CarolC, I did see those, but one has nothing at all I could find about this alleged "deployment", one is from the same blogger, one seems to be copying information (in abbreviated form, but otherwise word-for-word) from that blogger, and the fourth quotes unidentified "military sources".

Perhaps I am unnecessarily picky, but these constitute neither indications nor evidence for me. Where are the satellite photographs? Where are the radio transcripts of blockading messages to shipping in the Gulf? Where are the bootlegged email messages from sailors on the ships? Where are the protests from blockaded ship owners (that would be the oil companies, of course) and from poor Iran, cut off from the outside world.
