China’s “Underwater Great Wall” effort to create anti-submarine systems is growing more sophisticated.

This solution could not only help submarines sense where they are without risking exposure, but also elevate a tactical ...

China's latest innovation can track the quietest vessels and submarines using the magnetic fields generated by their wakes.

The technology is far from operational. While similar sensors have proven reliable in detecting low-flying aircraft over shallow waters, the challenge could be far greater in the open sea.

The Navy plans to equip the larger SWATH ships with active sensors— LFA—to enhance deep water submarine detection and location capability and to provide shallow water detection. The small ...

Attack submarines are designed to seek and destroy ... acquisition and life-cycle costs while providing enhanced passive detection capabilities. The new bow also replaces the 12 individual ...
