The official presentation date of the B-21 Raider stealth bomber is already known.
Northrop Grumman, builder of the B-21 Raider stealth bomber, revealed in a tweet this morning that it will finally be unveiled in California on December 2.

The deployment will take place at the Northrop Grumman facility in Palmdale, California. The company said in September that six test bombers were in various stages of final assembly there.
However, the company and the Air Force have given few details about the launch. Northrop Grumman’s ad included a short video showing a B-21 wrapped in a holster illuminated by floodlights, and the date December 2.
The Air Force has not commented on the announcement.
This will be the first public unveiling of a new Air Force bomber in 34 years, since the debut of the B-2 Spirit in November 1988.

The first B-21 completed its initial ground tests in May, which included stress tests to verify the bomber’s structural integrity. Other tests and steps in the process that followed have included powering up the bomber, testing its subsystems, and applying coatings and paint.
The first flight of the B-21 will take place in 2023, a few months after launch. Northrop Grumman said in September that the timing of that flight “will be based on the results of ground tests.”
That B-21 will fly from Plant 42 in Palmdale to Edwards Air Force Base in California next year, where formal flight tests will take place.
Andrew Hunter, Under Secretary for Acquisition, Technology and Logistics for the Air Force, announced the rough schedule for the B-21 launch at the Air and Space Forces Association’s Air Space Cyber conference in September, saying he expected it in the first week. from December.
