Our investments in manufacturing capacity are accelerating production, providing flexibility to support future fleet growth and ensuring long-term U.S. Air Force strike dominance.
These investments power our digital ecosystem, equipping the B-21 Raider with highly advanced software, manufacturing and engineering tools. As a result, software certification time has already been reduced by 50%, ensuring the B-21 stays at the speed of relevance for future technology insertion. The ecosystem also enables real-time validation of aircraft performance during tests.
5. Delivering Results that Ensure America Wins
Northrop Grumman’s expertise in advanced aircraft systems is driving flight test results that showcase speed, efficiency and exceptional performance.
Multiple B-21 Raider aircraft are currently in flight test, consistently exceeding expectations. Most sorties achieve “code one” status, indicating the aircraft returned from its flight without maintenance issues and is ready to go fly again. This reaffirms the quality of the design and build, and signals strong future operational performance.
Simultaneously, Northrop Grumman engineers are conducting ground tests to ensure the B-21 can operate in the most extreme mission conditions. These test results consistently surpass digital modeling predictions, further validating the aircraft’s design and capabilities.
6. Accelerating Advanced Manufacturing
Northrop Grumman’s advanced manufacturing processes, including digital and augmented reality tools, enable technicians to visualize tasks and solve problems before ever touching the plane. This approach connects technicians to design engineers as never before, improving efficiency and cultivating expertise throughout the manufacturing workforce.
Northrop Grumman has invested in manufacturing technology and capacity at our facilities across the U.S. to accelerate and scale production of the B-21 Raider. We are increasing production rates on capability that will project American power anywhere in the world.
7. More than a Bomber
As the world’s most advanced aircraft to take the skies, the B-21 Raider combines unmatched range, access and payload in a single system designed to perform specialized missions no other aircraft can accomplish.
Instrumental in maintaining U.S. and allied security amid a complex global landscape, the B-21 is a key part of a powerful family of systems. It delivers a new era of capability and flexibility by seamlessly integrating data, sensors and weapons – enabling precision strikes and comprehensive situational awareness.
8. Ready on Day One
Northrop Grumman is developing comprehensive training, sustainment and fleet management tools for the Air Force as they prepare to operate and maintain the B-21 Raider. Leveraging extensive flight test data and decades of sustainment experience across a variety of systems, these tools ensure the B-21 enters service ready, affordable and sustainable at scale.
Test pilots report exceptional handling during aerial refueling, noting a high degree of stability and control. These qualities reduce training requirements and enable faster refueling, increasing operational tempo and agility – further proving that the B-21 will deliver unmatched performance for U.S. Air Force operators.
9. American Made Deterrence
An all-American team of more than 8,000 industry and Air Force personnel are designing, building, testing and delivering on the promise of B-21. The team consists of more than 400 suppliers across 40 states. This is a nationwide effort to provide deterrence capability that strengthens and defends our nation.
10. Bold, Innovative, Courageous
The B-21 Raider is named in honor of the Doolittle Raid of World War II when 80 airmen, led by Lt. Col. James “Jimmy” Doolittle, and 16 B-25 Mitchell medium bombers set off on a mission that changed the course of World War II. The raid was a catalyst for a multitude of future progress in U.S. air superiority and serves as the inspiration behind the Raider name and the pioneering, innovative spirit instilled across the workforce bringing the B-21 to life.
