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.
Continue to mature Sentinel specifications, architecture, and design through rigorous systems engineering to include modular architectures, external interface management, modeling and simulation, and testing to ensure the appropriate level of maturity required for each technical review. Continue to collaborate with mission partners to enhance capabilities, maintain technical expertise, and ensure seamless integration of critical assets. Continue to improve certification processes, develop a common cryptographic device, and advance model-based systems engineering for efficient sustainment. Continue to align system requirements and architectural documentation. Execute systems security engineering activities: Systems Theoretic Process Analysis (STPA), supply-chain risk management, program protection planning and execution, and multi-disciplinary adversarial emulation and Red Team activities. These efforts will address the risks of a dynamic threat environment, to reduce technical, engineering, integration, test, and lifecycle cost risk. Finalize a comprehensive Survivability Certification Plan to continue, addressing nuclear survivability and hardening requirements. Continue to maintain emphasis on leveraging specialty engineering expertise across all disciplines to deliver a secure, reliable, and sustainable weapon system. This will be achieved through proactive processes, program-wide collaboration, and a focus on quality, timeliness, and cost-effectiveness.
Funding increased due to the risk reduction / parallel path efforts identified through the program restructure activities, TMRR efforts to achieve MS-B, and the EMD prime contract schedule incentive fee identified in the "Omni-Mod” contract framework.
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.

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.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 303.3 |
| FY2026 | Enacted | 395.9 |
| FY2027 | Request | 783.0 |
This activity is 17% of project 655238's FY2027 request and 17% 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.

Every R-2A line of this project, largest FY2027 request first. Linked where the activity has enough of its own narrative to carry a page; the rest are shown in full on the program-element page.
