Observation Periscope

mangaroca · 05-17-07, 03:45 AM

Hi All,

I am wondering what it is for? It has smaller ocular magnitude... The only purpose I came up with is that after destruction of the attack scope we (the Germans during WWII) can/could use a secondary device. However, whay weren't the U-boots given two IDENTICAL X8 (X10 in GWX) SCOPES!?

The second thing is an idea.
When at periscope depth, with observation periscope extended and with at least one officer (prefferably the Watch Officer) in the Control Room the command (normaly available only on the surface) "NEAREST VISUAL TARGET" be available? Could THIS be modded?

What do You say?

from my reading i've found the observation or "sky" periscope had a much larger head lense than the attack periscope - it was for navigation purposes and for actually viewing the sky - i'm assuming for weather reporting.

Well, thats what I'm saying! Let's makethe obs. scope work under the water! In my opinion the Watch officer could be using it just as well as the Captain so the command "Nearest Visual Contact" should be available...

Ummmm, the OBS scope does work when submerged. In two ways, first you can use it for mine detection & secondly, if you are at the Attack Scope and you raise the OBS scope too you will get better NAV MAP updates, whether it be planes or ships. However, it is not possible to have your NO or WO give you audible responses. (hardcode <sigh>)

^^ ooh thanks danlisa, didnt know that about the observation scope.

I shall stick it up more often now

I forgot.

Another thing to consider is to have the OBS scope up when snorkeling at TC. It will give you the much needed warning if you are about to be attacked by aircraft.

The attack periscope has a blind spot i.e. immediately above the u-boat. The observation scope largly covers this blind spot and is therefore better at spotting approaching aircraft. I gathered this information from a book I am reading at the moment 'U333 The Story of a U-boat Ace' by Peter Cremer.

Be careful you don't do yourself an injury

First off, the attack periscope wasn't x8, it was x1.5 and x6, while the observation 'scope was x1 and x4. The purpose was to observe, or look for targets while submerged, which is why it's in the control room for easy access. The smaller resolution gave it a wider field of view, and the larger head and lens let in more light, which made it much better at night.

Also useful if you are playing SHCMR with malfunctions enabled, being too lazy to stress test your boat just out of port, and then find your attack scope all blurry when you get to DH99

Here is the difference - all in line with what has been commented above

Very good! Thank you, vedrand; and in case I missed you, WELCOME ABOARD!!!

From me to vedrand, never seen that pic before

danlisa · 05-18-07, 07:13 AM

:hmm: Strikes me that the 'glass' on both those scopes looks really crap.

Good point danlisa, these look like they are stuffed with mashed potatoes or sth. If these were not opaque, they would probably be simply black and that does not look good either. Or one might see some optics within them... I don't know
