I wish people would stop treating the various versions of the S-300 as a single system. The S-300P and S-300V were developed by different Soviet enterprises (Almaz vs Antei), different missile design bureaus (Fakel vs Novator), have different radars, and different capabilities. https://t.co/XafgvhkZgl
