submarines and bats both use sonar. Calvin was here
dolphins ,bats, and submarines all have echo location
Some common features of submarines is an adaptation to allow humans to survive and carry out our missions of research, pleasure or combat. I hope that I help you.. haha :)
There are different answers to that but the most common one is that the USN had 288 submarines in WW2
All use sound navigation / echo-ranging for navigation.
they use sonar like bats do to detect objects that are in their path

Many of the early submarines ran on diesel engines. These were used when on the surface for propulsion and power, as well as charging the batteries. When they submerged, they ran on electric power from the batteries.
