The FY2019 budget request includes $633.9 million for Aeronautics Research, highlights for which include:
- “Advances aeronautics research that may lead to major advances in air traffic management intended to safely increase air traffic capacity, reduce flight delays, and enable safe, robust UAS integration.
- Completes the Critical Design Review for the Low Boom Flight Demonstrator X-Plane, which will demonstrate quiet overland supersonic flight and enable the creation of a new civil supersonic market for U.S. industry.
- Increases funding for fundamental research on hypersonics, improving the design of future hypersonic vehicles and enabling stronger collaboration with other government agencies and universities.
- Develops promising subsonic aircraft technologies that dramatically reduce fuel consumption, noise, and emissions enabling the U.S. aviation industry to maintain and advance its global leadership.”
