  • Testing A Turtle–July 21, 1776

    David Bushnell came up with the idea for the Turtle submersible only days after Lexington and Concord. He’d been working on several different experiments he’d conducted at Yale College, and found a way to integrate them into a single device to use against the British.

    The Turtle was revolutionary (heh) in a couple of ways: first, nobody had successfully created anything like it before, and more importantly, Bushnell (along with Isaac Doolittle) came up with the screw propeller as a means of maneuvering the vehicle. No water vehicle had ever used a propeller as a means of getting from one place to another, and while the design has been refined for various purposes and to improve efficiency, Bushnell’s propeller is easily recognizable today for what it is.

    It was pretty brilliant for its time, and in September we’ll see it in action, in New York Harbor.

  • September 7, 1775: Submarine Warfare is Revolutionary

    The Turtle, or the American Turtle as it’s often called, was invented by a man who thought it should be possible to stealthily attach a bomb to a ship and then detonate it shortly thereafter, by approaching the ship from under the waterline.

    The Turtle was a brilliant idea in concept, if not in execution. There were just too many things that had to go exactly right for the turtle to successfully execute its design purpose, and when it was first tried in genuine combat on this day in 1775, unfortunately it was not successful.

    But every failure is one step closer to success, right?
