Finnish technology firm Varjo has launched a new line of mixed reality (MR) headsets for defense and security training.
The updated lineup includes the XR-4 Secure Edition and XR-4 Focal Edition, both designed for high-fidelity simulation environments. This expands the company’s XR-4 Series to meet military training needs across air, land, and sea operations.
The headsets feature upgraded sensors, improved comfort for extended sessions, and variants certified for use in secure or radio-silent facilities.
Other enhancements include autofocus passthrough cameras, better low-light performance for night operations, and a reinforced design for field use.
Varjo said the new models offer a more realistic and secure platform for training programs that combine physical and virtual environments. The headsets are compatible with existing defense simulators, including those used in aviation and armored vehicle systems.
“We have worked closely with our simulation and training customers to understand the needs of broad-scale deployment, and the refreshed XR-4 Series is the result of that collaboration,” Varjo Chief Product Officer Patrick Wyatt said.
Mixed Reality Gains Ground in Military Training
The launch comes as armed forces worldwide increase investment in mixed and extended reality technologies to enhance training and mission readiness.
The US Army has adopted Varjo’s XR-3 headsets for its Reconfigurable Virtual Collective Trainer program, which allows helicopter crews to train together using simulated controls and immersive visuals.
The system enables pilots to rehearse missions in realistic conditions without relying on full-scale aircraft simulators.
In Europe, mixed reality systems are being integrated into both flight and ground vehicle training.
The Finnish Air Force has incorporated MR tools into its Live-Virtual-Constructive training framework to allow pilots to combine live flying with virtual elements.
Meanwhile, a Czech-developed simulator equipped with MR technology has been used to train Ukrainian pilots on F-16 aircraft.
