This Navaid is at an airport in the United States.
Its identifier is different than that of the airport, and it relates to the name of the company that first used that airport as a hub.
It's a former USAF base.
The city that it serves shares a name with two other U.S. cities with airline service, and one VOR!
Those three cities' airports all share two letters of their identifiers.
