FY2026 award data is a partial year — USASpending awards are reported on a rolling basis and the fiscal year does not close until September 30. why partial FY2026 data? →

The vertical scale does not start at zero: the baseline sits just below this program’s smallest year, so a low point on this line is not a small amount. Read the shape for direction and the grid below for the figures.

Description
Mission — Joint Simulation Environment
Joint Simulation Environment (JSE) is the Air Force's synthetic solution for High-End Advanced Training, Tactics, and Testing (HEAT3). JSE supports operational plan rehearsals, large force exercises, and aircrew training events. This capability directly supports United States Air Force Warfare Center (USAFWC), United States Air Force Weapons School, Air Force Test Center (AFTC), Air Force Operational Test and Evaluation Center (AFOTEC), and augments platform training efforts that cannot be performed in open air. JSE encompasses, but is not limited to, lab facilities for development and experimentation, as well as multiple test and training locations, to include, but not limited to: Joint Integrated Test & Training Center Nellis AFB (JITTC-N), Digital Test & Training Range Nellis AFB (DTTR-N), Digital Test & Training Range Edwards AFB (DTTR-E), and future planned location JITTC-Joint Base Elmendorf-Richardson (JITTC-E). JSE Platform-In-A-Box (PIAB) Operational Flight Program (OFP) Based Simulator Development: Entails the study, evaluation, early experimentation, and development for platforms beyond the current/existing F-35 capability. Activities include analysis of OFPs against JSE software and interface standards, as well as common hardware standards enabling remote monitoring, updates, and security management. JSE Digital Test and Training Ranges (DTTR): Maintains and upgrades existing test capabilities, to include the continuation of installation, integration, and verification/validation activities in support of fielded and future platforms and virtual air threats. Furthermore, the 445 Test Squadron at DTTR-E manages Developmental Test (DT) and Operational Test (OT) events, as well as cyber testing integration for the JSE Enterprise as part of their Lead Developmental Test Organization (LDTO) designation. JSE Core Environment Development/Integration: Continues to develop JSE foundational capabilities enabling further test, integration, and training. Activities include but are not limited to experimentation, development/enhancement of JSE connected systems, tools, services, hardware, and simulators to integrate new and existing digital entities (platforms, sensors, adversary & friendly weapons, ground & airborne threats), and common services including but not limited to weather effects, infrared (IR) models, cyber, and space. Funding may also be used to address Diminishing Manufacturing Sources (DMS) issues, obsolescence resolution and similar emerging requirements, as well as for overarching programmatic support. Funding for this exhibit is contained in PE 0207606F. This requirement supports performance of a full financial audit as required by title 10 U.S.C. Chapter 9A, Sec 240-D. This program element may include necessary civilian pay expenses required to manage, execute, and deliver weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program element 0605829F, 0605831F, 0605833F, 0605898F. As this PE was established in FY 2025, FY 2024 civilian pay costs are not applicable, and in FY25 10.395M is forecasted for civilian pay expenses in this program element. This effort is in Budget Activity 4, Advanced Component Development and Prototypes (ACD&P), because efforts are necessary to evaluate integrated technologies, representative modes or prototype systems in a high fidelity and realistic operating environment.
Justification
Accomplishments & Planned Programs (3)
JSE Platform In-A-Box (PIAB) and Pilot Vehicle Interface (PIV) Hardware Simulator Development
Includes, but is not limited to, platform study, evaluation, and early experimentation activities to assess OFPs against JSE Government Simulator Interface (GSI) and Simulator Common Architecture, Requirements, & Standards (SCARS), and develop high-fidelity Platform OFP-based simulator and accompanying high-fidelity mission system and sensor models. Involves the evaluation and integration of new and emerging technologies including, but not limited to, Extended Reality (XR)/Virtual Reality (VR) goggle capability, artificial intelligence (AI), and common hardware solutions, to include common cockpit configurations for training-focused sites. Supports research and development activities to generate data/conduct analysis to support the integration and testing of platform OFP-based simulators.
JSE Digital Test and Training Ranges (DTTRs)
Maintains and expands existing test capabilities, to include platform installation, integration, and verification and validation activities at the DTTRs and the Joint Integrated Test and Training Centers (JITTCs). Supports ongoing day-to-day digital test range operations, JSE organic development capability, along with fielded and future Developmental Test & Evaluation (DT&E) and Operational Test & Evaluation (OT&E) activities. Establishes and expands on hardware in-the-loop testing capability, future platform testing capability, and continues early experimentation efforts.
JSE Core Environment Development/Integration
Continue the development of JSE capabilities enabling further test, integration, and training. Development activities are accomplished by leveraging Department of the Air Force (DAF) and Department of the Navy (DoN) organic software development capabilities at geographically separated locations using secure development enclaves across multiple classification levels enabling simultaneous developer access, known collectively as the JSE collaborative development environment. JSE collaborative development environment provides the foundation for secure digital collaboration, to perform development, security, and operations (DevSecOps) activities, manage development, share code, evaluate new capabilities, and distribute updated software versions to all connected locations. Costs include, but are not limited to, establishing equipment, personnel, processes, contracts, etc. to support JSE product development.

Oversight
Department-level designation (not specific to this program)
GAO lists 5 high-risk areas for DOD as a whole. That designation covers the department, not Joint Simulation Environment (JSE) — no program-specific GAO finding for this line is in the ingested data. See the DOD oversight record.
No research dossier for this program — dossiers cover 50 of 1,741 programs, the largest fully J-book-detailed lines by FY2026 requested dollars. why no dossier here? →
