From the H.I. Sutton Internet web site "Covert Shores" some details of the Russian nuclear-powered torpedo NATO code name Kanyon.
Thanks to the tip and original article as seen at the Russian media outlet RT.
Details of the latest and greatest Russian "Doomsday" weapon some specifications, parameters, capabilities, and discussion of possible American counter-measures.
"Russian 'Poseidon' Intercontinental Nuclear-Powered Nuclear-Armed Autonomous Torpedo'Poseidon' / 'Status-6' / 'Skif' seabed launched variant / NATO: KANYON"
"The Poseidon is the largest torpedo ever developed in any country. At around 2 meters (6.5 ft) in diameter and over 20 meters (65 ft) long, it is approximately twice the size of submarine launched ballistic missiles (SLBMs) and thirty times the size of a regular ‘heavyweight’ torpedo."
ATOMIC WARHEAD OF KANYON REPUTED TO BE MERELY TWO MEGATONS RATHER THAN ONE-HUNDRED MEGATONS AS ORIGINALLY THOUGHT. A BIG BANG NONETHELESS!
See this Russian language video courtesy You Tube. Kanyon carried to the target by a dedicated submarine and launched, autonomous from that point forward. Kanyon also can be deployed in the manner of a sea-mine?
Kanyon apparently hardly an on-the-drawing-board novelty but now accepted as a valid and dangerous weapon system! I also recommend the Internet web site "Covert Shores" highly without qualification or reservation. Outstanding.
