....I don't know if this will be of any help, but it might provide you with some clues...pictures,videos....
There have been a few U.S.A.F bases that have been hit by tornado's here in the Midwest...most notably are Tinker AFB Ok. (the very first,ever, tornado forecast originated from here!), McConnell AFB Wichita, Ks. 1991 Andover tornado, Offutt AFB Omaha, Neb. 1970's???, might want to check Schilling air field (Army) in Salina, Ks. I think it may have been hit before it was decommissioned. I think that Ft.Riley (Army) in Ft. Riley Ks. has been hit...don't recall the dates. Another couple that come to mind are Richards Gebaur (USAF) 1957 Grandview,Mo. (Ks. City, Mo.) Ruskin Heights tornado and think that I read somewhere where Whiteman AFB in Knob Noster , Mo. had been hit...might be too recent for you as far as when it was hit.
Forbes Air Force Base (decommissioned in the early 70's) here in Topeka had sirens as it was a part of the Strategic Air Command during the Cold War. I have seen sirens on base, now know as Forbes field, but I doubt that they would be from the old siren system since the Kansas Army Air National Guard as well as the 170th Air Refueling wing of the Kansas Air National Guard now occupy quite a bit of the old air base as well as Heartland Park motor sports complex.
