The Air Force Research Laboratory has issued this fourth Request for Information to continue market research for the ASTROS II requirement, providing the final consolidated Industry Day Q&A responses and briefing materials. The government has completed its initial market research and will compete the eventual task order under the GSA OASIS+ Unrestricted vehicle in the Technical and Engineering Domain, Category 60206 (NAICS 541330) via GSA eBuy. Only contractors holding a prime contract on that specific OASIS+ domain and category will have access to the solicitation, draft documents, and future proposal submissions. The SAM.gov notice will remain active for 15 calendar days, from August 6 through August 21, 2026, for industry to download the final Q&A matrix, after which all activity moves exclusively to GSA eBuy. Industry question and feedback submission periods are now closed.
