First look at America's costly stealth bomber in flight

The B-21 Raider is a stealth bomber that utilizes advanced technology that makes it difficult to detect with current observation and survey methods.

In January 2024, representatives of Northrop Grumman confirmed that mass production of the B-21 Raider had begun. The estimated cost of a single unit, including spare parts and auxiliary equipment, can reach up to $700 million.

Although the aircraft had been shown before, it had never been seen in flight until now. This changed with photos published by the 412th Test Wing of Edwards Air Force Base. A brief description indicates that the picture of the taking-off B-21 Raider was taken in January, and the photos of the bomber in flight and in the hangar were taken in early April.

Powered by two Pratt & Whitney engines, the B-21 Raider is expected to reach up to 620 mph speeds. It is designed to operate at altitudes of up to 49,000 feet and has a range of 6,835 miles.

Stealth technology and the ability to cover great distances are complemented by the aircraft's readiness to carry various types of armament. The B-21 Raider is designed to carry not only conventional weapons but also a nuclear arsenal. This capability allows it to be part of the American nuclear triad, which comprises air, land, and sea components.

"We are in the midst of the flight testing program, which is proceeding correctly. We are fulfilling the purpose these programs are designed for, allowing us to learn the unique characteristics of this platform in a very effective way," said Andrew Hunter, Assistant Secretary of the Air Force for Acquisition, Technology, and Logistics, to a Senate Armed Services Committee on May 8.

Ultimately, the United States Air Force intends to have as many as 100 B-21 Raiders. They will replace the aging fleet of B-1B Lancer and B-2 Spirit bombers.
