Actually that's not the case. Just 2/3 years ago, there was a time when over 80% to 90% Russian attacks were taken out by AD. It got to a point where they had to use cheap transistor decoys used in Radios worth like 2 dollars per transistor, in KH-101. So it would emit multiple frequencies confusing AD radar due to fusion of frequencies.
The Ukranians showed it to the Americans when one KH-101 was shot down with top area intact with these electronics. The Russians used Kinzhal's and Onyx missiles also to test their package parameters and eventually created a mix of weapons for strike.
Since then, there is always a package, nearly 100-300 objects in each wave. Wave 1: drones, it keeps the AD processing unit busy tracking these objects from inside the Russian territory. Then subsonic and supersonic missiles. AD gets overwhelmed and 25% object hit their targets. If you read my previous posts, that's the same % I'm using for Brahmos success.
The main question for us is, Russia is a weapons manufacturing nation, we can't compete with them. Do we have the capacity to get into a long term war and generate 100 to 300 objects once or twice a day? So based on our answers, we need to get to work and prepare urgently.
