**R-2A activity** of project RD — NUCLEAR TECHNOLOGIES AND CAPABILITIES DEVELOPMENT  
**Program element:** 0605000BR — Counter Weapons OF MASS Destruction Systems Development  
**Component:** Defense-Wide · **Budget Activity:** 5  
**Vintage:** President's Budget PB2027

## Summary

This activity requests $16.7M in FY2027, 100% of project RD, up 13% 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.** - Improve autoscaling and load balancing to ensure Nuclear, Chemical, Biological, Radiological and high-Explosive Analysis Toolset optimized for increased speed, with no impact to fidelity, due to large data input and flow. - Develop multi-mission monitoring capabilities to improve U.S. International Monitoring System (IMS), strategic DoW missions, and Interagency emergency response. - Provide U.S. Strategic Command higher fidelity targeting analytic capabilities, expanding to meet the UK Ministry of Defense and North Atlantic Treaty Organization (NATO)/Supreme Headquarters Allied Powers Europe needs through Enhanced Consequence Analysis. - Begin integration testing of transformative noble gas analysis system for implementation in the Nuclear Arms Control Technologies IMS. - Begin assessments of commercial signature collection and analysis technologies and methodologies for potential integration into IMS. - Develop additional Nuclear Capabilities Services tools to provide common core nuclear effects calculation engine for all DTRA programs, updated semi-annually, expanding to support Enhanced Consequence Analysis and to close gaps identified in the Department of War Operating in a Nuclear Environment Capabilities Based Assessment.

**FY2026 to FY2027 change.** The change from FY 2026 to FY 2027 aligns priority spending with the Secretary of War’s highest priorities to strengthen readiness, modernize capabilities, and sustain the force. This includes an increase to expand support for Enhanced Consequence Analysis and close gaps identified in the Department of War Operating in a Nuclear Environment Capabilities (ONE) Based Assessment.

## Before the request year

**FY2026 plans — current year.** - Develop multi-mission monitoring capabilities through the Nuclear Arms Control Technologies effort to improve U.S. IMS, strategic DoW missions, and Interagency emergency response while strengthening arms control and preparing for WMD crisis events. - Transition installation of 32nd U.S. IMS station into operations, enabling DoW’s nuclear explosion monitoring capacities and detection of evasive nuclear tests. - Start testing and evaluation of next-gen radionuclide particulate sampler for potential IMS integration to improve detection capability. - Begin integration testing of transformative noble gas analysis system in preparation for transition to DoW to improve nuclear detonation attribution. - Provide U.S. Strategic Command (USSTRATCOM) higher fidelity targeting analytic capabilities via Enhanced Consequence Analysis, expanding to meet the UK Ministry of Defense, and North Atlantic Treaty Organization (NATO)/Supreme Headquarters Allied Powers Europe needs.

**FY2025 accomplishments.** - Integrate impacts to infrastructure capabilities into cloud-ready nuclear planning tools for U.S. Strategic Command (USSTRATCOM), UK/Ministry of Defense, and North Atlantic Treaty Organization (NATO)/ Supreme Headquarters Allied Powers Europe (SHAPE). - Implement algorithms to enable transition of infrasound propagation models to DoD systems and complete Operational Test and Evaluation of next generation International Monitoring System (IMS) radionuclide lab analysis capability. - Complete installation of 32nd IMS station and deliver improved "state of health" IMS performance and predictive algorithms for monitoring arrays using artificial intelligence/machine learning techniques. - Demonstrate emerging-threat monitoring capability that leverages current systems and extend comprehensive analyses of sensor data from DTRA/Department of State/National Nuclear Security Administration (high-explosive experiments by leveraging machine learning techniques.
