Acquisition and target-designation radar of the S-300PMU and S-400
The large 3D search radar of the S-300PMU/S-400 battalion: a phased array mounted on a heavy semi-trailer that rotates 360° (or covers a 180° sector). It provides the air picture and target designation to the command post, including for ballistic targets in a 60° sector. Recognisable by the large rectangular antenna face on a semi-trailer behind an 8x8 tractor.
