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.

In 2075, ArcJet began working on a nuclear-powered rocket, the XMB booster engine, in hopes of convincing the United States Space Administration to award them the lucrative contract for their Mars Shot Project. Despite the risk of starting work before the contract, it paid off when the USSA gave them both the contract for the booster engine and the contract for a deep range transmitter. 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. CEO Thomas Reinhardt promised the USSA to finish both projects by July 2077, a year before the expected launch date.

Eager to deliver on its first Agency contract, CEO Reinhardt hired Dr. Rory McClellan, a private military contractor, to lead the development of the XMB booster engine. Reinhardt also ordered head of security, Sam Brent, to double the facility's security and install automated security systems. By December, both of their projects were on schedule, and even under budget, and the USSA was discussing the possibility of other future projects.

In March 2076, the XMB suffered a setback when it was discovered that it was hundreds of tons overweight, setting them three to six months behind schedule. Reinhardt also became increasingly paranoid about security, having turrets installed in the office areas and requiring everyone to wear special identification badges or risk being fired upon. In July, the USSA announced the Mars Shot Project to the public, resulting in an increase of popularity and media coverage at ArcJet, but forcing Reinhardt to lie about their progress. In November, McClellan was able to fix the engine's weight issue, allowing ArcJet to finalize the project.

By 2077, ArcJet was able to complete the deep range transmitter project, allowing them to earn the proceeds from their contract. In February 2077, ArcJet planned to hold a press event to show off the first USSA test fire of the XMB booster engine. However, before the event, a reporter somehow managed to sneak into the core engine room and was accidentally vaporized by an engine test. The press event was cancelled and Reinhardt ordered Sam Brent to cover the death up to prevent them from losing their contract. By September, the USSA warned Reinhardt that they may have to delay the Mars Shot Project due to the conflicts overseas.

In October, Dr. McClellan discovered the cover up of the dead reporter and told Reinhardt he was going to inform the police. Reinhardt responded by threating to kill McClellan and his family if he told anyone. Despite this, McClellan still planned to take the video evidence to the press.

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 on a shelf in the corner, behind the ramp. There is also one in a locked safe, on the floor right above the first stealth boy.
 * An 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. (The CEO room is very close to a "computer server room" full of blue "1950's era super computers")
 * 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.
 * Technician's personal log - found on a table within ArcJet Systems engine core chamber, on a table in the maintenance area next to the Junk Jet.
 * 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.
 * Two Mentats – One in the second floor bathroom to the NE, on the couch. Another one by a skeleton in a broken elevator.
 * A 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 won't have access to most areas yet due to another companion mission not being completed yet. This will leave you unable to finish the mission.
