# Engineering, Support, Test & Evaluation for OWT

**R-2A activity** of project CR4 — STE One World Terrain (OWT)  
**Program element:** 0604121A — Synthetic Training Environment Refinement & Prototyping  
**Component:** U.S. Army · **Budget Activity:** 4  
**Vintage:** President's Budget PB2027

## Summary

This activity requests $23.4M in FY2027, 100% of project CR4, down 9.3% on FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** 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. Additionally, OWT will support Warfighter Exercise 27-01, the first NGC Corps level exercise directed by the Army. Also, base funding will continue efforts to improve OWT 3D terrain data integration into the Synthetic Training Environment (STE) Family of Programs and Terrain Services in support of NGC development in accordance with validated STE? SW ICD 1QFY2025. Terrain Services are the set of common capabilities provided by OWT including the ingestion and scaling of authoritative data sources, common models, select joint data and interoperability standards, and system architecture.

**FY2026 to FY2027 change.** FY 2027 RDTE funding decrease is due to the transition from purchasing licenses to a subscription based terrain data service. Subscription services offer the advantage of lower costs, continuous updates, and greater terrain customization. The subscription service grants access to all available terrain data that has already been collected by the vendor.

## Before the request year

**FY2026 plans — current year.** Funding will support the continued automation of OWT feature extraction and attribution as well as program management costs. OWT will provide updated terrain data to Mapping and Cartographic Information Systems (MCIS) for map correlation to reflect pre-exercise ground conditions. In addition, OWT will begin to develop 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. Also, base funding will continue efforts to improve OWT 3D terrain data integration into the Synthetic Training Environment (STE) family of programs and Terrain Services in support of NGC development in accordance with validated STE-SW ICD 1QFY2025. Terrain Services include ingestion and scaling of authoritative data sources, common models, select joint data and interoperability standards, and system architecture. Funding will establish enterprise level business processes and services enabling OWT to efficiently develop, operate, and secure capabilities in accordance with OSW Digital Engineering and Army Digital Transformations Strategies. Efforts will promote synergies between the training and testing enablers to improve product development, integration, and cyber activities, and to promote re-use of common assets and services to Army modernization priorities.

**FY2025 accomplishments.** Funding will support the continued automation of OWT feature extraction and attribution as well as program management costs. In addition, OWT will begin to develop 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. Also, base funding will continue efforts to improve OWT 3D terrain data integration into the Synthetic Training Environment (STE) family of programs.
