Northrop Grumman’s B-21 Raider stands as a product of over three decades of advancements in strike and stealth technology.

As the U.S. Air Force‘s next-generation strategic bomber, the B-21 Raider not only redefines air power but also marks a historic milestone as the world’s first sixth-generation aircraft to grace the skies.

Sixth Generation Technology

At the core of the B-21’s supremacy lies its adoption of sixth-generation technology. Externally, cutting-edge stealth and improvements in low observable processes make the aircraft more manageable and cost-effective to maintain.

Internally, the B-21’s open architecture facilitates rapid upgrades, from integrating new weapons to software enhancements, thanks to advanced networking capabilities and seamless cloud environment migration.

This innovation will likely ensure that the B-21 remains at the forefront of aerial defense into the coming decades.

A New Paradigm

The B-21 Raider program doesn’t just pioneer in technology but also reimagines traditional acquisition processes through a partnership-focused approach.

Northrop Grumman and the Air Force, in an exemplary collaboration, prioritize long-term shared success.

The commitment to transparency is evident in the industry-first data sharing agreement, granting end-users access to invaluable data, including the B-21 digital twin.

Positioned as the backbone of the future for U.S. air power, the B-21 Raider promises a new era of capability and flexibility.

Through advanced integration of data, sensors, and weapons, this aircraft can deliver both conventional and nuclear payloads, making it one of the most versatile and effective in the skies.

Its capacity to utilize a diverse array of stand-off and direct attack munitions solidifies its role as a pivotal asset.

Precision in Production

A strategic move in the B-21 Raider program was the construction of a production representative first test aircraft.

Unlike a prototype, this test aircraft is equipped with mission systems and built by the same manufacturing technicians using the same processes and tooling as production aircraft.

This approach ensures a smooth transition into production, laying the foundation for operational capability.

The B-21 as a Digital Aircraft

Embracing agile software development and digital engineering tools, Northrop Grumman mitigates production risks and enables modern sustainment practices for the B-21 program.

Ground testing has showcased the efficacy of digital modeling, surpassing industry standards and paving the way for next-gen platforms and systems.

Northrop Grumman’s investment in advanced manufacturing is evident in the digital ecosystem integrated throughout the B-21’s lifecycle.

From training and augmented reality tools for technicians to visualizing tasks, to streamlining integration of supplier parts, these advancements reduce risk, enhance efficiency, and foster expertise across the manufacturing workforce.

The National Team

Since the contract award in 2015, Northrop Grumman has assembled a nationwide team exceeding 8,000 personnel, including industry partners and Air Force members, along with 400 suppliers across 40 states.

This collaborative effort extends to the B-21 Combined Test Force, formed in 2019, comprised of Northrop Grumman and Air Force personnel conducting flight test operations before aircraft delivery.

Sustainment was a priority from the inception of the B-21 program. This proactive approach not only drives long-term efficiency but also yields immediate benefits, propelling the B-21 ahead in tech data, materiel readiness, and training.

The B-21’s Strategic Role

The B-21 Raider plays a pivotal role in supporting the US strategic deterrence strategy. Its advanced long-range precision strike capabilities empower Combatant Commanders to target any location globally.

This concept underpins a larger family of systems that deliver intelligence, surveillance, and reconnaissance, electronic attack, and multi-domain networking capabilities.

Honoring the Doolittle Raid

The B-21 Raider carries the legacy of the Doolittle Raid of World War II, a mission led by Lt. Col. James “Jimmy” Doolittle.

This historic event, undertaken by 80 airmen and 16 B-25 Mitchell medium bombers, marked a turning point in the war and serves as the inspiration behind the Raider name.

The pioneering spirit instilled across the workforce reflects the innovative journey of bringing the B-21 to life.
