S-125 Neva/Pechora
The S-125 Neva/Pechora (Russian: С-125 "Нева"/"Печора", NATO reporting name SA-3 Goa) is a Soviet surface-to-air missile system that was designed by Aleksei Isaev to complement the S-25 and S-75. It has a shorter effective range and lower engagement altitude than either of its predecessors and also flies slower, but due to its two-stage design it is more effective against more maneuverable targets.
