Gun Tub Details:

Here are the actual dimensions of the stern gun tub from the Iowa:
1) Tallest part of the shield = 56" tall
2) The lower part of the shield = 39" tall
3) Distance from the floor to the main deck = 27"
4) Distance from main deck to the tallest part of the shield = 29"
5) Distance from the knuckle to the top of the foundation floor = 15"
6) Diameter of the gun tub = 18'

The passing scuttle opening is 42" tall x 45" wide.

Dimensions from the plan:
Center of gun tub:
Distance from centerline of ship to centerline of gun tub is 14' 9"
Distance forward from AP to centerline of gun tub is 78"

Cone is 9' 9" tall to the knuckle
Knuckle is 52' 3" above baseline.

Shield info from expanded elevation drawing: (Imagine the shield laid out flat in a straight line)
Overall length of shield is 56' 2 5/16"

Step down information:
Start at AP (frame 215)
Start of step down is 83 1/8" aft of AP
Step down is 110 13/16" starting at 56" in height, ending at 39" in height
Lower part of shield is 120" long at 3' 3" in height.
Step up 110 13/16" long starting at 39", ending at 56" in height

There is the step down cut into the shield for the crew to get in and out easier.
Cut out information:
Start of cutout is 8" forward of AP

Waterline information:

Found the information about the WWII draft marks and boot topping. As close to fact as I can come up with.

This is from the Bu Ships plan 353608 / 8/18/41 / corrected working plan 5/15/43
Navy Yard, New York Plan BB616-2806AF

Measuring from the designed waterline:
Design Water Line (DWL) 34' 9 1/4"
Bow: Upper line of boot topping: 17" above DWL
Lower line of boot topping: 5' 6 1/2" below DWL

Stern: Upper line of boot topping: 17" above DWL
Lower line of boot topping: 12 1/2" below DWL


Measuring from the bottom of the hull / keel
Bow = Upper line of boot topping 36' 2 1/2" from keel / total height: 6' 10 3/4"
Stern = Upper line of boot topping 36' 2 1/2" from keel / total height: 2' 4 3/4"
(The upper line of the boot topping is parallel with the DWL/keel)

I haven't located the modernized version plan to know if there is any difference. If needed I can find out about it.

Wow, this thread is very very informative! A treasure for all building the Iowas! This will be a very good reference when I build them! :thumbs_up_1:

Thanks!
