Description
Description — Synthetic Training Environment (STE)
These funding lines are directly aligned to the Army Modernization Priorities. STE continues to support the SECARMY and CSA's guidance on the Army's continuous transformation to become more lethal in the live, virtual and constructive training environments enabling Commanders to prioritize time and resources towards building lethality and cohesive teams. STE continues to develop and deliver capabilities that enable Soldiers to shoot, move, communicate, and be experts in their craft through tough, realistic squad to brigade level individual/collective training tasks. The Synthetic Training Environment (STE) is the next generation holistic collective training capability that will enable leaders, Soldiers, and units to train where they will fight, with the partners they will fight with, and in complex operational environments to include dense urban, woodland, jungle, dessert, and sub-terrain, before the first fight begins. STE will revolutionize Army training by providing the repetition necessary at the Point of Need for improved proficiency prior to live training or operations - improving Soldier lethality and survivability. The STE program has multiple OTAs awarded in support of prototyping capabilities and will implement multiple adaptive acquisition framework pathways including 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, shipboard, deployed). 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 Soldier Lethality's IVAS program); 4) STE Live; and 5) Soldier Virtual Trainer. STE-SW is comprised of Synthetic Training Environment training capability consisting of One World Terrain (OWT), Training Simulation Software (TSS), Training Management Tools (TMT), and Next Generation Constructive (NGC). NGC will be scaled up from what the vendor is able to deliver through the STE-SW platform. NGC, as part of STE-SW, will provide constructive training capability to Corps and Army Service Component Commands (ASCC) to train commanders and their staffs. 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 Integrated Visual Augmentation System (IVAS) for the close combat Squads that enables IVAS to be a fight, rehearse, and training platform. STE Live focuses on the 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. STE-Live enables real Soldiers to train on "bloodless battles" against human opposing forces with all the capabilities of Brigade Combat Team with higher realism than ever before. Currently, 40% of the weapons and capabilities cannot be replicated in live force-on-force training. SVT will provide training to Soldiers Army wide by providing Weapons Skills Development (WSD) and Joint Fires Trainer (JFT). Notes: The fluctuations in overall unit costs on the P-40 are dependent on the mix of items being procured in the sub-projects. Details on specific unit costs will be found on the individual P5's. STE-Software (STE-SW) was previously referred to as STE-lnformation System (STE-IS). STE is part of Army Transformation Initiative.
