Interesting link indeed.

"One example of this is how we are managing hardware and software integration and testing. We are testing systems in representative mission environments using a flexible development platform with innovative use of modeling and simulation tools.

Most recently, we completed a demonstration with our flying test bed that validated the maturation of the B-21’s hardware and software integration progress. Demonstrations like these are what continue to build our customer’s confidence in our path to first flight.

And this isn’t the only example of where we are using a digital representation to burn down risk; far ahead of a traditional first flight, we have B-21’s “flying” in multiple lab environments on the ground and in the air, driving more time and cost out of traditional flight test."
