A nice open source analysis from HiSutton regarding the Russian Navy's strategic nuclear torpedo (more a nuclear UAV really) known as Status-6 Kanyon.

Russian Status-6 Intercontinental, nuclear armed, undersea autonomous torpedo Demystified
Since the US DoD released a Nuclear Posture review citing the ‘Status-6 AUV’ as having been tested, commentators are forced to accept that the Status-6 (NATO: KANYON) intercontinental, nuclear-armed, nuclear-powered, undersea autonomous torpedo is a military fact. Some observers had been watching the developments for some time however. This brief analysis details a selection of my original research into the subject.
Open Source Analysis
A. The OSINT trail starts with the special test submarine B-90 Sarov. Originally laid as an improved KILO Class submarine, she was heavily modified over a protracted construction cycle to serve as a special test submarine. She was commissioned in 2008. A key feature is a very large hangar-like weapons bay in the bow which is much larger than would be needed if she was only intended to test regular sized torpedoes. In the past the Russians had grafted additional test torpedo tubes onto the bows of old diesel-electric submarines – Sarov is a completely different beast and only makes sense in the context of KANYON.
B. Initially B-90 Sarov was involved in testing regular torpedoes. The below photo, from 17th Oct. 2009 shows her being loaded with test torpedo in external tube, presumably in hangar. The weapon appears to be 533mm or 650mm. Geolocated to 64°34'41.69"N, 64°34'41.69"N in Severodvinsk on the White Sea where Sarov is based.
C. In 2009 she was modified with a longer bow with new hangar doors. This suggests that the size of KANYON had increased during development:
D. In 2010 a KANYON test round (likely size and displacement only) and related lifting/loading frame began to be visible in commercial satellite imagery of Severodvinsk. This is the earliest example:
E. Since then the test KANYON round and related equipment has appeared in numerous satellite images and some photos (two better known examples posted here, cross-referenced with early satellite images). The test KANYON round is only 18-19 meters long, compared to the stated length of 24 meters revealed by Russian media in 2015.
F. On 20th Dec 2012 the OSCAR-II submarine K-139 ‘Belgorod’ is re-designated as the Pr.09852 in laying down ceremony at Sevmash (here).
F. In 2013 Russian media reported on a new system under development called Skif (Скиф). The name caused some confusion because KANYON was virtually unknown in the public sphere and it sounded similar to the “SKIFF” missile (SS-N-23) carried by Russian Navy DELTA-IV class ballistic missile submarines.
G. On 27th June 2014 the Pr.09851 Khabarovsk submarine laid down at Sevmash shipyard in Severodvinsk (TASS). This we now know is designed to carry 6 KANYON rounds.
H. On 26th Dec 2014 Russian media article stating that B-90 Sarov is helping to test a new generation of “robotic means for submarines” (Источник: субмарина "Саров" помогает испытывать роботов для подлодок нового поколения)
I. 9th Nov 2015, the now infamous leaking of the Status-6 strategic nuclear torpedo on Russian TV station (YouTube). And the rest, as they say, is history...
The Status-6 was met with some incredulity in Western media, possibly because it was hard to imagine the concept of operations. The weapon does make some sense when viewed as a second-strike weapon, intended to literally go under missile defenses.
