The NX-42 guidance chip is a miscellaneous quest item in Fallout 4.


An orange chip card, to insert in the core guidance system on the USS Constitution.


  • If siding with Ironsides - in a file cabinet inside the scavenger's camp, west of the USS Constitution.
  • If siding with the scavengers - the scavengers freely give the chip and ask you to bring them any equipment the ship requires, so they can sabotage it.
