Hum, does this statement also apply to submarines equipped with
towed array sonars (which can be towed lower than the ship's depth)?
It would apply if the tow cannot get under about 2500 to 3000 meters. That presumes a slant range of 1700 meters to the sensor and a search path with some overlap. It'd need more passes at 2500' than at 3000' depths. The deeper it goes the less overlap is needed.
I'm idly wondering why a submarine would have a towed head that could go down that deep. I can't think of a military usage. (Of course, in this field my imagination is limited. {^_-})
