80JSC023DA010, Simulation and Software Technology (SST) III Ceiling Increase

NASA’s Johnson Space Center is seeking to increase the ceiling of its existing Simulation and Software Technology (SST) III Indefinite‑Delivery‑Indefinite‑Quantity contract with CACI‑Federal, Inc. to support critical human‑spaceflight programs (ISS, Artemis, Orion, Gateway, etc.). The sole‑source modification adds $75 million to the contract ceiling, allowing continued delivery of advanced simulation, virtual reality, modeling, and software engineering services through the contract’s performance period ending September 30 2027. The effort includes development and support of Trick simulation models, VR/AR crew training, flight software verification, guidance‑navigation‑control tools, and integrated robotics and vehicle‑system management applications. • Existing IDIQ (SST III) with Cost‑Plus‑Fixed‑Fee and Firm‑Fixed‑Price task orders • Ceiling increase from $150 M to $225 M to meet rising demand • Services: simulation, VR/AR, software engineering, flight software, GNC, robotics, model integration • Supports ISS, Orion MPCV, Artemis, Gateway, Moon Base, and other exploration programs • Period of performance: Oct 1 2022 – Sep 30 2027 (remaining ~5 years) • Sole‑source award to incumbent CACI‑Federal, Inc.; no competitive alternatives identified • Submission of capabilities/qualifications due June 26 2026 (4 p.m. Central)
