US making drone submarines to patrol oceans

Yahoo

Have you heard of unmanned drone submarines that can patrol the oceans? The US Department of Defense is creating such submarines that will navigate the oceans, tracking and following enemy subs for months at a time, Russian news agency RIA Novosti reported.

The Defense Advanced Research Projects Agency (DARPA), which is responsible for developing new military technologies, started the project because "the growing number of adversaries able to build and operate quiet diesel electric submarines is a national security threat that affects US and friendly naval operations around the world", according to a statement on the DARPA website.

SAIC , Science Applications International Corporation , has already been awarded the $58 million contract to create a prototype of the vessel . The submarine will be able to patrol the US coastline for up to 80 days at a time. The main task of the vessel will be to patrol the waters for enemy submarines and then chase them away if located. The sub will also gather information deemed necessary by the US government .
