The closure of RAF Mildenhall has been postponed until at least 2027.
The Suffolk base was set to be closed in 2023.
A US Air Force spokesman at RAF Mildenhall said: "All decisions for the European Infrastructure Consolidation effort that were announced in 2015 are continuing as planned.
"However, the estimated divestiture date of RAF Mildenhall is no earlier than 2027."
The decision to close the base was made in 2015.
However, in 2017, reports emerged that the US Department of Defense was reconsidering its plans.
In 2018, it was announced that more than 500 RAF and US Air Force personnel and their families would move to RAF Fairford in Gloucestershire within the next five years.
