What the FY2027 request buys

Verbatim from the R-2A exhibit for project 655238 of PE 0605238F. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.

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.

Before the request year

FY2026: the year under way

Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.

FY2026 plans — current year

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. 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. Expand and update information systems, IT infrastructure, and cybersecurity networks to support highly classified activities and maintain connectivity with mission partners. Enhance the DevSecOps environment and data transport capabilities across classified networks using cross-domain solutions. Prioritize cloud network infrastructure improvements to increase reliability, availability, and security. 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.

Three years, and no five-year plan

An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.

This activity is 9.6% of project 655238's FY2027 request and 9.6% of PE 0605238F's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
