The primary method of detection of submerged submarines is sonar. We also see magnetic anomaly detectors used at close range.
submarines are important because people need to go under the sea and do what they got to do to save the world
The sea floor, under water mountains, sea life, under water lava flows, etc.
20,000 Leagues Under the Sea; Captain Nemo's Nautilus.
U boats- for Unterseabooten (under sea boats)
The word "submarine" simply means "under the sea". (Sub meaning below, marine meaning sea)
Sonar
Submarines probably can't be seen, but we might find them with sonar, or possibly with a magnetic anomaly detector of some kind.
Yes, airplanes fought in the air, and battleships, cruisers and submarines fought at sea and under it.
submarines dont sail idiot
The Bering Sea is fairly shallow, but yes, submarines transit the Bering Sea regularly heading to and from the Arctic.
Submarines do get sunk in the sea.
Yes definitely. Maybe not military class submarines but there are many public submarine tours that take you under the water to see shipwrecks, sea life etc
