ArcJet Systems

ArcJet Systems is a location in the Commonwealth in Fallout 4.

Background
ArcJet Systems was a pre-War technology company located in the greater Boston area. They produced electronics and rockets used by the USSA until 2077.

USSA contracts
ArcJet was able to secure two very lucrative contracts from the |USSA, one being the Deep range transmitter, the other a nuclear-powered rocket, the XMB booster engine, commissioned for the Mars Shot Project. Both projects were completed before 2077, however ArcJet only received payment for the Deep Range Transmitter project, as the rocket was delayed prior to The Great War for problems on the western front.

XMB booster engine
The XMB booster engine was a nuclear propulsion system developed by Dr Rory McClellan. The rocket was commissioned by the USSA as the main propulsion for the Mars Shot Project. ArcJet began developing the XMB Booster Engine in 2075, even before it had won the USSA contract. CEO Thomas Reinhardt, eager to deliver on its first Agency contract, hired Dr. Rory McClellan, a private military contractor, to help develop the Booster. Great progress was made in the first few months.

This fortune would be short lived, however. It was in March 2076 that the project reached a halt. Strict USSA guidelines meant that Dr. McClellan's booster was ten tons overweight. At the same time, the USSA began its public relations campaign, officially announcing the booster July 2076. This was much to the dismay of Thomas Reinhardt, who hid the setbacks from the press and government. The weight problem was solved in November 2076, just in time to begin preliminary testing. The rocket successfully passed preliminary tests, but was ultimately delayed by the events leading to The Great War.

Deep range transmitter
A transmitter designed before the Great War by ArcJet Systems to greatly boost the signal of transmissions, that was in theory capable of getting a signal from Mars to Earth in ten minutes.

Press and controversies
Following an announcement from the USSA, press flooded ArcJet systems looking for information and pictures of the newly developed rocket. On the day of the media reveal, a reporter, who had penetrated ArcJet security, infiltrated the test chamber immediately prior to a practice burn. The reporter was instantly incinerated. Fearing media fallout and the loss of his contract, Thomas Reinhardt had the incident covered up and the ashes disposed of. The incident was never disclosed to the public. When Doctor McLellan discovered this, he was about to reveal the truth to the media when Thomas Reinhardt threatened to kill him and his family.

Security
ArcJet became increasingly paranoid in the days leading to the Great War. Turret and surveillance systems were employed to keep information safe. Only employees with identification badges could move freely through the complex. Passwords were automatically changed by the main system, and sent via email to ArcJet employees.

Layout
A low building with massive internal damage, the building is a maze of collapsed floors and ceilings. Beneath the main building is a rocket engine test chamber. The rocket strangely is still functional and can be used to cook your enemies to a crisp.

Notable loot

 * Stealth Boy – There is one on the first floor, past a locked door (novice) in the south-east corner (middle section). To the right a collapsed floor leads up to the second floor and also to a room that's still on the first floor; the Stealth Boy is in a shelf in the corner.
 * Overdue book – Sitting on the large table in the meeting room, which is located behind a closed door off the hallway where you encounter three machine gun turrets attached to the ceiling.
 * Tesla Science Magazine issue #1 (+5% energy weapon critical damage) - Second floor, next to the CEO's terminal. You have to pass the same locked door as for the Stealth Boy but turn left and go up the stairs.
 * Deep range transmitter – Quest item for Call to Arms, located on a Synth in the upper floor control room after using the elevator in the rocket test area.
 * Junk Jet – Rocket test area, in the control room at the base of the rocket, on a bench beside a holotape from the creator.
 * Fat Man - Sitting on a desk inside the north room (Marked with a '2' on the right side of the door) in the ArcJet Engine Core section. NOTE: This can either be accessed going down from the top of the stairwell, or by getting onto the railing as soon as you enter the area with the engine and jumping to the walkway that leads to the room marked with a "2". The height of the railing should be easily sufficient to make it to the walkway as long as you make sure to sprint.
 * Mentats - There are two; Second floor bathroom to the NE on couch and one in a broken elevator by a skeleton.
 * Fusion core - Rocket test area, in the generator room behind the rocket control room.
 * Discarded ArcJet worklog - In the lab control room, on a desk next to a terminal and a globe in the middle of the room.

Appearances
ArcJet Systems only appears in Fallout 4.

Behind the scenes

 * ArcJet may be a reference to an engine produced by Lockheed Martin by the same name.

Bugs

 * In the ArcJet Engine Core section, on the second floor. There is a locked terminal in the room that displays expert required hacking, but is actually a master locked terminal.
 * P.A.M. can give the missions to kill Coursers (Railroad) in this location but you wont have access to most areas yet due to another companion mission not being completed yet. This will leave you unable to finish the mission.
