C-130 "strange" variants …. need help !!

Hi guys !!!

I’m once again searching something strange … A friend of mine is looking for further information(pictures, drawings, data, …) regarding “strange” – once proposed – variants of the C-130 !

He mentioned the AEW-Version, the “Floatplane”, … a version with a bigger fuselage (greater diameter) and one with a T-tail !!

Does anyone have some more information, … esp. links on these “waht-if” projects ???

Thanks in advance, Deino
