Apparently the final tally was 12 planes, but still, an impressive display
The first casualty of war is the truth.
That being said, any sort of materiel loss on weaponry as important as strategic nuclear bombers is a massive problem for Russia. The logistics of repairing them, if possible, is going to be complex.
This was a massive damage, not directly interfering with war against Ukraine that much, but overall power projection. Plus a pretty good insult to russian's FSB and GRU services who had no clue, just like today's Crimea bridge blow.
I do not want to give any credit to russian secret service but as we have seen in 9/11 and 7th October - secret services in any country are sometimes clueless.
Oh well. Nothing that vodka and a window can't solve.
