## Summary

This activity requests $99.5M in FY2027, 100% of project 3068, down 32% 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.** - Continue developing modeling and simulation tools to support countermeasure versus threat performance assessments - Continue execution of IPTs to support requirements, systems engineering, testing, and product support - Coordinate and conduct government led testing events; Support the development of test procedures and testing facilities, monitor and engage in Prime Contractor performance, attend and provide technical support for Contractor-led testing events, and assess all testing outcomes for effectiveness - Utilize modeling and simulation tools to support threat and countermeasure performance assessment - Start development of an advanced Block 1 Countermeasure model to support modeling and simulation activities enabling larger system of system simulations - Continue technical and contractual planning activities for the LEED Block 1 Countermeasure, Decoy Launching System, and Launcher - Continue technical and contractual planning activities for the LEED Block 2 Payload and Countermeasure - Continue planning and execution activities for the transition to major capability acquisition for initial production, including preparation for a milestone decision - Continue development and integration of Countermeasure tactics, SKCS control algorithms and controller software - Complete system design improvements progressing the prototype system towards full requirement compliance - Commence planned improvement to the LEED Block 1 Countermeasure - Continue SKCS SW improvements to utilize capability of LEED system - Continue system of systems EW interoperability, integration and testing activities - Continue SKCS SW backfit development to support system deployment on older baselines - Continue SKCS SW development to enable system deployment on Integrated Combat System (ICS) baselines - Continue development of training and maintenance materials and curriculum - Continue development of the LEED Block 2 payload - Complete initial prototype shipset hardware procurement for shipboard installation

**FY2026 to FY2027 change.** FY26 to FY27 decrease algins with completing procurement and delivery of the first prototype shipset, development of the Block 2 payload, and the transition of the LEED Middle Tier Rapid Prototype program to a major capability acquisition ready for initial production of the LEED Decoy Launching System, Launcher and Block 1 Countermeasure.

## Before the request year

**FY2026 plans — current year.** - Continue developing modeling and simulation tools to support threat and countermeasure performance assessments. - Continue execution of an IPT to support requirements, systems engineering, testing, and product support: Coordinate and conduct government led testing events; Support the development of test procedures and testing facilities, monitor and engage in Prime Contractor performance, attend and provide technical support for Contractor-led testing events, and assess all testing outcomes for effectiveness; Utilize modeling and simulation tools to support threat and countermeasure performance assessments; Commence ship design and ship integration planning activities. - Continue technical and contractual planning activities for integrated LEED Countermeasure development. - Continue planning and execution activities for the transition to major capability acquisition for initial production, including preparation for a milestone decision. - Continue development and integration of Countermeasure tactics, SKCS control algorithms and controller software. - Complete development of government test measurement assets needed for DT events. - Complete the DT (Developmental Testing) of Cyber Security, Vibration, and FQT (Functional Qualification Test) - Continue system design improvements progressing the prototype system towards full requirement compliance. - Execute combined Final Qualification Test and Quick Reaction Assessment (QRA). - Continue SKCS SW improvements to utilize capability of LEED system. - Start SKCS SW backfit development to enable system deployment on older Aegis baselines. - Start SKCS SW development to enable system deployment on SSDS or Integrated Combat System (ICS) baselines. - Start systems of systems EW interoperability, integration, and testing initiatives. - Continue development of training and maintenance materials and curriculum. - Continue the DT (Developmental Testing) including Electromagnetic Interference (EMI), chamber test, Radar Cross Section (RCS), Land Based Testing (LBTS)-Maintenance Demo (Mdemo), and at-sea prototype demo testing. - Conduct and complete development and material purchases required to deliver shipset(s) to the fleet including All Up Rounds (AUR). - Commence development of LEED Block 2 AUR payload.
