These are four orders of magnitude above the Exocet.
They can be launched from land, aircraft, ship or submarine, and can coordinate from all platforms to arrive at target simultaneously, or in waves, from several different directions.
Worse, they can be coordinated with the Chinese land launched, ship killer ballistic missile which has a much larger range.
There’s a trade-off involved here, which is why Western navies and even ones like China still develop subsonic anti-ship missiles.
The Exocet is significantly smaller (can be launched from the torpedo tubes of an SSK or a 250T missile boat), can be retargeted and has better sea-skimming capabilities aka stealth. These Russian weapons don’t have those capabilities.
