 My name is Alan Griffiths. I'm the director of the Acoustic Research Attachment here in Ponderay, Idaho. The testing and evaluation that we do here has a direct impact on the performance of our fleet submarines. So it's very important that we have unique assets, such as the LSV-2 that you see beside me here, that we can cheaply and effectively test technology before it goes to the fleet. The Acoustic Research Attachment performs acoustic stealth research and development primarily on submarine stealth technology before that technology goes into the submarine fleet. So we use a unique fleet of large scale models and ranges here located in Lake Ponderay to perform that mission. It's chosen to be here in Bayview, Idaho primarily because of the Navy Training Center that was established here during World War II. And little did they know at that time what a unique treasure that Lake Ponderay would become to support acoustic stealth technology for the Navy. This facility has become the Navy's premier acoustic research laboratory. Over the years, the Navy has invested heavily in establishing a fleet of large models that we test out here in Lake Ponderay. And we've established permanent lake test facilities to support these models. We utilize our models here to test pretty much any aspect of a submarine. The hull shape, the materials, the control surfaces, the propulsor, even the structure inside of how a submarine is made. We'll test systems that are installed inside of a submarine as well. So pretty much any aspect of a submarine that has an impact on its acoustic signature, we have the ability to test and evaluate here. So we can take measurements here that just can't be taken anywhere else in the Navy. It's deep, 1150 feet deep. Roughly the main channel where we test is about four miles wide. The lake itself is 46 miles long. Very large lake, absolutely the perfect acoustic environment for us. The acoustic research attachment has played a role in evaluating basically all the relatively new type of submarine shapes have been evaluated and tested here and we're positioned to support the future class of submarines as well. Our main mission of our facility is really quite simple, help provide the Navy the quietest submarine platform they can afford to provide so our sailors can go do their job safely and effectively and return home safe to their families.
