UKR sources report that in OCT, Russia carried out only five Kalibr 3M/54 launches in the entire month.
With 85% shoot down rate, only one missile actually struck the target.

Disguised to look like shipping containers.
Cost of export version is listed at $6.5 million. So, in October the cost to attack one target was $32.5 million.
A very expensive way to wage a war.
