Joint Simulation Environment
Abstract
In FY 2025, PE 0207142F, F-35 Squadrons, Project 675346, F-35 efforts were transferred to PE 0207606F, Joint Simulation Environment (JSE), Project 642407, Joint Simulation Environment, in order to consolidate all JSE funding under one PE 0207606F. This is not a new start. In FY 2025, PE 0207605F, Wargaming and Simulation Centers, Project 672888, Distributed Mission Operations Center (DMOC) efforts were transferred to PE 0207606F, Joint Simulation Environment (JSE), Project 642407, Joint Simulation Environment, in order to consolidate all JSE funding under one PE 0207606F. This is not a new start. Joint Simulation Environment (JSE) is the Air Force's integrated digital test and training range solution, enabling multi-platform, multi-domain interoperability via a government-owned-and operated architecture. It incorporates models for current and next-generation threats, a physics-based environment, and simulators employing platform Operational Flight Program (OFP) software. JSE supports developmental and operational testing, High-End Advanced Tactics, Training, and Testing (HEAT3), operational plan rehearsals, large force exercises, and aircrew training events. This capability directly supports USAF Warfare Center, USAF Weapon School, Air Force Test Center (AFTC) and Air Force Operational Test and Evaluation Center (AFOTEC) test requirements, and platform training enclaves that cannot train or test in open air due to operational security (OPSEC) and the inability to adequately simulate operations in the real world. JSE encompasses, but is not limited to, lab facilities for development and experimentation, as well as multiple test and training locations: Joint Integrated Test & Training Center Nellis AFB (JITTC-N) (previously known as the Virtual Test & Training Center (VTTC)), Digital Test & Training Range Nellis AFB (DTTR-N), Digital Test & Training Range Edwards AFB (DTTR-E), and future planned location JITTC-E (Joint Base Elmendorf-Richardson). JSE Platform-In-A-Box ("PIAB - OFP Based Simulator) Development: Entails the study, evaluation, early experimentation, and development for platforms beyond the current/existing F-35 Initial Operational Test & Evaluation (IOT&E) capability. Activities include early analysis of platform Operational Flight Program (OFP) 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: 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 (VATS). 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 and enhance new and existing digital entities (platforms, sensors, adversary & friendly weapons, ground & airborne threats), blue weapons models, manned airborne threat simulators, 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. The JSE Enterprise intent is to replicate the digital test and training range capability at multiple test and training locations. 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 0605827F, 0605828F, 0605829F, 0605831F, 0605832F, 0605833F, 0605898F, 0606398F. As this PE was established in FY 2025, civilian pay costs in FY 2023 and FY 2024 are non-applicable. 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.
