Tehran, November 30 (KCNA) -- Iran is taking steps one after another to increase its defense capability.

The minister of Defense and Armed Forces Logistics of Iran said on Nov. 29 that a large number of home-made anti-aircraft guns were delivered to the Islamic Revolution Guards Corps of Iran.

This artillery is reportedly able to detect and intercept flying objects with the help of radar and optical system and destroy targets at sea as well.

Earlier on Nov. 27 three Ghadir-class submarines, each of 120 tons, were deployed in Iran's Navy.
