TDC vs Periscope

[maillemaker]

But after reading the TDC walkthroughs I am hitting 80% of the time. Is the periscope worth using since I am getting such good results?

You have to use something to target with and feed bearing data to the TDC - either you use the periscope or UZO optics.

You might want to try the Fixed Wire method of attack. It makes range calculations unnecessary.

1) Sail your sub so that your heading 000 is just in front of the target ship track. Set your scope bearing to 000.

2) As the bow of the target ship crosses your vertical reticule, start the stopwatch. As the stern of the ship crosses your vertical reticule, stop the stopwatch.

3) Identify the ship in the recognition manual to determine target ship length.

4) Calculate target speed using this formula:

(ship length in meters * 1.94) / time in seconds

5) Turn sub to intercept target ship track at 90 degrees.

6) Go to TDC. Turn on TDC manual input. Set AoB to either 90 degrees port or starboard. Dial in target speed. Turn off manual input.

7) Go to scope and turn it until gyro angle reads 000.

8) Go back to TDC, turn on manual entry, and tweak AoB back to 90. Turn off manual entry.

9) Go back to scope and tweak to 000 gyro angle. Open tube doors for firing.

10) When target ship crosses crosshairs, fire torpedoes as the parts of the ship you want to hit cross the vertical reticule.
