Where Quiet Comes From

Lake Pend O'Reille provides the perfect spot for acoustic research.

Tucked away in a quiet little mountain town in Idaho that is best known as a great place to vacation by Lake Pend O'Reille, the Naval Sea Systems Command's Naval Surface Warfare Center Acoustic Research Detachment, or ARD, in Bayview, Idaho provides a wide range of research and development programs for the Navy in the area of ship and submarine hull and propulsion design. The research detachment's work has resulted in improved sonar and acoustic stealth performance as well as advanced propulsion systems for several types of submarines.

The facility has also focused on advanced surface propulsion systems and acoustic and electromagnetic signatures aboard surface ships. The ARD was first established after World War II to support ship testing, and in the 1960s it began to focus on submarine acoustic research. The ARD plans to continue developing sonar domes and propulsion noise reduction for the Navy's submarines and surface ships. Watch the video above to find out more about the ARD's mission.

    They test scale models at ARD, not full-scale submarines. One of the models, LSV 2 Cutthroat, is the world's largest unmanned underwater vehicle. You can check out its specs here: and tidequals700 and ctequals4 I'm pretty sure that a video of Cutthroat operating is part of National Geographic's "Super Sub" episode of their Explorer series: I'd include a link to the video, but alas, NMCI has blocked Youtube access during business hours to conserve bandwidth use.

    What's so hard to believe about this? The USS Henry Clay (SSBN 625) used Holy Loch, Scotland in 1968, for pre-patrol sea trials following a crew change. Can't have been the only boomer to use a lake for training and evaluation.

    I don't think the bring sub's to Idaho. The test the systems that are used on the subs.

    When someone told me the size of a sub I thought he was joking. Not surprised at the location. Sub bases are not at widely known locations.

    I grew up in those parts and never had a clue.

    Very interesting story. I would have never guessed the Navy tested subs in a lake in Idaho.
