Requesting Permission to Come Aboard

While exploring the Charleston Neighborhood, you may be stopped by Lookout, a Mr. Handy robot at the foot of an ancient seafaring vessel called the USS Constitution, now embedded in buildings overlooking Boston Harbor. Locate the hull door in the ruined building the ship is sitting on, and work your way up through the interior to the exterior main deck.

Speak to Ironsides. Agree to help him assist in repairing his vessel.

Scurvy dogs from below! The ship is under attack from Scavengers. You must defend it. You can:

  • Prep the streets below with traps before boarding the vessel.
  • Fire the cannons by completing the circuit breaker and softening the targets below.
  • Attack with ranged or sniper weapons from the deck.
  • Use the aft rowboat to quickly descend and ascend, and charge at the foes. Or simply drop down if you have more robust armor on.

After the battle, speak to either the Bosun, the Navigator, or both. The next few objectives can be completed in either order.

Chosen by the Bosun

Head below deck and talk to the Bosun. You have three power cable wiring boxes to fix. You can:

  • Find a metal box (below deck) with three power cables in it, and use them to repair the cables.

Power Cables

(Jury Rig, Intelligence 3+) Salvage the replacement power cables without needing the power cables from the metal box. Then return to Bosun; he has another job for you (regarding the Power Relay Coil objective).

The Chips Are Down

Head up on deck and speak to Mr. Navigator. He requires you to obtain a guidance chip from some Scavengers and requests you don’t use force. But that’s up to you. Now go shopping.

Visit Mandy Stiles and her scavenger sidekick Davies at her store/hideout, close to the ship. Answer her how you wish. You can:

  • Agree to work with her to bring down Ironsides and his crew. This is recommended, as you can always change your mind later, and Mandy won’t be hostile. Take the guidance chip.
  • Agree to work with Ironsides. This is only recommended if you just want to help the ship’s crew. Kill everyone and take the guidance chip.
  • Ignore her, sneak into the ruined building behind her, and steal the guidance chip from the cabinet. If you’re spotted, Mandy and the Scavengers turn hostile.

NX-42 Guidance Chip

While you’re on shore leave, you should also visit Bunker Hill and purchase a power relay coil from Deb, if you don’t want to repair it on the ship.

Power Relay Coil

Return to the ship and head below deck. Access the power relay. You can:

  • Install the power relay coil you acquired.
  • (Repair, Intelligence 5+) Repair the damaged coil without needing to find a new one.

Then talk with the Bosun and conclude his tasks.

Head to the deck and activate the Core Guidance System. Speak to Mr. Navigator, who rewards you and gives you another job.

Bottlecaps (250): Installing Guidance Chip

Getting Guidance

Mr. Navigator requires a radar transmitter. You can repair the one on the ship or find a new one from a random location, such as the Poseidon Energy Turbine #18-F. Locate the steamer trunk at the location and obtain the following:

Poseidon Radar Transmitter

Return to the ship and head on deck to the guidance radar and begin fiddling with it. If you have the best Repair skill, you can fix this. Otherwise, install the new Poseidon Radar Transmitter.

Report in to Mr. Navigator for a reward; then you’re directed to talk to the captain.

Getting Your Bearings

Ironsides needs one last component to repair the USS Constitution: turbopump bearings. Find them at a nearby factory. After that, maybe he can tell you what the hell he’s up to. He gives you a key to enter his cabin to install the device.

Captain’s Quarters Key

Travel to the indicated (random) location; it is always one with a steamer trunk–sized crate to open. Rummage around inside after abating any immediate threats and grab the following:

FLL3 Turbopump Bearings

Optional: Losing Your Bearings

At this point, you have one of two plans to commit to:

  • Plan A: Return to the ship and install the turbopump bearings as Ironsides requested. This occurs whether you agreed to side with the Scavengers or not.
  • Plan B: Stop off at Mandy’s location, sabotage the turbopump first, and then install it. This is only available if you sided with the Scavengers earlier and kept your word to Mandy.

Return to Ironsides and speak to him about his next harebrained scheme. At this point, there are two possible conclusions: Plan A and B. You receive the following reward for installing the Turbopump:

Bottlecaps (500)

Plan A: Setting Sail!

Before the arguably insane Ironsides can start his plan, you have to fend off a last-ditch attack from the Scavengers.

Fend them off, optionally using the cannons, previously laid traps, and more devastating weapons in your arsenal—if Ironsides dies, the quest fails. After the Scavengers are dead,

speak to Ironsides, who grants you the following and has one last request: To fire up the auxiliary power.

Unique Weapon: Broadsider

Bottlecaps (1,500)

Leave the ship and ascend the ruins of the building the Scavengers attacked from, south of the street. Flip the circuit breaker and watch the voyage of the ship. Afterwards, if you’ve watched where the ship ended up, you can visit the new location and have another chat with Captain Ironsides, and receive a special Charisma-improving Lieutenant’s Hat, and the use of the Captain’s quarters.

Lieutenant’s Hat (and Captain’s Quarters)

Plan B: Engine Fail!

Did you sabotage the USS Constitution’s rockets? Now Ironsides needs more power before everything goes to hell. You should check in with Mandy Stiles before setting things in motion, and agree to her request to slay Ironsides.

Ascend the ruins of the building the Scavengers attacked from, south of the street. Flip the circuit breaker and watch the engines explode. Board the ship and defeat Ironsides and any other crew members you wish. Then return to Mandy, who promptly betrays you. Kill her and all other Scavengers, and loot the salvage for yourself, as your disastrous decisions finally catch up with you.
