Submarine Torpedo Tube
A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the sea at the ambient pressure of the water around the submarine. Thus a submarine torpedo tube operates on the principle of an airlock.

Famous quotes containing the word tube:
“The last best hope of earth, two trillion dollars in debt, is spinning out of control, and all we can do is stare at a flickering cathode-ray tube as Ollie “answers” questions on TV while the press, resolutely irrelevant as ever, asks politicians if they have committed adultery. From V-J Day 1945 to this has been, my fellow countrymen, a perfect nightmare.”
—Gore Vidal (b. 1925)
