Routine dive

1. Routine dive only ordered by Captain
2. Captain orders "Prepare to dive", descends into conning tower, closes voice tube on the bridge.
3. Helmsman uses telegraph and switches from diesel to electric motors, then orders ahead half.
4. Navigator takes a depth sounding, reports depth under keel.
5. Navigator marks on chart where boat’s location is at the start of the dive.
6. Captain closes conning tower hatch, says “Conning tower hatch is closed"
7. Dive Officer sets dive planes, tells Captain “Ready to dive”
8. Captain orders “Flood”
9. Helmsman opens the forward MBT #4 vent valves allowing seawater in the main ballast tanks.
10. Navigator opens the aft MBT #2 vent valves allowing seawater in the main ballast tanks.
11. Captain sets depth with order “Go to depth, xx meters”
12. The boat is dived at a down angle of 5-8°. In so doing, the ordered depth is initially overshot by about 2-5 meters, and the ordered depth is approached from below by the Dive Officer's operation of the dive planes.
13. After the report of Dive Officer: "Boat is at xx meters", the order always follows, Captain: "Close vents".
14. Helmsman and Navigator closes MBT vent valves.
15. Navigator reports any leaks or problems, “No leaks detected, Herr Kaleun”.
16. Captain orders new speed, course as necessary. If at periscope depth, the slowest speed should be selected.
17. Helsman reports battery status, “Both batteries at xxxx amps, Herr Kaleun”.
18. Sonar reports any contacts.

Crash dive

1. Order: "Alarm!" Alarm bell activated by Chief.
2. Helmsman switches from diesel to electric motors, then orders ahead flank.
3. Captain closes voice tube on the bridge, descends into conning tower.
4. Navigator takes a depth sounding, reports depth under keel.
5. Navigator marks on chart where boat’s location is at the start of the dive.
6. Captain closes conning tower hatch, says “Conning tower hatch is closed"
7. Helmsman silences alarm bell.
8. Dive Officer sets dive planes to forward hard down.
9. Captain orders “Flood”
10. Helmsman opens the forward MBT #4 vent valves allowing seawater in the main ballast tanks.
11. Navigator opens the aft MBT #2 vent valves allowing seawater in the main ballast tanks.
12. Captain opens the Negative vent valve allowing seawater in the negative tank.
13. Captain sets depth with order “Go to depth, xx meters.” (At the front usually to 80 meters)
14. Once the down angle indicator indicates the boat has a down angle, hold: 8 to 15°
15. Helmsman closes vent valve for negative tank and blows tank to control dive before desired depth is reached. After execution of the order "Flood" and the boat has a noticeable descending tendency, the negative buoyancy tanks are expressed (blown by compressed air), by the Helmsman, who will call out, “Express”. It is critical that the Helmsman perform the crash dive operation competently, otherwise the boat could dive out of control, below safe depth, or with a dangerous down angle.
16. The ordered depth is achieved by the Dive Officer’s operation of the dive planes.
17. After the report of Dive Officer's: "Boat is at xx meters", the order always follows, Captain: "Close vents".
18. Helmsman and Navigator closes MBT vents valves.
19. Navigator reports any leaks or problems, “No leaks detected, Herr Kaleun”.
20. Navigator checks compressed air level and reports, “Compressed air at xx millibar, Herr Kaleun”.
21. Captain orders new speed, course as necessary.
22. Helmsman reports battery status, “Both batteries at xxxx amps, Herr Kaleun”.
Sonar reports any contacts.

Surfacing

1. Captain will order a sonar sweep for nearby vessels.
2. Sonar reports any contacts held and strength.
3. After the Captain has satisfied himself by visual sweep and sound bearings that the boat can surface, he gives the order: "Prepare to surface"
4. Helmsman reports “Vents closed”
5. Captain: “Surface”
6. Helmsman will open the high pressure air valve to blow the main ballast tanks, with the report, “Blowing main ballast tanks”. To surface, the boat goes to Ahead Full because, if immediate diving is required (aircraft alarm), high speed is absolutely necessary. The boat is angled stern down and driven up dynamically with diving planes "Forward hard up", "Aft up 5-10".
7. Dive Officer to Captain: "Boat rises".
8. Dive Officer to Captain: "13 meters, 12 meters…." meter by meter.
9. Dive Officer to Captain: "Conning tower hatch free", order concluded at 7.5 meters.
10. Helmsman closes compressed high pressure air valve and Dive Officer sets planes to neutral.
11. Captain will set the bridge watch (usually Captain and Navigator).
12. Captain ascends the bridge ladder, opens hatch and says "Conning tower hatch open".
13. Navigator marks position of surfacing on chart.
14. Captain opens bridge voice tube.
15. As necessary, Captain may order, “Switch to diesels” and set new course and speed.
16. Sonar reports any radio traffic or messages received.

Estimating your torpedoes' time to impact

The TDC has a built in Time to Impact feature, but here's how you can doing it manually. When you have your firing solution and shoot your torpedoes, start your stopwatch by pressing T

Then grab your handy calculator, enter the range that you used in your firing solution and divide by 15.4 .This will give you the estimated time to impact in seconds.

Example: you estimated the range to the target as 1400 meters, then divide 1400/15.4 = 94 secs

To change the estimate to minutes and seconds, simply subtract 60 seconds from the total until you are left with a remainder that is less than 60.

Example: Estimated range is 2600m divided by 15.4 is 168 seconds. 168 - 60 = 1 minutes and 68 secs, so subtract another 60 and you have 2 minutes and 48 seconds. That's about as fancy as the math gets on this calculation so even Bernard can handle it

------------

Remember: the time to impact estimate will depend on how accurate you were with your range estimate.

Press R to reset the stopwatch, and to hide it.

FYI: The torpedoes in your Wolfpack U-boat run at 30 knots, which is 15.4 meters per second.

Here is a tutorial I've made for setting up a "Fast 90 Attack" in Wolfpack.





Further discussion for this Tactic

Enjoy,

Default Wolfpack Tactics & Tips

Hi All,

I’ve made tables for the method I use in my Comprehensive tutorial in my sig (computing target speed based on his bearing change over one minute). I’ve put a link to it in my sig. I used a self made whiz wheel in my tutorial but wanted to make the tables for ease of use So people could print them off and keep them at their desk. Instructions are in the document.

Tutorial is written using SH3 but of course the methods work for Wolfpack as well.
