Caterpillar Drive

Overview
"Run Silent, Run Deep" is the motto of the catterpillar drive. For the game it is not an engine but a special to make your sub rather stealthy.

"A magnetohydrodynamic drive or MHD propulsor is a method for propelling vessels using only electric and magnetic fields with no moving parts (hence its silence), using magnetohydrodynamics. 

''The working principle involves electrification of the propellant (gas or water) which can then be directed by a magnetic field, pushing the vehicle in the opposite direction. Although some working prototypes exist, MHD drives remain impractical."'' (Photo/Video)

Information
Decreases the range at which opposing ships can detect your submarine. For foes with Sonar specials it drastically reduces the range of their Sonar detection.

 * THE HUNT FOR RED OCTOBER discussed a mythical cat drive.
 *  She was built with a revolutionary  stealth propulsion system called a "caterpillar drive", which is described as a  pump-jet system in the book. In the film however, it is shown as being a  magnetohydrodynamic drive.
