CAESAR is a French 155 mm/52-caliber truck-mounted howitzer family fielded in 6x6, protected Mk2, and 8x8 configurations. Its rapid displacement, NATO 155 mm ammunition compatibility, and guided-projectile options made it a widely exported mobile artillery system documented in Ukraine, Mali, Yemen, and coalition operations against the Islamic State.
SIPRI records French-supplied CAESAR 155 mm deliveries to Ukraine beginning with 18 second-hand guns in 2022 and 12 more in 2023, plus 19 new CAESAR-2 systems originally ordered by Denmark and delivered in 2023 with Danish financing; Danish forces trained Ukrainian crews, drivers, and mechanics, and Ukrainian official material documents rapid fire missions and displacement under drone and counter-battery pressure.
Role detailsThe CAESAR-equipped 68e régiment d'artillerie d'Afrique was deployed to Mali in Operation Serval and then Operation Barkhane, giving French and partner forces long-range artillery support in the 2012 Mali War.
Saudi CAESAR howitzers were documented on the Saudi-Yemeni border in 2018, positioned to support coalition and loyalist ground operations into Yemeni territory.
Role detailsFrench Task Force Wagram operated CAESAR guns from Iraq as coalition fire support against Islamic State forces, including missions from Mosul to Baghouz.
Role detailsCAESAR's Ukraine record combines state-to-state artillery transfers, fast crew conversion, and battlefield use in a counter-battery environment shaped by drones and electronic warfare.

CAESAR began as a fast export-minded answer to the limits of tracked French artillery, combining a 52-caliber gun with a truck chassis and a low-cost, rapidly deployable architecture.
| Design point | Evidence | Why it matters |
|---|---|---|
| Name | CAESAR expands from CESAR, with the extra A added for Camion. | The acronym itself points to the truck-mounted concept. |
| Prototype | The prototype was completed in less than a year and shown at Eurosatory in 1994. | The program moved quickly from concept to public demonstration. |
| Transport | The original requirement called for C-130 transport in one load, including the gun crew and three salvos of six rounds. | It was designed for expeditionary fire missions and fast displacement. |
The public CAESAR family is split mainly between the original 6x6 system, the protected 6x6 Mk2 modernization, and the heavier 8x8 configuration.
| Variant | Configuration | Designation notes |
|---|---|---|
| CAESAR 6x6 Mk I | Baseline 6x6 truck-mounted howitzer | The original 6x6 system entered French Army service in 2008 after development from the earlier 1994 prototype and export-focused truck-gun concept. |
| CAESAR 6x6 Mk II | Protected and uprated 6x6 modernization | Mk2 development began in December 2021, and the 2024 French order describes a protected cabin, 460 hp engine, automatic gearbox, and updated fire-control and communications package.

| CAESAR 8x8 | Heavier export 8x8 configuration | The 8x8 version uses a four-person crew, semi-automated loading, and a larger onboard ammunition load than the 6x6 family. Sources: CAESAR 8x8 |
KNDS lists CAESAR 6x6 Mk2 as compatible with NATO standard 155 mm ammunition and multiple guided or sensor-fuzed artillery projectiles.
| Ammunition | Ammunition type | Firing evidence |
|---|---|---|
 | Standard 155 mm ammunition | The KNDS CAESAR 6x6 Mk2 sheet says the gun fires all 39/52-caliber NATO standard and ERFB rounds. Sources: CAESAR 6X6 MK II |
 | Guided artillery projectile | KNDS lists Excalibur among CAESAR 6x6 Mk2 smart ammunition options and gives an Excalibur range figure for the system. Sources: CAESAR 6X6 MK II, CAESAR Mk2 |
 | Sensor-fuzed projectile | KNDS lists BONUS among CAESAR 6x6 Mk2 smart ammunition options. Sources: CAESAR 6X6 MK II, CAESAR Mk2 |
The CAESAR page benefits from treating the gun family and its ammunition envelope together: the chassis changed across 6x6, Mk2, and 8x8 versions, while the 155 mm/52-caliber ordnance remained the basis for standard and smart ammunition compatibility.
| Module | Documented details | Reader value |
|---|---|---|
| 6x6 Mk2 | Protected cabin, 460 hp engine, automatic gearbox, A400M transportability, 18 complete rounds. | Explains why the Mk2 is a survivability and mobility update rather than a new caliber. |
| 8x8 | Four-person crew, semi-automated loading, and 36 onboard rounds. | Separates the heavier export variant from the air-transportable 6x6 family. |
| Smart ammunition | KNDS names Excalibur, BONUS, KATANA, and Vulcano among smart options for CAESAR Mk2. | Shows why the gun is relevant beyond conventional high-explosive 155 mm fire. |
CAIA says the prototype was built in less than a year and displayed at Eurosatory in 1994.
