Summary: Northrop Grumman's development of the B-21 Raider is a critical component of the U.S. Air Force's strategy to maintain aerial dominance, especially as China progresses with its H-20 bomber.

-The B-21 Raider, expected to feature advanced stealth capabilities and a wingspan about 15% shorter than its predecessors, is designed for long-range, intercontinental missions including intelligence collection and battle management. This next-generation bomber will also incorporate modular systems for future technological upgrades. However, with budgetary constraints and potential production challenges, there are concerns about the Raider's timeline and eventual deployment.

-The urgency to field the B-21 is accentuated by the aging U.S. bomber fleet, consisting of B-2s, B-52s, and soon-to-retire B-1s, which may not sufficiently compete with a new Chinese stealth bomber. The successful deployment of the B-21 is deemed essential to ensure the U.S. retains its competitive edge in aerial warfare capabilities.

The B-21 Raider: America's Answer to China's Advancing Bomber Technology

China is working to develop its next-generation long-range bomber. The H-20, when it arrives, could end U.S. dominance in the category. 

By the end of the Second World War, the U.S. was producing a great number of airframes. In 1944, annual output was more than 96,000 units. Although most of these airframes were fighters, a substantial fleet of bombers was also introduced. Roughly 13,000 B-17 Flying Fortresses, 18,000 B-24 Liberators, 10,000 B-25 Mitchells and 4,000 B-29 Superfortresses were developed.

These numbers have dropped dramatically over time, however, and the U.S. has not developed a new bomber in more than 20 years.

As China makes progress on its H-20 bomber, U.S. engineers are racing to ensure the next-generation B-21 Raider makes it to the production line first. The Northrop Grumman stealth bomber is designed to operate as a long-range, intercontinental strategic bomber for the U.S. Air Force. 

When the Raider enters service, it is expected to carry out a number of roles, including intelligence collection and battle management. Many details surrounding the new bomber remain highly classified, but Northrop has revealed some information. The Raider’s wingspan will likely be approximately 15% shorter than its predecessors, a significant advantage that will make the new aircraft more challenging for enemy radar to detect.

The B-21 will incorporate modular systems that will enable future upgrades as new technologies emerge – similar to the F-35 Lightning II fighter platform. 

What if the B-21 Raider Program Is Canceled?

While the introduction of a next-generation bomber appears paramount considering China’s progress on the H-20, budgetary constraints and a smaller planned output of Raiders have some analysts worried that the program could be nixed altogether.

Without the B-21, the Air Force would have to rely on its existing, rapidly aging bombers. The service received a mere twenty-one B-2 stealth bombers following the collapse of the Cold War, less than one-sixth of the anticipated number.

This platform, although still formidable, is no longer as stealthy or capable of deep penetration operations as it was when it was first introduced to service. Seventy-six B-52 bombers also remain in service today and are expected to continue to fly until the 2050s thanks to upgrades. The Air Force also possesses a fleet of B-1 bombers, although the remaining aircraft in this series are expected to retire as the Raider is developed.

The Air Force would still possess a solid fleet of bombers if the Raider program were canceled. However, these airframes might not outmatch a next-generation Chinese stealth bomber. Beijing has yet to release much information surrounding its H-20 program, and any specs it claims right now could be exaggerations.

Nevertheless, the timely introduction of the B-21 Raider bomber should be a priority for the service and defense officials.
