How different are modern submarines?

Visitors who have served on our latest submarines tell us that they are completely different from the USS Pampanito (SS-383) and exactly the same. They are telling us that the functions are the same – diving, surfacing, being quiet, being sneaky, gathering intelligence, and attacking the ships of an enemy in wartime. However, the way those functions are accomplished may be very different. Buttons, switches and computers help to accomplish many tasks that were very manual on the Pampanito. In addition, modern submarines are much larger and cleaner. However, there still isn’t enough space to play basketball.
