|New Contact! An intelligence gathering mission by a us Sturgeon class SSN, 130 nm off the coast of the Kola peninsula.|
The mission is to track Soviet SSNs returning to the Severomorsk naval base. In the book I linked above, you will find the details of such type of missions. These included recording the passive sonar signatures, which I'm sure is likely doable with some .lua scripting.
|Rules of engagement. We are not at war so we are not going to fire at those Soviet submarines.|
|Closing in at flank speed. At 30 knots, the sound of my own submarine masks a lot of the passive sonar contacts. The Soviet contact is lost (6 minutes 45 seconds refers to the time of the last contact, the last known position is also plotted).|
|The highest speed at which contact is not broke is 22 knots. The estimated position is still lousy and we don't have an ID on the tracked target yet.|
|With a lot of care, I was able to maneuver my sub (blue icon) very close to the SovietSSN (red icon). It turned out to be a Victor type. Note the scale at the bottom right of the screen. That's pretty close. The closest I could get was 200 meters.|
