Washington: 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.

Normally, anti-submarine warfare has been conducted by US Navy captains at the helm of ships, but humans will never board these drones, also known as a "Continuous Trail Autonomous Vessels", according to Discovery News.

The subs will be able to patrol the US coastline for up to 80 days at a time covering thousands of kilometres using non-conventional sensor technologies that "achieve robust continuous track of the quietest submarine targets over their entire operating envelope", DARPA stated on its website.
