AMOS or Advanced Mortar System is a Finno-Swedish 120 mm automatic twin barrelled, breech loadedmortar turret. AMOS has been fitted to a wide range of armoured vehicles, such as the Sisu Pasi, Patria AMV and Combat Vehicle 90. The Swedish Navy originally planned to fit AMOS to the CB90 assault craft, but found that it was too small to carry it. Instead, a project to develop the larger Combat Boat 2010 was launched specifically to carry AMOS. Sweden cancelled its acquisition of the AMOS in 2009 due to budget regulations by recommendations from Genomförandegruppen. In 2016 a new self propelled mortar system called Mjölner based on a CV90 hull was ordered by the Swedish armed forces, it is based on the AMOS and has many visual similarities but is not as advanced.
