Topic review - Calling all USS Iowa BB-61 class fans

  Post subject:  Parorama v. Separate  Reply with quote
Let me ask another format question. There are a lot of very tight places. Would people find separate photographs like this:

or a panorama like this:

To be the better representation?

The separate photographs are clearer but the panorama gives an overview.
(Keep in mind these have been reduced greatly in size for posting here.)

Jim,

Your 3D model photos remind me of the engineering section models that were made for USS NORTH CAROLINA (BB-55) - they are displayed with the 1/96 model of the ship and are section cuts of the ship's hull showing all the various decks and machinery. Each one is mounted with a Plexiglas cover to keep "little hands" from messing with things. It's been quite a few years since I was aboard BB-55, so I'm under the impression that those are still on display.

Your 3D model is very nicely done - if there are any pumps, motors, etc. that you've left out - go ahead and add them - usually with pumps there is a flange that belongs to the pump on all inlet/outlet piping, so you could show the pump w/flanges and let it go at that (i.e. no piping). Just a suggestion!

Hank

Yes, the one shaft is at the port side. The lower level has a lot of pumps. that would then need pipes to make sense. Then there would be pipes all over.

I should add, that there will be photographs to go with this. These models are primarily to show where the photographs were taken.

I am trying to do some illustrations where I face the problem of understandability trading off against precision. The more precise I get, the more cluttered things become, and the less understandable things are.

I ask the folks here, would you consider this sufficient detail to gain an understanding of the layout of a fire room? If not, what more would you like to see?

Normally, I would use a deck plan to describe ship layout but there are thirteen levels in the fire room and I find that a 2D representation is just too confusing.

Jim,

I did Google Map the Philadelphia Navy Yard and saw where CHARLESTON is tied up. So, are they planning to sink her in a SINKEX exercise or simply sell her for scrap?



My understanding is that the means of execution has not yet been decided.

It's LKA-113. She's sitting in Philly waiting for the breakers.

Jim - isn't the USS CHARLESTON (LCS-18) a rather new ship to be scrapped? She just entered the fleet in 2019. Perhaps you mean another ship.

Or....do you mean USS CHARLESTON (LKA-113) which decommissioned in 1992? Please give details.


Response from my senator on this:

If so, I wonder if it would be possible to write someone in the Navy Dept. and see if those plans could be salvaged, etc.

Thanks,

Make it easier to re write the "history" when the archives go away.

  Post subject:  Where are the Iowa class blueprints?  Reply with quote
I'll share here.....

The original blueprints for BB-34-BB-66 were sent to the Naval Historical Warehouse in Memphis TN. That warehouse was closed and all evidence is that the contents were destroyed.

A full set of plans was sent to the Philadelphia Naval Yard (300 boxes). All of the spare parts for the Iowa class were moved to the U.S.S. Charleston and it appears the blueprints went as well.

The U.S.S. Charleston is slated to be scrapped, taking all the spare parts and blueprints to the furnace.

Perhaps you could post a link? Gong to Navsource not doing search are revealing anything fo me currently. There has been Whitehouse motions about banning old folks from using computers?

There is good information on the Type P Catapult and its operation on the NavSource online archive, "Instructions for Operation of Catapult Type P"

Thx Rick - I hadn't seen this appendix yet but very useful info!

The 5" 38 was a semi fixed shell and casing combo. The shell and casings were separate items, so my understanding was that a standard 5" 38 casing, without the shell could be used (not really a blank). When firing the 5" mounts, a noticeable burnt cork smell was noticeable as a large cork was used to plug the mouth of the cartridge. What I don't know was as the cartridge was used to generate gas pressure to activate the catapult, there would have had to have been some system to evacuate a potential cork debris buildup. A diagram showing the workings of this system would be informative.

A simple and effective system. By contrast Bismarck used a compressed air system. Some minor damage caused by one of POW's hits caused their system to become inoperable when an attempt was made to fly the Kriegstagbuch (war diary) to safety. Perhaps a subject of some disappointment to the pilot.

Shell

The type P catapult was designed by the Bureau of Ordinance. A 5-inch blank cartridge was fired into an expansion chamber that drove a piston.

The advantage of the type P was that it was entirely self-contained. It could be mounted on top of a turret without having drill holes through the turret for power or hydraulics.

Thank you R.E.D.!

I do have that book though it's not one I reference very often. I'll check that out!
