Submarine Propulsion Systems. During World War II, most American submarines were powered by diesel-electric systems. This was a departure from earlier submarine power systems, which were direct drive types, little changed from the earliest boats. In this direct-drive power system, the diesel engine is directly connected to the propeller shaft.
The U.S. Navy's submarines are nothing like that-they're practically spotless, huge submarines. For example, the Ohio class (Trident) submarines are almost 2 football fields long, 7 stories tall from keel to sail, and wide as a 3 lane highway. It's hard to realize how big they are because most of it is submerged.ow that we're underway and you've got the hang of how the submarine maneuvers and tracks contacts, we'll settle into the daily routine. First up-The Watch Cycle. Submarines operate on a 6 hour watch cycle. The crew is divided into 3 watch sections, and each section stands watch for 6 hours, then gets 12 hours off.
