Detailed walkthroughEdit

Meet Elder Maxson on the flight deck for the Sole Survivor's first assignment as a Brotherhood Knight after becoming familiar with the Prydwen and the crew.

Maxson's orders are to travel to Fort Strong, exterminate the super mutant forces and secure the armory, which will give the Brotherhood an advantage in the upcoming war.

Step onto the Vertibird and man the mounted minigun. After a short trip, the aircraft circles the area while the player character uses the minigun to kill the super mutant behemoth (and any remaining super mutants after the Vertibird lands).

Disembark and remove all indicated super mutants. Next, enter the armory and wipe out all hostiles on every floor of the building.

Talk to Paladin Danse, who decides to stay and make sure the armory is secure (you can however ask him to join you by just interacting with him again on the spot). One can also pass a medium speech check and ask why he hates super mutants so much.

Return to the Prydwen and speak to Maxson for a reward of Vertibird signal grenades.

  • Both Nick Valentine and Hancock like the Sole Survivor accepting the quest and comment on it.
  • The Vertibird can be shot down by the super mutants or other sources. The quest can still be continued by traveling to Fort Strong by foot.
  • Make sure to search the area for loot. There is a U.S. Covert Operations Manual and a mini nuke behind a novice locked door, and there are at least 2 other mini nukes around Fort Strong.
  • If Danse is the player character's active companion during this quest, he is automatically dismissed once the armory is secured and will return to his current home location (the Prydwen by default). He can be re-recruited once the quest is completed.
  • If the Sole Survivor skips the speech check and instead outright agrees with Danse, they will earn his respect and raise their relationship level.
  • If Danse's relationship level has already been raised to the point where he shares his history, no speech check will be available. Instead, there will be a dialogue option that refers to said history.
  • Danse loves it if the player character agrees with him that super mutants should be eliminated; Cait likes it. If the player character disagrees, Danse hates it and Cait dislikes it. Other companions may also react to this decision.
  • Cait likes it when the player character talks to Maxson to finish the quest, no matter where the discussion leads.
  • The option to purchase Vertibird signal grenades from Proctor Teagan is unlocked after the completion of this quest.
  • Upon completion of the quest, the stash of mini-nukes can be found on the Prydwen just below Proctor Teagan. There are three mini nukes available to the player character.


  • ps4Icon ps4 It is possible that the player character may be unable to board the quest designated Vertibird. Interacting with it causes nothing to happen in such cases. Travelling to Fort Strong by foot will update the quest. Entering the Prydwen and coming out again may fix this.[verified]
  • pcIcon pc Sometimes the Vertibird is not in its bay, and the quest marker points to the other Vertibird (which takes you to the airport). The quest Vertibird can be found landed on the beach below the Prydwen and can be boarded there.
  • pcIcon pc Companions, particularly Paladin Danse, may fail to board the Vertibird if the player enters first. To remedy this, it is advisable to order the companion to board the Vertibird first.[verification overdue]
  • pcIcon pc ps4Icon ps4 After getting the quest and talking with Elder Maxson, the marked Vertibird to take the player character to Fort Strong does not appear. If one quits and reload, it will appear but won't allow the Sole Survivor to enter. One may need to take the Vertibird on the opposite side down to the ground underneath and then back up to the flight deck to hopefully be able to use the marked Vertibird. Saving and reloading does not resolve the issue.
    • This can be resolved on the PC using the console: open the console, click on the Vertibird and type activate player. Loading a save from before exiting The Prydwen can fix this issue on PS4. [verification overdue]
  • ps4Icon ps4 If foregoing the Vertibird because it is not allowing the player character to enter, one can go on foot to take Fort Strong and complete the quest.[verified] However, if the player character has a companion, the companion will remain on the airship flight deck and one can no longer talk to them. Swapping out companions will always result in the new companion leaving (wherever they are) and appearing back on the airship flight deck. Quitting and reloading does not work. To resolve, summon a Vertibird using a grenade obtained from Maxson and enter. After landing, the companion should be with the Sole Survivor again. Waiting in the command deck sometimes fixes the issue.[verification overdue]
  • Another bug happens when the player character has cleared out the Fort Strong Armory. The next objective is to speak to Paladin Danse. When the player character engages Paladin Danse, he immediately attacks and he will take no damage. If the player character fast travels to the Prydwen, the BOS will also attack the player character instantly.[verification overdue][platforms tag needed]
  • pcIcon pc xboxoneIcon xboxone Trying to shoot while on the Vertibird doesn't work. The bug actually occurs a bit earlier (not able to display/shoot with weapon) by recruiting Paladin Danse as the partner. Using the text dialogue to go alone usually fixes this bug.[verification overdue]
  • pcIcon pc After clearing the first section of the Armory, the V.A.N.S. Perk and the quest marker tell to go outside. Exiting Fort Strong Armory and returning to turn the quest in will not work. One must enter the elevator car in the East corridor to proceed to the larger testing area to finish clearing mutants. One will then be notified with a quest update and Paladin Danse will show up (if not a companion) as the Sole Survivor exits this area to comment on the results.[verification overdue]
  • pcIcon pc Sometimes the Vertibird will not show up, and the quest marker will tell to take the Vertibird to Boston Airport. Saving and reloading may fix this.[verification overdue]
  • pcIcon pc If asking Paladin Danse to accompany for this mission then choose the previous companion instead, once securing Fort Strong, Paladin Danse may spawn on the lower level of Fort Strong as though he were with the player character all along.[verification overdue]
  • ps4Icon ps4 Sometimes when entering Fort Strong the elevator will be bugged. The elevator will descend upon entering but the doors will not open, trapping the player character inside indefinitely. Solution: Restart console and load a save aboard The Prydwen.[verification overdue]
