What the FY2027 request buys

Verbatim from the R-2A exhibit for project 0993 of PE 0604504N. 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

Procure (V)3 EDM and begin Engineering Change Proposal (ECP) development for the AN/SPN-50(V)3 to address component obsolescence; the (V)2 is no longer procurable after FY27. The (V)3 ECP will replace obsolete parts and integrate modern software solutions that enhance performance and interoperability with other systems. ECP will also continue development to mitigate evolving cyber vulnerabilities, paramount to safeguard the AN/SPN-50 from increasingly sophisticated threats, protecting sensitive data and maintaining operational integrity. The (V)3 ECP is vital for maintaining operational readiness, addressing new technological advancements, and ensuring the long-term effectiveness of the system for its intended lifespan.

FY2026 to FY2027 change

FY27 funding increase is to begin development for the AN/SPN-50(V)3 and procure 1 EDM.

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

Funds development of ECP for the AN/SPN-50. These efforts will address obsolescence and corresponding software integration. Continued development efforts to mitigate evolving cyber vulnerabilities.

Money

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 86% of project 0993's FY2027 request and 53% of PE 0604504N'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.
