AMOS has been fitted to a wide range of armoured vehicles, such as the [Sisu Pasi](/source/Sisu_Pasi), [Patria AMV](/source/Patria_AMV) and [Combat Vehicle 90](/source/Combat_Vehicle_90). The [Swedish Navy](/source/Swedish_Navy) originally planned to fit AMOS to the [CB90](/source/CB90) assault craft, but found that it was too small to carry it. Instead, a project to develop the larger [Combat Boat 2010](/source/Combat_Boat_2010) was launched specifically to carry AMOS. Sweden cancelled its acquisition of the AMOS in 2009{{Cite web |last=Häggblom |first=Robin |date=2023-05-23 |title=Swedish Marines get shipboard mortars |url=https://www.navalnews.com/naval-news/2023/05/swedish-marines-get-shipboard-mortars/ |access-date=2025-08-11 |website=Naval News |language=en-US}} due to budget regulations by recommendations from [Genomförandegruppen](/source/Genomf%C3%B6randegruppen). In 2016 a new self propelled mortar system called ''Mjölner'' based on a [CV90](/source/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. == Design == thumb|AMOS ammunition storage compartment When fitted to a vehicle, both [GPS](/source/GPS)- and [inertia positioning](/source/Inertial_navigation_system) are used. The electronic [fire-control system](/source/fire-control_system) utilizes [digital maps](/source/Digital_mapping). The twin barreled AMOS is able to keep up rate of fire of 12 rounds per minute. Using its computer-controlled [Multiple round simultaneous impact (MRSI)](/source/Artillery) feature it is possible to set up a burst of up to 10 rounds that hit the target simultaneously.{{Cite web|date=2021-11-03|title=BAE Systems Datasheet|url=http://www.baesystems.se/Hagglunds/Brochure/Amos.pdf|url-status=live|archive-url=https://web.archive.org/web/20061009212354/http://www.baesystems.se/Hagglunds/Brochure/Amos.pdf |archive-date=2006-10-09 }} The first rounds are fired at higher angles with more [propellant](/source/propellant) so that the rounds fly in a high arc. The next rounds are shot later with a slightly smaller angle and less propellant so that they fly a lower arc to the same target. This can be done seven times in a row, always adjusting the angle and power. The adjustment between shots is done by a [computer](/source/computer). The strike of one AMOS unit roughly equals one strike of an [artillery battery](/source/artillery_battery). An AMOS [turret](/source/Gun_turret) has a full 360-degree field of fire at elevations of −3 to +85 degrees. AMOS is capable of both conventional indirect fire and direct fire for self-protection. In a typical installation, mounted on a Patria AMV or a similar vehicle, the vehicle can dash to the next position roughly 30 seconds after initiating the 14-round salvo, leaving minimal time for detection and counter-attack by enemy; evasion is the primary means of self-protection. AMOS is manufactured and marketed by Finnish/Swedish Patria Hägglunds, a joint venture between Finnish [Patria](/source/Patria_(company)) and Swedish [BAE Systems Hägglunds](/source/BAE_Systems_H%C3%A4gglunds). The system was to be known as the '''SSG120''' in Swedish service. [Ammunition](/source/Ammunition) for AMOS includes the [Strix](/source/Strix_mortar_round) guided round and a modification of the Spanish [Instalaza](/source/Instalaza) [MAT-120](/source/MAT-120) 120 mm Mortar Cargo Round (although the latter is restricted from the Finnish inventory because of Finnish partnership in the [Ottawa Treaty](/source/Ottawa_Treaty) abolishing landmines). AMOS is capable of firing standard muzzle-loaded mortar rounds, but due to the breech-load design in the AMOS, the rounds have to be equipped with a short stub case at the base of the fins, similar to a sabot. When the round is fired, the case exits the breech system automatically. ==Operators== thumb|300px|Map of AMOS operators in blue ===Current operators=== * {{flag|Finland}} ** '''18 AMOS''' ordered in 2010, delivered from 2013, all in service {{Cite web |title=CONFIDENCE- AND SECURITY BUILDING MEASURES - VIENNA DOCUMENT 2011 - ANNUAL EXCHANGE OF MILITARY INFORMATION - Finland |url=https://puolustusvoimat.fi/documents/1948673/2014902/CBMFI23.pdf |website=puolustusvoimat.fi}} === Potential orders === * {{flag|Czech Republic}} ** The [Army](/source/Army_of_the_Czech_Republic) is looking for '''62''' self-propelled mortars, capable of indirect, semi-direct and direct fire and most likely on the 8x8 [Pandur II](/source/Pandur_II). The competitors are the [Patria NEMO](/source/Patria_NEMO) and the [M120 Rak](/source/M120_Rak).

It was expected to be installed on the [CV90](/source/Combat_Vehicle_90). In 2016, the Mjölner was selected to take over the role of the AMOS. 80 Mjölner turrets have been ordered so far. ** {{navy|Sweden}} The '''AMOS''' purchase was cancelled in 2009 after studies finding out that fitting it to the [Combat Boat 2010](/source/Combat_Boat_2010) was too expensive. Initially, the [CB90](/source/CB90) was the platform planned, but it was discovered to be too small to carry the AMOS. In 2023, Sweden decided to manufacture such a ship, but with the Patria Nemo as a turret, 8 were ordered.{{Cite web |title=24 M FAST MORTAR - Swede Ship Marine AB - PDF Catalogs {{!}} Documentation {{!}} Boating Brochures |url=https://pdf.nauticexpo.com/pdf/swede-ship-marine-ab/24-m-fast-mortar/36943-106870.html |access-date=2023-05-31 |website=pdf.nauticexpo.com}} ==See also== * {{lwc|Patria NEMO}} * {{lwc|Light-weight combat vehicle }} * {{lwc|M120 Rak}} ==References== {{Reflist}} ==External links== {{Commons category}} * [https://web.archive.org/web/20121120100633/http://www.amos.fi/ AMOS at Patria Hägglunds's website] Rev 7.3.2012 * [https://web.archive.org/web/20120115094444/http://www.patria.fi/Patria_WWW_EN_Sisalto/Patria_WWW_EN/Products+and+services/Mortar+Systems+sitearea/AMOS+Advanced+Mortar+System/index.html AMOS Advanced Mortar System] and [https://web.archive.org/web/20120105114053/http://www.patria.fi/525f30004d9b1426af41af4b69f1ce94/Amos2008.pdf Amos Brochure 2008] at www.patria.fi.
