BERLIN : Germany, France, Britain, Italy, Poland and Sweden have signed a strategic agreement to jointly develop and manufacture a long-range loitering munition system with a range of 500 kilometers. The agreement was concluded in Berlin on February 12, 2026, on the margins of a NATO defense ministers’ meeting held in Brussels.
The initiative is being pursued under the European Long Range Strike Approach (ELSA), a multinational framework established to address a recognized capability gap in conventional deep-strike systems across Europe.
Program Structure and Design Concept
The project, informally referred to in expert circles as the One Way Effector 500 Plus (OWE 500+), is intended to produce a shared, high-capacity loitering munition platform with provisions for national customization.
The first phase of the program will consist of a feasibility study focused on developing a common airframe. The baseline design will allow participating nations to integrate their own payloads and guidance systems while retaining overall platform standardization. This modular structure is intended to reduce development costs and streamline multinational procurement.
A distributed production model has been adopted. Manufacturing activities will be spread across multiple partner countries to strengthen industrial resilience and enable rapid scaling of output. Officials involved in the program have indicated that this decentralized approach is designed to mitigate supply chain vulnerabilities and prevent production bottlenecks should any single manufacturing site become unavailable.
Cost Framework and Warhead Concept
One of the key objectives of the OWE 500+ program is cost reduction compared to traditional cruise missile systems. Reports associated with the project indicate a targeted unit price in the five-digit range. This pricing objective is significantly lower than conventional cruise missile costs and is intended to allow procurement in substantial quantities.
To support cost efficiency, one leading proposal under consideration involves using conventional 155mm artillery shells as the primary warhead component. This approach would leverage existing ammunition inventories and established production lines within Europe.
The system is expected to deliver a 50-kilogram payload with precision engagement capability across its full 500-kilometer operational range.
Operational Role and Technical Characteristics
The OWE 500+ is being designed primarily for use in saturation operations. Military planners envision deploying large numbers of these munitions simultaneously to challenge and exhaust adversary integrated air defense systems (IADS).
Unlike smaller tactical unmanned aerial systems that require continuous manual control, the OWE 500+ will incorporate onboard intelligence sufficient to autonomously navigate to designated coordinates and engage assigned targets. The autonomy features are intended to reduce operator workload and increase deployment flexibility.
Program planning documents indicate that a single operator is expected to be capable of managing a double-digit number of effectors simultaneously. This operational concept emphasizes scalability and coordinated mass employment.
German Army Integration Plans
For Germany, the OWE 500+ is linked to ongoing restructuring within the land forces. According to Ministry of Defense sources, the munition will be integrated into the Army to provide ground-to-ground precision strike capability at extended ranges.
The integration aligns with a 2024 announcement by Lieutenant General Christian Freuding, Inspector of the Army, concerning the establishment of a future Multi-Domain Task Force structure.
Berlin intends to establish its first long-range precision-agent battery by 2029. In addition, Germany has reportedly committed to providing NATO with three such batteries in the coming years as part of alliance capability contributions.
Alignment With Broader European Efforts
The six-nation agreement under ELSA follows related national initiatives. France recently signed an initial contract with MBDA for a sovereign version of a One-Way Effector system. The multinational OWE 500+ program is expected to harmonize such national efforts and support interoperability among participating European armed forces.
Officials involved in the project state that the collaboration aims to standardize key technical elements while allowing sufficient flexibility for national requirements. The feasibility phase will define technical parameters, industrial roles and procurement pathways before proceeding to full development and production.
The OWE 500+ program represents a coordinated European effort to expand long-range conventional strike capacity through a modular, distributed and cost-controlled development model.
