Depends on how good the hydro-phone array is, and how good the wake tracking satellites image processing is ... At 6 knots you'll still throw a wake to the surface that is visible as a wave pattern unless you drive in circles, in which case you will not get there ... But, having allies with sneaky subs is a very good thing
