The new 6×6 configuration of the ATMOS was designed to address the Thai Army requirements
A new version of Elbit Systems’ Autonomous Truck Mounted howitzer System (ATMOS) 155 mm/39-calibre SP artillery system was developed for the Royal Thai Army (RTA), in cooperation with Thailand’s military industrial complex. A first unit comprising six CAESAR 155mm/52 caliber guns is currently in service. The ATMOS platform is designed to operate the 155mm/52 caliber tube, but in Thailand the Army opted for the 155mm/39 caliber howitzer using a 6×6 truck. The ATMOS has already been demonstrated implemented on 8×8 trucks, carrying 54 caliber guns.
According to Jane’s Defense Weekly, the SPGs will be produced at the Thai Army Artillery and Mortar Production Division of the Royal Thai Army’s (RTA’s) Weapon Production Centre (WPC). The locally produced guns are expected to be delivered by the military factory in 2015.
As an autonomous weapon platform ATMOS integrates a highly sophisticated and accurate navigation and positioning system, comprising an inertial navigation system, global positioning and on-board firing computer offering maximum flexibility and efficiency. Automated ammunition loading system to accelerate firing series and minimize the exposure of the gun in the firing position.
