The 173rd Fighter Wing (173 FW) is a unit of the Oregon Air National Guard, stationed at Kingsley Field Air National Guard Base, Klamath Falls, Oregon.

The 173d Fighter Wing is responsible for training combat pilots and support personnel on the McDonnell Douglas F-15 Eagle (C and D models) for the active duty Air Force and the Air National Guard.

Initially flying early versions of the F-16 Fighting Falcon aircraft as a formal training unit (FTU), the F-16As and F-16Bs were retired in the late 1990s as their service life was ending.

The squadron began receiving F-15A and F-15B Eagles in 1998, upgrading to the F-15C and F-15D Eagle in 2004 as the A and B series aircraft were retired and continuing its mission as a fighter-interceptor training unit for the Air Force and the Air National Guard.
