SUPPORTED BY THE RECORD

What we know

The Air Force reported combined developmental and operational test participation in June and a future Ellsworth arrival target in July.
An official September record documents the activation of a dedicated B-21 integration unit at Ellsworth.
Test participation, organizational preparation and a base-arrival target are distinct from a service-entry declaration.

STILL OPEN

What we don’t know

The full test results and acceptance criteria are not established by these public releases.
A completed operational service-entry milestone is not established by the reviewed record.
This selected-source review cannot establish that no later schedule changes or announcements exist.

Scope of this record

Selected official evidence through a 28th Bomb Wing record posted on 14 September 2026, documenting the integration unit activation on 9 September. This is preparation for receiving the aircraft, not evidence of operational service entry. Reviewed 4 October 2026; this is not continuous monitoring.
