Overview
- An operational test pilot from AFOTEC Detachment 5 flew in the B-21 alongside a developmental test pilot, a step the Air Force announced on June 11 that marks the earliest DT/OT cockpit pairing in modern U.S. aircraft testing.
- The joint flights shift the program from pure flight performance checks to mission-systems, weapons integration and combat-utility assessments that place warfighter feedback directly into the test loop.
- The Department of the Air Force and Northrop Grumman agreed on February 23 to apply $4.5 billion to raise annual B-21 production capacity by 25 percent, making early detection of design or interface problems more urgent to avoid costly retrofits.
- Program leaders say the move reflects a deliberate acquisition culture change to speed fielding; the Air Force still plans initial operational fielding at Ellsworth Air Force Base in 2027 and a minimum inventory objective of 100 aircraft.
- The combined test approach leverages two flying test articles, digital engineering and integrated test teams so issues are found sooner, which could cut later schedule slips and reduce the number of crews affected by post-production fixes.
