LWWAA is the only available fiber-optic passive hull mounted sensor array in the market and is critical to the operation of the U.S. Navy’s VCS fleet. The technology is central to the development of future generations of undersea sensors. There are six arrays in each shipset.

"LWWAA gives the Navy a distinctive edge over sensors being used by any other naval force," said Alan Lytle, vice president, undersea systems, Northrop Grumman Mission Systems. “The early delivery of this first Block IV LWWAA shipset continues a tradition of 114 consecutive early array deliveries by Northrop Grumman Undersea Systems in support of the Virginia Class Submarine program.”
