Interestingly the photo of NJ (at Bremerton?) shows the main mast and even the stack cowl in grey. Possibly taken from the Iconic "Hammerhead Crane".

The stack cowl on the Iowa, including the boiler exhaust and the other exhaust in the aft part of the cowl, were also painted haze gray while the ship was fitting out. It appears they were repainted black, along with the main mast, when the ship went out on trial.

Yes that would be my guess! It's about the only photo I recall of a cowl in grey except for a newly launched ship I have seen.

Any one know what machineguns are placed on the small platforms on the side with the life rafts on the modern Missouri?
And if you have any better pictures of them?

Yes the Chain guns were placed on the platforms on the 01 level, but your photo shows the CIWS of which there were four. The Phalanx is a 20 mm gatling type weapon, radar controlled and firing a depleted uranium shell.

I knew the Wisconsin had chain guns but I had not seen them on the Missouri before. Does anyone know which of the Iowas had them and what specific guns? I have seen mention of both 35 and 25 mm. Where were they mounted?

Missouri had them for Operation Ernest Will in 1987. There was a shortage of these guns in the USN. They were a temporary installation and were removed so they could be installed on other ships operating in the North Arabian Sea / Persian Gulf area.

Does anyone know of any plans or photos showing the layout of the docking blocks for an Iowa class ship?

Hank has/had a copy of the docking plan for an Iowa, which he used to make a base for his 1:200 NJ.

I have it for the New Jersey.

Chuck,

PM me with your email and I'll send you a copy. Note - it is not one long plan - it's chopped up just as I got it from TFD.

Hope this helps,

Hank

Hello

I am working in some drawings for a book. I have got some questions about Missouri draft and waterline.

Attachment:

In the 80 the draft markings are more o less this, with superior waterline at 37'

But Iowa in 1943 had the waterline superior line at 36'

Seems that Missouri don´t use marks in 1945. But, was the waterline at 36' or 37'?

By the way. What was the real level in the mark?

Somewhere in this thread, in a time long long ago, this subject was discussed in some detail. As a note, I believe that the boot topping on the Iowa's (Which has moved around a bit, especially at present) tapers toward the stern and is not as wide there. The apparent reason for this is that there are much more "consumables" loaded forward and the bow will tend to rise more than the stern at a light loading. This is probably an intentional design as the hull has little volume aft below the waterline due to the tapering and shaft tunnel between the skegs.

Good luck!

I found these posts

According these data and with constant tapering:

Unless you can come up with some better data! It gets a little interesting when painting a model to incorporate the taper! I had to wedge the bow and stern variously a little when scribing the lines for the boot top.

In the original plans, the boot topping is 17" above and and 5'6-1/2" below the design waterline at the bow and 17" and 12-1/2" below at the stern.

The waterline is 34'7-1/4" above the baseline (34'9-1/4" above the bottom).

I know I found some later diagrams showing the boot topping at a later date but they are somewhere in my massive sorting stacks.

The center of buoyancy is aft of the center of the ship so there is more movement at the bow.

One reason why the draft at the front of Iowa changes much more than at the back is because of the hull form. How much draft changes when weight is added or removed is proportional to the area of the waterplane. US fast battleships had highly assymmetrical waterplane shale, with extremely blunt and fat aft section with a lot of waterplane area , and long tapering bow entrance with little waterplane Area. This is probably a major reason why Iowa class has much more variable draft in the front than in the rear.
