MTU Submarine engines

The more specific and complex the demands, the more important and valuable expertise and experience are. For decades, we have been setting quality and performance standards for submarine technology.

Submarines are an indispensable component of nearly every fleet, taking on a number of tasks – from protecting territorial waters to gathering information on an international scale. Few manufacturers are in the position to fulfill the extremely high technical demands that are placed on submarine systems and engines. As a trusted partner of shipyards, ship designers and Navies, we have been optimising battery charging units for conventional submarines for decades. In fact, most conventional submarines around the world use MTU engines.

Our newly developed charging unit - based on the MTU Series 12V 4000 - addresses advanced submarine system requirements by improving and enhancing the characteristics of our world leading legacy submarine engine. The standard battery charging unit can easiliy be customised with project specific generators and mounting system for indivdual shock, acoustic and other Naval requirements – including magnetic signature reduction.

Cutting-edge technology

Charging units optimised for low acoustic, magnetic and thermal signatures.

Unparalled engineering

Further improved power to weight ratio and specific fuel consumption.

The next fully qualified evolution.

In 2009, MTU’s partnership-based corporate strategy resulted in the development of the current generation of submarine engines – based on the successful series 4000 engine family.

The MTU series 4000 engines have proven to be extremely reliable in various commercial and naval applications for almost 25years. 

Over 50,000 of these engines have been supplied to date, including over 6,000 in marine application alone. The total service life of all of these engines together comes to an incredible 190 million operating hours!

This vast field experience in combination with MTU‘s product improvement processes ensure continuous technology improvements over the entire product life cycle.
