The agreement formalises a long-standing relationship between the two companies and sets the foundation for deeper technical integration, co-development, and collaborative engagement with customers worldwide. It comes at a time when demand for integrated synthetic training is accelerating exponentially, driven by shifting operational requirements and the growth of multidomain training needs.

 
For more than 35 years, PLEXSYS has delivered trusted Live, Virtual, and Constructive (LVC) training solutions to defence users globally. Its Advanced Simulation Combat Operations Trainer (ASCOT) 7 environment generator, combined with PLEXSYS’ distributed communications and mission analysis tools, provides a mature and scalable foundation for modeling complex operational environments.
 
OneArc is a global defence tech innovator delivering synthetic environments to transform how we simulate the modern battlespace – at speed and scale. Its flagship VBS4 platform offers a comprehensive virtual desktop training environment that enables the creation and execution of any imaginable military training scenario, used by forces worldwide.
 
Together, PLEXSYS and OneArc are offering complementary solutions that enhance how forces plan, execute and review mission-focused training.
 
The MoU reinforces this alignment. ASCOT 7 acts as the scalable, multidomain 'engine' generating complex activity across air, land, maritime, space and cyber domains, while VBS4 enhances the dynamic visualisation of that environment – supporting both individual and collective training use cases. By expanding their integration, PLEXSYS and OneArc can offer a more seamless experience across scenario generation, visualisation and mission execution. For military users, the collaboration aims to simplify integration, reduce friction between tools and deliver more cohesive training workflows.
 
The MoU also outlines plans for the two companies to deepen their technical integration, develop capabilities that reflect real operational needs and coordinate more closely on where their combined tools can benefit customers. The two sides will also stay aligned on future product plans, ensuring continued compatibility and smooth integration as new features and capabilities are introduced.
 
Dr Hart Rutherford, Chief Operations Officer at PLEXSYS said: “OneArc’s platforms and our environment generator already work together within many customer ecosystems and this MoU allows us to take that collaboration even further. By aligning technical roadmaps and deepening integration, we can deliver training experiences that are more immersive, more interoperable and more operationally relevant. We look forward to what this next phase of collaboration will achieve.”
 
Jenna Tuck, Senior Director for Strategic Growth and Partnerships at OneArc said: “As militaries prepare for increasingly complex all-domain missions, partnerships like this are essential. Working more closely with PLEXSYS strengthens our ability to deliver scalable, multidomain training solutions for our warfighters – across domains and borders.”
