Actualy the last designs gave off an almost imperceptable wake. SO
difficult to see form the air that the US Navy developes a Super
Sensitive "Sniffer" that could smell the Diesel Exhaust. The ASW plane
then sirculed arroound the area until lthe Tail Stinger picked up the
deflection of the earths magnetic field by the mass of steel i nthe
Submarines hull.
BUT it was purely a matter of "OUT HOUSE LUCK" to actualy find a sub
lurking off the coast.
Even now days with al lthe Puffed upo Pride of the Carrier Groups a
Nuclear can sneek under them and Pop a Red Flare up on the Flight deck
basiclt any time they want to do so. AND they know where the sub is
most of the time BEFORE the training exercise starts. :-)  :-)  :-)
