Synthetic Training Environment (STE) Virtual Software (VSW)

The U.S. Army is issuing a multi‑lot Call for Solutions to modernize its Synthetic Training Environment through a Virtual Software (VSW) ecosystem. The effort is split into five independent lots covering a common‑core simulation engine, plug‑in applications, hardware‑in‑the‑loop integration, training‑management & after‑action review analytics, and an enterprise integration/support team. Offerors must provide a TRL 8‑9, open‑architecture solution with native One‑World Terrain support, meet strict cybersecurity (STIG, RMF) requirements, and comply with an organizational conflict‑of‑interest firewall for Lot 5. The program ceiling is roughly $250 M, with a 9‑month prototype phase followed by optional multi‑year extensions. Key milestones include Industry Day (22‑24 Sep 2026), solution‑brief deadline (29 Sep 2026), demonstration pitches (Oct 2026), and award (Nov 2026). • Five separate lots allow vendors to specialize (core engine, apps, HIL, analytics, integration). • Mandatory anonymous technical concept (5‑page limit) and a 5‑minute product demo video. • Strict OCI rules prevent any entity from receiving both Lot 5 and any software lot. • Government‑furnished TSS source code and RVCT hardware will be provided on external media; vendors must sign a distribution agreement.
