Rory McClellan (or Roy, as spelled on his private terminal) was one of the foremost experts on nuclear physics working for the military before the Great War. By October 2075, McClellan was putting his talents to work for the United States military, though he considered it a waste of his talents: Working for the military was a horrible, never-ending grind of broken promises, slashed budgets and ridiculous deadlines. When Thomas Reinhardt, CEO of ArcJet Systems, offered him a job as project manager for the XMB Booster, he jumped on the opportunity. It finally allowed him to broaden his horizons and work on something he always dreamed of doing - helping send astronauts to Mars. With ArcJet money and McClellan's know-how, he was certain he could deliver a superior product to the United States Space Administration.
Unfortunately, his optimism did not survive the reality check. By March 2076 it was apparent that the booster they were developing was too heavy to fit within the USSA's guideline. Although the CEO was furious, he eventually calmed down and realized the futility of his anger. The two worked out a schedule together, managing to get USSA to extend the deadline. The anticipated delay was three to six months. Thanks to McClellan's teams and crunch, the delay was ultimately three months, culminating in an engine just 17 pounds under the USSA weight limit. The team celebrated in a local bar, cherishing the success of the project.
However, the first test fire went awry. Unbeknownst to McClellan, he incinerated a reporter who sneaked into the engine core before the photo shoot to commemorate the first test fire. McClellan fired the engine in a carbon burn-off pre-test for a few seconds, to ensure it worked properly. The fire turned the reporter into ash. Reinhardt cancelled the event and had Sam Brent, ArcJet's head of security, bury the evidence under the guise of a security breach. McClellan would not discover the truth until he went through all the recordings of the test firings of the XMB in October 2077. The tape showed the reporter running across the bottom of the ArcJet engine core seconds before the booster ignited. McClellan confronted the CEO, who told him the truth about the incident and the cover-up. Then, when McClellan said that he would notify the police and the press, McClellan threatened both him and his family with reprisal. Though intimidated by the brazen threat, McClellan resolved to blow the whistle on the matter. Unfortunately, he decided to did so on the eve of the Great War, which rendered his CEO's crimes meaningless.
Rory McClellan is mentioned only in Fallout 4.
