The first contract is the Aerospace Systems Technology Research and Assessment (ASTRA) Aerospace Technology Development and Testing (ATDT) for conducting research, development, and demonstration of transformative aerospace capabilities and multi-domain operations (MDO) modeling, simulation, and analysis (MS&A). The ATDT contract (FA8650-21-D-2602) is awarded with one initial task order (FA8650-21-F-2603) for control automation research with a price of $16,949,999. The second contract (FA8650-21-D-2606) is for the ASTRA Multi-Domain Modeling, Simulation, and Analysis (MDMSA). The MDMSA contract will focus on MDO MS&A tool development and MDO analysis. The MDMSA contract is awarded with two initial task orders: one task order (FA8650-21-F-2604) for advanced high-speed operations and analysis research with a price of $6,400,000; and one task order (FA8650-21-F-2605) for multi-domain technology simulation-based engineering with a price of $14,771,892. Work will be performed at Wright-Patterson Air Force Base, Ohio, for both contracts and both are expected to be completed May 1, 2028. This award is the result of a competitive acquisition and four offers were received. Fiscal 2021 research, development, test and evaluation funds in the amount of $2,267,501 will be obligated at the time of award on the first task order. The Air Force Research Laboratory, Wright-Patterson AFB, Ohio, is the contracting activity.
