I was a submarine sonar tech in the United Stated Navy. You are so wrong.
So what makes you think the sensor is a sonar device?
So why do you think the Swedish sub isn’t as detectable as any other sub of similar size and shape using an active sonar system?
Ever rip off a big nasty with an ALFS system?
In your opinion, how effective would a Virginia SSN, assigned to a Carrier Battle Group, be in detecting, tracking and targeting the Swede? Seems to me, our SSN’s would be our best defense.
