Not true..I have seen them in AZ in storage.
They started cutting them up in 2007 and the last one was destroyed either late ‘09 or early ‘10. I remember reading the article about the last one being cut up because the guy who was cutting it up worked on them in the Navy and he was choked up about it.
Only survivors are completely gutted and mounted on sticks in front of bases or in museums.
I found an old FR post from 2007 saying it was a 3 year contract to get rid of all of them
