From The Depths
Question about detection and tracking equipment
I tried finding a guide or something that does a good job of explaining the detection/tracking system in the game and what the pros and cons of the different types of detection/tracking. If there is one out there, I'd greatly appreciate it if I could be directed to it. If not, if someone could give a bit of a rundown of the pros and cons of each type.

My other main question is regarding how weapons use tracking. Like, do you have to have a piece of tracking equipment associated with each local weapon controller or, could you use something like the laser rangefinder tracker, that I'm assuming works 360 degrees in the horizontal and vertical diretions, track targets for all the weapon systems on a ship?

I can answer the second question, and the answer is no, all you need is that the detection is linked to the AI mainframe that is controlling the weapon(s)

AfaIk you only need the detection connected to one AI on the vehicle. You can have some AI for secondary weapons with no detection, and it'll use the detection from the other AIs.


Anyway, as for advantages and stuff (not complete, and all from memory):
  • Radar only works for above-water targets, and when above water itself. But works in any weather and with decent accuracy.
    Detected by passive radar.
  • Sonar only below water, and dito.
    Detected by passive sonar.
  • Visual works even at ridiculous ranges, doesn't suffer from stealth of a target, still works against underwater targets (because reasons; not sure if it works from underwater though).
    Detection range reduced in bad weather, and during the ~30 second nights. May or may not suffer from smoke.
    Can be "protected" using glass blocks.
    Detected by retroreflection sensors.
  • 5/7/9m range finders are visual sensors with better accuracy.
  • IR cameras are inaccurate, and have trouble detecting cold targets. However, they cannot be detected by passive sensors.
  • Passive radar/sonar can detect radar guided missiles/sonar guided torpedos, and radar-/sonar-using vehicles. Passive, so cannot be detected by any other detection system themselves.
  • Laser range finder trackers give great accuracy, but do not work through smoke. Can be "protected" using glass.

You generally want several detection systems. Usually 90° sensors too, if possible (better range and accuracy). Keep the required processing power, and the detections per second in mind as well.

Thank you both very much for the answers. I now have two additional questions:

1) What's the use of IR cameras if they are inaccurate? I understand they can't be detected, but that doesn't seem like much of a benefit. which leads into my second question...

2) What's the use of passive radar/sonar and retroreflectors? Unless things have changed since last summer with combat, you'll always know when you are going into combat and are able to see other ships. you even know what ships are being brought into the fight. So being able to detect an enemies sonar/radar/cameras doesn't seem to be very useful.
1. Might be that they need low processing power (can't remember). Also an option if you build a really small vehicle that manages to be semi-stealthy, but don't want to rely on passive detectors.

2. Passive radar and sonar are usefull for anti-missile, and especially anti-torp defences.
Also, they obviously detect where the enemy is, but only when they use the corresponding active sensors. May have worded that in a poor way before.
And iIrc retroreflection is actually reasonably accurate.

But still, how do you be stealthy in a game where there's a big notification of a battle starting and having a preperation phase?
The enemy will get no, or very few readings of your position, and may end up with errors of several hundred metres. That can significantly reduce the ammount of fire you take.

Visual sensors still tend to work however, and missiles and torps will probably still home in on you if you're unlucky.
Ah ok that makes a lot of sense now. I was thinking of stealth in the sense of like an FPS.
Infra Red and "stealth" could be a bigger thing if Nick adds the impact on day and night to the detection system, so optical cameras cant see in the dark for example

If I'm not mistaken, they have reduced range in the night. But the nights are about 30 seconds long, so that wouldn't do much anyway.

Theres a few on youtube such as : From The Depths: Gentleman's Detection Guide
This was made early when they were put into the game, hope it adds onto what was already said

Thanks. I'll check it out.
