Possibly one of the scariest weapons ever devised, the Russian 2m39 Poseidon (aka Status-6) NATO: Kanyon, a 65-foot long nuclear-powered intercontinental torpedo with an estimated warhead as large as 100 mega-tons, may or may not ever become operational. Submarine wonk HI Sutton over at Covert Shores has been covering this device for the past couple of years.
To put the strategy behind such a weapon into perspective, Dr. Mark B. Schneider, a Senior Analyst with the National Institute for Public Policy, just penned an essay at Real Clear Defense that paints a grim picture.
“Poseidon is a strategic rather than a tactical nuclear weapon. Calling it a ‘torpedo’ is also a mischaracterization,” says Schneider, pointing out that it is a semi-autonomous nuclear-powered UUV drone.
The role of Poseidon appears to be to terrorize the U.S. and NATO into not responding to the initial Russian low-yield nuclear attack after the seizure of bordering NATO territory. Under its “escalate to de-escalate” or “escalate to win” nuclear doctrine, Russia is going to use nuclear weapons first. Deterrence and defense are necessary. A new generation of weapons is probably necessary to destroy the Poseidon. At a minimum, deterring genocidal nuclear attacks against our major port cities is a critical equity. There is no nice way of deterring genocide.
