Iran's Naval Tactics?

Described as a "Doctrine of Asymmetric Naval Warfare" here:

...{T}he Iranian concept of Alavi/Ashurai warfare relies not just on spiritual commitment, but also on high-tech weaponry and innovative tactics—a combination employed to great effect on the ground in southern Lebanon by Iran’s protege, the Lebanese Shiite Hizballah, in its war with Israel this summer.

The article goes on to cover the Iranian concept of "dispersed swarming" by its small combatants:

Dispersed swarming tactics are most successful when attackers can elude detection through concealment and mobility, employ stand-off firepower, and use superior situational awareness (intelligence), enabling them to find and engage the enemy first. This accounts for a number of trends in Iranian naval force development in the past two decades. The first is the acquisition and development of small, fast weapons platforms—particularly lightly armed small boats and missile-armed fast-attack craft; extended- and long-range shore- and sea-based antiship missiles; midget and diesel attack submarines (for intelligence gathering, covert mine laying, naval special warfare, and conventional combat operations); low-signature reconnaissance and combat unmanned aerial vehicles (UAVs); and the adaptation of the Shahab-3 medium-range surface-to-surface missile armed with a cluster warhead reportedly carrying 1,400 bomblets, for use against enemy naval bases and carrier battle groups.

ANd they have a plan:

In wartime, Iranian naval forces would seek to close the Strait of Hormuz and destroy enemy forces bottled up in the Persian Gulf; therefore speed and surprise would be key. Iranian naval forces would seek to identify and attack the enemy’s centers of gravity as quickly as possible and inflict maximum losses before contact with subordinate units were lost as a result of enemy counterattacks. Geography is Iran’s ally.

And don't forget the stealth flying boats (pictured).
