Plexsys and BAE Systems OneArc have entered into a strategic Memorandum of Understanding (MoU), establishing a formal commitment to deeper technical integration and collaborative development in defence training systems.
The MoU was signed on the first day of I/ITSEC 2025 in Orlando, Florida.
It establishes a framework for closer collaboration between the companies, focusing on advancing interoperability and coordination in the delivery of Live, Virtual, and Constructive (LVC) training systems to military users globally.
The companies plan to integrate Plexsys’ Advanced Simulation Combat Operations Trainer (ASCOT) 7 environment generator with OneArc’s VBS4 synthetic training platform to provide unified scenario generation and enhanced visualisation across air, land, maritime, space, and cyber domains.
According to the agreement, Plexsys and OneArc intend to streamline training workflows for military customers by simplifying integration and minimising friction between tools.
The collaboration will also look at aligning future product development to ensure ongoing compatibility as new features are introduced.
Plexsys chief operations officer Dr. Hart Rutherford 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.”
Plexsys has provided LVC training solutions to defence customers for over three decades. Its ASCOT 7 environment generator forms the basis for modelling complex operational scenarios, supported by distributed communications and mission analysis tools.
OneArc supplies synthetic environments through its VBS4 platform, which is used by armed forces worldwide to support a range of military training scenarios on virtual desktops.
OneArc strategic growth and partnerships senior director Jenna Tuck 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, multi-domain training solutions for our warfighters – across domains and borders.”
