When a towed array is used this blind spot is covered by it. For hull-mounted sonar it is cone-shaped area behind the sub, approx. Sonar will not detect contacts in baffles. 200ft above bottom (if someone has more precise number please let me know).īaffles is blind spot/area from which a sonar can't hear sounds. Some may have towed sonar tails, essentially a cable with hydrophone sensors dragged behind the sub (or ship). Player will typically "go active" only in an emergency situation such as close range fights.Ī sub will always have hull-mounted sonar arrays on bow and sides. As you're radiating very loud sounds, it gives away your presence and bearing to the enemy. As sound will bounce off objects like submarines and ships, measuring time to return and direction will provide very precise bearing AND range information in several pings. It will emit a sound wave ("ping") and listen for returns or echoes of that sound. In game this uncertainty is reflected in SOL Solution reliability percentage.Īctive sonar - function is similar to radar. Range can be estimated by level of the sound (louder is probably closer), but precise range and course of target needs to be observed and calculated by Target motion analysis (TMA). Passive sonar will provide only direction to target. Passive sonar - array of sensors listening to sounds in water, complemented by computer(s) to visualize and evaluate them. Q: Sonars - difference between active and passive sonar towed vs. Again not sure if this happens in game or not.

Similarly sub with towed sonar sitting just above the layer would be able to listen for signals under layer.

Udaloy) have towed sonar arrays ("tail") that may be lowered under the layer not sure if this is modelled in game.

Note the layer does not block 100% of sound so you still may be detected even across the layer.

The enemy will probably detect the torp much later, reducing his reaction window, giving him less time for counter fire and evasive maneuvers.

A good tactic is to fire a torpedo from the opposite side of layer and have it change depth only after activation.

Layer can be used to "hide" from an enemy for a stealthy approach.

If you can't detect anything when under layer, try coming above it, the target is probably there and you might be in his shadow zone.

A Sub below the layer will be more difficult to detect by ships and subs above the layer and vice versa.

Video explaining layer, surface duct, shadow and convergence zones: Įffects of layer on sonar detection and tactics I'm not sure if CZ are modelled in the game yet, anyway combat in CW takes place at much shorter distances so CZ's would not influence us anyway. CZs form concentric circles around the source and targets can be heard over the horizon from 2nd or even 3rd CZ in good conditions. CZ may let a ship hear other sources of sound that are too far for direct contact.

Sound waves reaching very deep waters will eventually return back to the surface in area called Convergence zone (CZ) as far as 30 miles away from source.

This creates " shadow zone" just under the layer, where a sub can be hidden from surface ships (but at the same time it can't hear the surface ships).

The sound that penetrates the layer will then curve according to depth and temperature.

The sound is effectively "funneled" between surface and layer - this is the Surface duct.

A part of sound travelling from the surface downwards will be deflected by the layer and then curve back to the surface and then back to the layer etc.

Current "strength" and depth of layer is displayed in game in CONDITIONS tab.

Strong layer will deflect more sound energy, weak layer less.

High seas or currents will weaken the layer. The layer will not form if water is not deep enough.layer or thermocline is a boundary between warmer surface water and colder deep water which acts as a kind of sound barrier, deflecting part of sound energy coming to it from above or below.:) I tried to produce an answer that is simple without being too simplistic sorry if I offended someone's scientific sensibilities :) If you have any more questions, I'll be happy to answer!Ī: I believe this innocent question is worth several thick scientific books.

I'm not a great sub expert but I hope these will help new submariners to understand the game faster. I realized I once prepared similar guide for a friend so I updated and polished it and would like to publish it here for all new sub simmers. When watching live streams of the great submariner and youtuber Jive Turkey ( ), I noticed several questions appear regularly.
