This activity requests $25.8M in FY2027, 22% of project 675200, up 11% 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 675200 of PE 0303140F. 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

KGV-363 - Will continue development of Crypto Module with SERD 2.0 implementation, required for NSA. - Will complete milestones under SERD 2.0: Critical Design Review (CDR), Test Readiness Review (TRR). KG-333 - Will continue development of Crypto Host with SERD 2.0 implementation, required for NSA. - Will complete milestones under System Requirements Review (SRR), System Functional Review (SFR).

FY2026 to FY2027 change

Overall funding increase for the combination of development for the KGV-363 under SERD 2.0 and full year development of the KG-333(M). KGV-363 will be continuing efforts to complete the development effort including conducting milestones mentioned in the FY 2027 plan as well as beginning testing and evaluation in FY 2027. Meanwhile the KG-333(M) will have a full year of development in FY 2027 after a late FY 2026 contract award and is projected to complete SRR and SFR and will work towards finalizing approval of documents needed to enter Preliminary Design Review (PDR) FY 2028.

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

KGV-363 - Continue development of Crypto Module with SERD 2.0 implementation, required for NSA. - Complete milestones under System Requirements Review (SRR), System Functional Review (SFR), Preliminary Design Review (PDR). KG-333M - Award development contract in FY 2026 fourth quarter.

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 22% of project 675200's FY2027 request and 22% of PE 0303140F'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.
