Iran’s Defense Ministry today launched a warship cannon production line to produce 40-mm naval canons with the optimal range of 12 km (more than seven miles). The Fath 40 canon is designed as an anti-cruise missile weapon.
"The Fath 40-millimetre naval cannon has the optimal range of 12 kilometers and shoots 300 projectiles per minute and can be used against cruise missiles," Iran's Defense Minister Mohammad Mostafa Najjar said. “This weapon is an anti-aircraft low-altitude weapon and is used on warships.” [Fars News Agency, 24 May 2009].
