## Summary

This activity requests $433.6M in FY2027, 9.6% of project 655238, up 21% 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.** Continue to ensure the program has the necessary manpower, technical expertise, management, physical security, IT infrastructure, and cybersecurity capabilities to successfully develop and acquire the weapon system. Continue to manage and acquire support from various program partners such as Federally Funded Research and Development Centers (FFRDCs), University Affiliated Research Centers (UARCs), corporations (to include the prime contractor) and other government activities to ensure the program has the correct mix of skills required to develop the weapon system and own the technical baseline. Continue to expand and update information systems, IT infrastructure, and cybersecurity networks to support highly classified activities and maintain connectivity with mission partners. Continue to enhance the DevSecOps environment and data transport capabilities across classified networks using cross-domain solutions. Continue to prioritize cloud network infrastructure improvements to increase reliability, availability, and security. Continue to build and establish a digital industrial base for innovation around the Sentinel enterprise to maintain digital modularity and adaptability for the life cycle of the weapon system as well as to continue the digital transformation to support the Sentinel program.

**FY2026 to FY2027 change.** Funding increased due to the government portion of the program restructure activities and TMRR efforts to achieve MS-B while the program office continues portions of the original program.
