Islamic Republic of Iran Air Defense Force

Turkish Air Force personnel are attending a training for S-400 missile defense systems in Russia.

Iran has unveiled its new domestically developed and manufactured air defense system. Earlier, Iranian officials called the Bavar-373 the first such system in the country.

Tehran started making Bavar, which means "I believe" after the purchase of the Russian C-300 system was halted in 2010 due to international sanctions.

Turkish military personnel in charge of operating S-400 missile defense systems are set to arrive in Russia at the end of May, a Russian military source has said.

Iran has tested its home-grown air defence system, designed to match the Russian S-300, the head of the Revolutionary Guards' air defense has said.

"In parallel with the deployment of the S-300, work on Bavar-373 system is underway," Farzad Esmaili told state broadcaster IRIB late Sept. 2.

Iran has received its first delivery of S-300 air defense systems from Russia, Iranian Foreign Ministry spokesman Hussein Jaber Ansari said on April 11.

Russia has delivered to Iran the first batch of its S-300 air defense missile systems, Iranian Foreign Ministry spokesman Hossein Jaber Ansari has said.

"The first batch of the Russian S-300 air defense missile systems has arrived in Iran," Iran's TASNIM news agency quoted him as saying on Monday, TASS is reporting.
