Sentinel site

Sentinel Site Prescott,Captain Dunleavy's holotape simply called Sentinel Site in the game, is a location in the Glowing Sea region of the Commonwealth in 2287.
The facility is one of the few places in the Glowing Sea hardened against radiation, so the player character can safely remove radiation protection gear while inside.
==Background==
A pyramid structure surrounded by irradiated sludge, Sentinel Site Prescott was officially a nuclear munitions disposal facility.Danse: """"(Danse's dialogue) However, in reality, it was a missile silo that stockpiled Mark 28 nuclear warheads for the U.S. military, and performed experiments focused on combining them with existing ballistic missiles.Sentinel site terminal entries; terminal, Pod Alpha - Launch Report
With a seemingly inexhaustible stock of these warheads,Sentinel site terminal entries; terminal, Pod Beta - Launch Report the facility performed at least 23 test launches, with one final, actual launch performed on the eve of the Great War. However, the launch failed to register with the system, locking the hapless staff inside and dooming them to death from thirst and starvation. Many were turned into feral ghouls, sealed beneath the ground.Fallout 4 Vault Dweller's Survival Guide Collector's Edition pp. 364-365: "[5.31] SENTINEL SITEThis secret military installation has a stockpile of potent Mark 28 nuclear warheads, many of them still intact. An ominous pyramid surrounded by irradiated sludge, this location was in the middle of launching a missile strike when the bombs dropped. It is now a tomb for ferals."(Fallout 4 Vault Dweller's Survival Guide Map) Captain Dunleavy of the 132nd Engineering Corps recorded the crew's final moments before the first bombs hit the Commonwealth.
By 2281, the site had been infiltrated by the Children of Atom, who were able to activate the launch sequence before being massacred by the feral ghoul inhabitants. Although no missile was present on the launch pad, all blast doors in the facility were closed and locked, requiring the Sole Survivor to deactivate the sequence or access certain terminals in order to gain full access to the facility. The Brotherhood of Steel then followed, seeking to provide Liberty Prime with a new supply of nuclear weapons from the site.Liberty Reprimed
==Layout==
The exterior of the main bunker is a concrete pyramid, with a blast door entrance on the northeast side; four separate ventilation towers also rise to the northeast. Through the entrance is a large room resembling a missile silo featuring a network of catwalks. Descending the catwalk to the left leads to the first control room. On a desk on the room's lower level is the sentinel site blast door override holotape, which will open the blast doors in the facility when loaded in the doors' related terminals. The blast door near the desk opens to reveal a small observation room, where a terminal may be accessed for a pre-War launch report. Continuing down the catwalk, a second similar observation room and terminal are in the control room on the next level down. Finally, a terminal that may be used to abort the launch sequence is on the lowest level. The nearby elevator may be used to return to the catwalk by the entrance on the top level.
At ground level, the northeast section of the main silo area features three unused nuclear warheads in metal crates and a fourth on a megaloader. They will not detonate from gunfire or explosions, but be prepared for a few mole rats, as well as a horde of feral ghouls in a tunnel nearby to the southeast. Two barracks rooms with bunk beds are along the southeast side of the middle of the tunnel. At the end of the tunnel, a pair of blast doors are ahead, while a button to call a cargo elevator is to the right. The elevator platform hosts a leveled glowing one and a steamer trunk. The elevator ascends to an exit in one of the exterior ventilation towers.
Up the short set of stairs to the left of the blast doors is a control room containing Brother Henri and Atom's Wrath if Liberty Reprimed is active. The terminal in this room requires Henri's password to access, and may be used to open the blast doors to the bomb storage area, an expansive room filled with nuclear warheads. The room contains moderate to severe radiation, peaking at 28 rads per second near the back.

==Notes==
* If wearing a suit of power armor equipped with a jet pack, do not attempt to jump up through the hatch in the elevator; doing so will cause the player character to clip into a pile of debris and become trapped.
* If the quest Liberty Reprimed has not yet started, the room where the Mark 28 nukes are stored will not be accessible; there will be a shelf blocking the door.
* When at this location, companions make comments, which are activated at four locations: the exterior entrance, the gantry just inside the main entrance, the warhead storage room entrance, and a fourth location.

==Appearances==
The Sentinel site appears only in Fallout 4.
==Behind the scenes==
The original Sentinel Program was designed to place nuclear-tipped interceptor missiles in the suburbs around major cities, protecting them from incoming ballistic threats. The project was scrapped due to public backlash, but one site was partially constructed near Sharpner's Pond in North Andover, MA.
