Transatlantic Co-Production Framework for Precision-Guided Artillery Munitions

Rheinmetall and General Atomics Electromagnetic Systems signed a Memorandum of Understanding on 18 June 2026 at the Eurosatory defense exhibition in Paris, France, to explore the co-production of a maneuvering 155 mm precision-guided munition. This technical cooperation targets the modernization and stockpile replenishment of alliance artillery forces within high-intensity operational environments.

Industrial Challenges and Cooperation Rationale
Modern military logistics face expanding requirements for scalable manufacturing and long-range standoff capabilities as governments rebuild depleted ammunition inventories. Traditional guided-munition output struggles to match accelerating operational demand, creating a critical integration challenge for coalition force structures. Addressing this scale and complexity requires a distributed co-production framework that combines complementary technical expertise. General Atomics Electromagnetic Systems provides specialized engineering in precision-strike munition development and scalable design, while Rheinmetall delivers automated production lines and NATO-compliant manufacturing infrastructure.

Technical Solution and System Interoperability
The cooperative solution focuses on a maneuvering projectile designed to interface directly with existing 39- and 52-calibre artillery systems. At a system level, the architecture incorporates a glide-based aerodynamic design utilizing pop-up high-aspect-ratio wings to extend engagement ranges two to three times beyond conventional unguided projectiles. Because the system relies on an unpowered glide mechanism rather than propulsive rocket motors, it optimizes the internal volume of the shell casing cavity for high-explosive payloads while maintaining structural integrity against extreme gun-launch stresses. For operation in contested and GPS-degraded environments, the onboard guidance suite integrates multi-sensor telemetry layers, including inertial navigation, GPS, and optical terrain-referencing, to execute precise mid-course trajectory corrections.

Deployment and Functional Use Cases
The deployment strategy enables rapid integration across fielded artillery formations without requiring modifications to existing launcher systems, propellant inventories, or tactical logistics infrastructure. By integrating add-on guidance logic directly into a standard form factor, the system functions as a lower cost-per-effect alternative to tactical missile systems. This modular approach simplifies lifecycle maintenance and ensures compatibility with automatic gun loaders across diverse self-propelled and towed howitzer fleets, directly enhancing process stability and fleet maintainability during field deployment.
