The innovations, many details of which are secret and not available, include quieting technologies for the engine room to make the submarine harder to detect, a new large vertical array and additional coating materials for the hull, Navy officials explained.
“We are talking about changes in sensors and changes in the capabilities aboard the ship that we think could be very dramatic in terms of improving our ability to compete in our acoustic spectrum,” Rear Adm. Charles Richard, Director of Undersea Warfare, told Scout Warrior in a special interview.
The idea with “acoustic superiority,” is therefore to engineer a circumstance wherein U.S. submarines can operate undetected in or near enemy waters or coastline, conduct reconnaissance or attack missions and sense any movement or enemy activities at farther ranges than adversaries can
Acoustic sensor technology works by using underwater submarine sensors to detect sound “pings” in order to determine the contours, speed and range of an enemy ship, submarine or approaching weapon. Much like radar analyzes the return electromagnetic signal bounced off an object, acoustics works by using “sound” in a similar fashion. Most of the undersea acoustic technology is “passive,” meaning it is engineered to receive pings and “listen” without sending out a signal which might reveal their undersea presence or location to an enemy, Richard explained.
Testing of these innovations is now underway on board an experimental prototype version of a Virginia-Class attack submarine called the USS South Dakota.
Described as a technology insertion, the improvements will eventually be integrated on board both Virginia-Class submarines and the now-in -development next-generation nuclear-armed boats called the Ohio Replacement Program.
“The testing going on with the acoustic superiority program is more on the sensor side of the house. We see ourselves on the cusp of a fourth generation of undersea communications,” Richard added.
