Overview
- An operational test pilot flew in the B-21 cockpit alongside a developmental test pilot in a flight disclosed in mid‑June, marking the first time the two roles have flown together so early in a modern U.S. program.
- Service officials describe the flight as the earliest integration of developmental testing and operational testing in modern practice, shifting evaluation from simply proving the jet can fly to testing whether it can fight.
- The decision to add early operational input follows recent test progress including arrival of a second test aircraft in September 2025 and first aerial refueling trials in April 2026.
- The Raider Combined Test Force, which mixes Air Force developmental testers, AFOTEC operational evaluators and Northrop Grumman engineers, will use near‑real‑time feedback to pinpoint crew‑interface and weapons issues for faster fixes.
- Leaders link the move to a February agreement to apply $4.5 billion to boost production capacity by 25 percent and to plans for initial fielding around 2027, but analysts warn faster schedules can raise the risk of costly retrofits if defects are missed.
