I was wondering the same thing. A few Russian mil bloggers were screaming about the size of the warheads in the recent drone attack on the A50 repair facility near Rostov-on-don. Generally the release the pics and talk about it. But deadly silence this time. As a result, I am assuming these are new drones. And if they are new, it is most probably the ones you are talking about. almost shahed is the rumor inside russia.
