## Summary

This activity requests $347.8M in FY2027, 64% of project 657011, up 35% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** The program will continue to design, develop, integrate and test the LRSO weapon system through the EMD contract. During FY2027, the program plans to complete Developmental Test and Evaluation program execution on B-52. Related FY2027 Activities include, but are not limited to, the following: - continue reliability growth, manufacturability, and maintainability maturation actions for formal Developmental Test and Evaluation activities. - continue systems engineering activities focusing on design for reliability and design for manufacturing. - continue test activities, such as, but not limited to, continued envelope testing and weapon system flight tests. - continue planning for Production Readiness Reviews prior to the build of the IOT&E units. - continue qualification and nuclear hardness testing to verify the system operates in intended environments. - continue planning and development of the logistics support systems. - develop and build associated carriage and launcher equipment, trainers, test equipment and support equipment. - continue to plan, develop, and mature support systems to include Common Support Equipment/Peculiar Support Equipment and transportation equipment. - continue planning for the use of Model Based System Engineering tools during Operations and Sustainment phase in order to transform supply chain management. - continue to mature the weapon system by conducting trade studies, system engineering, test activities, and system modeling and simulation. - continue to further develop analytical, information technology, and data management capabilities. - continue to implement information systems and information technology design to support Engineering and Manufacturing Development (EMD) execution. - continue to expand and mature the analytical, information technology, test, and data management capabilities to ensure access to weapon system design information is properly controlled and securely transmitted between the Government and contractors. - continue to modify, modernize, and expand the analytic environment and labs to support EMD activities to enable full execution of the program's capability to own the technical baseline throughout the program life cycle. This involves establishing a digital engineering system including a supporting environment/infrastructure to perform digital activities, collaborate with and communicate across stakeholders. - continue to plan and execute critical software risk reduction activities. - continue to plan and execute payload and aircraft integration efforts. - continue to, through best program practices, ensure the following are met; requirements flow down, requirement allocation to hardware and software, and the requirements compliance matrix.

**FY2026 to FY2027 change.** Funding increased due to completion of EMD/DT activities and support activities leading up to Aircraft Monitor & Control (AMAC) in FY 2027

## Before the request year

**FY2026 plans — current year.** The program will continue to design, develop, integrate and test the LRSO weapon system through the EMD contract. During FY2026, the program plans to continue Developmental Test and Evaluation program execution on B-52. Related FY2026 Activities include, but are not limited to, the following: - continue reliability growth, manufacturability, and maintainability maturation actions for formal Developmental Test and Evaluation activities. - continue systems engineering activities focusing on design for reliability and design for manufacturing. - continue test activities, such as, but not limited to, continued envelope testing and weapon system flight tests. - continue planning for Production Readiness Reviews prior to the build of the Initial Operational Test & Evaluation (IOT&E) units. - continue qualification and nuclear hardness testing to verify the system operates in intended environments. - continue planning and development of the logistics support systems. - develop and build associated carriage and launcher equipment, trainers, test equipment and support equipment. - continue to plan, develop, and mature support systems to include Common Support Equipment/Peculiar Support Equipment and transportation equipment. - continue planning for the use of Model Based System Engineering tools during Operations and Sustainment phase in order to transform supply chain management. - continue to mature the weapon system by conducting trade studies, system engineering, test activities, and system modeling and simulation. - continue to further develop analytical, information technology, and data management capabilities. - continue to implement information systems and information technology design to support Engineering and Manufacturing Development (EMD) execution. - continue to expand and mature the analytical, information technology, test, and data management capabilities to ensure access to weapon system design information is properly controlled and securely transmitted between the Government and contractors. - continue to modify, modernize, and expand the analytic environment and labs to support EMD activities to enable full execution of the program's capability to own the technical baseline throughout the program life cycle.
