what happened that day.
Eternal rest grant unto the 47 sailors O Lord and let perpetual light shine upon them.
