Which device demonstrated the first military submarine use during the American Revolution?

• A. The Turtle invented the first submarine.
• B. Submarines were first used in World War I.
• C. The Turtle demonstrated the first military submarine use.
• D. The Turtle demonstrated sonar navigation.

Answer: (C)

The event tests the earliest use of a submarine in actual combat. The Turtle, built by David Bushnell and operated during the American Revolution, is credited with the first military submarine demonstration in 1776 when it attempted to attack a British ship in New York Harbor. It did not sink the vessel, but it proved that a vessel could travel underwater and deliver weapons without surfacing, marking the first recorded instance of submarine warfare. Submarines were not first used in World War I; that war saw extensive submarine action, but the concept existed well before. The Turtle is not described as the inventor of the first submarine in general, and sonar navigation did not exist at that time.
