The Department of Defense, specifically the Navy, is seeking innovative solutions through the Small Business Innovation Research (SBIR) program to increase the unrefueled combat radius of naval tactical aircraft. The objective is to identify and validate methods that could enhance aircraft performance, focusing on areas such as propulsion modifications, fuel efficiency, and weight reduction, with the goal of achieving Technology Readiness Levels (TRL) 3 and 4-5 across two phases of development. This initiative is crucial for enhancing the operational capabilities of naval forces, particularly in delivering long-range fire support. Interested parties should note that the solicitation will open on April 23, 2025, and close on May 21, 2025, with further details available at the provided source link.
