Someone on this board must know the history of MB diesels.
Did M-B build diesel engines for German submarines before WWI? Did M-B build diesels for the German Navy during and before either 'WW' war. What boats/ships were powered by M-B designed or built motors?
What other military vehicles used by the German Army did M-B build diesels/powertrains for? The pre-cursor of the Gelandewagen (Unimog)? What else?

Why do I ask? Two reasons. First, I've wondered where Chester Nimitz studied when he visited Germany to study diesels. The U.S. Navy eventually built the first diesel powered ship and submarine seen in the U.S. based on Nimitz recommendations and real world knowledge learned in Germany. Second, I want to read some confirmation of an opinion that the motor noise one hears at 75-80mph bring is not unlike what one would hear if one were crew on 'Das Boat'. Is it just me or are OM617 motors the grandchildren of marine diesels?
