According to US media reports on April 22nd, Iran demonstrated the latest version of the "Bavar-373" long-range air defense system during a military parade on April 17th. Iranian sources claim that the upgraded "Bavar-373" has stronger target detection and tracking capabilities, capable of identifying up to 100 aerial targets simultaneously. The upgraded "Bavar-373" is a significant progress in Iran's defense industry, reflecting its growing self-sufficiency and ambition to build a more advanced air defense network, according to reports. This system can intercept fifth generation fighter jets, such as the F-35 stealth fighter produced by Lockheed Martin. Foreign media quoted Iranian officials as saying that the upgraded "Bavar-373" air defense system has reached or even exceeded the capabilities of the Russian S-400 air defense system. The domestically produced "Bavar-373" in Iran was first put into use in the Iranian armed forces in 2019. At that time, some media reported that the "Bavar-373" had a similar appearance to the Russian S-300 air defense system, and its performance was comparable to that of the American "Patriot" air defense system.
