Panserkanon 44

The Panserkanon 44 was a family of armored fighting vehicles, primarily Self Propelled Gun carriers developed to provide a mobile fire support platform and Tank Destroyer to the recently expanded armored forces of the Ringerike Army, the Pk.44A was originally intended to function more as an assault gun than self propelled artillery, but this decision was reversed not long after it's entry into service, which lead to the development of the Pk.44C, which remained as the primary self propelled artillery of the Ringerike Army until it's replacement with the Panserkanon 127 starting in 1967.

Panserkanon 44A
The Panserkanon 44A was armed with a 105mm Howitzer based on the and intended to function as a self propelled howitzer/assault gun, being placed within infantry assault gun companies with six assault guns in each brigade and within dedicated artillery regiments. It was soon decided that this function was made redundant by other in service platforms, it was however realized that a much more effective self propelled howitzer could be made based on the same vehicle with minimal effort, thus leading to the Pk.44B.

Panserkanon 44B
The Panserkanon 44B was originally intended to be fielded with a 57mm Anti-Tank Gun, however with advances in foreign armor development the decision was made to re-arm the platform with a more powerful 75mm Gun, which was capable of defeating most potential adversaries, the Pk.44B was withdrawn from service in the 1950s.

Panserkanon 44C
The Panserkanon 44C saw the development of the Pk.44A platform into a more effective self propelled howitzer, armed with a newly developed lightweight howitzer firing Semi-fixed 105 x 372mm ammunition out to an effective range of 10km, this variant was then further updated throughout it's life cycle as the Pk.44C until its full withdrawal in 1976.
