Question Re. SSN 688 model

schurem · 06-19-17, 03:40 AM

Hey guys, I am looking at my beautiful boat, the USS Olympia and I was wondering about two little details on her model. What are the coppery shiny surfaces on her back? Are they windows of some kind?

FPSchazly · 06-19-17, 10:12 AM

I, too, have wondered what these things are. I do not think they are windows.

Only iranian subs have windows and screen doors...

PL_Harpoon · 06-19-17, 12:39 PM

Russians have them too:

FPSchazly · 06-19-17, 12:43 PM

Yes, those windows are outside the pressure hull, though. The "ones on American subs" that we're talking about wouldn't be.

PL_Harpoon · 06-19-17, 12:46 PM

Yeah, I don't think they're windows too. What's strange is that I couldn't find any RL pictures of those things (at least not on 688 class)

EDIT.

Just found this picture:

Good find! I was curious to find out about the zinc plates.

FPSchazly · 06-19-17, 01:14 PM

Good find, indeed!

Are you talking about the sacrificial zinc anodes near the screw? They are there to prevent the brass from literally being eaten by the seawater.

Interesting tidbit of info...thanks. had no idea that was even an issue, let alone the fix.

Sacrificial zinc anodes are almost universal on all boats with metal in contact with the water. It focuses corrosion on the zincs.

I am fascinated by the zinc plates. How exactly does this work?

Does it change the chemistry of the water? How does this work while the sub is moving and water is constantly being swept away?

Colloquially knows as 'Zincs'
