Site A was the former headquarters of United States Hulk Operations (a.k.a. Shadow Base), a secret anti-Hulk military branch. Scientists at Site A conducted research and experimentations on gamma mutates such as Del Frye and the Hulk himself.
Shadow Base was forced to relocate to Site B following an increase in public notoriety and Site A was subsequently abandoned. Site A was completely destroyed by the Hulk when he released massive amounts of excessive gamma radiation, causing a huge explosion.
- Several large aquariums and hamster runs stocked with gamma irradiated animals were built into the walls of Site A. This proved to be a serious design flaw as Joe Fixit, in Bruce Banner's body, simply smashed his way through an aquarium to reach a control room on the other side of a locked door. This was the decision of Dr. Jeffrey Clive, who thought having the gamma animals on full display would promote "work-life synergy."
