## What project 0409 buys

This project provides Test and Evaluation (T&E) requirements for DDG-51 Flight III ships and efforts for the Navigation, Aviation and Hull, Mechanical & Electrical (HM&E) Cyber Enclaves Design for implementation on future new construction ships. T&E will concentrate on verifying integration and interoperability of employed technologies and systems in the DDG-51 FLT III design to achieve the mission capabilities and performance requirements as defined in the DDG-51 Flight III Capability Development Document (CDD) to reach Initial Operational Capability (IOC). T&E functions will include the evaluation of Critical Technical Parameters (CTP), Measures of Effectiveness (MOE), Measures of Suitability (MOS), and Key Performance Parameters (KPP). Funding is also planned for the execution of Developmental Testing (DT), Operational Testing (OT), Live Fire Test and Evaluation (LFT&E), and Full Ship Shock Trials (FSST). The Navigation, Aviation and Hull, Mechanical & Electrical (HM&E) Cyber Enclaves Design effort will provide a new design to physically separate Hull, Mechanical, and Electrical (HM&E) communications from Navigation communications to meet multiple DoD Directives/Instructions on Cybersecurity and Navy Joint-SYSCOM Cybersecurity Standards on Enclave management. This design will be utilized to support implementation on future new construction DDG-51 class ships.

**R-3 lines of work:** Product Development; Test and Evaluation.

### DDG-51 Flight III Test and Evaluation

**FY2027 planned work.** Continue Modeling and Simulation in support of Final Safety Analysis Report (FSAR) models and Verification, Validation & Accreditation (VV&A) development. Continue test plan preparation to execute Conduct Failure and Recoverability Mode (FARM) Testing (FARM) Testing on DDG 128 in FY27. Finalize FSST ship repairs and report. Continue execution of IOT&E campaign on DDG 125 and the Live Fire Test and Evaluation Program.

**FY2026 to FY2027 change.** Decreased of $16.194M from FY26 to FY27 due to completion of Full Ship Shock Trials (FSST).

**FY2026 plans — current year.** Continue Modeling and Simulation (M&S) efforts and model updates. Continue M&S runs for the record and analysis, test plan development and execution of FARM testing and complete development of the Initial Survivability Assessment Report (ISAR). Continue formal planning and execute the Full Ship Shock Trials (FSST). Continue execution of Developmental Testing (DT) and Live Fire Test and Evaluation (LFT&E). Begin execution of the Initial Operational Test & Evaluation (IOT&E) plan.

### Navigation, Aviation, and Hull Mechanical & Electrical (HM&E) Cyber Enclaves Design

**FY2026 to FY2027 change.** Decreased of $1.275M from FY26 to FY27 due to program phased out.

**FY2026 plans — current year.** Continue to execute system development based on completion of Critical Design Review (CDR) in FY 2025. Complete verification and validation testing. Includes test site Adaption Data (AD) Kit development, complete Network Management Group (NMG) Shock and environmental testing.

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
