Why no periscope below 50 ft?

What about breaking it at speed?

I can see the radar mast bending pretty easily, the scope looks fairly solid.

Haven't tested this myself, but there is a speed limit for the masts with and without the fairings raised. Also, Julhelm if you're still lurking this thread: the radar masts are very high. Any particular reason for this? Your resources are what I would consider excellent so puzzled at this.

I assumed they would raise to the same height as the periscopes. Also the 50ft depth is hardcoded which gave me problems with certain boats like the Permit.

Typically radar on submarines is/was used for contact management during inbound/outbound transit. Therefore raised height wasn't very high as it didn't need to be. I understand your constraints regarding periscope depth though, particularly with the Permit as she had a much smaller sail.

I'm gonna second ETR3's descriptions - he's about as accurate as he's allowed to be, assuming his name is his actual Rate (STS1/SS myself, for the record). My guess is that they aren't using "keel depth" for their references, since when surfaced the depths are showing single digits. Makes me think they might be using center-line depth, which is just flat silly.

What strikes me as really odd is that the depths involved in PD aren't exactly hard to come by - just watch a few older submarine specials and they show the whole process.

Huh, I just assumed it was depth below keel...

Shadriss · 07-07-17, 07:39 PM

It should be... but it isn't. A 688 on the surface has a keel depth of about 26 - 30 feet, depending on how much water it has in the variable ballast tanks. In game, it shows something like 6 feet. Definitely not keel depth.

Yep that's my rate, striker turned radioman. Spent most of my time pushing sticks before ending up on ESM, WLR-8. Qualified the watch without seeing a single contact!

Then we get CSS-17 CoS on board in PH and all hell breaks loose on my watch.

CSS 17 - makes you a Bangor SSBN boy, especially paired with the WLR-8. Served on a few boats out that way, specifically the MICHIGAN (SSBN days, pre-conversion) and the ALABAMA. Nice enough area, but glad I'm done with it... I'm on terminal leave ATM, so it's all still fresh enough to be painful.

Of course, with you being a striker, that likely means you are about to be out or have been out a while yourself - haven't had those in the SS fleet in 15 years or so, as I recall.

EDIT: Just saw your signature. One of those KENTUCKY bastards. I spent more time fixing that boat when I was working for IMF... not as much as on the HMJ, of course, but a lot.
