Default Just an idea, conclusions required ;)

Attention on Deck
Hiya Sailors,

I have been playing SHIV for a while now and I recently had this idea in mind.

Supposedly I receive a report that a Merchant is headed my way straight, we'd both collide head-on if I dont immediately crash dive.

What about If I am to dive to 49 meters, ready and open all tubes, and raise periscope underwater, remain stationary and adjust lightly so that we are both on the opposing bearings( head-on)?


Look









Now, I have few questions in mind;

In the first image,

What time torpedo takes to go from point A to point B on the first image, if the torp is a G7e (T3)/ G7es (Falke)?
(Depth = 49 meters, shallowest depth achieved by settings = 1.1 meters)

Dont do mathematic, cuz I could have done it myself.

I want the real thing..

Is it possible to get a magnetic pistol to work at point B?

would the torp blast give an effect similar to under keel detonation (magnetic) ??


In the second image

at what distance in meters would I be able to see the vessels keel when submerged??

Sorry for the exam type questions.

Anyways, skippers, board your vessels and try this out, let me know how it turns out.

Torp loadout is optional, but for consistent feedback (control), please use specified torpedoes (G7e/G7es Falke)

Thanks..

You cant fire a torpedo from 49m, not sure if you can either open tubes at that depth. You need to be at periscope depth.

In a type XVIII I could.. Tried it by pressing Q as we ent deeper, the one time I had

"too deep to launch torpedos, sir" was when I reached 50 meters.

so, 49 meters in XVIII boat is the launch depth...

The maximum depth at which torpedoes could be launched from Uboats is 15, and some maybe 20 meters, 49-50 meters is no way possible. I'm guessing that at that depth it would either make the torpedo implode due to pressure, or just mess up the trajectory and everything. You can however open the tubes at pretty much any depth I think. It's the torpedo that counts not the submarine, since both a type VII and a XVIII could launch a G7a G7e etc.

I hardly believe that the torpedo would implode at 50 meters... The probable reason was the added pressure required to lunch it.

Default Seeing the hull

1. Someone will correct me if I'm wrong but I'm fairly certain that by the time you see a ship's hull in your periscope from underwater you are WAY too close to even use your torpedoes. Even if they did work, you are almost guaranteed to waste at least two torpedoes out of a shot of four unless you converge them which, again, makes no sense and is a waste of your ordnance.

2. Why would you want to set up an attack like this anyway? In the same time it would take you to do this you could manoeuvre left or right and have a beautiful 90-degree shot from your aft tubes. You would just have to sit and wait for the ship to cross your path. In other words why set yourself up to hit a small target (a skinny bow) when you can set up for a large target (a nice fat side of hull)?

3. If you are so close that you have to "crash-dive" then;
a. Your watch crew is doing an extremely lousy job at spotting
targets, and
b. The merchant will NOT be continuing straight towards you
anyway but will be zig-zagging rendering a nose-on shot both
impractical and that much harder.

4. In other words it would appear to be an extremely poor tactical choice for an attack.

USS PirgoS (my home town old name ), Thanks.

Your video is interesting too.
btw try some mega mods, they really improve gameplay, stock game is buggy as alexradu89 mentioned.
Not sure if you can use that kind of attack with them.

Gentlemen. At my understanding no Type XVIII U-boat were completed in reality. All were cancelled before completion. Could you tell me where you got max torpedo launch depth for this U-boat type?
