The US Air Force has confirmed that ground tests of the Northrop Grumman B-21 Raider, a heavy strategic bomber, have begun in Palmdele, California. These trials suggest that the first flight of a stealth prototype will take place at the end of this year.
After last month’s release of images showing ground tests of the B-21’s engine, rumors and unreliable images circulated on social media. However, on October 25, the US Air Force spokesperson confirmed to Aviation Week that the tests had indeed commenced. This confirmation was echoed by other defense news agencies.
“I can confirm that the B-21 is currently undertaking ground-based taxiing actions,” said the spokesperson. “Thorough testing is a crucial stage in the B-21 flight test program, enabling the evaluation of systems, components, and functionality. These tests help mitigate risks, optimize the design, and enhance operational efficiency.”
The Air Force plans to acquire a minimum of 100 B-21 bombers, with the first one expected to be operational by 2027. The B-21 is intended to augment the existing fleet comprising the B-1B Lancer, B-2 Spirit, and B-52J Stratofortress, ultimately replacing them by the 2050s.
