For tactical use, no. The frequencies are too high to be used for anything tactical. They are often used as part of machines for cleaning mechanical parts aboard ship though. Submarines use sonar (sound navigation and ranging), in much the same way that airplanes use radar (radio detection and ranging).
Submarines use the ultra sound in sonar in order to find any hurdles in their path as visibility is very less under water.
Submarines typically use air tanks. Oxygen is very dangerous and very flammable. It's use is very limited on submarines for that reason.
Animals use ultrasound but i do not know what animals do,
Doctors use ultrasound to check the health of an unborn baby.
yes when you get an ULTRASOUND when your pregnant it use ultrasound waves to show the image.
submarines and bats both use sonar. Calvin was here
oceanographers use submarines to take pictures of sea life and things that have been found or things that they are looking for.
The marines do not use submarines. Only the Navy does.
Most submarines have propellers that spin, pushing them forward. A few smaller research submarines use a water jet for propulsion.
Ultrasound is below the threshold of human hearing. Howler monkeys use ultrasound because it travels much further than higher frequencies.
