S-400, NATO codename SA-21 'Growler' is newest Russian SAM system. Although it look identically as previous towed S-300 pmu-2 (SA-10) SAM system, it has newest surface-to-air missiles inside, with a range, enlarged to 240km. Also, it has different tractor BAZ-6402, replaced oldest KrAZ-260. Meantime S-300 still stay in service as main Russian SAM system, and newest BAZ-6402 tractor also can be used to tow oldest S-300 pmu-2 launchers. This may confuse, because it make older SA-10 looking like newest SA-21.
