Adams Air Force Base

 is a heavily fortified Enclave settlement outside the Capital Wasteland, available in the Broken Steel DLC pack for Fallout 3.

Adams AFB can only be accessed through the Presidential Metro and not before you have reached the appropriate point in the quest line. The base is a separate, new area outside of the Capital Wasteland. It appears to be as big as the locations from the previous DLC packs The Pitt and Operation: Anchorage.

Related quest: Who Dares Wins
During the Who Dares Wins quest the player is sent to wipe out the remaining Enclave soldiers in the Capitol Wasteland at Adams Air Force Base. The base contains a mass of Enclave soldiers, as well as standard defenses such as Sentry Bots and Automated Turrets.

Upon completion of the quest you will be able to return to Adams Air Force Base, which is then occupied by the Brotherhood of Steel.

Notable loot

 * 400 X Flamethrower Fuel - There is a holo-tape regarding flamer fuel that can be found in a hanger with research areas and walkways. The message says that the fuel is located due West of the Air Control Tower beneath a pile of tires and barrels (West-NorthWest Corner).
 * 2x Mini-Nuke in a corridor of the aircraft hanger with three derelict jet planes inside. One is Hidden under a desk, the other is hidden behind a filing cabinet.
 * Lots of Scrap Metal (30+ pieces).
 * Lots of medical supplies including Stimpaks and Blood Packs.
 * Enclave Soldier Log - located in the alley directly North of the rooftop where the Sector 2 Artillery Note is located. When in the alley and looking northward, turn left (west) and enter the opening between the walls. Follow the maze-like alley until you approach stairs with what looks like AC units on top.
