## Summary

This activity requests $58.3M in FY2027, 6.9% of project 3097, down 4.7% 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

**FY2027 planned work.** - 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.

**FY2026 to FY2027 change.** 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.

## Before the request year

**FY2026 plans — current year.** - 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.
