New Tech: Submarine Cloaking Device?
 

Sounds very interesting. Hope the USN hasn't decommissioned the Memphis yet.:O:

Dead link for me.

I guess in theory there should not be any problem creating a submarine with a smoother speed of sound transition thus creating a more refractive instead of reflective surface.

But I'm sceptical if this will work for passive detection (though for diesel-electric subs in littoral environments this would be very sweet indeed :) )

Able to access it now. This is sweet stuff indeed.

Sure you might be able to detect a submarine passively. But don't the majority of ASW rely on active homing to find and destroy their targets in their terminal phase?
