An antiquated weapon that fires anti-armor rounds at a low rate of fire, muzzle velocity, and range. Its low flux buildup is a lone saving grace.
The weapon blueprints for Light Mortars actually did not intend them for spacecraft at all, but an ingenious modification to the breech loading mechanism permits installation and use outside an atmospheric environment. In combat, there is little the Light Mortar can do versus moving or shielded targets due to its terrible mount rotation and rate of fire. Nonetheless, it is often used for training novice gunnery officers in the finer points of space ballistic tactics and nomenclature.
Commonly fitted on private yachts and solo interplanetary vehicles because it is so light and cheap.
The Light Mortar is a small ballistic weapon firing explosive rounds. It has the lowest OP cost of any non-missile weapon in the game.
