The B-21 Raider will be a dual-capable penetrating strike stealth bomber capable of delivering both conventional and nuclear munitions. The B-21 will form the backbone of the future Air Force bomber force, consisting of B-21s and B-52s.

Designed to operate in tomorrow’s high-end threat environment, the B-21 will play a critical role in ensuring America’s enduring airpower capability.

The B-21 Raider will be a component of a “larger family of systems” known as the Collaborative Combat Aircraft (CCA). NGAD, for example, includes a crewed platform, uncrewed aircraft (CCAs) that operate as loyal wingmen, sensors, weapons, and more, all working together to create a powerful air combat capability for a conventional long-range strike, including Intelligence, Surveillance, and Reconnaissance, electronic attack, communication, and other capabilities. It will be nuclear-capable and designed to accommodate manned or unmanned operations.

Additionally, it will be able to employ a broad mix of stand-off and direct-attack munitions.

The B-21 is being designed with an open systems architecture to reduce integration risk and enable competition for future modernization efforts, allowing the aircraft to evolve as the threat environment changes.

Many have speculated that the B-21 Raider is just a B-2.1. That isn’t true. Northrop Grumman, which builds the B-21, stated at its rollout that the B-21 is “the most advanced stealth aircraft ever built.”

The Raider is smaller, with a wing span about 22 feet shorter; its intakes are much more slender, leading to better stealth. The keel of the aircraft is broader and more deep, indicating larger weapons bays. The lines are smoother, which helps with stealth, and the color is a lighter gray color. But as industry analysts have heard, the most significant changes are on the inside.

Here are Eight Key Facts you need to know about the B-21 Raider stealth bomber.

Sixth-Generation Aircraft

The B-21 Raider program is on track and continues flight testing at Northrop Grumman’s Edwards Air Force Base manufacturing facility, California. The B-21 will have an open architecture to integrate new technologies and respond to future threats across the spectrum of operations.

The B-21 is a sixth-generation aircraft, meaning it leverages the latest advancements in stealth technology and low-observable processes, making it easier to maintain and less costly than previous systems.

Stealth Technology

The B-21’s design incorporates next-generation stealth capabilities to evade air defenses. The Raider incorporates cutting-edge stealth technology, including advanced materials and contouring, to significantly reduce its radar cross-section compared to the B-2.

Its unique flying wing design, incorporating radar-absorbing materials (RAM) and aerodynamic enhancements, also minimizes its thermal and radar signatures. The B-21’s air intakes are much more slender, designed to reduce radar reflections, and are integrated with the wing structure.

Digital and Open Architecture

The B-21 features a digital, open architecture that will enable rapid upgradability, from the inclusion of new weapons to software upgrades, thanks to advanced networking capabilities and a successful cloud environment migration.

Nuclear and Conventional Capabilities

The B-21 can deliver both nuclear and conventional munitions. For nuclear deterrence, it can deploy B61 and B83 gravity bombs as well as the Long Range Stand-Off (LRSO) nuclear cruise missile.

Long Range and Survivability

The B-21 is designed with a focus on long-range and survivability, enabling it to strike targets anywhere in the world. The Raider is intended for long-range operations, with a stated range of 2,500 miles without refueling.

This stealth design enables the B-21 to evade enemy detection and penetrate sophisticated air defenses. It is designed to be a “penetrable” strike platform, meaning it can operate in contested airspaces.

Ease of Maintenance

The B-21 is designed for easy maintenance, with a focus on achieving high readiness rates. Although the cost per flight hour is not known, it is expected to be less than the B-2’s cost of $110,00 per flight hour.

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.

After the attack on Pearl Harbor, morale in the US was low. Four months later, Doolittle’s Raiders bombed Tokyo and other industrial cities.

The actions of these 80 volunteers were instrumental in shifting momentum in the Pacific theater. This marked the raid as the beginning of future progress in US air superiority from land or sea. The courageous spirit of the Doolittle Raiders is the inspiration behind the name of the B-21 Raider.
