Oerlikon Contraves 35 mm cannon are produced in several versions, the most important of which are the type KDA for anti-aircraft and ground use, the type KDB which is produced primarily for use on the twin anti-aircraft gun type GDF series mountings, the type KDC-01 which is used primarily as a naval twin mounting, the type KDC-02, a part of the NDF-C modification package and also integrated in the Oerlikon Contraves 35 mm Twin Automatic Anti-aircraft Gun GDF-003 and GDF-005, and the Type KDE which is a version produced primarily for use with gun turrets for light armoured vehicles. All these various types differ in details and weights. The type of ammunition feed varies according to the type but can be linked, belted or from a hopper.

On the 35 mm KDE, ammunition feed is selectable from either the left or right side and the time required to change from one type of ammunition to another is less than 1 second. Oerlikon Contraves has produced various ammunition feed systems for use with the KDE cannon, in the form of either magazines or automatic ammunition feeders incorporated into the turret.

In the Oerlikon Contraves system the K stands for Kanone (Cannon), D stands for 35 mm calibre and the A, B, C, E, and F stand for Type.
