The KAFR ÚÉ 3M (Közel A Fegyverrendszerbe a Új Évezred, 3. Mintaz English: Close in Weapons System for the New Millenium, 3rd Pattern) is a close-in weapon system designed by Vertega Advanced Systems for mounting on ships. It is based on the SdAR TBA 35mm revolver gun CIWS, 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 3.3g 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 3M 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 3M gun and 252 rounds weighs 3,200kg. The gun's cupola is claimed to have a low radar cross section.
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 computer system uses an open architecture and is claimed to be compatible with many existing fire control systems.
The gun's ammunition capacity allows it to engage 10 anti-ship missiles or 20 surface targets.
