NEMO (from "new mortar"), is a single barrelled 120 mm unmanned gun-mortar turret currently being developed by Patria Weapons System Oy (PWS) in Finland. It is a lighter version of the AMOS mortar system, which is also being field tested. The NEMO can be fitted to most APCs and also to smaller landing craft, such as the Finnish Jurmo class landing craft or the Swedish Combat Boat 90.


The first customer of the weapon system was the Slovenian Army,[1] which ordered 24, while the United Arab Emirates Naval Forces bought 12 patrol boats, where some were to be equipped with NEMO mortars.[2] Saudi Arabia bought 36 turrets to equip its LAV II vehicles.[3] Recently, Patria is offering the NEMO system fitted into standardised 20-ft-containers to increase flexibility: the mortar container can be lifted with and fired from a truck or a boat or can be set on the ground, e.g. as base defense.[4][5][6] Training simulators are also available.[7]
