An interesting question would not be "Where are the Carriers?" but rather "Where are the Attack Submarines?.
Then one might consider where are some B-52's and B-1's......or even some B-2's.
Iranian Frigates have done better as artificial reefs than as combatants as I recall.
They certainly are not going to carry the day should they decide to start the game with a kick off.....that shall not end well for them militarily.
Presence alone is sufficient to allow them to project some limited power.....actual hostilities shall only cause them to. lose the game and project no power at all.
