The Department of Defense, specifically the U.S. Army, is seeking industry participation in the Group 4+ UAS | Short/Vertical Takeoff and Landing (S/VTOL) Challenge to address the obsolescence of legacy platforms in Multi-Domain Operations. The initiative aims to establish a collaborative engagement with industry partners to communicate the Army's desired characteristics for S/VTOL platforms while gathering feedback on their viability and the integration of Government Furnished Equipment (GFE) components. This challenge is crucial for defining future priorities for S/VTOL unmanned aircraft and exploring potential modular component ecosystems, thereby fostering innovation in defense capabilities. Interested vendors are invited to submit white papers by January 8, 2026, detailing their S/VTOL solutions, and must demonstrate possession of Cybersecurity Maturity Model Certification (CMMC) Level 2 to obtain specific desired characteristics. For further inquiries, vendors can contact Mark Martinez at mark.martinez2.civ@army.mil or Jordan Myers at jordan.m.myers7.civ@army.mil.
