Novel Propulsion Solutions for the Very Low Earth Orbit (VLEO) Regime

The U.S. Space Force (USSF) is seeking innovative propulsion solutions for Very Low Earth Orbit (VLEO) operations through its Small Business Innovation Research (SBIR) program. The objective is to advance propulsion technologies that enable sustained space operations in the VLEO regime, addressing challenges such as high atmospheric drag and dynamic orbital variations. This initiative is crucial for enhancing the Department of the Air Force's capabilities in space operations, particularly in intelligence, surveillance, reconnaissance, and communications. Interested applicants must prepare proposals demonstrating a proven technology ready for Phase II, with a focus on feasibility studies and integration pathways, as the solicitation opens on May 28, 2025, and closes on June 25, 2025.
