Status-6 Oceanic Multipurpose System

The Status-6, also known as Kanyon, is a purported nuclear-powered and nuclear-armed unmanned underwater vehicle developed or being developed by the Russian Federation. It would supposedly be able to deliver a thermonuclear cobalt bomb of up to 100 megatonnes against enemy's naval ports and coastal cities. "Kanyon" is the name given this drone by the Central Intelligence Agency.

This weapon is designed to create a tsunami wave up to 500 m tall that will radioactively contaminate a wide area on an enemy coasts with cobalt-60, and to be immune to anti-missile defense systems such as anti-ballistic missiles, laser weapons and railguns that might disable an ICBM or a SLBM. Two potential carrier submarines, the Project 09852 Oscar-class submarine Belgorod, and the Project 09851 Yasen-class submarine Khabarovsk, are new boats laid down in 2012 and 2014 respectively. Status 6 appears to be a deterrent weapon of last resort. It appears to be a torpedo-shaped robotic mini-submarine, that can travel at speeds of 185 km/h (100 kn). More recent information suggests a top speed of 100 km/h (54 kn), with a range of 10,000 km (6,200 mi) and a depth maximum of 1,000 m (3,300 ft). This underwater drone is cloaked by stealth technology to elude acoustic tracking devices.

Oscar-class submarines can carry four Status-6 torpedos at the same time for total yield of 400 megatonnes.
