Oerlikon GDF

Uncommon card · No. 88779

The Oerlikon GDF or Oerlikon 35 mm twin cannon is a towed anti-aircraft gun made by Oerlikon Contraves (renamed as Rheinmetall Air Defence AG following the merger with Rheinmetall in 2009). The system was originally designated 2 ZLA/353 ML but this was later changed to GDF-001. It was developed in the late 1950s and is used by around 30 countries. The system traces its origins to a post-war effort to develop a series of related autocannon classified by the calibre; 20 mm weapons became the KA series, 25 mm the KB, 30 mm KC, and 35 mm KD. As the first model in the 35 mm line, the gun itself is known as the Oerlikon KDA. Although single-gun systems have been used, the twin-gun mount became almost universal, and the KDA naming fell from use.
