The company said the B-21 is progressing rapidly through testing as it works to deliver enhanced long-range strike capability for the U.S. Air Force. Demonstrated aerial refueling allows the aircraft to operate globally and sustain extended missions.
“Our teams are moving the B-21 Raider through testing at an unprecedented pace, continually proving its outstanding performance – including aerial refueling,” said Tom Jones. “We’ve designed and built a reliable, adaptable aircraft that is vital to our warfighters’ missions, while operating with a sense of wartime urgency to accelerate production and deliver this capability.”
The addition of aerial refueling to the test program enables longer and more efficient flight sorties. It also supports continued evaluation of critical weapons systems and mission capabilities.
Northrop Grumman said the B-21 is designed as a highly fuel-efficient bomber, reducing reliance on tanker aircraft and enabling greater operational flexibility. This efficiency is intended to support mission planning and force deployment in complex operational environments.
The company has invested more than $5 billion in digital technologies and manufacturing infrastructure to support the program. These investments are aimed at accelerating production and preparing for initial aircraft delivery to Ellsworth Air Force Base in 2027.
Expanded production capacity is expected to provide flexibility to scale the fleet in line with future operational requirements. Northrop Grumman said this approach is intended to support long-term U.S. Air Force global strike capabilities.
The B-21 is described as the next evolution of the U.S. strategic bomber fleet, incorporating advanced stealth and mission systems. It is designed to deliver both conventional and nuclear payloads and operate across a wide range of mission profiles.
Multiple B-21 aircraft are currently undergoing flight testing, with most sorties achieving “code one” status, indicating readiness for subsequent flights without maintenance issues. The company said ongoing testing and manufacturing efforts are intended to validate performance and ensure readiness for operational deployment.
