S-300 is very potent system.
It is its range of 200-300 kilometers and possibility of simultaneous attack on several targets what makes him very dangerous.
Also low-flying is not of any good, it can track and attack targets at 20 meters altitude.
So far, they have learned this:
An analysis of the plans has demonstrated a weakness. But the approach will not be easy. You are required to maneuver straight down this trench and skim the surface to this point. The target area is only two meters wide. It's a small thermal exhaust port, right below the main port. The shaft leads directly to the reactor system. A precise hit will start a chain reaction which should destroy the station. Only a precise hit will set off a chain reaction.
Then we shall fly at 19 meters! (with a nod to The 300). That's 60 feet, the Israelies could do it.
