## What project CR4 buys

One World Terrain (OWT) supports the current National Security Strategy (NSS), National Defense Strategy, and National Military Strategy (NMS) as one of the Army's modernization efforts, and one of three core functions of the Synthetic Training Environment - Software (STE-SW). OWT provides a 3D global terrain capability and associated information services that support virtual replication of the physical Earth to reflect the complexities of the operational environment in support of Multi-Domain Operations (MDO) for use in training. OWT enables leaders, Soldiers, and units to train in simulated complex operational environments across the globe replicating dense urban, woodland, jungle, desert, and subterranean areas before the first fight begins. OWT modernizes the Army's terrain generation capability by automatically processing raw geospatial data into a format that is editable and consumable by standard commercial tools and technologies. It provides the tools to incorporate approved geospatial information updates and local terrain surveys into the OWT foundational repository and will be used by the Synthetic Training Environment (STE) to represent terrain in a virtual environment. In FY 2021, OWT entered the Software Acquisition Pathway. As part of the STE family of programs, OWT provides rapid and iterative delivery of its capabilities to the Training Support System/Training Management Tool (TSS/TMT) for integration into the STE-SW that supports the Reconfigurable Virtual Collective Trainer (RVCT), Next Generation Constructive (NGC), and future STE training systems. FY 2027 OWT RDT&E funds will continue the development of capabilities that automatically process geospatial data into simulation ready 3D terrain for training use; provide geospatial data and models that are editable by standard commercial tools and technologies; and incorporate approved geospatial data updates and user? generated terrain captures into the OWT repository. FY 2027 RDTE funds will also address the OWT requirements codified in the STE-SW ICD, validated 1QFY2025, for One World Terrain (OWT) to accommodate the increased ingestion of terrain, common models, interoperability standards for the acceleration of the Minimum Viable Product (MVP) core capability requirements to conduct Joint and Multi-Domain Operations (MDO), the ability to model MDO, and Core Services.

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

## Named R-3 performers

> 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 OWT

FY 2027 funding will support program management costs and updated terrain data for Mapping and Cartographic Information Systems (MCIS) and map correlation to reflect pre-exercise ground conditions. In addition, OWT will continue to refine constructive terrain data bases that cover the entire globe in support of Multi Domain Operations…
