Ships with GE Marine Gears

The Nimitz-class carriers (CVN68 through 76) are the largest warships in the world. Their missions demand immediate and sustained power levels and uncompromising reliability over an estimated service life of 50 years. Each of the carrier's four propellers is driven by a GE multiple-input, double-reduction, locked-train (MDT) reduction gear powered by one high and one low pressure GE steam turbine.

The DDG-51 Arleigh Burke-class guided missile destroyers are considered by the Navy to be its most capable and survivable surface combatant. The propulsion system utilizes GE's high power density (HPD) gearing with half the weight and required space compared to conventional designs. The unique gear design and mounting system bettered the stringent noise requirements resulting in the quietest surface combatants in the fleet. Each of the ship's two propellers is driven by a GE multiple-input, double-reduction, locked-train (MDT) reduction gear powered by two GE gas turbines.

The SSN-688 Los Angeles-class attack submarines are one of the most advanced undersea vessels in the world. Their design achieved a step improvement in speed and noise reduction, with the aid of GE propulsion gearing, over their predecessor the Sturgeon- class. The ship's propeller is driven by a GE multiple-input, double-reduction, locked-train (MDT) reduction gear powered by two GE steam turbines. The gearing service life for this class is 40 years.

The Trident/Ohio-class fleet ballistic missile submarines (SSBN) are the most survivable element of the U.S. nuclear deterrent system. They are expected to be the primary nuclear deterrent system for the 21st century. The ship's propeller is driven by a GE multiple-input, double-reduction, locked-train (MDT) reduction gear powered by two GE steam turbines. The gearing service life for this class is 40 years.

Military Sealift Command's newest class of ships-Large, Medium-speed, Roll-on/Roll-off Ships (T-AKR)-can carry an entire U.S. Army Task Force, including 58 tanks, 48 other track vehicles and more than 900 trucks and other wheeled vehicles. Each of the ship's two propellers is driven by a GE double-reduction, locked-train (DT) reduction gear powered by a GE gas turbine.

The LHD5, 6 & 7 are part of the largest amphibious assault ship class in the world. They are uniquely designed to be able to sail in harm's way and provide a rapid build-up of combat power ashore in the face of opposition. Each of the ship's two propellers, on the LHD5, 6 & 7, is driven by a GE multiple-input, double-reduction, (MD) reduction gear powered by GE low and high-pressure steam turbines.

GE reduction gears are used to reliably transmit power in LNG carriers transporting liquefied natural gas - a very dangerous cargo. GE low and high-pressure steam turbines, through a GE multiple-input, double-reduction (MD) reduction gear or a multiple-input, double-reduction, locked-train (MDT) reduction gear, power the ship's propeller.

GE reduction gears are used in numerous cargo, container, carrier and tanker commercial ships. The San Diego Class tanker is one of nearly 300 tankers using GE reduction gears. GE low and high-pressure steam turbines, through a GE multiple-input, double-reduction (MD) reduction gear or a multiple-input, double-reduction, locked-train (MDT) reduction gear, power the ship's propeller.
