The New Avengers Facility is the primary base of the Avengers after the defeat of Ultron and the establishment of the team's new roster.
After the Avengers Civil War, Tony Stark continued to use the facility as his primary place of residence, and after selling Avengers Tower, moved all the equipment into the facility as well.
The facility was founded shortly after the aftermath of the Battle of Sokovia and end of the Ultron Offensive. The Avengers team was reformed, with Iron Man and Hawkeye leaving the team voluntarily, Thor leaving Earth, and Hulk going missing.
Many of the staff are former S.H.I.E.L.D. agents, such as Maria Hill or Nick Fury. In addition, the facility has the support of renowned scientists such as Erik Selvig and Helen Cho.
The base is used for scientific research, military training, weapons development and the New Avengers program. Vehicles and aircraft such as the Quinjet are also stationed at the facility.
