A French Army CAESAR artillery system pictured right. These use the Renault Truck Defence “Sherpa 10” chassis.
The French CAESAR 155mm Self Propelled Gun is built on proven artillery systems such as the AMF3 gun, the 155 GCT AUF1 self-propelled gun and the 155 TRF1 towed gun, CAESAR is the optimum combination of their features.Versatility, mobility, easy to operate, combat readiness and survivability are the key features of this new 155 mm/52-calibre weapon system which is fully interoperable with the NATO 39 cal. equipment and 52 cal. JB MoU.
From a mobility and maintenance viewpoint, the self-propelled artillery systems are penalized both by their weight and their tracked chassis.Towed guns are disadvantaged in terms of manœuvrability and survivability by their size and their design. The genuinely versatile CAESAR as to it, fills the gap with the innovative solutions it offers and meets the operational requirements, whatever the conflict level, the theatre of operations and the nature of forces involved.
CAESAR can support all types of motorised, mechanised and armoured units, including rapid deployment forces.
CAESAR offers enhanced firepower through quicker response, longer range and improved accuracy. It covers larger areas with fewer guns and favours initiative, manœuvring and quick reaction time while minimizing risks.
CAESAR is effective in each fire mission such as: direct support fire, in-depth action fire, counterbattery fire and even in coastal defence missions.

The French CAESAR 155mm Self Propelled Gun Operators & Combat History
Denmark – The Danish Army was in the process of acquiring 12 to 18 Archer Systems, but due to budget cuts the order has been cancelled. French papers reported during 2012 that Denmark “will definitely acquire 18 Systems (CAESAR’s) in a contract of around 90 million euros”.
France – The first 5 CAESAR artillery systems were delivered during 2000, the second delivery of 8 was made on Wednesday the 16th July 2008. The French Army now operates a total of 77 CAESAR SPG’s. French Army CAESAR artillery systems use a Renault Defence Trucks Sherpa 10 chassis.
The French Army/Marines have deployed 8 CAESAR® artillery systems in Afghanistan since 2009.
Indonesia – 37 have been ordered (using a Unimog 6×6 chassis). The first delivery was completed in September 2012.
