Immersive techniques for the true subsimmer!

[bstanko6]

I had to look at the date when I made this thread! It feels like yesterday I wrote it. Now with all the great additions people have given to it... “Immersive techniques for the true Subsimmer” is alive and well. Thanks to all who takes time out of their day to read my nerdy rhetoric!

You are very welcome!


Using some of your techniques, such as "Periscope Discipline" I managed to complete the entire SH5 game!!

I should be the one thanking you here!

And Tbh, some of your "nerdy" things are kinda cool imo.
Your setup is pretty cool, I saw the video on your YT channel.
Your immersive techniques are cool as well.

And this is coming from a middleschooler who doesn't really like the nerds in his grade. At least, they don't do the stuff you do!

Keep it up man!

LOL! Glad it helps Beast!

DAILY TRIM DIVE AND ETO REGULATING:

Trimming -
Dive to PD (all dives initiated at GF, ~16 kn) and drop to 1.5 kn (KF), Chief trims the boat at KF. If rough weather, instead trim at anywhere from 20-60 m. The boat was hard to hold at PD over sea states corresponding to winds over 10 m/s. So go deeper to trim at winds 11-15 m/s.

Regulating Etos -
Then to 30-60 m for an hour or two to regulate the Etos. All depth changes at 4.5 kn (HF). Cruise at 3 kn (LF).

When surfacing after running submerged awhile, first to 20 m for sound check at KF, then to PD for scope check. Up scope at just above 20 m on the way up, then SHIFT+F just before it breaks the surface so your chief holds a depth to keep the scope head low in the water. Scan, then down scope, GF (~ 7 kn) to decks awash, scan with UZO. If all clear, surface. Stay on bridge til Chief tells you you are running both diesels and can charge batteries (by then you would also know all tanks have blown). Go below, order charge batteries.

TORPEDO LOADOUT:
(Ato is G7a, Eto is G7e)

VIIA -
All bow tubes loaded with Etos. Bow reserve 2 Atos and 4 Etos. Stern tube an Ato. (Total 8 Etos, 3 Atos)

VIIB and VIIC -
All bow tubes loaded with Etos. Bow reserve 2 Atos and 4 Etos. Stern tube loaded with an Eto. Stern reserve an Ato. Both externals Atos. (Total 9 Etos, 5 Atos)

Why -
Etos required maintenance every few days on various components. Thus they needed to be accessible. The external eels therefore had to be Atos. The two Atos in the bow room were those under the floor plates. These were not immediately accessible due to the two eels sitting atop the floor plates, which were covered by wood boards (yep, bow room was a crowded place). The stern reserve was an Ato too as space for maintenance was insufficient.

Atos also needed maintenance (primarily charging the air tanks), but it was not critical to do so on a schedule as was the case with Etos.

The VIIA aft tube was not accessible and thus needed to be an Ato.

ATTACK CONDITIONS:

Seek to attack -
1. Out of the sun.
2. Facing the moon (from the dark side).
3. From the windward side, that is, upwind of the target.
4. For a stern shot (day) with moderate winds, say, less than 9 m/s, from the downwind side. In heavier winds, say 9 to 11 m/s, still attack from the windward side, even for a stern shot.

No submerged attacks over 11 m/s winds. These correspond to sea states at which it was nearly impossible to hold periscope depth in real life.

No submerged attacks at winds of 0 or 1 m/s. The sea is like glass, and any ripple of the scope can be seen. The only exception is on bright moonlit nights, at dusk, or with a very bright sun.

The winds corresponding to the ideal sea states for a submerged attack are 4 to 5 m/s.

For night surface attacks, anything below 15 m/s should be fine. And remember, approach on the “Hundekurve”, bow stays on target!

No recognition manual except for well-documented ships (warships, maybe Liberty ships)! IRL books did not have the extensive data that we have in the game. Use Ausdampfen (matching course/speed), plotting etc as recommended in the U.Kdt.Hdb. Only resort to data gathering through the scope in a pinch, or as confirmation of data obtained on the surface, and then only eyeballed!
