## What project 1427 buys

The Department's submission reflects the results of a deep dive into Fleet Training Wholeness (FTW) and how to provide a means for Strike Group Training in a contested environment, in accordance with Chief of Naval Operations guidance. This analysis determined the most cost-effective means to provide this training is via a combination of Live, Virtual, Constructive (LVC) capabilities, which are essential for building a force that has overmatch. LVC capabilities leverage combat system product line architecture components and engineering best practices for iterative development. The deep dive identified that there is no other cost-effective way to train our ready warfighters for a contested environment. The foundation for LVC has already been established and will continue to execute the investment strategy to provide initial underway LVC capability to train Strike Group(s) in an environment that they expect to fight in, ensuring they are fit to fight and win. The development, integration and testing of LVC's, along with ensuring interoperability with surface and air communities, will be accomplished across Integrated Warfare Systems (IWS), and Navy Continuous Training Environment (NCTE). Surface Tactical Team Trainer (STTT) develops modifications during sustainment of Battle Force Tactical Training (BFTT) system and modernization into the Advanced Training Domain (ATD). Both BFTT and ATD are the core systems that are used to integrate weapon system elements, and combat system components to create the Total Ship Training Capability (TSTC). BFTT and ATD continue to integrate and update, as new tactical capabilities are being introduced, to enable crew operator proficiency training for basic and sustainment level training events, through distributed strike group certification fleet synthetic training (FST) events and including Composite Training Unit Exercise (COMPTUEX) FST underway LVC events. Continued development is required to integrate new capabilities and interfaces to provide training for AEGIS and Ships Self Defense System (SSDS) combat system capability upgrades, and to address the Fleet's LVC FTW initiative.

**R-3 lines of work:** Product Development; Test and Evaluation; Management Services.

### Surface Tactical Team Trainer (STTT)

**FY2027 planned work.** Continue development, integration and testing ATD with AEGIS and SSDS to continue alignment with evolving combat system builds. Continue development and integration of ATD to incorporate training capabilities to support AEGIS and SSDS tactical capability updates. Continue development and delivering threat database updates to enable ships crews to train to relevant near-peer threats.

**FY2026 to FY2027 change.** The decrease of $1.594M from FY26 to FY27 due to legacy ATD builds begin moving from active development into sustainment.

**FY2026 plans — current year.** Continue development, integration and testing ATD with AEGIS and SSDS to continue alignment with evolving combat system builds. Continue development and integration of ATD to incorporate training capabilities to support AEGIS and SSDS tactical capability updates. Continue development and delivering threat database updates to enable ships crews to train to relevant near-peer threats. Complete the development of Surface LVC Position Reporting (SLPR) capability for BFTT.
