Conflict relevance

This is the catalogue's single record for this system. It is relevant to the module below; each module's Force Atlas shows how it is used there.

Battlefield role

Long-range strategic air defence — documented throughout the war defending Crimea, the border regions and Moscow; the outer layer of the network that has kept Ukrainian aviation back from the front, with a documented secondary ground-attack role.

Strengths

Very long-range radars and interceptors deny high-altitude approaches across a wide arc; dense integration with Pantsir point defence; the reach to threaten aircraft far behind Ukrainian lines.

Limitations

A high-value target with documented battery losses in Crimea to ATACMS and Neptune strikes; struggles against low-flying drones and naval drones beneath its radar coverage; its marketed reputation and documented performance have diverged publicly over the war.

Campaign relevance

Derived: a participant organisation in these campaigns carries a typed equipment association with this system. That is not the same as documented use of the system in the campaign itself.

Visual identification

8×8 transporter-erector-launchers with four large missile tubes raised vertically when deployed; accompanied by large flat-faced phased-array radar vehicles; deployed as dispersed battery sites, not single vehicles.

Documented conflict use

Engaged throughout the war from Crimea, the border regions and around Moscow; multiple documented battery and radar losses in the 2023–24 Crimea strike campaign; documented use of its missiles in a surface-to-surface role against land targets.
