## What project CR3 buys

The Synthetic Training Environment (STE) Live program develops live training systems in concert with the STE Abbreviated Capabilities Development Document (A-CDD). The STE Live program converges live training with the STE, providing units the necessary training components to accelerate and sustain combined arms maneuver proficiency in support of Multi-Domain Operations (MDO). The STE Live program focuses on the development of a next generation live training architecture that leverages innovative technologies and standards to enable the realistic exercise of unit combat weapons up to brigade level in Multi Domain Operation Environments. The challenge today is the Army cannot train as it fights since 40% of Brigade Combat Team (BCT) platforms weapons effects are currently not simulated by today's live training system, Multiple Integrated Laser Engagement System (MILES). STE Live next generation systems will replicate the following new engagement types, improve sensory feedback, increase realism of direct fire engagement, increase realism of battle damage assessments, improve after action reviews and improve instrumentation at the Combat Training Centers and Home Stations: Indirect Fire, Counter-Defilade (M320, MK-19), Place Object (Mines), Thrown Objects (Grenades), Dropped Objects (Bombs), Guided Weapon (Missiles), Autonomous Weapon (Missiles, Smart Munitions), Direct Energy (laser), Radiant Energy (Sonic, Microwave), Chemical, Biological, Radiological, Nuclear, and Explosives (CBRNE) Plumes and Cyber. FY 2027 RDTE funds will continue to revolutionize Soldier Simulation and Training systems to include a Synthetic Training Environment focused on the Rifle Platoon Training System. Additionally, FY 2027 funding will advance the Combat Vehicle Training System products. The total cost of the STE-LTS MTA Rapid Prototyping (RP) effort is $232.0 million RDT&E from FY 2022 to FY 2026.

**R-3 lines of work:** Product Development; Support; Test and Evaluation.

## Activities (R-2A) — 1

| Activity | FY2025 | FY2026 | FY2027 | Move | Page |
|---|---|---|---|---|---|
| Engineering, Support, Test & Evaluation for STE Live | 32.9 | 14.5 | 29.2 | +101% | [a0](https://hitchintel.com/programs/0604121A/CR3/a0) |

> Activities carry the prior, current and budget year only — no five-year plan. In the request year they partition this project exactly; in earlier years they can under-cover it.

### Engineering, Support, Test & Evaluation for STE Live

FY 2027 funds in the amount of $29.175 million will continue development for direct fire, automated casualty, shoulder launched munitions, indirect fire, counter defilade, and network products. FY 2027 funds will also continue the combat vehicle, sUAS, C-sUAS development.
