What the FY2027 request buys
Verbatim from the R-2A exhibit for project 3097 of PE 0101221N. 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.
- Execute full-scale software development and missile system engineering for W93/Mk7 integration with all variants of the SWS. - Update Fire Control/Missile/Reentry performance characteristics and missile system requirements to accommodate Mk7 capabilities and specifications. - Execute FCET-9 flight test with Mk7 development test bodies to collect critical development flight test data collection. - Conduct ground system testing, analysis, and design compliance verification for W93/Mk7 integration performance and missile system requirements. - Update drawings, procedures, and system documentation for integrated weapon system operations and maintenance. - Design support equipment for W93/Mk7 production, handling, operations, and SWF integration. - Procure and refresh Flight Test Instrumentation (FTI) equipment and spares as necessary to mitigate reliability/availability risks and ensure rapid development flight test data capture. - Conduct system safety activities and production planning for integrated W93/Mk7 weapon system and DoW hardware production.
The funding decrease of $2.863 million from FY 2026 to FY 2027 reflects the program's planned progression, as resources are reprioritized toward enhanced arming and fuzing capabilities. Key activities in this phase include full-scale software development and missile system engineering for W93/Mk7 integration, the execution of the FCET-9 flight test to collect critical data, and comprehensive ground system testing. Efforts will also continue on updating system documentation, designing support equipment, and procuring flight test instrumentation to ensure program milestones are met.
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 software development for flight controls. - Conduct ongoing systems engineering analyses to ensure the RBA design is fully compatible with the Trident II missile system and meets all performance requirements. - Manage the interfaces between the RBA and missile subsystems, ensuring seamless communication and coordination during all phases of flight. - Develop and implement comprehensive integration plans, including detailed test procedures and acceptance criteria, to verify proper integration and functionality. - Develop and refine the communication protocols and data interfaces required for seamless integration between the RBA and the Fire Control system. - Synchronize system architecture and development milestones with the Fire Control program by defining and validating all critical system interfaces to guarantee seamless interoperability and functional compatibility. - Participate in joint testing and simulations to validate the integrated performance of the RBA and Fire Control system under realistic operational conditions. -System engineering and integration efforts in support of FY 2026 and FY 2027 Flight test.
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 | 5.9 |
| FY2026 | Enacted | 61.2 |
| FY2027 | Request | 58.3 |
This activity is 6.9% of project 3097's FY2027 request and 5.5% of PE 0101221N'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.
