Synthetic Training Environment Refinement & Prototyping
Abstract
These funding lines are directly aligned to the Army Synthetic Training Environment (STE) Modernization Priority. The Synthetic Training Environment (STE) is the next generation holistic combined arms collective training capability that will enable leaders, Soldiers, and units from Squad through Army Service Component Command to train where they will fight, with the partners they will fight with, and in complex operational environments in support of Multi-Domain Operations (MDO). STE will revolutionize Army training by providing the repetition necessary at the Point of Need (PoN) for improved proficiency prior to live training or operations- improving Soldier lethality and survivability. The STE program has multiple Other Transaction Authority (OTA) contracts awarded, and will implement an incremental fielding approach leveraging the Software Acquisition pathway (SWP) and the Middle Tier of Acquisition (MTA) pathway. The STE will be available where training occurs (home station, combat training centers, armories, institutions, and deployed locations). The STE is comprised of five main signature efforts: 1) STE-Software (STE-SW); 2) Reconfigurable Virtual Collective Trainers (RVCT); 3) Squad Immersive Virtual Trainer (SiVT, in partnership with Solider Lethality's Integrated Visual Augmentation System (IVAS) program); 4) STE Live; and 5) Solider Virtual Trainer. STE-SW is comprised of Synthetic Training Environment training capability consisting of One World Terrain (OWT), Training Simulation Software (TSS), and Training Management Tools (TMT). The RVCT will allow units to collectively train, using proponent developed Combined Arms Training Strategies (CATS), on a simulated, fully interactive, real-time battlefield. Squad Immersive Virtual Trainer (SiVT) is the immersive training capability delivered as part of the IVAS for the close combat Squads that enables IVAS to be a fight, rehearse, and training platform. STE Live focuses on the development of twelve engagement types and five instrumentation enablers. The twelve engagement types are direct fire, counter-defilade fire, indirect fire, dropped objects, placed objects, thrown objects, guided weapons, autonomous weapons, cyber, directed energy, radiant energy, and plume; the five instrumentation enablers are calculations, networks, sensors, terrains, and transmitters. SVT will provide training to Soldiers Army wide by providing a Weapons Skills Development (WSD), Joint Fires Trainer (JFT) and Use of Force (UoF). A future STE line of effort includes Next Generation Constructive (NGC) that will be scaled up from what the vendor is able to deliver through the STE-SW platform. NGC, as part of STE-Software, will provide constructive training capability to echelons above brigade. FY2025 Projects CR2 through CR7 Base RDTE dollars in the amount of $136.029 million funds significant development efforts in the STE-Software (STE-SW) which include Training Simulation Software/Training Management Tool (TSS/TMT) and One World Terrain (OWT), Reconfigurable Virtual Collective Trainer (RVCT), Squad Immersive Virtual Trainer (SiVT), Soldier Virtual Trainer (SVT), and STE Live. The total cost of the STE Live (CR3) Middle Tier of Acquisition (MTA) effort is $360.9 million RDTE from FY2022 to FY2026. The total cost of the STE RVCT (CR5) MTA effort is $119.1 million RDT&E from FY 2020 to FY 2024. The remainder of STE RVCT is fully funded across the Future Years Defense Program The total cost of the SVT (CR7) Middle Tier of Acquisition effort is $108.8 million from FY2022 to FY2027, including RDT&E ($101.6M) and Procurement ($7.2M) of prototype units.

- Change Summary Explanation
- Increase of $2.464 million supports Project CR2, TSS/TMT, to continue with the DevSecOps approach, refinement of Brigade level training capability, and development of the Intel, Sustainment, Cyber, and Protection Warfighting Functions. Increase also reflects Program Management support cost that was realigned from OMA to RDTE. Increase of $.696 million supports Project CR3, STE Live, development activities for Increment 3 for autonomous weapon, directed energy and radiant energy efforts. Increase of $5.323 million supports Project CR4, One World Terrain, to continue development efforts to provide advanced capabilities that allow user-generated terrain captures to be incorporated into the OWT repository and standard commercial tools and technologies to be used for geospatial data editing. Increase also reflects Program Management support cost that was realigned from OMA to RDTE. Increase of $7.434 million in Project CR5, STE Reconfigurable Virtual Trainer (RVCT), is to continue development on RVCT future variant kits and complete integration lab assets. Increase of $18.889 million supports Project CR6, Squad Immersive Virtual Trainer (SiVT), to continue technology insertion into the SiVT system, including technologies that improve outdoor capability, increase the reliability and connectivity of the systems. Increase of $13.539 million supports Project CR7, STE Soldier Virtual Trainer (SVT), development of Phase 3 Weapon Skills Development Increment 2, Joint Fires Training, and Use of Force capabilities.
