Kanon 147mm m/51

The Kanon 147mm m/51 is a Ringeriker Towed, manually loaded 147mm Gun-Howitzer that entered service with the Ringeriker Army in 1951 as a Divisional Artillery piece before being being redistributed more widely following the introduction of the Panserkanon m/65, it saw heavy use during the Sorland War as the mainstay of Sorlander and Ringeriker field artillery forces.

Design
The m/51 has a 26-Calibre barrel featuring a double baffle muzzle brake and a semi-automatic vertical sliding-block breech and recoil mechanism mounted above the barrel. The carriage is of a split-trail design with a set of large hinge mounted spades at the end of the spurs. The gun-shield offers a level of protection from muzzle blast for the layer as well as cover from small arms fire should it be employed in a direct fire role in local defense. The ammunition system uses two types of charge, both cased, with one comprising a set of incremental charge bags that can be removed as required and the other being a fixed charge offering the largest propellant load for direct fire and maximum range engagements. It was capable of firing a wide variety of projectiles including but not limited to; High Explosive, High Explosive Rocket Assisted, Illuminating, White Phosphorous Smoke and Binary Chemical.
