From top Air Force acquisition executive William LaPlante:

According to LaPlant, the project was designed so that bombers could be easily upgraded when new technology emerges or new requirements are written.

He said the bomber would have a few components that were now being used in secret programs and that “just because they are existing (or) mature doesn’t mean that they are in the open, doesn’t mean that any of you even know about them”.
