Conning Tower & Periscope - Pearl Harbor, Oahu, HI - Outdoor Interactive Science Displays on Waymarking.com

The conning tower consists of a cylinder, eight feet in diameter, located above the control room section of the submarine's pressure hull. It contains equipment for steering the submarine and firing torpedoes. There are two submarine periscopes inside the conning tower. The one located closer to the submarine is the "Observation and Navigation Periscope". It provides a wider angle and better optics than the attack periscope located next to it."

At USS Bowfin Submarine Museum & Park, visitors are welcomed to go inside the tower and use a periscope for a view of Ford Island, USS Arizona Memorial and Battleship Missouri Memorial.

Submarines use complex periscopes using prisms and/or advanced fiber optics instead of mirrors, and providing magnification. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction.

Periscopes allow a submarine, when submerged at a relatively shallow depth, to search visually for nearby targets and threats on the surface of the water and in the air. When not in use, a submarine's periscope retracts into the hull. A submarine commander in tactical conditions must exercise discretion when using his periscope, since it creates a visible wake (and may also become detectable by radar, giving away the sub's position.

Scientific Principle(s) being demonstrated: Periscope utilisation inside of a conning tower (see detailed description) Briefly explain if the experiment was effective for you. Could it have been better?: It was effective even if the barrel is very narrow and therefore cannot receive many people at the same time. We enjoyed using the periscope and the view. When is the apparatus/experiment available to the public: Daily from 7:00 AM To 5:00 PM Closed on Thanksgiving, Christmas, and New Year's Day
