Sonar is used on both ships and submarines to track the sea bed and measure depth. Many large fishing vessels are sonar as well to detect large groups of fish. Though it isnt as detailed as radar during the Cold War, it provided a sense of warmth in the cold matters (The New Illustrated Science and invention Encyclopedia, 61). Sonar wasnt developed until after many liners had lost their passengers and a need for a detection device. Though it was originally developed to detect icebergs, it had a greater use during this time to detect oncoming submarines. Had sonar been developed earlier many ships who may have lost innocent lives to war submarines may have survived to carry more passengers across the Atlantic instead of being swallowed up by its ferocious currents.It was just like a scene from the movie Titanic as the steamship majestically floated out of the New York harbor May 1, 1915 carrying one thousand nine-hundred and twenty-four people.
