Lockheed may have completed a prototype hypersonic SR72
Jack O’Banion, Vice President of Strategy and Customer Requirements, Advanced Development Programs for Lockheed Martin, at a presentation said that the SR72 could not have been made without digital transformation. This seems to indicate that a hypersonic vehicle has been built.

The SR72 is a mach 6+ hypersonic precision bomber that can also act as a spyplane.
