CTF (Combined Test Force) test pilots reported that the B-21 Raider is performing as expected, with the aircraft’s behavior closely mirroring the digital simulation. This alignment emphasizes the accuracy and reliability of the digital design environment used in the development of the B-21.

The B-21 Raider’s successful performance during these tests represents a critical step in a program that will demonstrate the aircraft’s capabilities and readiness as it moves toward operational status. The B-21 Raider is not just another aircraft, but a critical asset that is expected to play an important role in the future of the US strategic bomber capability, bolstering the nation’s defense posture with advanced stealth technology and next-generation avionics.

Development of the B-21 Raider officially began in 2015, when the US Air Force awarded Northrop Grumman a contract to design and build the next-generation bomber. The B-21 Raider is part of the Long Range Strike Bomber (LRS-B) program, which aims to replace the aging B-1 Lancer and B-2 Spirit bombers and augment the B-52 Stratofortress fleet. The program aims to enhance the US military’s long-range strike capabilities with advanced stealth technology and next-generation avionics.

From 2016 to 2019, Northrop Grumman focused on the initial design and development phases of the B-21 Raider. This period involved detailed designs and prototypes, while the Air Force maintained a high level of secrecy regarding the aircraft’s specific capabilities and design features.

In 2020, the US Air Force officially named the aircraft the B-21 Raider and released artist renderings, giving the public the first visual representation of the bomber’s general design. This exhibition marked an important step in the program.

As of 2024, the B-21 Raider is undergoing a rigorous flight test campaign at Edwards Air Force Base in California. Led by the Combined Test Force (CTF), which consists of Northrop Grumman and US Air Force personnel, the tests show the B-21 is performing as expected. Test pilots reported that the aircraft’s behavior closely matched digital simulations, underscoring the accuracy and reliability of the digital design environment used during development. Successful progress in these tests represents a critical step toward the aircraft’s operational readiness and eventual integration into the US strategic bomber fleet.

The B-21 Raider offers a number of advanced combat capabilities and state-of-the-art technologies that significantly enhance the US military’s strategic and tactical options. One of its key features is its advanced stealth technology, which makes it difficult for enemy radar systems to detect and track. This stealth capability allows the B-21 to penetrate advanced air defense systems and reach high-value targets with minimal risk of interception.

In terms of radius, the B-21 is designed for long-range missions, capable of flying long distances without refueling. This allows it to strike targets globally, providing a significant strategic advantage. In addition, the B-21 Raider boasts load flexibility, allowing it to carry a variety of munitions, including both conventional and nuclear weapons. This versatility allows the aircraft to perform a wide range of mission types, from precision strikes to strategic bombing.

The B-21 Raider is also equipped with the latest avionics and electronic warfare systems. These advanced systems enhance its survivability and effectiveness in contested environments by improving situational awareness, communications and defensive measures against enemy threats. In addition, the aircraft is designed with an adaptable, open architecture that allows for the integration of future technologies and upgrades, ensuring that combat capabilities remain at the forefront for decades to come.

Overall, the B-21 Raider represents a significant advance in bomber technology, offering unmatched stealth, range, payload flexibility and advanced avionics, making it a cornerstone of the US Air Force’s strategic and tactical operations.
