There's a bunch of F-105 tanks down at the Air and Space Museum next to Davis Monthan AFB. I'm sure they'll let me measure one next time I'm down that way. There were three tanks assigned to the Thud IIRC a 390 USG internal bay tank non ejectable, a 450 USG centerline AND inner wing hardpoint slung tank, and a 650 USG centerline hardpoint slung tank. To verify you want the most common one the 450 USG external drop tank?

ive looked thru 6 105 pdfs i have but no measurements...best i have is Republics own measurements of the G and guess you could scale it to find measurements in max. if it comes to it.

The 450 gal wing tanks came in 2 variants. One with integral pylon and one for mounting to the existing inboard pylon.

I called down there and the F-105 they have is being refurbished for display, off limits to the public at the moment. Maybe these will help you scale a tank based off your model?

Hello  ravenclaw_007,

I have searched and like all of you didn't find anything worth reporting.  Therefore I asked one of my friends who happen to have a model to scale of the F-105B Late with 450 wing tanks moded to scale, so I have asked him to send me the file (not the best model but It will do I hope).  please find attached the file and some photos of the measurement hope that will help you.

Thanks for the help

i measured and compared a lot of scale drawings and i think the dimensions are about 27 inches ( 685,8 mm ) in diameter and 278 inches ( 7061,2 mm ) in length for the drop tank with out the fins

will try it and see if it fits

Hi Ravenclaw, 

Just as a point of comparison, here is a 300-gal reference
