Can anyone help settle a friendly argument? One guy says that when the battleship Iowa fires all nine of its 16-inch tubes simultaneouly with the turrets aligned 90 degrees to the ship’s centerline, the ship moves sideways some distance. This guy served on Iowa, and ought to know. Another guy says no way. Even at 2,000 pounds per projo (9 tons total), the ship’s mass is so great, it would not move.
Here’s a pic that seems to show the ship moving sideways.
Any opinions? Look at the wake right at the bow (the very front of the ship) at the waterline.
