as for ASW helicopters or patrol planes ... a submarine can hear low flying aircraft depending on the depth of the sub. American subs have hindsight sonar on a scope to listen to the baffles.
This whole thing should be awake up call for Sweden to get serious about ASW.
Don't the Swedish have subs that can take a quick search around?

True, when a helicopter get lower the rotor makes "pressure" on the water which can be heard(If I remember it correctly)
The Swedish Navy know this and therefor they got only so and so low before they lowered the sonarbouy.
It is a wake-up call for the Swedish politician.
Have read some chat questions and answer from some expert.
few of these question was "Is Russia preparing to invade Sweden?"
The expert: No
My thought about all this
If it is a Russian sub, it is there for two reasons
1. Replace old equipment
2. Testing the Swedish navy's ASW-possibility
I guess it is number 1, ´cause this sub got into trouble and now it try to escape into international waters, where this Ns Concord await.
