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. This initiative aims to gather insights and feedback from industry partners to define the Army's future priorities for S/VTOL unmanned aircraft and explore potential Government Furnished Equipment (GFE) ecosystems for modular components. The Army is focused on articulating its desired characteristics for these platforms, fostering innovation and collaboration with industry to ensure successful integration of solutions that meet operational needs. Interested vendors are invited to submit white papers detailing their S/VTOL air-vehicle solutions by January 8, 2026, with submissions made through the ONI Marketplace at https://marketplace.gocolosseum.org. For further inquiries, contact Mark Martinez at mark.martinez2.civ@army.mil or Jordan Myers at jordan.m.myers7.civ@army.mil.
