CMANO - Making Tactical Decision Aids


If my ship cavitates at flank speed and there is no enemy sub with a Lua trigger recording the event, will I learn anything?



Ok, I admit it, this is a click bait. Now that I got your attention, this image is the result of an early attempt at recursively generating ships and subs.

Tactical aids come in all types and forms. There are the ones that simply show a tactical situation and help the commander to make a decision. There are others that help the decision making by providing likely outcomes given a particular tactical situation.

CMANO is a very versatile simulation platform. Its scenario editor allows the player to create an scenario with outstanding easiness. What would happen if this ship is here and an enemy sub is here searching? Would the ship get detected?

Addressing such a situation with a CMANO scenario is easy because the initial positions for both the ship and the sub are known beforehand. Alas, the commander rarely knows the position of an enemy submarine. In this blog entry I want to share the results of a tactical aid I generated for a virtual US ship commander that is in a hurry to sail south. He wants to know what are the likely submarine initial positions from which he can be detected.



The setup. A US Ticonderoga-class guided missile cruiser (blue icon) is navigating sout at flank speed. Unknown to his commander, a DPRK submarine (a SSN of the Severodvinsk-class, yeah I know I am not Tom Clancy) can be anywhere 50 nm from him and will start patrolling the circular area highlighted with the yellow reference points.

In the screenshot above, the start of the scenario is shown, with the US warship in the center and an enemy submarine, 50 miles away, which can be seen because I'm using God's eye view.

The scenario runs automatically and recursively with the help of a few Lua scripts.The sequence of events is as follows:

1.   The scenario starts

  1.   A counter is initialized. This counter keeps track of a series recursive ship vs sub simulation runs
  2.   Units are added to the scenario
    1.   The US warship is placed in the center and give a course due south, at flank speed
    2.   A DPRK sub is placed 50 miles from the US ship and given a patrol area delineated by the reference points above
  3.   If the US warship remains undetected and reaches an escape area south of the DPRK patrol's area
    1.   All units are deleted
    2.   The counter mentioned in 1.1 is advanced
    3.   New units are generated
      1.   A US warship is placed in the center and give a course due south, at flank speed
      2.   A DPRK sub is placed 50 miles from the US ship and given a patrol area delineated by the reference points above. The DPRK sub initial position is not the same as the one used in the previous simulation run. This initial position is advanced clockwise from the initial position of the US warship
  4.   If the US warship is detected
    1.   A marker reference point is made at the initial position of the DPRK sub. The marker is labelled "Danger" because this an initial sub position that will generate a headache for the US commander.
    2.   All units are deleted
    3.   The counter mentioned in 1.1 is advanced
    4.   New units are generated
      1.   Same as 3.1
      2.   Same as 3.2



A typical scenario start. The ship and sub placed, just waiting for me to start the thing by clicking the Start/Resume button.

Looks like a Steel Beasts image and caption wandered into the thread. :laughing4
