ATMOS 2000

ATMOS, short for Autonomous Truck Mounted howitzer System, is a 155 millimetre self-propelled gun that mounts a 52 calibre barrel on a six by six cross-country truck chassis. It was developed by the Israeli firm Soltam Systems as a private venture aimed mainly at export customers, and Soltam has been wholly owned by Elbit Systems since 2010. A crew of four serves the gun, which carries 27 projectiles with their charges and fires between four and nine rounds a minute. With extended range base bleed shells its maximum range reaches 41 kilometres, and barrel lengths from 39 up to 52 calibres are offered to suit different buyers. Derivatives include the Thai M758 ATMG on a Tatra chassis, while the Polish Kryl and the Romanian ATROM never reached production. Operators range from Azerbaijan and Cameroon to Denmark and the Philippines.
