Peterloo,
I invite you to go to this website
http://maps.google.com/ and type in "Bandar Abbas, Iran". On the western edge of the city is the naval base there, with probably half their fleet if not more.
1 airstrike and not a single vessel will be serviceable. It would take several hours for the fleet to be mobilised and start sailing, which would likely be hours too late in the event of an outbreak in hostilities. Unless they have advance warning, ie they decide to do something silly and sortie the fleet in advance...
