One of the U.S. Air Force’s top acquisition programs, the Northrop Grumman B-21 Raider, will complete its critical design review (CDR) by year’s end, a senior official says.
Randall Walden, Air Force Rapid Capabilities Office director, said June 25 at a Mitchell Institute Event that the service has completed the preliminary design review (PDR) and will soon formally kick off a CDR.
Once the program passes its CDR, the service will move onto manufacturing a test aircraft, he said.
“This is about building 100 bombers, not about getting through development,” Walden said. “My focus is getting production started, but we can’t get through that until we understand what the design looks like.”
In March, House Armed Services seapower and projection forces subcommittee Chairman Rep. Rob Wittman (R-Va.) told reporters there were a series of early production “hiccups” with the next-generation stealth bomber’s engine and wings. The problem Wittman described about the B-21 engine is related to airflow.
“This is an extraordinary, complex aircraft,” Wittman said. “The issue is not that you have uncertainties, the issue is how you address them.”
Walden said the problems Wittman mentioned in March are fixed. The program experienced these hurdles because everything produced at that point was built on predictions, he said. But the program office is currently conducting component-level testing and now has a good feeling for each part.
