Always wondered about hush missions on unmarked silver C-130a's in 1960's. I was in 374th fms comm nav shop I think at the time we had three guys that crewed them out of our shop. It was all classified stuff at the time but sort of thought they supported lima site in Laos. Last day at Naha I got the pleasure to go to Kadena for a UHF radio problem seemed funny they sent a staff car to carry me and a good radio up island. When I got there I saw seven C-130's behind two or three fences all with armed air police and german shepherds I did have a clue. They finally got me to the plane with a broke radio and when they opened the crew door it became quite clear why all the security it was full of nukes. The seven planes were the stockpile of retailatory weapons if attacked alert crews scambled these aircraft so as not to lose second strike capability. I fixed the radio by then the staff car was gone and I had beg for a ride back to Naha great last day.
