Synthetic Training Environment Refinement & Prototyping

The Synthetic Training Environment Refinement & Prototyping program (PE 0604121A) is a major Army modernization initiative focused on developing, refining, and prototyping advanced training systems to support multi-domain operations (MDO) and improve soldier readiness. The overarching goal is to provide a holistic, integrated training environment that enables soldiers and units to train as they fight, across live, virtual, and constructive domains. The program supports the Army's transformation priorities by delivering realistic, scalable, and rapidly upgradable training capabilities, leveraging modern software acquisition pathways and modular open system architectures.

STE Information Systems (TSS, TMT) is the core software element of the Synthetic Training Environment, providing the foundational simulation engine and management tools. The objectives include converging live, virtual, gaming, and constructive training environments into a unified platform, enabling simultaneous and distributed training from the squad to the Army Service Component Command (ASCC) level. Efforts focus on accelerating the Next Generation Constructive capability, supporting large-scale combat operations and multi-domain training, integrating cloud-based solutions, and developing semi-autonomous opposing forces for realistic scenario generation. The program emphasizes agile software development, continuous integration, and persistent user feedback to ensure operational relevance.

STE Live is dedicated to modernizing live training systems by developing next-generation architectures and instrumentation that replicate a broad range of engagement types, including direct and indirect fire, cyber, and directed energy. The program aims to address current limitations in live training, such as the inability to simulate many weapon effects, by introducing new sensory feedback, improved battle damage assessment, and enhanced after-action review capabilities. Activities include prototyping and testing advanced training systems for shoulder-launched munitions, ground combat vehicles, and network integration at Combat Training Centers, with the goal of achieving production-ready solutions within a short timeline.

STE One World Terrain (OWT) provides a global, high-fidelity 3D terrain database and associated tools to support virtual training and mission rehearsal. OWT's objectives are to automate the processing of geospatial data into simulation-ready formats, enable user-generated terrain updates, and ensure seamless integration with other STE components. Funding supports expanding terrain datasets, improving data integration with mapping and cartographic systems, and developing enterprise-level services to support joint and multinational operations. OWT is critical for enabling realistic, geographically accurate training scenarios at all echelons.

STE Reconfigurable Virtual Trainer (RVCT) delivers adaptable, transportable virtual training systems for collective maneuver, gunnery, and mission rehearsal training. The RVCT encompasses both aviation and ground platforms and is designed to be software-agnostic, supporting rapid updates and integration with the STE software baseline. Objectives include developing new variant kits, enhancing cybersecurity, and completing integration lab asset procurement. The RVCT program supports rapid prototyping and fielding to address capability gaps in legacy training systems and to provide high-fidelity simulation for modern operational environments.

STE Soldier Virtual Trainer (SVT) focuses on individual and crew-level immersive training, integrating Weapon Skills Development, Joint Fires Training, and Use of Force modules. SVT aims to replace legacy systems with a modular, person-transportable solution that supports both individual and collective tasks. Efforts are centered on developing prototype designs for core integration and advanced training capabilities, informed by user feedback and operational demonstrations. The acquisition strategy employs phased development, agile processes, and continuous integration to ensure timely delivery and adaptability.
