A few potentially interesting dots to add to the Nyonoksa accident. We know that the Rosatom people who died worked at the KB-12 design bureau at VNIIEF. It's an interesting entity. Was set up in 2013, apparently by combining some KB-1 and KB-2 divisions 1/n 
The word is that KB-12 was set up for a specific (and fairly big) project. Which seems to be the case - KB-12 was given the status that is (almost?) equal to that of other VNIIEF design bureaus - KB-1 (physical packages) and KB-2 (weapons) 2/n
It appears that the person who was put in charge of that project ("general designer of one of the themes and chief designer of the institute [VNIIEF] for coordination of the work on this theme") is Aleksandr Ivonin, who came from the Rosatom HQ 3/n
It's interesting that Ivonin is not a nuclear physicist - his expertise appears to be in optics and in guidance and fusing systems (he has a number of patents on weapons and fusing). Note that the appointment was made by Kiriyenko 4/n
Even more interesting is that he is also the acting director of MOKB-MARS design bureau (mokb-mars.ru/?page_id=2). It's a space design bureau, but in 2017 it was transferred to Rosatom. Among other things it works on "guidance systems for cruise missiles developed by Raduga" 5/n
Raduga, of course, is the design bureau that developed the Kh-55 and Kh-101 cruise missiles, which Burevestnik, as shown on that video , closely resembles 6/n
These dots appear to point in the direction of the Burevestnik theory. However, it's still not quite clear what was the scenario of the accident. I think there are still unresolved questions about the current working theory, the recovery operation (not to mention a live test) 7/7
