No, let's not use cope here, Iran have only limited means of contesting the seas.
When the US did the Millenium Challenge wargame Iran was supposed to only have the Silkworm anti-ship missile. Which did not have enough range to cover the entire Persian Gulf if launched from the coastline. Which is why the guy playing as Iran made them be launched from boats.
The Silkworm is a clone of the P-15 Termit which is a missile with 40-80 km range depending on version. The missiles weight 2580 kg each which is why they say in the discussion it would have been impossible to carry them in the small boats he used in the simulation.
Well, the thing is, Iran today has the Nasr-1 anti-ship missile with 35 km range but that missile only weights 350 kg. Which can be definitively carried on fast small boats.
They also have the Qader cruise missile with up to 300 km range.
And finally like I said they have the anti-ship ballistic missiles with up to 700 km range.
The Persian Gulf at its widest extent from the Iranian coastline isn't even 300 km wide. So the Iranians can cover the entire Persian Gulf with land based missiles just like I said. For the Iranians hitting a ship transiting the Persian Gulf it would be like shooting fish in a barrel.
As for communications, Iran has connected all its cities with fiber optic links which would be really hard to intercept communications from, and they have 90% 4G phone coverage. That is just the civilian angle of things.
What is way more likely is that the US would try to bomb Iran from either Turkiye or Diego Garcia.
