The company is marketing the ATMOS SP artillery system integrated onto a variety of 6x6 (here shown on a Tatra chassis) and 8x8 cross-country chassis using a connector mounted to the rear of cab. It is available with a standard unprotected cab, or an optional fully protected cab equipped with air conditioning and an NBC system.
The ATMOS being shown here is fitted with 155mm/ 52 calibre ordnance with a 23-litre chamber, which meets the NATO Joint Ballistic Memorandum of Understanding (JBMoU).
The maximum firing range depends on the projectile/charge combination, but when firing a 155mm high-explosive base bleed projectile, a maximum range of 41km is achieved. A shorter range of 24km is obtained when firing the older 155mm M107 high-explosive projectile.
A semi-automatic loading system is fitted, which includes a flick rammer enabling a high rate of fire of up to six rounds a minute to be achieved, as well as reducing crew fatigue. The number of 155mm projectiles and associated charges carried is typically about 27. ATMOS can also be supplied with a 18 155mm/39 or 155mm/45 calibre ordnance.
The artillery system is fitted with an onboard computerised fire control system coupled to an inertial navigation system, which allows for autonomous operations, as well as enabling ‘shoot and scoot’ tactics to be used.
ATMOS has been sold to a number of countries, including Uganda, although this has not been confirmed by Soltam Systems.
