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. The Millennium gun is easy to install as it requires no through deck penetration and needs no supply of coolant, air or ship’s power to operate. However, it does need a power supply to recharge its batteries. Installation can take as little as sixty minutes and requires only six square metres of deck space. A Millennium gun and 252 rounds weighs 3,200 kg. The gun’s cupola is claimed to have a low radar cross section. The 35 mm Millennium Gun extends ship self-protection to ranges greater than any close-in weapon system.

Rheinmetall Oerlikon Millennium Gun is based on the 35/1000 revolver gun land based air defense system, and uses AHEAD ammunition. The weapon is designed to be controlled by an external fire-control system using either radar or electro-optical trackers. It is fitted with an optional onboard observation TV camera which relays imagery to an operator console from which it can also be aimed and fired in an emergency mode. 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 computer system uses an open architecture and is claimed to be compatible with many existing fire control systems.

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. Additionally it is also effective against submarine periscopes, offering an ASW capability.The gun’s ammunition capacity allows it to engage 10 anti-ship missiles or 20 surface targets.
