The doors to the Bomb Storage (Warhead Storage) are both locked (Very Hard), but the Bomb Storage basement can be alternatively accessed through an underground path in the cellar of the CO Quarters. Unfortunately, the Fort Constantine Bunker Door can only be opened with Ted Strayer's Special Key and cannot be lockpicked. Also, the only access to the T-51b Power Armor is through this pathway, as you can't open the door from the other side in the Bomb Storage, because Tara holds the key. However, the cellar grants access to the Launch Control Bunker, eventually leading to basement of the Bomb Storage. The door to the Bomb Storage requires Dukov's Special Key. In here is Tara's corpse, (which holds the Warhead Storage Key), two Very Hard locked doors, and a door (can only be accessed with Dave's Special Key) on the opposite side which finally leads to a room with the T-51b Power Armor.
