This activity requests $18.0M in FY2027, 100% of project 3238, down 9.5% 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

Verbatim from the R-2A exhibit for project 3238 of PE 0605863N. 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

Sustainment: -Continue Support and Sustainment (S&S) of 15 Threat Models that remain in continued use. Periodic refinement and update of models are required due to continued evolving threats. Development and Integration: -Continue to provide support for the integration and use of threat products (ATEP) in various combat system testbeds for use in Developmental and Operational Testing (DT/OT). Supported ship classes include: (but not limited to) DDG FLT IIA/III, and preparation for SSDS Baseline 12 Ships (CVN 79, LPD FLT II, LHA 8). -Continue Development and Integration of 15 Threat Models to support DT and OT events. -Continue integrating new and updated threat products (ATEPs) into M&S Testbeds to support DT and OT. Supported ship classes include but are not limited to: DDG FLT IIA/III, and preparation for SSDS Baseline 12 Ships (CVN 79, LPD FLT II, LHA 8). -DDG FLT III: Continue developing 6 threat products (ATEPs, New Versions) and updating 11 existing threat products (ATEPs, via S&S). -SSDS Baseline 12 Ships (CVN 79, LPD FLT II, LHA 8): Continue developing 6 threat products (ATEPs) and sustaining 11 existing threat products (ATEPs). -SEWIP (EWTB): Continue developing 1 threat product (ATEPs) and sustaining 5 existing threat products (ATEPs). Test & Evaluation Support: -Provide required support for AEGIS Baseline 10.0/FLTIII and SLQ-32 V (7) (SEWIP Blk 3) M&S Testbed DT. -Provide continued support and preparation for SSDS Baseline 12 Ships (CVN 79, LPD FLT II, LHA 8).

FY2026 to FY2027 change

$1.896M reduction from FY 2026 to FY 2027 reflects a reduction in FY 2027 threat product features.

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

Sustainment: -Continue Support and Sustainment (S&S) of 10 Threat Models that remain in continued use. Periodic refinement and update of models are required due to continued evolving threats. Development and Integration: -Continue to provide support for the integration and use of threat products (ATEP) in various combat system testbeds for use in Developmental and Operational Testing (DT/OT). Supported ship classes include: (but not limited to) DDG FLT IIA/III, and preparation for SSDS Baseline 12 Ships (CVN 79, LPD FLT II, LHA 8). -Continue Development and Integration of 10 Threat Models to support DT and OT events. -Continue integrating new and updated threat products (ATEPs) into M&S Testbeds to support DT and OT. Supported ship classes include but are not limited to: DDG FLT IIA/III, and preparation for SSDS Baseline 12 Ships (CVN 79, LPD FLT II, LHA 8). -DDG FLT III: Continue developing 8 threat products (ATEPs, New Versions) and updating 6 existing threat products (ATEPs, via S&S). -SSDS Baseline 12 Ships (CVN 79, LPD FLT II, LHA 8): Continue developing 5 threat products (ATEPs) and sustaining 6 existing threat products (ATEPs). -Electronic Warfare Test Bed: Continue developing 1 threat product (ATEPs) and sustaining 4 existing threat products (ATEPs).

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 100% of project 3238's FY2027 request and 11% of PE 0605863N'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.
