Why is there no image of the sinking ship? Because at sea in war zone? Wouldn't Ukrainian army want to show image from their drone after hit? New satellite image coming soon?
Apparently it sank during a storm so probably getting visual confirmation to share was though. The drone was used to distract the radar, probably got shot down.
(Publicly accessible) satellite images weren't immediately available because of cloudy conditions, from what I read on news reports about the incident.
