Short video of Oerlikon Milennium Gun in service with the Royal Danish Navy. This high-tech CIWS is manufactured by Oerlikon Defense and is one nasty little missile murderer. The Rheinmetall Oerlikon Millennium Gun or Rheinmetall GDM-008 is a Close-in weapon system designed by Rheinmetall Air Defence AG (formerly known as Oerlikon Contraves) for mounting on ships. It is based on the 35/1000 revolver gun land based air defense system, and uses AHEAD ammunition. A device at the muzzle end of the barrel measures the exact speed of each round as it is fired, and automatically sets the fuse to detonate the round as it approaches a pre-set distance from the target. Each round disperses 152 small tungsten projectiles weighing 3.3 grams (0.12 oz) each to form a lethal cone-shaped cloud to strike the incoming target. Whilst these are too small to do major damage in themselves, the accumulation of damage from multiple strikes is expected to destroy wings and control surfaces, sensors and aerodynamics, causing the target to crash. Other firing modes are designed to be effective against surface targets such as small fast attack boats. The Millennium Gun is housed in a low observable (stealthy) turret that is almost entirely self contained, it can even run on battery power alone, and it uses a modular control console interface that can be tied into many existing fire control systems. The gun’s ammunition capacity allows it to engage 10 anti-ship missiles or 20 surface targets.
