GDF-005

The GDF-005 is a twin 35mm anti-aircraft gun system, an upgraded variant of the Oerlikon GDF series. It is designed for short-range air defense against aircraft, helicopters, and cruise missiles, often integrated with a fire control radar.

Developed by Oerlikon Contraves in the early 1980s, the GDF-005 was created to introduce advanced digital control systems, automated ammunition handling, and a computer-controlled sight to the existing GDF series. It officially entered service in 1985, significantly reducing the required crew size through its automated power supply and diagnostic systems. While Swiss forces maintained them for domestic airspace defense, GDF series guns have been exported to over 30 nations and saw notable combat deployment during the Falklands War and the Gulf War. Today, the GDF-005 remains in active service globally, with many units being modernized to utilize advanced AHEAD ammunition to counter modern drone threats.
