## Summary

This activity requests $18.1M in FY2027, 45% of project 1427, up 2.8% 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 to conduct systems engineering and development activities to integrate Surface Training Program (STP) (formerly Surface Training Advanced Virtual Environment (STAVE)) high fidelity simulations and the Advanced Training Domain (ATD) Live, Virtual and Constructive (LVC) Training Capability within the Integrated Combat System (ICS) Infrastructure as a Service (IaaS) computing, networking and displays, high fidelity Combat System Simulator/Stimulators to enable realistic training within a contested environment, leveraging concepts and lessons learned from LVC integration efforts conducted in fleet training wholeness.

**FY2026 to FY2027 change.** The increase of $0.486M from FY26 to FY27 reflects commensurate development efforts with slight increase for inflation.

## Before the request year

**FY2026 plans — current year.** Continue to conduct systems engineering and development activities to integrate Surface Training Program (STP) (formerly Surface Training Advanced Virtual Environment (STAVE)) high fidelity simulations and the Advanced Training Domain (ATD) Live, Virtual and Constructive (LVC) Training Capability within the Integrated Combat System (ICS) Infrastructure as a Service (IaaS) computing, networking and displays, high fidelity Combat System Simulator/Stimulators to enable realistic training within a contested environment, leveraging concepts and lessons learned from LVC integration efforts conducted in fleet training wholeness.
