People of the Commonwealth. Do not interfere. Our intentions are peaceful. We are the Brotherhood of Steel.

The Prydwen is a modified and armored Brotherhood of Steel airship that flies throughout the skies of the Commonwealth. The vessel serves multiple roles for the Brotherhood, including those of aircraft carrier, command center, clinic, personnel quarters, equipment maintenance bay and research facility. It is, for all intents and purposes, an airborne military base. It is currently moored to the Air Traffic Control Tower at Boston Airport.


The Prydwen was constructed at Adams Air Force Base over a period of six years. It took an initial two years to collect the materials necessary and another four to actually construct the airship, and by 2287 had been in service for five years.[1] It weighs forty thousand tons, as noted by Lancer-Captain Kells and Elder Maxson. The nuclear core was taken from an old aircraft carrier as the previous one was not sufficient to efficiently power all the systems.

The airship is filled with hydrogen, as stated during the quest Airship Down. Four pylons attached to the ship's flight deck carry a single jet engine each, being responsible for controlling the Prydwen's altitude and help to keep the ship aloft. There are four docking hooks for Brotherhood modified VB-02 Vertibird gunships attached to the airship's hull. Vertibirds are accessible via the flight deck. Due to the combustible nature of hydrogen, the ship itself is not capable of combat, and this is stated by the crew.


The Prydwen is divided into two exterior areas and two indoor areas: the flight deck, the command deck, the main deck, and the forecastle.

On the main deck is a medical bay, mess hall, power armor station, crafting equipment and a shop (at the end of the corridor). There are also stairs that lead either up to the living quarters or down to a storage area. Around the perimeter and along the top are patrolled catwalks. The main deck is contained within the airbag, as the hydrogen is inside several canisters positioned around the outer hull.

The flight deck is located along the midsection of the gondola. There is a control room/storage area overlooking the deck, accessible at the back of the flight deck.

The command deck has three levels. The top level has Maxson's observation deck. The next one down is a storage area, with access to the forecastle. Finally, the bridge is at the bottom, where Lancer-Captain Kells can be found.

The forecastle is a small balcony which is accessible from the top the command deck.

Related quests


  • The Prydwen will show up right after the main quest Reunions is finished, flying in over the western mountain range of the map and making its way across the Commonwealth, until it finally anchors above the Boston Airport. After this, the Sole Survivor can visit it during the Brotherhood of Steel quest Shadow of Steel offered by Paladin Danse.
  • Its remains can be visited if destroyed, and respawning Brotherhood corpses can be found and looted. Brotherhood of Steel scribes, knights, and paladins may appear and attack the Sole Survivor.
  • Bringing certain companions onto the Prydwen will cause different reactions from the Brotherhood personnel.
    • Bringing Nick aboard will cause a generic Brotherhood member to exclaim that "machines shouldn't have free will," leading Nick to rhetorically ask if he believes that because he gave up his a long time ago. Another scenario is a generic Brotherhood member will state that Nick "disgusts" them, and Nick will retort that "the feeling's mutual."
    • Bringing Hancock aboard will cause a member to ask the Sole Survivor if "that thing" is "tame," which causes Hancock to chuckle and mumble "hardly."
    • Bringing Strong aboard causes a member to shout "mutie aboard," and Strong will say he is being too loud and he wants to throw him off the bow.
    • Bringing X6-88 aboard causes a member to observe that something is "off" about the Sole Survivor's "pal," and X6-88 will state his synth designation, status as a courser, and casually state the fact that he could easily kill all personnel aboard without a second thought.
    • Bringing Dogmeat aboard causes some members to compliment him by saying that he is a tough looking dog, or insult him.
  • When pickpocketed, most items will respawn periodically. This includes Airship captain's hat.

Behind the scenes

  • Prydwen (Middle Welsh lit. "fair-faced", "handsome") is the name of King Arthur's ship in the native Welsh literature concerning the legendary character. Arthur and his men board it to sail to the Otherworldly fortress of Annwn [pronounced; ah-noon] in the somewhat cryptic poem Preiddeu Annwfn [pronounced; Prey-they--Ann-oovn] as well as when they sail to and from Ireland in the prose text Culhwch ac Olwen in an attempt to gain a magical cauldron. It is not explicitly named in any other native Arthurian tale or poem, and in the Anglo-Norman literature that drew from it Arthur does not appear to have a comparable vessel.
  • It is pronounced by multiple characters different ways. Military Frequency AF95 broadcasts pronounce it 'preed-win' whereas Paladin Danse pronounces it 'prid-win'; the Welsh pronunciation is 'PRUHD-wehn'.


  • PCIcon pc Stealing from the Prydwen armory can result in all Brotherhood NPCs turning hostile against the Sole Survivor. This can happen regardless of whether the Survivor is detected or not and can happen even if a Stealth Boy is used. Solutions include picking up the desired item and moving it outside the armory before stealing it. This does not alert the Brotherhood.[verified]
    • This only happens if a very significant amount of loot is stolen. [verified]
  • PCIcon pc In some cases after entering the Prydwen you will fall through the floor. Loading a previous save may fix this issue.[verification overdue]
  • PCIcon pc Killing the Brotherhood lancer-sergeant on the northern Vertibird gantry may result, after a save and reload, in an invisible corpse with an untargetable version of the NPC standing over it. The invisible corpse may be looted, and may even be moved, but will revert to its original position on reload. No known fix, but ultimately harmless. This bug has also been seen on the scribes along the flight deck.[verified]
  • PCIcon pc Following completion of the quest Airship Down, the Prydwen will still appear as a fast travel destination in the Pip-Boy. Attempting to fast travel to the Prydwen will yield the message "Fast Travel is currently unavailable from this location" regardless of where attempted.[verification overdue]
  • Xbox OneIcon xboxone Fast traveling to the Prydwen causes automatron companions to disappear. Afterwards, all automatrons will fail to fast travel and no longer appear. [verification overdue]
  • PCIcon pc Stealing the patrolling sentries' power armor and storing the suits in a settlement may lead to those sentries reappearing inside their suits in that settlement later, even if the armor's ownership was transferred to the player via console commands.[verification overdue]
