The Nahkampfkanone 1 was an experimental Swiss tank destroyer that saw service between 1944 and 1947.

The Nahkampf cannon 1 was built onto the chassis of the armoured car Panzerwagen 39, Panzer 38(t) type LTL-H CSSR armoured fighting vehicle.

The chassis was extended by a roller produced by the company Berna in Olten.

The armour consisted of only thin sheet metal and, in initial experiments, only a 75-millimeter cannon was installed, before future designs sported a 10.5-cm howitzer.

The prototype was used by the Swiss Army with the car plate (M + number 7236).
