making the Seawolf silent speed of 25 knots and doubling the Kilo endurance

How does the pump jet work sound-wise? I know what they are but I haven't a clue about the acoustics.

Yes you're right pump jet prevent cavitation. I'm still looking at which parameter to change so that the Seawolf would not be cavitating at high speed.

Right now it still cavitates at 25 knots at relatively shallow depths but it is nonetheless virtually undetectable
