Back in 1996 when I was on a pig boat doing surveillanc off the coast of "none-of-your-business" I remember intel that those Kilo's were welded to the pier. Something about cold water boats not lasting very long in the warm waters of the gulf. Heat exchangers don't exchange much heat in that water.

when I was on a pig boat doing surveillance.....

"Pig boat"? You mean a diesel boat? I thought the USN hadn't had any diesels in the inventory since they retired Albacore and the sorrowful quartet of "Harder, Darter, Trigger, Trout, / Always in and never out."

If the Iranian "Kilos" are no longer serviceable, I'm glad to hear it -- though I never heard of water temperature shortening a submarine's service life. Hard living maybe would, but I never heard that about tropical waters.
