It all depends on actual or potential threat assessment and efficient use of available resources . The threat is and has been NATO and American attacks from the South of Iran and Persian Gulf region , by their Navy and Air force . Building numerous surface ships , even in the Persian Gulf for Iran , is in my view a waste of resources . Iran can not match the American 500 ship navy , with a a dozen surface ships , in open water . Iran only needs blue - water ships in northern Indian Ocean , to fight pirates . Although this could be done cheaply with fast attack Boats , still Iran is wealthy enough to save the lives of a few sailors by sailing these larger ships . But Iran is not wealthy enough to engage symmetric gunship battles with the Yanks , 18-th century style ! The best policy is to build submarines for the Ocean , both Diesel and Nuclear and AIP fuel-cell to take out large numbers of American ships and launch cruise missiles near American coast with various warheads . Only for training purposes are these larger Ships useful in Caspian , especially if this use limits EM radiation leaks and detection of tactics by American underwater listening and spying stations . Think of it as shallow birthing pool , for the baby Sharks . Sure , if Russia has plenty of Ships , why not put one in Caspian . But even this Ship can not do Beach landing of vehicles and troops . Any realistic and conceivable threat in Caspian can be dealt with by cheaper and more available and varied resources , that Iran possesses . Used in more efficient and surgical way . Anti-piracy operation in Caspian is virtually unknown , and needs at most one ship !
