G'day again,

I am getting to the paointing stage for my USS Kamehameha (BF Class) and I have doubts about the painting guide in the Mikro Mir instructions. The red oxide demarcation is depicted as halfway up the hull sides and level with the aft horizontal dive planes, but images in this thread show that the red oxide was extended higher up the hull sides, basically level with the top of the bottom section of the upper rudder if that makes sense?

Secondly, what colour should the screw be? I am thinking a goldish colour but short of brass

cheers,

Pappy

Hi Pappy,

Maybe take good look at the previous post of Vepr: note that the waterline is at the 29 ft mark on the vertical rudder. That's the top of the boot topping or the dark grey band. The boot topping itself is six feet high at most, so the top of the anti fouling (what you like to call oxide red which it isn't) is at the 23 feet mark on the rudder. That's still above the end plates on the dive planes.
Next thing: take another close look at the water line: it's not parallel to the axis of the cylindrical hull, but running lower to the right of the image. Meaning: the hull is not horizontal in the water, but lying deeper at the stern then at the bow. So to be accurate you have to look also at bow pictures, and note that the waterline lies lower on the hull sides then at the stern!

It depends how you want to depict the submarine. If you want to depict her in active service, the red antifouling paint goes halfway up the side, level with the main axis of the hull (thus level with the stern stabilizers/planes), like you described. Red paint only extended up to the waterline when the submarine was launched (some subs were launched this way, some weren't). Sometimes after an overhaul, the area between the waterline and the red paint on the lower half of the hull was painted with a mixture of black and red antifouling paint, which is sort of a dark maroon. See this photo of the Barbel:

http://navsource.org/archives/08/580/0858009.jpg

But if you're going to be depicting her in active service, the bottom half should be red and the top half should be black. I also like to make the areas on the bow where there are an acoustic windows for sonar a lighter shade than the main hull colors, but that's up to your personal preference.

As for the propeller, it was made of manganese bronze, which tarnishes to a dull yellowy-orange metallic color. But if it's fresh a brass or gold-colored paint would do just fine.

G'dsy Maartin and Justin,

Thanks very much for the great info. I am definitely going for an in service look and will be using the demarcation as suggested by Justin but i like the idea of a purple-ish boot topping. Incidentally, what would you reccomend for the red colur, it is a little closer to orange than a deep red and alittle hard to nail down?

cheers,

Pappy

I typically use a mixture of bright red with bit of rust or brown. When the red antifouling is freshly applied, it's intensely red, but over time it gets toned down to a slightly darker and browner color.

So in doing some research on the George Washington class SSBN's, I noticed that for a time, they carried "fin like projections on top and beside their missile decks. I assume that these are some form of passive sonar as they resemble smaller versions of the PUFFS arrays present on Guppy III and Tullabee. Any knowledge out there on exactly what these are?

USS George Washington: http://navsource.org/archives/08/600/0859832.jpg, http://navsource.org/archives/08/600/0859844.jpg, and http://navsource.org/archives/08/600/0859845b.jpg (November 1960, gone by June 1962)

USS Patrick Henry: http://navsource.org/archives/08/600/0859929.jpg and http://navsource.org/archives/08/600/0859913.jpg (1960-1961)

Thanks!

John

I too have been puzzled about these shark fins, and I have not been able to get a good answer as to what they are, even after asking some sailors who were on these boats in the early '60s.

When I first saw them, I had the same thought as you: PUFFS. But there are a few problems with that:

1. PUFFS needs long baselines (~100 feet) to operate, whereas these fins are closely clustered together.

2. They don't fit any of the PUFFS models: BQG-1 (original Thresher and Tullibee systems) had four arrays, BQG-2 (later Thresher, Barb, Blueback, and Sturgeon systems) had three arrays to port and three to starboard, and BQG-4 (GUPPY and later Tullibee systems) had three arrays. The number and arrangement of the fins on the 598 SSBNs is quite different to all of these.

3. They appear to be too thin to fit the PUFFS hydrophones. Even the domes of the Tullibee's BQG-1 system are thicker.

4. None of the BuShips documents I have lists PUFFS as installed or planned equipment for 598-class SSBNs.

I have a sneaking suspicion that the Ethan Allens got BQG-1 for a short period of time (see here: https://www.reddit.com/r/submarines/com ... ass_ssbns/)

My only guess is that the fins somehow were related to tests of the Polaris missile.
