‘Iran stealth subs could lie in wait to hunt hostile aircraft carriers’

Our subs know what the surface weather is because we can hear the sound of rain drops, wind and waves on the ocean surface.

The reason we generally keep our subs out of the Persian Gulf is that it is so shallow and we have trouble avoiding detection. Ordinary satellite photos are a problem.

The other problem with the very warm waters of the Persian Gulf is that bacteria grows rapidly on any sub hull and is very difficult to remove. A one year tour with no time in cooler water to kill the bacteria requires dry dock sand blasting and “passivation” of the seams.

The Iranian subs are there 24/7 and will quickly degrade.

Sure, but sometimes it isn't all that effective either. [Russian intelligence buying models of U.S. equipment.]

Interesting story about the "F-19". I kinda suspected that the "Nautilus" story was just an Urban Legend, but evidently it did go on. I guess intelligence networks have to play all the angles.

What gave me a bit of a chill was that back in the '60s'70s, Russians were going to the Gedodetic Survey department with each week with $1,000 checks and buying up all their U.S. maps, starting with "A". I calmed down a bit when I saw a couple in my area were dated 1898.
