caterpillar drive

Nor were they using the Red October's caterpillar drive system.

The caterpillar drive is particularly useful for quietly escaping the enemy.

The aft section of the submarine contains two ducts for the caterpillar drive.

A possible propulsion system for submarines is the magnetohydrodynamic drive, or "caterpillar drive", which has no moving parts.

The propulsion system is nicknamed "Caterpillar Drive", and makes sonar detection extremely difficult.

In the film version, the "Caterpillar Drive" is described as a magnetohydrodynamic system, essentially, "a jet engine for the water".

She was built with a revolutionary stealth propulsion system called a "caterpillar drive", which is described as a pump-jet system in the book.

The Universe's Caterpillar Drive.

In 1984, Soviet submarine captain Marko Ramius (Connery) commands Red October, a new vessel featuring a caterpillar drive rendering it undetectable to sonar.

Substantial use of Commercial off-the-shelf parts is part of the design of the vehicle, including a Caterpillar drive train (C18 diesel engine and an X300 series automatic transmission) and excavator.

The film adaptation of The Hunt for Red October popularized the magnetohydrodynamic drive as a "caterpillar drive" for submarines, an undetectable "silent drive" intended to achieve stealth in submarine warfare.
