ANTISUBMARINE WARFARE The Navy's "...From the Sea''1 and "Forward...From the Sea"2 documents mark a sea change in Navy strategy by emphasizing battle space dominance and shifting focus from open-ocean, blue water operations to support of joint operations in the littorals. The littorals as an operating area, however, cannot be generalized, because virtually every variety of operating conditions can be found there, from deep (blue)

In particular, significant gains in passive sonar appear possible based on larger multidimensional arrays of lightweight, smaller, cheaper sensors and telemetry; multichannel processing exploiting the advancing massively parallel computing technology; and robust characterization or incorporation of the ocean environment. These gains can be applied directly to active acoustics as well.

A widespread and/or sophisticated mine threat can readily thwart, halt, or forestall many naval operations, and technology will continue to favor those who deploy mines over those who attempt to detect and destroy them. Nevertheless, the United States must provide the spectrum of MCM tools that allow our forces to move with battle group speed, maneuver in any theater of operations, and operate in support of national objectives.

· Using advances in sensors, signal processing, and computational power, autonomous or semiautonomous systems can be netted in an undersea surveillance system that uses distributed sensors and small undersea vehicles or bottom crawling devices to provide covert mine surveillance, deletion, and neutralization capabilities. These would be "smart" systems, with communications capability to operate autonomously in the most efficient manner, thereby avoiding personnel and platform losses.

· Focus passive and active ASW sonar development on exploitation of the ocean's intrinsic coherence and on use of large volumetric arrays, as enabled by massive computational power, miniaturized sensors, and high-bandwidth transmission links, with a goal of 20-dB or greater detectability gains beyond nearterm programmed improvements. · Develop networked, distributed sensor fields, including unmanned platforms (e.g., unmanned underwater vehicles (UUVs)

Develop the lightweight hunting and sweeping technologies required for these smaller units. · Apply reasonable mine shock hardening and effective acoustic and magnetic signature reduction technologies to all new-construction ships.
