This is only a few days after the massive drone attack in Russia. Only a matter of time until we have drones smart enough to dodge bullets (or at least dodge out of where guns are pointing) while flying at breakneck speeds being controlled by AIs we don't fully understand. The tech industry is working hard to bring about the Terminator future.
And Great Britain just announced plans to deliver 100,000 of them to Ukraine. Ukraine lacks the manpower compared to Russia. It seems logical to strengthen their forces by deploying these flying mini terminators. I believe we are not far from large-scale drone warfare. In World War II, we had epic tank and aircraft battles; now, the time has come for autonomous drone battlefields.
I think we're already deep into large-scale drone warfare. Destroying a third of the enemy heavy bomber fleet is pretty substantial. It feels to me like that attack operated like Pearl Harbor, a marker that the old way of surface naval warfare / air attack was being replaced by a new one.
Don't forget that Russia has their own drones. They were the first to deploy the fiber-optic cable drones as an anti-ECM measure. And of course both sides are ordering parts from China.
