Fire-on-the-Move Artillery

Revolutionary Mortar Technology Sets New Standards for Battlefield Mobility

Finnish defense technology company Patria has established itself as the global market leader in turreted mortar systems with its Patria NEMO (NEw MOrtar) platform, a revolutionary 120mm remote-controlled mortar system that fundamentally changes how modern armed forces approach indirect fire support. This advanced weapon system combines mobility, protection, and precision in a compact package designed specifically for the tempo and complexity of contemporary warfare environments.

The Patria NEMO mortar system represents a significant evolutionary step in artillery technology, addressing one of modern warfare’s most critical challenges: how to deliver overwhelming firepower while maintaining survivability in an era where detection technologies can pinpoint firing positions almost instantaneously. Unlike traditional mortar systems that require crews to stop, deploy, fire, and withdraw, the NEMO platform delivers genuine fire-on-the-move capability, allowing operators to engage targets while the vehicle remains in motion.

This unique operational flexibility stems from sophisticated ballistic calculation systems that compensate for vehicle movement in real-time, ensuring accuracy even when firing from moving platforms. The system can deliver Multiple Rounds Simultaneous Impact (MRSI) missions, placing up to five rounds on target simultaneously, and Multiple Targets Simultaneous Impact (MTSI) capabilities, enabling engagement of multiple objectives with coordinated timing.

Technical Excellence Through Modular Design

At the core of the Patria NEMO mortar system lies a single-barrel 120mm smoothbore mortar housed within a fully remote-controlled turret weighing approximately 1,900 kilograms. This relatively lightweight configuration enables integration across a diverse range of platforms, from 6×6 wheeled armored vehicles to 8×8 configurations, tracked chassis, and even naval vessels.

The turret provides complete 360-degree traverse with elevation ranging from minus three degrees to plus 85 degrees, offering both indirect fire capabilities and direct fire options for self-defense scenarios. This dual-capability approach ensures crews can respond to threats across the entire tactical spectrum without exposing themselves to hostile fire.

Protection represents a fundamental design priority throughout the NEMO platform. The turreted configuration keeps crew members under armor at all times, eliminating the need to open hatches during operations. This enclosed environment protects operators from ballistics, mine and IED threats, battlefield contaminants, weather conditions, and the dangerous overpressure and noise associated with firing operations.

Ammunition safety features include individual tube storage for each round, with fire and gas venting systems that direct any accidental ignition through external chimneys, preventing crew exposure and containing the risk of catastrophic secondary explosions. The system maintains large onboard ammunition supplies, with typical configurations carrying 50 to 60 rounds of 120mm ammunition depending on the host platform.

Network-Centric Warfare Integration

The Patria NEMO mortar system exemplifies network-centric warfare principles through comprehensive sensor-to-shooter integration. The platform’s advanced fire control system enables seamless connection with tactical data networks, command and control systems, and forward observer functions, creating a unified ecosystem for identifying targets and executing fire missions with minimal latency.

Engagement decisions made at fire direction centers transmit directly to NEMO units through these networks, with the system automatically calculating firing solutions based on target data, meteorological conditions, and ammunition characteristics. This automation significantly reduces the time from target acquisition to rounds on target, a critical advantage in fast-moving operational environments.

The forward observer system integrated into the NEMO ecosystem provides comprehensive battlefield awareness, enabling operators to identify targets, assess damage, and adjust fire missions in real-time. Tactical weather services feed current atmospheric data into ballistic calculations, ensuring maximum accuracy across varying environmental conditions.
