The KORKUT is a Turkish all-weather-capable 35 mm self-propelled anti-aircraft gun (SPAAG) developed by Aselsan.
...each Korkut system comprises one command and control vehicle and three weapons platforms. Each weapon platform carries a twin 2×35 mm Oerlikon KDC-02 cannon, manufactured under licence by MKEK. Each weapons system can fire up to 1,100 rounds a minute up to a range of 4 km. The command and control vehicle has an effective radar range of 70 km.
ATOM 35mm airburst ammunition ejects tungsten pellets at a predetermined distance. It is a smart ammunition which has a base fuse. Together with the ability of precise time counting and the capability of being programmed during firing by taking muzzle velocity into consideration automatically sets the fuse to detonate the round as it approaches a pre-set distance from the target. Whilst a single pellet is too small to do major damage in itself, the accumulation of damage from multiple strikes is designed to destroy wings and control surfaces, sensors and aerodynamics, causing the target to crash. According to Aselsan, the ammunition is resistant against electromagnetic jamming.
