> With the F-117, the shape was part of the secret sauce. The B-21 doesn’t seem to be a big departure that way. The world has also changed substantially. When the F-117 was developed, being able to simulate the RF interactions with faceted geometry was ground breaking stuff. Now anyone that can afford an ANSYS license can simulate that with far, far, greater fidelity against much more complex shapes.
