Northrop delivers light-weight wide aperture array submarine shipset

Northrop Grumman Corporation has delivered the first shipset of LWWAA hardware for Block IV of the Virginia Class Submarine to the U.S. Navy

Northrop Grumman has delivered the first shipset of LWWAA hardware for Block IV of the Virginia Class Submarine to the U.S. Navy.

This represents the 19th shipset that Northrop Grumman has supplied for the VCS program.

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.”

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.

Northrop Grumman has been delivering LWWAA panels for all VCSs, starting with the USS Virginia, SSN-774. The start of the first Block IV shipments represents the beginning of a series of 10 shipments that will be delivered at a rate of two per year to Huntington Ingalls Industries. Northrop Grumman will provide the acoustic array assemblies as well as all the hardware required to install the arrays on the exterior of the ships.
