Magnetic Silencing/Deperming Facility

USA / Hawaii / Iroquois Point /
 military, United States Navy
Outbound Submarines call these specialized deperming facilities, where heavy gauge copper cables are wrapped around the hull and superstructure of the vessel and very high electrical currents (as high as 4000 amps) are pulsed through the cables. This has the effect of "resetting" the ship's magnetic signature. It is also possible to assign a specific signature that is best suited to the particular area of the world the ship will operate in.
