South Korea installs new submarine monitoring system at busy ports.

South Korea has built a new port surveillance system with indigenous technologies that improve detection of quiet submarines and other underwater moving objects, the arms procurement agency said Wednesday.

The advanced maritime surveillance system, developed by the Agency for Defense Development with a 130 billion- won ($106.6 million) budget since 2015, has been installed at major ports across the country, the Defense Acquisition Program Administration (DAPA) said.

The new system adopted an advanced underwater acoustic sensor designed to detect those objects early and share their location information with the military on a real-time basis, as it is linked to the Navy's major command control and surveillance systems, it added.

"This will contribute to strengthening the defense industry's competitiveness by improving the military's surveillance of underwater moving objects and securing the possibility of exporting them abroad in the future," DAPA said in a statement.
