PARIS — March 26, 2026 : Thales has introduced the Expeditionary PathMaster, a mission capability package designed to support naval forces transitioning toward hybrid mine warfare operations that integrate both crewed and uncrewed systems. The package consolidates the company’s existing naval mine warfare technologies into a modular, scalable framework that can be deployed and made operational within approximately six months.
System Architecture and Core Components
The Expeditionary PathMaster is built around a “building block” approach using three primary components:
-
e-POC (expeditionary portable operations centre): A transportable hardware solution that enables deployment of command-and-control capabilities in compact or distributed environments.
-
M-Cube: A mission management system responsible for coordinating assets and generating a unified operational picture.
-
Mi-Map: A sonar data analysis software designed for detection, classification, and localisation of underwater objects.
This modular configuration allows navies to scale the system from a compact setup—such as a three-screen laptop configuration—to a full command centre. The system is hardware-agnostic and can be deployed from shore facilities, rigid inflatable boats, minehunters, or other available platforms.
Operational Concept and Interoperability
The system is designed to support hybrid mine countermeasures (MCM) operations by integrating crewed vessels, legacy platforms, and uncrewed systems into a single operational framework. It supports autonomous and remotely operated uncrewed underwater vehicles (UUVs), including third-party systems.
The architecture enables navies to incorporate existing assets or nationally prioritised systems without requiring full fleet replacement. Beyond mine clearance, the package can also support tasks such as anti-submarine warfare (ASW), extending its operational utility.
Thales states that the system provides full MCM mission capability, including securing critical undersea infrastructure and supporting expeditionary and amphibious operations.
Data Processing and Artificial Intelligence Integration
Mine countermeasure operations rely on acoustic mapping of the seabed to identify anomalies. The classification stage—distinguishing potential mines from environmental noise—is identified as the most complex phase of operations.
Modern high-resolution sonar systems, particularly those deployed on uncrewed platforms, generate large volumes of data. To manage this, Thales has integrated its cortAIx artificial intelligence accelerator into the system.
When combined with M-Cube and Mi-Map, cortAIx enables:
-
Parallel processing of multiple sonar analysis sessions
-
Real-time data updates and decision support
-
Up to fourfold increase in sonar data processing speed
-
Approximately 99 percent accuracy in target classification under operational conditions
These capabilities are intended to reduce operator workload and accelerate decision-making, particularly in time-sensitive scenarios such as reopening ports or securing maritime routes.
Development Background and Operational Testing
The Expeditionary PathMaster concept is derived from existing systems already in service or under evaluation with several navies. Its development incorporates operational feedback from France, Japan, Singapore, and the United Kingdom.
A key contributor to its evolution has been the France/UK Maritime Mine Counter Measures (MMCM) programme, where Thales serves as the industrial prime contractor. Data from this programme highlighted the importance of coordinating multiple uncrewed assets simultaneously and improving situational awareness for faster operational decisions.
Demonstrations and Deployment Milestones
Several demonstrations and deployments of the system’s components and integrated package have been conducted:
-
France and the United Kingdom: The e-POC, M-Cube, and Mi-Map components have been delivered to the French Navy (Marine Nationale) and the Royal Navy for qualification and operational exercises.
-
Third-party integration: Successful interoperability has been demonstrated with systems such as the A27 UUV and REMUS 600 UUV.
-
Command centre scaling: The French Navy is using expanded e-POC configurations integrated with M-Cube and Mi-Map within its MCM command centres.
-
Lithuania: The Lithuanian Navy tested the complete Expeditionary PathMaster package, demonstrating rapid integration of UUV operations with existing minehunters.
-
NATO exercises: System components have been employed in Allied Maritime Command (MARCOM) exercises.
Additionally, the e-POC system had previously been supplied as a demonstrator to the French Navy in 2024, where it enabled simultaneous control of up to three UUVs from a compact setup transportable in six cases.
Role Within the PathMaster Family and Broader Context
Expeditionary PathMaster forms part of Thales’ broader PathMaster family of mine countermeasure solutions, which includes uncrewed surface vehicles and towed synthetic aperture sonar systems such as SAMDIS. Elements of this ecosystem have been selected by navies including Singapore.
The MMCM programme continues in production, supplying systems to both the French and UK navies, with Expeditionary PathMaster building on this operational foundation.
Implementation and Force Development
The modular design is intended to support incremental adoption, particularly for navies introducing uncrewed capabilities for the first time. By allowing flexible scaling of system components, the package supports affordability and phased capability development.
In addition to operational deployment, the system is designed to assist navies in adapting doctrine, organisational structures, equipment management processes, and personnel training to accommodate hybrid operational models.
Thales indicates that the Expeditionary PathMaster is available for procurement as a complete package, although it is currently awaiting formal supply contracts in this configuration.
