**R-2A activity** of project DS7 — High Performance Computing Modernization Program  
**Program element:** 0603461A — High Performance Computing Modernization Program  
**Component:** U.S. Army · **Budget Activity:** 3  
**Vintage:** President's Budget PB2027

## Summary

This activity requests $125.0M in FY2027, 58% of project DS7, down 5.7% 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.** Will continue to provide direct support to 100's of DoW research, development, test, and evaluation projects by assessing and integrating advanced technologies in high-performance computing systems. Will enable DoW projects access to 26, or more, high-performance computers across a full range of classifications at five geographically distributed DoW supercomputing resource centers collectively providing over 150 quadrillion floating-point operations/calculations per second of compute capability. Will continue to conduct physics-driven, interdisciplinary, large-scale scientific and engineering simulations and analyses that mature and demonstrate capabilities for important DoW research, development, and test priorities. Will integrate advanced technologies for data-intensive computing, persistent data services, and data archiving/retrieval for artificial intelligence/machine learning and other DoW use cases employing large volumes of data (over 350 quadrillion bytes in total). Will transition technologies for accelerating computations and sharing of highly classified high-end computers among multiple special programs. Will mature technologies for seamless access to resources across DoW Supercomputing Resource Centers and transparent interfaces with cloud computing services for those DoW projects that demand a hybrid compute capability. Will mature and transition advanced technologies to enable supercomputing capabilities to support technology transition efforts in acquisition engineering and international collaboration while protecting sensitive data and information.

**FY2026 to FY2027 change.** Funding decrease reduces support for high-end computational capabilities at DoW Supercomputing Resource Centers with decreased focus on advancing artificial intelligence capability and enabling cloud computing.

## Before the request year

**FY2026 plans — current year.** Provides direct support to 100's of DoW research, development, test, and evaluation projects by assessing and integrating advanced technologies in high-performance computing systems. Enables DoW projects access to 24 or more high-performance computers across a full range of classifications at five geographically distributed DoW supercomputing resource centers collectively providing over 125 quadrillion floating-point operations/calculations per second of compute capability. Continue to conduct physics-driven, interdisciplinary, large-scale scientific and engineering simulations and analyses that mature and demonstrate capabilities for important DoW research, development, and test priorities. Continues to mature and transition emerging technologies for data-intensive computing, persistent data services, and data archiving/retrieval for artificial intelligence/machine learning and other DoW use cases employing large volumes of data (over 300 quadrillion bytes in total). Continues to research and mature new technologies for accelerating computations and sharing of highly classified high-end computers among multiple special programs. Continues to research and demonstrate seamless access to resources across DoW Supercomputing Resource Centers and transparent interfaces with cloud computing services for those DoW projects that demand a hybrid compute capability. Continue to assess and develop new technologies that enable supercomputing capabilities to support technology transition efforts in acquisition engineering and international collaboration while protecting sensitive data and information.

**FY2025 accomplishments.** Matured and demonstrated 24 or more high-end computers across a full range of classifications at five geographically distributed DoD supercomputing resource centers to collectively provide over 120 quadrillion floating-point operations/calculations per second of capability. Continue to conduct complex, highly-coupled, large-scale, scientific and engineering simulations and analyses that mature and demonstrate capabilities for important DoD research, development, and test priorities. Continue to mature and demonstrate data-intensive computing, persistent data services, and data archiving/retrieval for artificial intelligence/machine learning and other DoD use cases employing large volumes of data (over 250 quadrillion bytes in total). Continue to mature new technologies for accelerating computations and sharing of highly classified high-end computers among multiple special programs. Continue to mature and demonstrate seamless access to resources across DSRCs and transparent interfaces with cloud computing services for those DoD entities that demand a hybrid compute capability. Implemented new high-end computing capabilities to support technology transition efforts in acquisition engineering and international collaboration.
