Nothing like nucs! 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. :-) :-) :-) --- þ SLMR 2.1a þ This note from El Cajon California USA * Origin: Try Our Web Based QWK: DOCSPLACE.ORG (1:123/140) .
