The Mjöllnir fire support tank is designed to provide mobile fire support to mechanised battle groups.
The Mjöllnirs main weapon system is a dual mode EMA/electro thermal 155mm cannon. This advance gun system has two fire modes.
In Fire mode 1 the projectile is fired buy converting a small amount of hydrogen to plasma to fire like a conventional gun. this mode has relativly low recoil and a max range of 5 km direct fire or 8 km indirect fire. this mode can be used while the tank is under way.
Mode 2 requires the tanks track units to spread to provide a more stable base to absorbe the greater recoil of the dual boost mode. inital velocity is provided but the elecrothermal system and then the projectile is boosted to 10Km/s by a helical railgun. this mode can only be fire when the tank is stationalry and in deployed mode. it has Line of site range in direct fir mode and 25 km range in indirect fire mode. this mode can deliver a shell withthe same energy as a tactical nuke.
The Mjöllnir also carries a rack of softnose missels for antiair use and a pair of self deffence machine guns.
