What project 2573 buys
The F-35 Training Systems & Simulation Program Management Office (TSS PMO) development portfolio is aligned with the program's Continuous Capability Development & Delivery (C2D2) efforts and is organized in three primary lines of effort; Training System Capability Development (TSCD), Training Systems Architecture (TSA) Development, and Joint Simulation Environment (JSE) Development. Training System Capability Development (TSCD): Efforts will continue with a primary focus on alignment of Training System capabilities with other elements of the Air System. Specific efforts will include accelerating development of Block 4 capabilities to equivalent maturity of those in the Air Vehicle, continued development of the Production Runtime Server (PRTS) - Pilot Training Device TR-3 equivalent - to enable Block 4 capabilities, continued development of Live-Virtual-Constructive (LVC) capabilities including Distributed Mission Training (DMT), and appropriate lab infrastructure to enable Training System development. Training Systems Architecture (TSA) Development: Development efforts will continue to focus on modernization of activities outlined in the TSS PMO roadmaps that will target the requirement of bringing higher fidelity training to the warfighter. Specific development and testing efforts focus on software architecture modernization, hardware architecture modernization, and Synthetic Threat Enhancement. Joint Simulation Environment (JSE): Development, integration and testing efforts will continue to focus on keeping F-35 In-A-Box (FIAB) software concurrent with aircraft capabilities and injecting complex threat/sensor models to establish an operationally representative simulation environment required for operational test trial validity, and the completion of Verification, Validation and Accreditation (VV&A) activities for F-35 Block 4 modernization. Efforts will include FIAB development, fidelity and capability upgrades to existing threats/sensors/weapons models, development of new threat/sensor/weapon models, and environment upgrades to enable effective verification of Block 4 capabilities. Efforts will continue toward expansion of JSE capability to F-35 Training Sites. Funding allocations at the project level have historically been subject to change due to the complexity of the F-35 budget structure and cost share ratios.

Project 2573 funding, FY2025–FY2031
Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.

|---|---|---|
| FY2025 | Actual | 26.0 |
| FY2026 | Enacted | 32.0 |
| FY2027 | Request | 36.0 |
| FY2028 | Outyear | 31.3 |
| FY2029 | Outyear | 32.0 |
| FY2030 | Outyear | 32.2 |

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. 2 of them describe FY2027 work in enough detail to have their own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
Efforts will continue to support development, integration and test of Block 4 capabilities in the Training System with a focus on accelerating equivalent capability maturity between the Training System and other elements of the Air System and preparing relevant capability upgrades (Pilot Training, Maintainer Training, Instructional…

FY2026 to FY2027 change Considering FY2027 mandatory funding in addition to discretionary, the increase from FY2026 to FY2027 is due to TSS PMO ramping up efforts that are critical to delivering training devices to ensure Air System Alignment. TSS PMO will accelerate architecture development activities on the F-35 Lightning Integrated Training Environment (FLITE), which is a critical enabler to delivering Block 4 training capability.
FY2026 plans — current year Efforts will continue to support analysis, design, development, integration and test of Block 4 capabilities in the Training System with a focus on equivalent capability maturity between the Training System and other elements of the Air System and preparing relevant capability upgrades (Pilot Training, Maintainer Training, Instructional Products) for release to the fleet in FY2027. Additionally, F-35 Lightning Integrated Training Environment (FLITE) will continue critical development, integration and test activities with the first delivery expected in FY2028.

Named performers on project 2573
Performers named in the R-3 exhibit under this project. Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix. Budget-justification contract funding, not obligations.
