The public is reminded that scoping comments must be submitted no later than May 9, to be considered in the Draft Environmental Impact Statement (EIS) related the potential beddown of the Main Operating Base (MOB) 1 for the B-21 “Raider.”

The Department of Defense is developing a new bomber aircraft, the B-21 “Raider,” which will eventually replace existing B-1 and B-2 bomber aircraft. The Air Force eventually intends to procure at least 100 B-21 aircraft as part of three basing decisions, MOB 1, MOB 2 and MOB 3.

The Air Force is preparing this EIS to evaluate the potential beddown impacts of MOB 1 at Dyess Air Force Base, Texas or Ellsworth Air Force Base, South Dakota. MOB 2 and MOB 3 beddowns will be evaluated as part of a separate decision-making process in the future, following MOB 1.

The MOB 1 beddown will involve new facilities construction, B-21 flight operations and increases in personnel needed to support the mission.
All public scoping materials are available on the project website: For those without access to the website, a request may be made to mail a hardcopy package of scoping materials. This request may be submitted to Ellsworth and Dyess Public Affairs offices at the points of contact listed below.
