While it was created from the same project, hence the common S-300 designation, different priorities resulted in a design quite different from the other versions. The S-300V system is carried on tracked MT-T transporters, which gives it better cross-country mobility than even the S-300Ps on 8 × 8 wheeled transporters. It is also somewhat more distributed than the S-300P's.
