The Bavar-373 is Iran’s version of Russia’s S-300 surface-to-air defense system. It is said that the Bavar-373 encompasses technology that is “more advanced” than the S-300. Iran’s system is intended to intercept cruise missiles, ballistic missiles, as well as other airborne targets.1
Iran began developing the Bavar-373 system around 2010, after it was determined Russia would not sell it the S-300PMU-2.
In September of 2012, Iran reported that development of the Bavar 373 was 30% complete. Iran aims to have the system ready for deployment by 2013.2
Since the system is currently in development, not much is known about its overall capabilities. More information will be added as it becomes available.
