What Bohemia Interactive Simulations (BISim) does

Bohemia Interactive Simulations (BISim), now operating commercially as BAE Systems OneArc, is a global software company specializing in military synthetic training and simulation. Founded in 2001 and headquartered in Prague with US operations based in Orlando, BISim builds the Virtual Battlespace (VBS) platform family, with VBS4 as its current flagship and VBS5 released in February 2026. The platform is used by the U.S. Army, U.S. Marine Corps, and more than 60 nations for collective tactical training, mission rehearsal, and debriefing across air, land, maritime, space, and cyber domains. The product portfolio is organized into four categories: Simulation (VBS4, VBS Builder Edition), Geospatial (Mantle, Mantle Enterprise, TerraTools), Visualization (Blue IG, Blue IG SDK), and Interoperability (Pitch Infrastructure, Pitch Talk, Pitch Debrief, Pitch Developer Tools), complemented by integrated solutions such as BattleLab, FlowState (drone operations training), and SceneCast.

BISim's core technology is built on NATO interoperability standards, including HLA (High Level Architecture) and the emerging IEEE 1516-2025 (HLA 4) baseline, enabling distributed simulation across allied forces. TerraTools and Mantle handle terrain generation and correlation; Blue IG delivers realistic high-performance visuals; and Pitch products provide the distributed simulation backbone. The installed base spans 300+ system integrators globally, embedding BISim products into larger defense training systems delivered by integrators such as Rheinmetall (German Army Puma IFV AGSP) and Indra (Spanish Army land vehicle simulators).

BISim was acquired by BAE Systems in 2022 for approximately $200 million and now operates as a wholly-owned subsidiary. Revenue is generated primarily through multi-year enterprise license contracts with defense ministries (e.g., a 5-year Canadian DND Digital Virtual Trainer contract with three option years, and a £7.2 million UK MOD DVS2 contract) bundled with maintenance and support, supplemented by one-time licenses and custom development work for specific customer requirements. Pricing is quote-based and awarded via competitive defense procurement. In December 2025, BAE Systems consolidated BISim with TerraSim and Pitch Technologies under the unified OneArc brand to deliver synthetic training, geospatial, data analytics, and AI solutions to US, NATO, and allied militaries.

Revenue model

1. Enterprise License Contracts: BISim generates revenue primarily through multi-year enterprise license contracts with defense forces, such as the five-year contract with the Canadian Department of National Defence for the Digital Virtual Trainer (DVT), with additional option years for maintenance support. These contracts bundle software licenses (VBS4, Blue IG, TerraTools) with maintenance and support services.
2. Software Licensing and Custom Development: Revenue is generated from licensing VBS, Blue IG, Mantle, TerraTools, and Pitch product families to defense integrators and end-user militaries. Customized simulation development and supplementary development work for specific customer requirements (e.g., NZDF customized simulation) also contributes revenue.
3. Support and Maintenance Services: Post-contract maintenance and support services, including customer support portals for specific programs (UK MOD DVS2, CA DND DVT, USMC), contributing recurring maintenance revenue streams.

Core offering

BISim develops and licenses a portfolio of synthetic training environment software for military forces, anchored by the VBS4/VBS5 virtual battlespace platform used for scenario creation, mission rehearsal, and after-action review. The offering is extended by Blue IG image generation, TerraTools and Mantle terrain tools, and Pitch distributed-simulation interoperability products that together deliver end-to-end LVC (live, virtual, constructive) training for defense customers worldwide.

Product overview

OneArc (formerly Bohemia Interactive Simulations) offers a comprehensive portfolio of military simulation software products organized into four main categories: Simulation (VBS4, VBS Builder Edition), Geospatial (Mantle, Mantle Enterprise, TerraTools), Visualization (Blue IG, Blue IG SDK), and Interoperability (Pitch Infrastructure, Pitch Talk, Pitch Debrief, Pitch Developer Tools). The core platform is VBS4, a virtual desktop training environment used by the U.S. Army, Marine Corps, and over 60 nations, which provides virtual battlespace creation, terrain building, mission planning, and debriefing capabilities. Blue IG serves as the image generator delivering realistic visuals, while TerraTools and Mantle provide terrain generation and correlation. Pitch products enable distributed simulation interoperability based on open international standards. These products are complemented by integrated solutions including BattleLab (training classroom), FlowState (drone operations training), and SceneCast (geospatial asset integration). The portfolio enables full-spectrum synthetic environments for training, testing, planning, and decision-making across U.S., NATO, and allied military forces.
