| | Diesel-electric - Wikipedia, the free encyclopedia |
 | | When the diesel engine was first installed in submarines before the First World War, it revolutionized submarine tactics because its range (or operating time) far surpassed that of the gasoline engine, and leaked vapors of its fuel were far less prone to explode within a submarine cabin. |
 | | Conventional diesel engines were unsuitable for this application, owing to the time that it took to reverse the engine and produce power, while a steam engine had the responsiveness to bring the barge safely into the slip (even though operated through an engine room telegraph to an operator). |
 | | By replacing the steam engine with a diesel electric unit (with parts commonality with a locomotive), maintenance was both simplified and reduced, several crew members could be eliminated, and the responsiveness to throttle operation (now directly controlled from the bridge) was substantially improved. |
