Adams Air Force Base

 is a heavily fortified, Enclave settlement outside the Capital Wasteland which is accessible to the player via downloading the Broken Steel downloadable content for Fallout 3. The player will be guided there by map marker via the Presidential Metro located under the ruins of the White House after activating the Who Dares Wins quest line. The player will have the opportunity for the first time to ride a train in the game, as a train takes you to the air force base from the presidential metro. Adams Air Force Base is a separate, new area outside of the Capitol Wasteland. When looking at the map, it appears to be as big as the last two previous DLC locations for Fallout 3 (the Pitt and Operation Anchorage). NOTE: The player must complete the main quest before being able to access Adams Air Force Base, along with started the Broken Steel quest line.

Adams Air Force Base is the last remaining Enclave settlement left in Fallout 3 after the player destroys Raven Rock and defeats the Project Purity quest that ends the game. A point will come in the game (during the Who Dares Wins quest) where the player is sent to wipe out the remaining Enclave soldiers in the Capitol Wasteland at Adams Air Force Base. The base contains several new Enclave soldiers, including the devastating Enclave Hellfire Trooper, as well as standard defenses such as Sentry Bots and turrets.

Upon arrival to Adam's Air Force base, the player will be given the Tesla Cannon, a new powerful energy weapon (though it's considered to be a "Big Gun"), to clear out the remaining Enclave forces at the air force base. It is recommended that the player brings an adequate amount of supplies and weapons before wiping out the base, as there are at least 30 Enclave Soldiers to kill.

Vertibirds
For the first time in Fallout 3 the player will get the opportunity to ride a hijacked Vertibird at the end of the Broken Steel quest line when escaping from Adams Air Force Base. Players will also get the chance to blow up several Vertibirds with the new Tesla Cannon, which seems to be designed for this.

Appearances
appears in the Fallout 3 DLC Broken Steel.

Trivia
This location is based on the real-life Andrews Air Force Base and indeed, originally was to be named as such.

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 Stimpack and Blood Pack.

Adams Storage Facility (South-SE Corner of Runway)

 * Rapid-Torch Flamer - Around the corner on the right after entering, on a long table with assortment of weapons and goods.
 * Nuka-Cola Quantum - Same table.
 * 2 X Mini-Nuke - Same table.
 * 8 X Missile - 2 In locked ammo box on the right as you enter the building, other 6 on the table around the corner.
 * 28 X Abraxo Cleaner

Enclave Mobile Base

 * Alien Blaster - In the room where you encounter the sigma squad, you must first disable the barrier then lockpick the door, the Alien Blaster is inside a gun case which has a hard lock. This room is listed as the Armory. There are also approx. 100-200 Alien Power Cells in locked ammo boxes in the same room as the Alien Blaster (Only if you have the Scrounger Perk, If you don't it's more like 5-20). If you unlock the Hard gun case and it is empty, you can find the Alien Blaster on the Armory Master's body outside the armory, or it may be on the body of a scientist. (This editor found only 26 Alien Power Cells in the locked ammo boxes in the armory and 11 on the Armory Master's body. Presumably, the Armory Master used up some of the ammo.) You should get your original Blaster repaired to the extent possible (which may only be about 50%) before using this one to repair it yourself beyond that (which may or may not be preferable to keeping both at 50%).


 * Directions To Armory: When you first enter the Launch Platform Base, there is an Armory sign in the Northeast corner. This is not the one. Instead, (1) go to the door at the South end of the room. (2) Go up the ladder and turn West (left) as far as you can and then North to some stairs. (3) Go up the stairs, turn right, and through the door marked "High Security Clearance." (3) Go across the room and through the door marked "Robotic Defensive Control Center" and under the sign "Mainframe". (4) There are two consoles: one to deactivate robots and one to unlock doors. Use both. (5) Turn around and exit the mainframe, turn left and go down the stairs. (6) Turn right, go through the "Deathclaws" door, down the hall to a door on the left. (7) The Armory is across that room.


 * The Armory and/or the Armory Master's body have a wealth of weapons (all in prime condition) and ammo in addition to the Alien Blaster. The priciest may be a Precision Gatling Laser with a Value of 2145 despite only having a DAM of 109 compared to a Value/DAM of 1463/112 for a regular Gatling Laser and 1756/153 for the Vengeance Gatling laser -- all at about the same level of repair. (Now all you have to do is find a merchant with 2145 caps.) You may also come across a scientist whose lab coat is valued at a whopping 150 caps, despite not having any obvious special properties beyond the usual +5 Science.


 * Once you've completed Who Dares Wins the mobile base is no longer accessible from outside (the ramp providing entry is destroyed by the orbital strike) so make sure you pick up anything that you would like later, such as anything mentioned above.
