BAE Systems Onearc Usa, Inc.

BAE Systems Onearc Usa, Inc., doing business as Bohemia Interactive Simulations Inc. (BISim), is a subsidiary of BAE Systems Technology Solutions & Services Inc. that develops and licenses virtual simulation training software to the Department of Defense and federal training agencies as a prime contractor, competing full-and-open without set-aside designations. The company is headquartered in Orlando, Florida, and operates as a for-profit manufacturer and software publisher focused on high-fidelity multi-domain training environments, primarily under NAICS 511210 (Software Publishers) and NAICS 541511 (Custom Computer Programming Services).

BISim's federal portfolio centers on its Virtual Battlespace (VBS) product suite—VBS3 and VBS4 simulation software, hardware kits, technical support, training delivery, and Games for Training development. Recent representative prime work includes a $25.8 million definitive contract from PEO Simulation, Training and Instrumentation (awarded June 2022, completion June 2027) for Games for Training development and delivery; a $48.1 million single-award IDIQ from Army Security Assistance Command (awarded September 2025, completion September 2032) for Foreign Military Sales VBS software suites, hardware, professional services, training, and support renewals, with two delivery orders already issued to Romania ($3.9 million, completion August 2026) and Morocco ($1.5 million, completion July 2026); and a $469.5 million definitive contract with PEO Simulation, Training and Instrumentation (awarded October 2025, completion October 2028) for VBS4 and Terra Tools licenses and software support for the Georgia Joint Training and Evaluation Center. BISim also holds a $144.3 million multiple-award Other Transaction IDV with Marine Corps (awarded December 2025) for Command PE licenses, training, and project support services.

Customer concentration tracks heavily to Army and Marine Corps training and Foreign Military Sales channels. The top five funding agencies account for 93% of combined potential value across recent awards: Army Security Assistance Command (8 awards, $57 million—primarily Foreign Military Sales VBS cases for Nigeria, Kenya, Iraq, Ukraine, Tunisia, and others); Army PEO Simulation, Training and Instrumentation (5 awards, $47.1 million); Marine Corps (16 awards, $35.1 million); Naval Air Systems Command and Naval Air Warfare Center combined (4 awards, $907 thousand); and Army Forces Command (1 award, $500 thousand). The Marine Corps leads by award count despite dollar concentration sitting with Army FMS and PEO-ST&I channels.

BISim places task orders against two named IDIQ vehicles: Indefinite Delivery Contract M6785415D7800 (10 task orders, $12.4 million combined potential value) and Indefinite Delivery Contract W900KK25DA001 (2 task orders, $5.4 million combined potential value). Additional leverage comes through ASTRO, Information Analysis Center Multiple-Award Contract, and One Acquisition Solution for Integrated Services vehicles.

Activity has grown sharply year over year—one award in 2024 to twelve in 2025, with six awards (combined potential value $31.4 million) reaching ultimate completion within the next twenty-four months, creating recompete exposure on VBS4 support and seat-license renewals across Army, Marine Corps, and Air Force organizations. BISim operates as a subcontractor to Booz Allen Hamilton on modernization analysis and strategic planning work (Defense Intelligence Analysis and III Marine Expeditionary Force Stand-In Force planning, awarded 2023–2025), to Science Applications International Corporation on modeling and simulation development (HWIL M&S engineering, awarded December 2023), and to KBR Wyle Services on Naval Air Systems Command training systems analysis (awarded December 2025). The company's sub engagement represents only 8% of its recent award footprint by count; the vendor operates predominantly as a prime.
