Intrepid Minute: Growler's Control Room

[0:09] Hi, I'm Bill Peters. This is another Intrepid Minute. Today we're on the submarine growler. A periscope is the only way to see outside a submarine. It doesn't work underwater, so it extends above the water from a depth of 65 ft or 20 m. On Growler, as with most submarines, we have two periscopes. I call them a pariscopes. The boat requires three people to drive. One steers and follows the direction on a compass. The bow planes controls the actual depth of the boat. Growler is depth tested to 715 ft or 218 m. And the stern planes control the angle at which the boat goes up and

[0:49] down. They sit here for 6 hours and are given their instructions by a diving officer behind them. These are the youngest people on the boat. Your first job is to drive. And while they sit here, all they have to do is look out the window. There are no windows. To learn more, visit intrepid museum.org. Stay tuned for another Intrepid Minute.
