Reply to comment by deliveryboyy in At least six Russian missiles hit Ukrainian city of Kharkiv -regional governor by Quantum_II

The s300 used in "ground" mode, uses an INS and contrast identification during it's terminal phase. It's still guided, albeit badly. The S300 is also much faster than the jet engine on a cruise missile.

S300 in ground mode is launched on a ballistic trajectory, hence me referring to them as ballistic missiles. It being slightly guided on that ballistic trajectory doesn't make it not a ballistic missile.

Ballistic just means indirect fire.

Your original statement also included "dumb", which is also incorrect.

Also, the INS makes the missile, per definition, guided.

Furthermore, almost all AA systems were originally developed to also counter ballistic threats. It's been a core requirement since the inception of AA.

I agree, the "dumb" definition was incorrect on my part.

I might be less knowledgeable on the matter than you are, therefore I'd like to ask. Why does Ukraine currently has much more issues with shooting down ground mode s300 than with cruise missiles like Kh series?

Cruise missiles are terrain hugging which allows them to be shot down by manpads while the s300 requires a more robust aa system to engage. Ukraine is saturated in manpads so cruise missiles have a hard time.
