ATMOS 2000

   The ATMOS 2000 (Autonomous Truck MOunted howitzer System) self-propelled gun-howitzer was developed by Soltam as a private venture. Existence of this artillery system was revealed in 1999, however official details were released only in 2001. This SPH is aimed mainly at the export market. In 2003 an undisclosed export customer ordered an undisclosed batch of these artillery systems. The ATMOS 2000 began trials with the Israeli Defence Forces in 2006.

   The ATMOS 2000 is armed with a 155-mm / L52 gun-howitzer, which is compatible with all standard 155-mm NATO ammunition. The ATMOS 2000 is also available with shorter Soltam 155-m / L39 and 155-mm / L45 barrels. This artillery system can also be fitted with a Soviet M-46 130-mm gun. The standard 155-mm / L52 howitzer was developed from the Soltham ATHOS 2052 towed howitzer, fitted with a load assisting system. Maximum range of fire is 41 km with rocket assisted projectile, and 30 km firing standard HE projectile. Vehicle carries a total of 32 projectiles and associated charges. Rate of fire is between 4 and 9 rounds per minute.

   Advanced fire control system of the ATMOS 2000 receives target information from forward observers. It includes navigation and aiming systems and ballistic computer.

   Vehicle is normally operated by a crew of four, including two loaders. Cab of the ATMOS 2000 is armored and protects the crew from small arms fire and artillery shell splinters.

   The ATMOS 2000 uses Tatra T815 VVN 6x6 truck chassis. Vehicle is powered by a diesel engine, developing 315 hp. An auxiliary power unit is fitted, which prepares vehicle for firing, operates weapon elevation and traverse and powers the load assisting system when the main engine is shut down. Howitzer can be operated manually in case of emergency. This artillery system can be airlifted with a C-130 Hercules medium transport aircraft.
