Iran has announced the development of local-made S-300 missile under the name of Bavar-373 2404121.

"The production of an alternative missile system is underway,” he said, adding that the work “has yielded good results.”

Executive Deputy Head of Khatam al-Anbia Air Defense Base Gen. Shahrokh Shahram said a decision to produce domestically-developed Barvar-373 systems was made after Russia's refusal to sell S-300 systems to Iran.

Iranian military officials earlier said the missile system, called Bavar (Belief) 373, is even more powerful and more advanced than the Russian S-300.

On September 20, Commander of the Khatam al-Anbiya Air Defense Base Brigadier General Farzad Esmaili said that the Bavar-373 missile defense system uses two or three types of missiles to confront aerial targets in different layers.

The $800-million contract to supply Iran with the missile system was signed in late 2007. Russia was to deliver five S-300PMU-1 battalions to Tehran.

However, on September 22, 2010, Russian President Dmitry Medvedev signed a decree terminating the contract in line with UN Security Council Resolution 1929, which bans supply to Iran of conventional weapons including missiles and missile systems, tanks, attack helicopters, warplanes and ships.
