|“||People of the Commonwealth. Do not interfere. Our intentions are peaceful. We are the Brotherhood of Steel.||”|
—The Prydwen arriving in the Commonwealth
普利德溫號 是一艘特化程度极高的装甲飞艇，它是钢铁兄弟会在聯邦的核心，扮演着包括空中母舰、指挥中心、医院、兵营、装备维护中心和科研中心在内的多重角色。It will be moored to the air traffic control tower at Boston Airport shortly after the Sole Survivor exits Fort Hagen during Reunions.
据飞艇的舰长凯斯and Elder Maxson所言，这艘飞艇的总重量高达四万吨之巨. Before the journey to the Commonwealth, 它使用的反应堆被一台从战前旧航空母舰中回收的更新型的反应堆取代。
艇内充满了氢气，as stated during the quest Airship Down。同时还要仰仗四台升力发动机才能让飞艇浮空並飞行。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 氢气, 这条飞艇并不适合投入战斗, and this is stated by the crew.
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.
主甲板在巨大的氢气气囊的下方, as the hydrogen is inside several canisters positioned around the outer hull.
飞行甲板位于普莱德文号飞艇的腹部，There is a control room/storage area overlooking the deck, accessible at the back of the flight deck.
指挥甲板有三层，上层甲板 has Maxson's observation deck. The next one down is a storage area, with access to the forecastle. 而下层则是舰长凯斯的所在地。 艇首甲板位于整个飞艇的最前端，是视野最为开阔之处，which is accessible from the top the command deck.

- Rockets' Red Glare - The Sole Survivor, Deacon and Tinker Tom lead a secret raid to destroy the Prydwen.
- With Our Powers Combined - The Brotherhood have caused enough trouble, lead the Minutemen to destroy the Prydwen.
- 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.
- If the Sole Survivor has not yet dealt with the Brotherhood of Steel right after the Prydwen shows up (by avoiding the Cambridge Police Station), the optional Brotherhood quest Reveille begins, where it is only referenced as "the Brotherhood of Steel airship."
- 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 the airship captain's hat.
- The two suits of T-60 power armor at the power armor stations can be accessed via the power armor workstation, therefore be upgraded and looted without stealing if one were to unequip them.
- 普利德溫號 (中古威爾斯語 lit. "fair-faced," "handsome") 是關於威爾斯文學作品的傳奇人物亞瑟王的船艦名稱。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 "prud-when."
- 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.[已核实]
- This only happens if a very significant amount of loot is stolen. [已核实]
- 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.[已核实]
- 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.[已核实]
- Reunions, the Prydwen may not be seen in the sky and Military frequency AF95 may not play. This can be fixed using the console command setstage 2bf21 1 This will teleport you to the roof of the Cambridge Police Station and tell you to board the Vertibird.[verification overdue] After killing Kellogg in the quest
- Arthur Maxson's dialogue: "Proctor Ingram's managed to keep a 40,000 ton airship aloft for the past five years. I'd say that earns her the benefit of a doubt."
