Whole-Earth Virtual Desktop Training & Simulation Host

VBS4 provides a comprehensive virtual desktop training environment with whole-earth rendering for tactical training, experimentation, and mission rehearsal, and performs as a powerful simulation host for any IG

What is VBS4?

VBS4 is a whole-earth virtual desktop trainer and simulation host that allows you to create and run any imaginable military training scenario.

The VBS4 workflow steps the user through Prepare - Execute - Assess phases, facilitating fast and effective skills enhancement. In VBS4, users create “Battlespaces” that are a collection of terrain edits, mission plans, scenario files and after-action reviews.

With VBS4, you can plan your mission, build your terrain with easy-to-use interfaces, and focus on the learning points of the exercise rather than the technical aspects of setup.



Edit terrains and collaborate with other users to build terrains with an easy-to-use interface

Facilitate commander training with VBS4’s easy-to-use mission planning tool

Create complex scenarios with VBS4’s powerful 3D editor



Enable commanders to plan missions and issue orders to AI

Allow administrators to change any aspect of the scenario

Give trainees control of an avatar from first-person perspective

Provide full-featured radio simulation for communication practice



Replay scenarios in 2D and 3D from any perspective, anywhere on the virtual Earth

Review performance measures that are saved automatically during AAR capture

Through open APIs, leverage AAR data for use in third-party training management tools



Execute scenarios anywhere in the world within VBS4’s high-fidelity, procedurally enhanced whole-world database out of the box. Customize the existing whole-Earth base terrain in VBS4 with the new and intuitive VBS Geo mode or generate new high-fidelity insets rapidly without the need for terrain experts.



Not an engineer? No problem. You can build missions 10-30x faster & edit terrains 10x faster in VBS4. By greatly increasing the speed that training content can be generated, VBS4 frees up instructor time to concentrate on the learning points of an exercise, leading to more effective training.



Unlike many other game engine-based simulations, the VBS4 engine (VBS Blue) was developed specifically to serve the military simulation and training domain. VBS Blue offers millimeter accuracy and global scale simultaneously, and it has a flexible terrain ingestion pipeline capable of facilitating quick use of terrain data from any conceivable source.

The engine can render the Earth from a height of a few centimeters up to tens of thousands kilometers with a smooth transition.
The VBS4 Engine is capable of ingesting any conceivable type of geo-referenced data (including satellite and drone-captured imagery).
The engine supports 1000s of military-focused individual features ranging from realistic first-person simulation to unmanned system simulation to electronic warfare.
Efficiently render complex scenes in a performant manner with the engine optimized to handle 1000s of AI entities, densely vegetated areas, and complex urban areas.
The engine can render the Earth from a height of a few centimeters up to tens of thousands kilometers with a smooth transition.
Customizable weather in the engine supports 4 different precipitation types and 4 temperate and subpolar seasons.
Waves are simulated with 4 cm precision in the VBS4 engine seasons.
