The U.S. Army seeks industry solutions to modernize its Synthetic Training Environment (STE) by delivering a Virtual Software (VSW) suite that enables live‑fire gating, combined‑arms training, mission‑command concurrency, and an open, extensible architecture. The effort is split into five “Lots” covering core software platform (Lot 1), plug‑in applications (Lot 2), hardware‑in‑the‑loop integration (Lot 3), training‑management & AAR data (Lot 4), and enterprise integration support with a dedicated Software Integration Laboratory (Lot 5). Offerors may submit for any lot(s) subject to conflict‑of‑interest restrictions. The solicitation includes an industry day (22‑24 Sep 2026), a solution‑brief deadline (29 Sep 2026 1300 EDT), down‑select notifications (2 Oct 2026), demonstration pitches (20‑22 Oct 2026), and award notification (13 Nov 2026). The total estimated value of all lots is about $250 M.
• Four core capability outcomes: doctrinal gate to live fire, true combined‑arms environment, full mission‑command concurrency, open SDK/APIs.
• Lot 1: Common Core Software – open architecture, 60 Hz simulation tick, 90 Hz rendering, 50 k entities, SDK/API delivery.
• Lot 2: Simulation Applications – unlimited plug‑in apps, “app‑store” model, open‑source SDK use.
• Lot 3: HIL Integration – connect RVCT hardware to virtual engine via HAPI/HAL.
• Lot 4: Training Management & AAR – ingest event data, generate automated after‑action reviews.
• Lot 5: Enterprise Integration Support – provide and operate a secure Orlando‑based Software Integration Laboratory (SIL), manage DevSecOps pipeline, conformance testing, and network infrastructure (IL‑4/5).
• Key dates: Draft posting 27 Aug 2026, Q&A 27 Aug‑13 Sep 2026, Final posting 15 Sep 2026, Industry Day 22‑24 Sep 2026, Solution due 29 Sep 2026, Awards 13 Nov 2026.
• Required maturity: TRL 8/9, open‑systems, One‑World‑Terrain ingestion, cyber‑secure, AI‑assisted development.
