Adams Air Force Base

 is a heavily fortified Enclave settlement outside the Capital Wasteland, available in the Broken Steel add-on for Fallout 3. The base 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 add-ons The Pitt and Operation: Anchorage. The location is based on Andrews Air Force Base.

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). The fuel is in a (Very Hard) locked crate.  The Enclave scientist with the holotape also carries the key to the stash.
 * 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. Climb up and you'll find a dead Enclave Soldier, a ripper, 2 psychos, a couple first aid boxes and the the holodisk.

Trivia
This location is based on the real-life Andrews Air Force Base and indeed, originally was to be named as such. Evidence of this can be seen in the game files, the architecture meshes are in a folder named andrewsbase.

Bugs/Exploits

 * An exploit for unlimited BoS armor, holotags, Enclave armor, ammo, and weapons (including the occasional BoS Paladin equipped with a Tesla Cannon) during the initial assault on Adams AFB. Just before you cross onto the runway after the deathclaw cages, BoS and Enclave troops are seen battling behind the blue pulse repulsion field. You can then cross onto the runway and either kill (bad karma) or wait for the Enclave to kill the BoS troops to collect their items. However, the fallen bodies disappear after about 10 seconds. The troops will respawn when you cross through the wrecked hangar back towards the deathclaw cages. This can be repeated to your heart's desire (or your carrying capacity). (Xbox 360)
 * Sometimes wrecked vertibird pieces hang in midair then drop out of the sky when approached (Xbox 360)
 * When using the artillery strike multiple times on the parked vertibirds several vertibirds may swoop down and gun your position with gattling lasers, missiles, and mini nuke carpet bombings.
 * Three sentry bots spawn between the Enclave mobile command crawler and Adams Storage Facility.
