B-21 Raider fast-tracks long-range strike capability

The U.S. Air Force’s B-21 Raider has completed aerial refueling from a KC-135 Stratotanker during flight testing, a milestone the service says underscores the stealth bomber’s rapid maturation and advances its drive to field long-range strike capability at speed.

Service leaders cast the achievement as emblematic of a transformed acquisition approach centered on delivering integrated warfighting capability quickly, leveraging digital engineering and modern production practices. “The B-21 program is the leading edge of the acquisition mindset we are instilling across the force. Every test proves the success of empowering our leaders to deliver integrated capability from the start,” said Gen. Dale White. “The program’s use of digital engineering and modern production processes is delivering a mature, highly capable system, giving us confidence as we continue to smartly scale our production capacity at the speed of relevance.”

According to the Air Force, the B-21’s design emphasizes operational flexibility and fuel efficiency, reducing demand on theater tanker logistics and broadening options for combatant commanders. “The B-21’s fuel efficiency is one of the core components of its lethality” said Air Force Chief of Staff Gen. Ken Wilsbach. “This long-range strike bomber will reduce the demand on our tanker fleet and free up assets to support the joint force. This will provide a wider range of employment options and the deterrence our nation requires.”

The service described aerial refueling as fundamental to the bomber’s role in projecting power globally, assuring allies, and offering commanders flexible strike options. “For our bomber crews and the combatant commanders they support, this is about endurance and mission readiness,” said Gen. S.L. Davis, commander of Air Force Global Strike Command. “This capability ensures we can deliver penetrating long-range strike anywhere in the world, at any time. We are strengthening the capabilities of our bomber force and putting a highly effective and lethal weapon system into the hands of our warfighters.”

Aligned with the National Defense Strategy, the B-21 is built for high-end threat environments and is intended to carry both conventional and nuclear munitions as a visible, flexible element of the nuclear triad. Its open systems architecture is designed to speed integration of future capabilities as the threat landscape evolves, the Air Force said.

Test and evaluation at Edwards Air Force Base, California—conducted by the Air Force Test Center and the 412th Test Wing in partnership with Northrop Grumman—continue to reduce risk and mature the weapon system on the path to operational service, according to the service.
