### NSTTC

**FY2027 planned work.** In FY 2027, funds transferred to new Program Element 1206617SF, Project 644441 Operational Test & Training Infrastructure.

**FY2026 to FY2027 change.** FY 2027 decrease of 149.505 million was a result of funds transferred to new Program Element 1206617SF, Project 644441 Operational Test & Training Infrastructure.

**FY2026 plans — current year.** - Continue investments in Cyber, Electromagnetic, and Orbital ranges, including foundational infrastructure development as well as modernization and improvement of existing capabilities to keep current with military priorities, evolving threats, and advanced training involving USSF and joint systems and operations - Continue development of Electromagnetic Spectrum range Command, Control, and Communication (C3), terminal, data generation systems - Continue support to warfighting community of Electromagnetic Warfare (EW) advanced training environment - Continue development of integrated data transport architecture across the ranges - Continue developing digital High-End Advanced Test, Training, and Tactics Development (HEAT3) platform to enable enduring Joint Simulation Environment (JSE)-based digital test and training architecture - Deliver Minimum Viable Product (MVP)-level digital HEAT3 platform for initial JSE integration; deliver and integrate initial set of intel-validated threat models, enabling HEAT3 platform to support test and training relevant to top-priority DoW threat scenario - Continue development of advanced and combat training capabilities for exercises and wargames. Deliver MVP medium fidelity digital capability to support evolved Space Flag requirements. - Continue development of digital range operations via Commercial Solutions Openings (CSOs)

## What is NOT on this page

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
