The U.S. Army is issuing an open, enduring call for up to five years to competitively onboard innovative, commercially available Group 3 Uncrewed Aircraft Systems (UAS) onto its UAS Marketplace. The goal is to evaluate systems through a three-step process—initial capability assessment, verification, and full proposal—and establish Firm-Fixed-Price Basic Ordering Agreements (BOAs), though award does not guarantee future orders. Offerors must meet eligibility requirements including NDAA compliance, SAM.gov registration, NIST SP 800-171 assessment, and potential CMMC cybersecurity standards. Systems should be production-ready or at least Technology Readiness Level 7, with missions such as reconnaissance, electronic warfare, communications relay, and cargo delivery. No budget amounts or specific performance locations are specified; demonstrations may be held at government-selected locations or virtually.
