Observation Scope?

[thegreattriscuit]

Just a quick piece of curiosity that maybe some of the more experienced/knowledgable may be able to help me with...

I've discovered that the observation periscope (with it's wide field of view and ability to look straight up) can be used to almost exploitive effect to avoid depth charges.... in most situations you can literally watch the mean people as they run past you and dump them into the water from your vantage point anywhere from 30 to 120 meters below... and as long as you've got enough juice left, you can easily throw the telegraph up to 'flank', and get out of the way...

I've also used this tactic (exploit?) to more perfectly time my "jump back to the service and plug him with a torpedo, for being such a turd".

Is this a legitimate and/or historic tactic at all, or am I being cheap? The primary concern that *I* would have is that I'm not sure if the Scopes were designed to be used at depth (I should think 30 meters or so would be fine... 140m+ would seem risky at best to my uneducated self)...

Any thoughts?

To answer your question without going into a long winded explanation.

It would be totally unrealistic. OB Peri was used to look for planes.

Are you playing vanilla SH3 or are you useing one of the Supermod addons with it ?

I think I read somewhere that the submarines could have been built much sturdier and more able to dive deeper, but that the periscopes were a weak spot that could not be solved. My guess is that your tactic is historically incorrect, but maybe someone with more knowledge about submarines can confirm this.

I'm running "stock" gwx, if there is such a thing... haven't even looked in JSGME, yet... for I hear there be dragons...

in any case, you're probably right... but I'm not sure if that's going to stop me from doing it anyways . the depth charges look like deadly tinsle

Water is too dark and murky to see very far with a periscope, and the seals on them aren't strong enough to handle being raised at any great depth.

Actually, there be no dragons. JSGME is the greatest addition to game play ever.
When you get around to installing mods, you MUST use this. It is easy IF YOU READ THE ******* MANUAL!!!
If you encounter any problems, there are many here who will help you.
SH3 without mods is like a honneymoon without a wife (or husband, depending upon your sex preference).
Welcome aboard.

Shameless postcount bump.

Don't worry. Be happy with JSGME. You're missing out if you don't use any of the huge selections of mods out there produced by many talented modders. JSGME makes it a breeze to enable/disable mods.

As far as the scope goes-
Not only will it leak at depth and the water is too dark, I doubt the hoist would be strong enough to raise it at depth as well. There's alot of sea pressure pressing down on the scope that the hoist has to overcome. Lowering it, if you could get it up , will be a problem too. The hoist might not provide enough braking action against the pressure and the scope may slam down due to the pressure.

I don't know if u-boats had a hydraulic lift for the scopes or an electric motor. I believe US fleet boats used hydraulics to raise/lower scopes.

Hydraulic pumps powered by electric motors.

Apparently they were originally electric, hydraulic lifts being introduced in later boats.

You mean like after everything else fails or before you start?

(Sorry, couldn't resist - rhetorical question, no need to reply).

There actually should not be much water pressure along the axis of the periscope - most of it would be trying to compress the scope inwards towards its axis.

But the word around here is:

1) You would historically be limited to speeds under like 5 knots or it could break off/bend your periscope.

2) You could not see far underwater through the periscope.

3) The seals, while fine when operating statically at depth, would probably not tolerate operating dynamically, that is, with the periscope moving up and down and twisting, at very much depth.

The current SH3 fix by h.sie and stiebler makes the periscopes worthless above about 5 knots; you also can't raise it either.
A bit of realism that was really needed.

I've heard about this h.sie fix... i think I'll google it for my next career. Changing the rules mid-patrol feels... wrong somehow :P

No need to Google, you can find it right here:

H.sie and Stiebler have done some great work with the promise of even more to come.

Well worth it. The periscope fix that h.sie came up with is perfect. Your periscope blurs if you go a little too fast and is unusable if you are going too fast. No more running around at flank speed while submerged and looking through your scope.

There are other fixes as well like no more kicking the WO out of bed when you surface. Now he gets his butt out of bed himself and goes up to the bridge automatically.
