Panserkanon m/65

The Panserkanon m/65 is a Ringeriker Self Propelled Howitzer introduced into service in 1965, it has seen multiple upgrades and rebuilds over it's service life and has spawned a series of derivatives. It originally mounted the same L/26 147mm armament as used on it's towed counterpart making use of cased separate loading ammunition capable of firing out to 17.4km with standard HE shells. It was introduced into service alongside a more lightweight 105mm armed counterpart which was to fill the direct support role however this system was short-lived with almost all examples being rebuilt into other models by 1983.

Panserkanon m/65F1
The m/65F1 came into service in 1978 featuring the new L/38 147mm armament of the Kanon 77, and introducing a bagged charge system, ammunition stowage was increased from 28 to 36 complete rounds and the firing range to 21km.

Panserkanon m/65F2
The F2 model was introduced in 1993 and features a 45-caliber armament, capable of firing out to 28km and further increased ammunition to 40 rounds and 64 charges as well as a new digital fire control and communications systems, automatic gun laying system and an inertial navigation system, allowing the platform to be much faster in and out of action.

Panserkanon m/65F3
The Panserkanon m/65F3 entered service in 2017 and features the same 147mm L/51 armament as the other in-service platforms such as the Katapult Artillery System and Haizum howitzer as well as integration into the new digital battlefield control and awareness network, allowing Observer-Effector digital fire control, the F3 is only loosely a variant of the original with a number of components reused however migrated to a new chassis based on that of the Villkatt (AFV).

m/82 Ammunition Supply Vehicle
The m/80 is an ammunition carrier, mostly built from the rapidly retired 105mm armed variant, it carries 95 complete 147mm rounds and is usually employed with one carrier per section (two m/65s) allowing the section a greater deal of autonomy from the battery echelon and improving survivability. It has been replaced by a variant of the TATC.

m/76 Command Post Vehicle
The m/76 command post vehicle is externally identical to the ammunition supply vehicle however it is fitted with communications and planning equipping in order to fulfill the requirements of battery and regimental command post functions. It was updated in line with the m/65F2 to include digital fire control and communications, it has since been replaced by a variant of the TATC.
