What the FY2027 request buys
Verbatim from the R-2A exhibit for project 3051 of PE 0604234N. 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.
Complete transition of DSSC 5 Sensor Netting, Data Fusion, and Global Lightning integration effort to the E-2D fleet. Continue E-2D DSSC-6/Block II development of Flight and Mission computer hardware, National Technical Means (NTM), Open Mission Systems (OMS), and other associated obsolescence mitigation technical refresh efforts. Continue upgrade of developmental test aircraft, build-out of full-fidelity Systems Integration Lab (SIL) and conduct SIL Final Qualification Testing (FQT). Provide support of software development environments and integration labs required for E-2D software and hardware configurations. Systems engineering will support ongoing and emergent analysis and design/development/test efforts required to identify Engineering Change Proposal (ECP) requirements to respond to evolving and emergent threats to mission systems, communications systems, navigation equipment and countermeasures. Continue to support Advanced Development efforts to demonstrate and evaluate new hardware and software capabilities for future aircraft integration. Evaluate future capability expansions via studies and analyses.
Increase from FY2026 to FY2027 of $68.028 million due to ramp up of DSSC-6 Hardware development post Critical Design Review (CDR).
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
Continue developmental and integration efforts for DSSC-5 Sensor Netting, and transition DSSC 5 Sensor Netting second incremental build to E-2D Fleet. Continue DSSC-5 Data Fusion integration effort for fielding to the E-2D fleet. Continue DSSC-5 CEC and SDP software and hardware efforts. Continue DSSC-6 HECTR development. Continue development efforts for DSSC-6 TCID, to include Mission computer and Display hardware, National Technical Means (NTM), Open Mission Systems (OMS) and Multi-level Security architecture, and Communication as a Service (CaaS). Provide support of software development environments and integration labs required for E-2D software and hardware configurations. Systems engineering will support ongoing and emergent analysis and design/development/test efforts required to identify Engineering Change Proposal (ECP) requirements to respond to evolving and emergent threats to mission systems, communications systems, navigation equipment and countermeasures. Continue to support Advance Development efforts to demonstrate and evaluate new hardware and software capabilities for future aircraft integration. Evaluate future capability expansions via studies and analyses.
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 187.5 |
| FY2026 | Enacted | 215.9 |
| FY2027 | Request | 284.0 |
This activity is 73% of project 3051's FY2027 request and 73% of PE 0604234N'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.

Every R-2A line of this project, largest FY2027 request first. Linked where the activity has enough of its own narrative to carry a page; the rest are shown in full on the project page.
