The North American Aerospace Defense Command (NORAD) is mulling a change that would take fighter squadrons in Duluth and the state of Virginia off of 24-hour alert, reports The Associated Press.
The move will reportedly save millions of dollars while not compromising NORAD's ability to defend North America against 9/11 attacks.
Currently, there are 18 Air Force sites are on 24-hour alert.
Minnesota Public Radio reports that the information was released in a Government Accountability Office report on Thursday.
The change could save $73 million over five years if the Duluth and Joint Base Langley-Eustis, Va., sites are converted to part-time.
MPR says the 148th Fighter Wing in Duluth employs 1,044 Minnesota National Guard members.
The possible move is not related to the federal budget sequester that went into effect Friday.
A NORAD spokesman said a decision has not been made, and the Duluth and Virginia sites remain on 24-hour alert, The AP reports.
