Press Release, Helsinki, 08 October 2025: [embargoed until 07:00 BST] Varjo, the technology leader in military-grade virtual and mixed reality solutions, today announced a refreshed XR-4 Series, the first mixed reality headsets engineered to support mission-ready training across air, land, and sea. The refreshed model is purpose-built to close the gap between traditional simulation methods and the demands of modern training.
Originally launched in 2023, the XR-4 Series headsets are optimised to be integrated into cockpit trainers, vehicle simulators, or ground training systems, addressing the growing global need for scalable, safe, and realistic training. The compact form factor of the XR-4 Series allows complete systems to be transported for rapid deployment to training points of need around the world.
“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,” said Patrick Wyatt, Chief Product Officer at Varjo. “As a trusted partner in over 100 defence and aviation programmes worldwide, including the US Army’s Reconfigurable Virtual Collective Trainer (RVCT), we are committed to help scale training, enhance operational readiness, and better protect the lives of those who protect ours.”
Compared to the original model, the refreshed XR-4 Series introduces key hardware and software enhancements, including:
- Fit and comfort for demanding training – A redesigned headband and slimmed rear counterweight ensure stability and comfort during pilot training or ground vehicle simulations. An optional chin strap is now available for added headset stability during dynamic exercises. A new front plate compatible with SteamVR tracking improves physical robustness.
- Deployment-ready mixed reality for cockpits – Optimised autofocus passthrough cameras allow pilots to interact with real maps, checklists, and avionics inside real cockpits while remaining fully immersed in a simulated environment. Advanced hand occlusion allows users’ real hands to blend naturally with virtual objects and environments. A dedicated night mode allows simulating nighttime operations realistically. A new headset adapter incorporates advanced retimer to improve signal quality, delivering up to 99.9% reduction in packet loss for uninterrupted training. Varjo also pioneers AI-improved passthrough with gaze prediction capability to further enhance immersion and reduce system load during high-intensity simulations.
- Long-term operational support for large-scale deployments – Varjo backs the XR-4 Series with guaranteed hardware and software support through 2030, along with professional services for deployment planning, fleet provisioning, and on-site integrations.
Additionally, the devices carry over all the advanced mixed reality features of the XR-4 Series, including ultra-high-resolution visuals with 51 pixels per degree, 120° x 105° field of view, and 20+ mega-pixel stereo passthrough. Their tethered Windows-based architecture ensures compatibility with the graphics-intensive image generators and simulation software already in use by armed forces worldwide. One of the variants, the XR-4 Secure Edition, is manufactured in Finland, a NATO member state, and offered in TAA-compliant configurations with no wireless components for deployment in classified environments.
