"Area 51 is a S.H.I.E.L.D. base."
Phil Coulson[src]

Area 51 is a highly classified United States Air Force facility in Nevada and one of S.H.I.E.L.D.'s bases. In the 1950s, it was S.H.I.E.L.D.'s most secure base in the Western United States.


S.H.I.E.L.D. Base

Project Helius

"In 1955, there was a classified project at Area 51 called Helius."
Phil Coulson[src]

Area 51 was established as a United States Air Force facility, and by the 1950s, was also used by S.H.I.E.L.D. as one of its bases of operation. Around this time, Project Helius was conceived at Area 51 as an attempt for S.H.I.E.L.D. create an ion fusion reactor. Headed by Pascal Vega, numerous S.H.I.E.L.D. scientists lived at Area 51, while others would enter the base every day. However, Helius was eventually mothballed, as S.H.I.E.L.D. believed nothing on Earth was powerful enough to start the fusion reactor.[1]

Failed Raid

"Just when you think the internet can do some good in this world and band together to find some aliens, they fail all over again! Over a million people planned to attend the much-hyped raid on Area 51, but after the dust has settled: initial reports say that only a few dozen showed up!"
The Daily Bugle[src]

In 2024, over a million people were reportedly planning to raid Area 51 in a search for extraterrestrial life, but initial reports later said that only a few dozen showed up. J. Jonah Jameson from The Daily Bugle commented on the outlet that all these people failed to realize that the "real aliens are the super heroes", criticizing the Avengers and recalling all the controversy surrounding purchasable Chitauri technology on the black market in the aftermath of the Battle of New York.[2]

Alternate Universes


In an alternate universe, Area 51 was infiltrated by Chronicoms, who began manipulating Project Helius. The Area was then entered by Phil Coulson and Jemma Simmons, posing as Gerald Sharpe and Peggy Carter. Coulson and Simmons were given a tour by Pascal Vega, who showed them a scale model of the Helius. Simmons and Coulson then asked to interview the scientists, hoping to find the Chronicoms. While the scientists were questioned, Daniel Sousa arrived and caught Simmons in her lie, arrested her and Coulson.

Daisy Johnson went to Area 51 and posed as a CIA agent and went to Area 51. Sousa asked Johnson if her visit was about a report submitted regarding sleeper agents in S.H.I.E.L.D., while a Chronicom Hunter activated Helius, using itself as a battery. Melinda May and Yo-Yo Rodriguez activated smoke bombs to find the Chronicom, but froze once they found her, allowing her to escape. May and Rodriguez recovered and chased her while Simmons and Johnson attempted to activate an EMP Generator on the base. They were attacked by a second hunter, who Coulson fought. Simmons and Johnson activated the EMP, destroying Helius and killing the Chronicoms, as well as deactivating Coulson.[1]

Coulson was brought into an interrogation room and reactivated, finding that his vision was in black and white and that he had an inner monologue. Coulson recognized that it was the date Sousa was destined to die after delivering a package to Howard Stark. Coulson claimed to be Sousa's contact, and went with him to deliver the package.[3]
