This activity requests $11.1M in FY2027, 100% of project 090, down 0.1% on FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project 090 of PE 0603941D8Z. 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

In FY 2027, NT will continue to mature test technologies supporting the Department’s strategic goals of enabling radiation hardening and nuclear-survivable warfighting capabilities and accelerating strategic systems modernization. Highlights include: - Address SEE testing throughput needs - Continued development of new capability for combined radiation environment testing to include assembly integration and test. - Continued efforts in EMP testing to include development data acquisition systems tailored to ship based EMP survivability assessments

FY2026 to FY2027 change

The $0.010 million decrease from FY 2026 to FY 2027 is due to the completion of technology maturation efforts related to upgraded test environments for single event effects.

Before the request year

FY2025–FY2026: what came before

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

In FY 2026, NT will continue to mature test technologies supporting the Department’s strategic goals of enabling radiation hardening and nuclear-survivable warfighting capabilities and accelerating strategic systems modernization. Highlights include: - Continue efforts related to Single Event Effects (SEE) to include system test and commissioning for a heavy ion test facility - Continue efforts related to combined nuclear effects to include completion of Critical Design Review and initial acquisition of long lead components for neutron and gamma components - Continued efforts in EMP testing to include assembly and test of a horizontal EMP to ensure system survivability against Military EMP Standards

FY2025 accomplishments

In FY25, NT will continue to mature test technologies related to nuclear effects testing. Highlights include: - Continue Nuclear Test infrastructure gap analysis - Continue efforts in EMP testing to include large area source development and instrumentation - Continue efforts related to neutron testing - Initiate efforts in Single Event Effects - Initiate efforts related to combined nuclear effects

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 100% of project 090's FY2027 request and 0.3% of PE 0603941D8Z'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.
