Benefiting from more than three decades of strike and stealth technology innovation, the B-21 stealth bomber is the next evolution of the US Air Force (USAF) strategic bomber fleet and the first sixth-generation aircraft to reach the skies.

The B-21 Raider continues its flight test campaign at Edwards Air Force Base, California, led by a Combined Test Force (CTF) comprised of Northrop Grumman and Air Force personnel. CTF pilots indicate the jet is performing as expected with the aircraft flying like the simulator, reflecting the precision of the digital environment on B-21.

Here is what you need to know about the Northrop Grumman B-21 Raider as it continues flight test.

Sixth generation

The B-21 Raider is setting standards for sixth-generation technology. On the outside, next-gen stealth and advancements in low observable processes will make the aircraft easier and less costly to maintain than prior systems. Inside, the B-21’s open architecture will enable rapid upgradability from inclusion of new weapons to software upgrades thanks to advanced networking capabilities and successful cloud environment migration.

Production focus

A key strategy of the program was to build a production representative first test aircraft. Rather than a prototype, the B-21 test aircraft is equipped with mission systems and was built by the same manufacturing technicians using the same processes and tooling for production aircraft. The body of knowledge and experience gleaned in the development process supports a smooth transition into production on the path to delivering operational capability.

A digital aircraft

Northrop Grumman uses agile software development and digital engineering tools to mitigate production risk and enable modern sustainment practices for the B-21 program. Ground testing demonstrated the efficacy of digital modeling with results that outperformed industry standards, paving the way for next-gen platforms and systems.

Advanced manufacturing

By embracing the benefits of advanced manufacturing, Northrop Grumman invested in a digital ecosystem for the B-21 throughout the aircraft’s lifecycle. From training and augmented reality tools allowing technicians to visualize tasks and solve problems before ever touching the plane, to easing integration of supplier parts on the aircraft, these advancements have reduced risk, supported efficiency and cultivated expertise throughout the manufacturing workforce.

Sustainment at the forefront

Sustainment was a programme priority throughout the B-21 program’s design phase. In addition to driving efficiency over the long term, this approach yields more near-term benefits and sets the B-21 further along on tech data, materiel readiness and training which will benefit the user community upon fielding.
