New 155mm Howitzer From Calidus at IDEX 2025 with Enhanced Mobility and Firepower.
At IDEX 2025 in Abu Dhabi, Calidus Land Systems introduces the LAHAB, a new self-propelled artillery system designed to meet the evolving needs of modern warfare. Developed to enhance long-range fire support, this 155mm howitzer combines advanced mobility, rapid deployment, and firepower, providing armed forces with a highly responsive and adaptable artillery solution. The unveiling of the LAHAB marks an important step in the United Arab Emirates' strategy to strengthen its domestic defense industry while positioning Calidus as a key player in the global defense market. By integrating a new turret onto a proven chassis, the system ensures compatibility with NATO standards, making it a viable option for both regional and international militaries.

The LAHAB features a 155mm, 52-caliber gun, capable of engaging targets up to 56 kilometers away, depending on the ammunition type used. The system's automatic loader enables a firing rate of up to eight rounds per minute, ensuring sustained fire support in high-intensity conflicts. Additionally, it is designed for multiple-round simultaneous impact (MRSI) capability, allowing the delivery of coordinated salvos on multiple targets.
The combat autonomy of the system is enhanced by its integrated loader, which holds 28 ready-to-fire shells, complemented by 22 additional rounds in reserve. This configuration reduces the need for frequent resupply, increasing the system’s endurance in prolonged operations. A key operational advantage of the LAHAB is its ability to transition quickly between movement and firing, with a setup time of less than one minute. This enables quick repositioning, minimizing exposure to counter-battery fire and improving survivability on the battlefield.
The system is built on a durable and highly mobile chassis, designed to support a gross vehicle weight of 36 tons. A 724-horsepower engine powers the LAHAB, ensuring optimal performance across a range of terrains.
Its automatic seven-speed transmission, combined with a central tire inflation system, allows for seamless adaptability in challenging combat environments, enhancing stability and maneuverability. Designed for seamless battlefield integration, the howitzer is equipped with advanced communication systems and a battlefield management system, enabling real-time coordination with other military assets.
The protection and survivability of the LAHAB align with STANAG 4569 standards, offering resistance against ballistic threats and improvised explosive devices. The engine compartment and crew cabin are safeguarded by an automatic fire suppression system, which reduces the risks associated with mechanical failures or direct attacks.
Additionally, a chemical, biological, radiological, and nuclear protection system ensures the crew’s safety in contaminated environments. To reinforce close-range defense capabilities, the LAHAB can be fitted with a 12.7mm machine gun, available in both manually operated and remote-controlled weapon station configurations. Furthermore, smoke grenade launchers enhance tactical concealment, allowing the system to evade enemy observation and targeting.
The development of the LAHAB reflects the UAE’s long-term vision of reducing reliance on foreign defense suppliers while building a sustainable and competitive military industry. While the primary focus remains on equipping local forces, the system’s modular architecture and NATO compatibility provide a strong foundation for potential exports.
The LAHAB is expected to attract interest from nations seeking to modernize their artillery forces with highly mobile, long-range fire support solutions. Its ability to operate in diverse combat scenarios positions it as a valuable asset for militaries requiring versatile, rapid-deployment artillery systems. By leveraging existing platforms and introducing a new turret system, Calidus has created a cost-effective and adaptable solution that meets the demands of contemporary and future battlefields.
